Subject: MPPA - The project compiles.

Supports very simple programs that load integer immediates. It starts
the main, loads integer in registers, and return correctly.

Addition in Mach not yet supported, but should not be hard to add them.

Function calls are not yet supported.

The ABI for now is the same as the RiscV, with a small twist: $ra is
first loaded in a user register, then this user register is pushed
(instead of pushing $ra straight away).

Subject: MPPA - Oshrximm + Mgetparam + FP is GPR10 + bug

Added Oshrximm and Mgetparam -> mmult.c divide & conqueer generates

FP is now GPR10 instead of being a mix of GPR30 and GPR32

Corrected a bug where Pgoto and Pj_l were given the same interpretation,
where in fact there's a fundamental difference : Pgoto is supposed to
have a function name (symbol), while Pj_l is supposed to have a label
name (print_label). This led to having undefinite labels in the code.

+MMULT
+=====
+
+Examples of matrix multiplication using different methods.
+
+We compute matrix multiplication using column-based matrix multiplication, then row-based, and finally block based.
+
+The test verifies that the result is the same on the three methods. If it is the same, 0 will be returned.
+
+The following commands can be run inside the folder:
+
+- `make`: produces the unitary test binaries
+  - `mmult-test-gcc-x86` : binary from gcc on x86
+  - `mmult-test-k1c-x86` : binary from gcc on k1c
+  - `mmult-test-ccomp-x86` : binary from ccomp on k1c
+- `make test`: tests the return value of the binaries produced by gcc.
+- `make check`: tests the return value of the binary produced by CompCert.

+PRNG
+====
+
+This is a simple Pseudo Random Number Generator.
+
+`prng.c` contains a simple unitary test that compares the sum of the "bytewise sum"
+of 1000 generated numbers to a hardcoded result, that is the one obtained with
+`gcc -O2` on a x86 processor, and returns 0 if the result is correct.
+
+The following commands can be run inside that folder:
+
+- `make`: produces the unitary test binaries
+  - `prng-test-gcc-x86` : binary from gcc on x86
+  - `prng-test-k1c-x86` : binary from gcc on k1c
+  - `prng-test-ccomp-x86` : binary from ccomp on k1c
+- `make test`: tests the return value of the binaries produced by gcc.
+- `make check`: tests the return value of the binary produced by CompCert.

+PRNG
+====
+
+This is a simple Pseudo Random Number Generator.
+
+`prng.c` contains a simple unitary test that compares the sum of the "bytewise sum"
+of 1000 generated numbers to a hardcoded result, that is the one obtained with
+`gcc -O2` on a x86 processor, and returns 0 if the result is correct.
+
+The following commands can be run inside that folder:
+
+- `make`: produces the unitary test binaries
+  - `prng-test-gcc-x86` : binary from gcc on x86
+  - `prng-test-k1c-x86` : binary from gcc on k1c
+  - `prng-test-ccomp-x86` : binary from ccomp on k1c
+- `make test`: tests the return value of the binaries produced by gcc.
+- `make check`: tests the return value of the binary produced by CompCert.

+### Tiny AES in C
+
+This is a small and portable implementation of the AES [ECB](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Electronic_Codebook_.28ECB.29), [CTR](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_.28CTR.29) and [CBC](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Cipher_Block_Chaining_.28CBC.29) encryption algorithms written in C.
+
+You can override the default key-size of 128 bit with 192 or 256 bit by defining the symbols AES192 or AES256 in `aes.h`.
+
+The API is very simple and looks like this (I am using C99 `<stdint.h>`-style annotated types):
+
+```C
+/* Initialize context calling one of: */
+void AES_init_ctx(struct AES_ctx* ctx, const uint8_t* key);
+void AES_init_ctx_iv(struct AES_ctx* ctx, const uint8_t* key, const uint8_t* iv);
+
+/* ... or reset IV at random point: */
+void AES_ctx_set_iv(struct AES_ctx* ctx, const uint8_t* iv);
+
+/* Then start encrypting and decrypting with the functions below: */
+void AES_ECB_encrypt(struct AES_ctx* ctx, uint8_t* buf);
+void AES_ECB_decrypt(struct AES_ctx* ctx, uint8_t* buf);
+
+void AES_CBC_encrypt_buffer(struct AES_ctx* ctx, uint8_t* buf, uint32_t length);
+void AES_CBC_decrypt_buffer(struct AES_ctx* ctx, uint8_t* buf, uint32_t length);
+
+/* Same function for encrypting as for decrypting in CTR mode */
+void AES_CTR_xcrypt_buffer(struct AES_ctx* ctx, uint8_t* buf, uint32_t length);
+```
+
+Note: 
+ * No padding is provided so for CBC and ECB all buffers should be multiples of 16 bytes. For padding [PKCS7](https://en.wikipedia.org/wiki/Padding_(cryptography)#PKCS7) is recommendable.
+ * ECB mode is considered unsafe for most uses and is not implemented in streaming mode. If you need this mode, call the function for every block of 16 bytes you need encrypted. See [wikipedia's article on ECB](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Electronic_Codebook_(ECB)) for more details.
+
+You can choose to use any or all of the modes-of-operations, by defining the symbols CBC, CTR or ECB. See the header file for clarification.
+
+C++ users should `#include` [aes.hpp](https://github.com/kokke/tiny-AES-c/blob/master/aes.hpp) instead of [aes.h](https://github.com/kokke/tiny-AES-c/blob/master/aes.h)
+
+There is no built-in error checking or protection from out-of-bounds memory access errors as a result of malicious input.
+
+The module uses less than 200 bytes of RAM and 1-2K ROM when compiled for ARM, but YMMV depending on which modes are enabled.
+
+It is one of the smallest implementations in C I've seen yet, but do contact me if you know of something smaller (or have improvements to the code here). 
+
+I've successfully used the code on 64bit x86, 32bit ARM and 8 bit AVR platforms.
+
+
+GCC size output when only CTR mode is compiled for ARM:
+
+    $ arm-none-eabi-gcc -Os -DCBC=0 -DECB=0 -DCTR=1 -c aes.c

+# sha-2 [![Build Status](https://travis-ci.org/amosnier/sha-2.svg?branch=master)](https://travis-ci.org/amosnier/sha-2)
+
+https://github.com/amosnier/sha-2
+
+## Contents
+
+SHA-2 algorithm implementations.
+
+At the moment, only SHA-256 is implemented.
+
+## Design criteria
+
+- Easy to test, include in any project, compile and link.
+
+- ANSI C with as little specific C99 as possible (e.g. extended
+  integer types are used, but not bool).
+
+- Portable. Makes no assumptions on the target system's endianess or
+  word size.
+
+- The SHA-256 implementation is a straightforward implementation of
+  the algorithm specified on
+  [Wikipedia](https://en.wikipedia.org/wiki/SHA-2).
+
+## Notes
+
+The Makefile is as minimal as possible. No effort was put into making
+it general. Its purpose is mainly to ease testing for the developer's
+host machine. The actual implementation is however extremely easy to
+include in any project, may it use GNU make or any other build tool.
+
+## Code review
+
+This code has been reviewed at [Stack Exchange CODE
+REVIEW](https://codereview.stackexchange.com/questions/182812/self-contained-sha-256-implementation-in-c),
+and the implementation has been improved accordingly.
+
+## Testing
+
+Testing is continuously performed on Travis CI (see above).
+
+Apart from that, the implementation has been successfully tested on an x86-64 machine
+under Linux as well as on a 16-bit DSP. On the x86-64 machine, all the
+available NIST test vectors where successfully tested ([SHA-256
+examples](https://csrc.nist.gov/CSRC/media/Projects/Cryptographic-Standards-and-Guidelines/documents/examples/SHA256.pdf)
+and [SHA-2 Additional
+examples](https://csrc.nist.gov/CSRC/media/Projects/Cryptographic-Standards-and-Guidelines/documents/examples/SHA2_Additional.pdf),
+plus a few others).

+
+## Reference implementation
+
+I had missed that when I made this implementation but [RFC 6234, chapter 8](https://tools.ietf.org/html/rfc6234#section-8) actually includes a reference implementation in C that is (at least in ambition) broader in scope than this one. I have however neither compiled nor tested it.

+
+* ADC code works again (spotted by Himanshu Jain)
+* include into R projects (with Christoph Muessel) (--rcode)
+* fixed 'undefined' + 'ptrdiff_' issues (thanks to Christoph Muessel)
+* added 'picosat_set_interrupt' and '-a <alarm>' command line option
+* fixed various issues pointed out by Stefan Hengelein:
+  - fixed incremental usage of 'picosat_adjust'
+  - added CPP fixes (STATS, NO_BINARY_CLAUSE versus TRACE mix-ups)
+  - removed redundant explicit set to zero on reset
+* fixed various usage bugs with 'picomus' (thanks to Stefan Hengelein)

+* added 'picosat_add_arg' and 'picosat_add_lits'
+
+* '--plain' and 'picosat_set_plain' to disable failed literal probing
+
+* new '#define PICOSAT_REENTRANT_API' in 'picosat.h'
+
+* added manager so no more global variables
+  (allows multiple instances, requires manager object)
+
+news for release 951 since 941
+------------------------------
+
+* cleaned up code (based on comments by Donald Knuth)
+
+* lreduce=O(conflicts^.5)
+

+* added All-SAT mode ('--all' command line option)
+
+* statistics include time spent in failed literal preprocessing (probing)
+
+* 'picosat_failed_context' for 'push & pop'
+   (and tested failed assumptions for 'push & pop')
+
+* 'picosat_simplify' for forced garbage collection
+
+* undefined NFL, defined NADC (= failed literals on, ADC's off)
+
+* 'picosat_push' and 'picosat_pop' (beta version)
+
+* fixed some issues related to binary clause handling and 
+  generating list of failed assumptions
+
+news for release 936 since 935
+------------------------------
+
+* simple minimal unsatisfiable core (MUS) extractor 'picomus'
+  (example for using 'picosat_mus_assumptions' and 'picosat_coreclause')
+
+* added 'picosat_mus_assumptions'
+
+* added 'picosat_{set_}propagations'

+
+* switched from inner/outer to Luby style restart scheduling
+
+* less agressive reduce schedule
+
+* replaced watched literals with head and tail pointers
+
+* add 'picosat_failed_assumption', which allows to avoid tracing and core
+  generation, if one is only interested in assumptions in the core
+
+* fixed a BUG in the generic iterator code of clauses
+  (should rarely happen unless you use a very sophisticated malloc lib)
+
+news for release 846 since 632
+------------------------------
+

+crypto-algorithms
+=================
+
+https://github.com/B-Con/crypto-algorithms/
+
+About
+---
+These are basic implementations of standard cryptography algorithms, written by Brad Conte (brad@bradconte.com) from scratch and without any cross-licensing. They exist to provide publically accessible, restriction-free implementations of popular cryptographic algorithms, like AES and SHA-1. These are primarily intended for educational and pragmatic purposes (such as comparing a specification to actual implementation code, or for building an internal application that computes test vectors for a product). The algorithms have been tested against standard test vectors.
+
+This code is released into the public domain free of any restrictions. The author requests acknowledgement if the code is used, but does not require it. This code is provided free of any liability and without any quality claims by the author.
+
+Note that these are *not* cryptographically secure implementations. They have no resistence to side-channel attacks and should not be used in contexts that need cryptographically secure implementations.
+
+These algorithms are not optimized for speed or space. They are primarily designed to be easy to read, although some basic optimization techniques have been employed.
+
+Building
+---
+The source code for each algorithm will come in a pair of a source code file and a header file. There should be no inter-header file dependencies, no additional libraries, no platform-specific header files, or any other complicating matters. Compiling them should be as easy as adding the relevent source code to the project.

+
+
+OVERVIEW
+========
+
+This package contains C software to implement JPEG image compression and
+decompression.  JPEG (pronounced "jay-peg") is a standardized compression
+method for full-color and gray-scale images.  JPEG is intended for compressing
+"real-world" scenes; line drawings, cartoons and other non-realistic images
+are not its strong suit.  JPEG is lossy, meaning that the output image is not
+exactly identical to the input image.  Hence you must not use JPEG if you
+have to have identical output bits.  However, on typical photographic images,
+very good compression levels can be obtained with no visible change, and
+remarkably high compression levels are possible if you can tolerate a
+low-quality image.  For more details, see the references, or just experiment
+with various compression settings.
+
+This software implements JPEG baseline, extended-sequential, and progressive
+compression processes.  Provision is made for supporting all variants of these
+processes, although some uncommon parameter settings aren't implemented yet.
+For legal reasons, we are not distributing code for the arithmetic-coding
+variants of JPEG; see LEGAL ISSUES.  We have made no provision for supporting
+the hierarchical or lossless processes defined in the standard.
+
+We provide a set of library routines for reading and writing JPEG image files,
+plus two sample applications "cjpeg" and "djpeg", which use the library to
+perform conversion between JPEG and some other popular image file formats.
+The library is intended to be reused in other applications.
+
+In order to support file conversion and viewing software, we have included
+considerable functionality beyond the bare JPEG coding/decoding capability;
+for example, the color quantization modules are not strictly part of JPEG
+decoding, but they are essential for output to colormapped file formats or
+colormapped displays.  These extra functions can be compiled out of the
+library if not required for a particular application.  We have also included
+"jpegtran", a utility for lossless transcoding between different JPEG
+processes, and "rdjpgcom" and "wrjpgcom", two simple applications for
+inserting and extracting textual comments in JFIF files.
+
+The emphasis in designing this software has been on achieving portability and
+flexibility, while also making it fast enough to be useful.  In particular,
+the software is not intended to be read as a tutorial on JPEG.  (See the
+REFERENCES section for introductory material.)  Rather, it is intended to
+be reliable, portable, industrial-strength code.  We do not claim to have
+achieved that goal in every aspect of the software, but we strive for it.
+
+We welcome the use of this software as a component of commercial products.
+No royalty is required, but we do ask for an acknowledgement in product
+documentation, as described under LEGAL ISSUES.
+
+
+LEGAL ISSUES
+============
+
+In plain English:
+
+1. We don't promise that this software works.  (But if you find any bugs,
+   please let us know!)
+2. You can use this software for whatever you want.  You don't have to pay us.
+3. You may not pretend that you wrote this software.  If you use it in a
+   program, you must acknowledge somewhere in your documentation that
+   you've used the IJG code.
+
+In legalese:
+
+The authors make NO WARRANTY or representation, either express or implied,
+with respect to this software, its quality, accuracy, merchantability, or
+fitness for a particular purpose.  This software is provided "AS IS", and you,
+its user, assume the entire risk as to its quality and accuracy.
+
+This software is copyright (C) 1991-1998, Thomas G. Lane.
+All Rights Reserved except as specified below.
+
+Permission is hereby granted to use, copy, modify, and distribute this
+software (or portions thereof) for any purpose, without fee, subject to these
+conditions:
+(1) If any part of the source code for this software is distributed, then this
+README file must be included, with this copyright and no-warranty notice
+unaltered; and any additions, deletions, or changes to the original files
+must be clearly indicated in accompanying documentation.
+(2) If only executable code is distributed, then the accompanying
+documentation must state that "this software is based in part on the work of
+the Independent JPEG Group".
+(3) Permission for use of this software is granted only if the user accepts
+full responsibility for any undesirable consequences; the authors accept
+NO LIABILITY for damages of any kind.
+
+These conditions apply to any software derived from or based on the IJG code,
+not just to the unmodified library.  If you use our work, you ought to
+acknowledge us.
+
+Permission is NOT granted for the use of any IJG author's name or company name
+in advertising or publicity relating to this software or products derived from
+it.  This software may be referred to only as "the Independent JPEG Group's
+software".
+
+We specifically permit and encourage the use of this software as the basis of
+commercial products, provided that all warranty or liability claims are
+assumed by the product vendor.
+
+
+ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
+sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
+ansi2knr.c is NOT covered by the above copyright and conditions, but instead
+by the usual distribution terms of the Free Software Foundation; principally,
+that you must include source code if you redistribute it.  (See the file
+ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
+of any program generated from the IJG code, this does not limit you more than
+the foregoing paragraphs do.
+
+The Unix configuration script "configure" was produced with GNU Autoconf.
+It is copyright by the Free Software Foundation but is freely distributable.
+The same holds for its supporting scripts (config.guess, config.sub,
+ltconfig, ltmain.sh).  Another support script, install-sh, is copyright
+by M.I.T. but is also freely distributable.
+
+It appears that the arithmetic coding option of the JPEG spec is covered by
+patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
+legally be used without obtaining one or more licenses.  For this reason,
+support for arithmetic coding has been removed from the free JPEG software.
+(Since arithmetic coding provides only a marginal gain over the unpatented
+Huffman mode, it is unlikely that very many implementations will support it.)
+So far as we are aware, there are no patent restrictions on the remaining
+code.
+
+The IJG distribution formerly included code to read and write GIF files.
+To avoid entanglement with the Unisys LZW patent, GIF reading support has
+been removed altogether, and the GIF writer has been simplified to produce
+"uncompressed GIFs".  This technique does not use the LZW algorithm; the
+resulting GIF files are larger than usual, but are readable by all standard
+GIF decoders.
+
+We are required to state that
+    "The Graphics Interchange Format(c) is the Copyright property of
+    CompuServe Incorporated.  GIF(sm) is a Service Mark property of
+    CompuServe Incorporated."
+
+
+REFERENCES
+==========
+
+We highly recommend reading one or more of these references before trying to
+understand the innards of the JPEG software.
+
+The best short technical introduction to the JPEG compression algorithm is
+	Wallace, Gregory K.  "The JPEG Still Picture Compression Standard",
+	Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
+(Adjacent articles in that issue discuss MPEG motion picture compression,
+applications of JPEG, and related topics.)  If you don't have the CACM issue
+handy, a PostScript file containing a revised version of Wallace's article is
+available at ftp://ftp.uu.net/graphics/jpeg/wallace.ps.gz.  The file (actually
+a preprint for an article that appeared in IEEE Trans. Consumer Electronics)
+omits the sample images that appeared in CACM, but it includes corrections
+and some added material.  Note: the Wallace article is copyright ACM and IEEE,
+and it may not be used for commercial purposes.
+
+A somewhat less technical, more leisurely introduction to JPEG can be found in
+"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by
+M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1.  This book provides
+good explanations and example C code for a multitude of compression methods
+including JPEG.  It is an excellent source if you are comfortable reading C
+code but don't know much about data compression in general.  The book's JPEG
+sample code is far from industrial-strength, but when you are ready to look
+at a full implementation, you've got one here...
+
+The best full description of JPEG is the textbook "JPEG Still Image Data
+Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published
+by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1.  Price US$59.95, 638 pp.
+The book includes the complete text of the ISO JPEG standards (DIS 10918-1
+and draft DIS 10918-2).  This is by far the most complete exposition of JPEG
+in existence, and we highly recommend it.
+
+The JPEG standard itself is not available electronically; you must order a
+paper copy through ISO or ITU.  (Unless you feel a need to own a certified
+official copy, we recommend buying the Pennebaker and Mitchell book instead;
+it's much cheaper and includes a great deal of useful explanatory material.)
+In the USA, copies of the standard may be ordered from ANSI Sales at (212)
+642-4900, or from Global Engineering Documents at (800) 854-7179.  (ANSI
+doesn't take credit card orders, but Global does.)  It's not cheap: as of
+1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7%
+shipping/handling.  The standard is divided into two parts, Part 1 being the
+actual specification, while Part 2 covers compliance testing methods.  Part 1
+is titled "Digital Compression and Coding of Continuous-tone Still Images,
+Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS
+10918-1, ITU-T T.81.  Part 2 is titled "Digital Compression and Coding of
+Continuous-tone Still Images, Part 2: Compliance testing" and has document
+numbers ISO/IEC IS 10918-2, ITU-T T.83.
+
+Some extensions to the original JPEG standard are defined in JPEG Part 3,
+a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84.  IJG
+currently does not support any Part 3 extensions.
+
+The JPEG standard does not specify all details of an interchangeable file
+format.  For the omitted details we follow the "JFIF" conventions, revision
+1.02.  A copy of the JFIF spec is available from:
+	Literature Department
+	C-Cube Microsystems, Inc.
+	1778 McCarthy Blvd.
+	Milpitas, CA 95035
+	phone (408) 944-6300,  fax (408) 944-6314
+A PostScript version of this document is available by FTP at
+ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz.  There is also a plain text
+version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing
+the figures.
+
+The TIFF 6.0 file format specification can be obtained by FTP from
+ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz.  The JPEG incorporation scheme
+found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.
+IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6).
+Instead, we recommend the JPEG design proposed by TIFF Technical Note #2
+(Compression tag 7).  Copies of this Note can be obtained from ftp.sgi.com or
+from ftp://ftp.uu.net/graphics/jpeg/.  It is expected that the next revision
+of the TIFF spec will replace the 6.0 JPEG design with the Note's design.
+Although IJG's own code does not support TIFF/JPEG, the free libtiff library
+uses our library to implement TIFF/JPEG per the Note.  libtiff is available
+from ftp://ftp.sgi.com/graphics/tiff/.

+ARCHIVE LOCATIONS
+=================
+
+The "official" archive site for this software is ftp.uu.net (Internet
+address 192.48.96.9).  The most recent released version can always be found
+there in directory graphics/jpeg.  This particular version will be archived
+as ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz.  If you don't have
+direct Internet access, UUNET's archives are also available via UUCP; contact
+help@uunet.uu.net for information on retrieving files that way.
+
+Numerous Internet sites maintain copies of the UUNET files.  However, only
+ftp.uu.net is guaranteed to have the latest official version.
+
+You can also obtain this software in DOS-compatible "zip" archive format from
+the SimTel archives (ftp://ftp.simtel.net/pub/simtelnet/msdos/graphics/), or
+on CompuServe in the Graphics Support forum (GO CIS:GRAPHSUP), library 12
+"JPEG Tools".  Again, these versions may sometimes lag behind the ftp.uu.net
+release.
+
+The JPEG FAQ (Frequently Asked Questions) article is a useful source of
+general information about JPEG.  It is updated constantly and therefore is
+not included in this distribution.  The FAQ is posted every two weeks to
+Usenet newsgroups comp.graphics.misc, news.answers, and other groups.
+It is available on the World Wide Web at http://www.faqs.org/faqs/jpeg-faq/

+
+RELATED SOFTWARE
+================
+
+Numerous viewing and image manipulation programs now support JPEG.  (Quite a
+few of them use this library to do so.)  The JPEG FAQ described above lists
+some of the more popular free and shareware viewers, and tells where to
+obtain them on Internet.
+
+If you are on a Unix machine, we highly recommend Jef Poskanzer's free
+PBMPLUS software, which provides many useful operations on PPM-format image
+files.  In particular, it can convert PPM images to and from a wide range of
+other formats, thus making cjpeg/djpeg considerably more useful.  The latest
+version is distributed by the NetPBM group, and is available from numerous
+sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/.
+Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is;
+you are likely to have difficulty making it work on any non-Unix machine.
+
+A different free JPEG implementation, written by the PVRG group at Stanford,
+is available from ftp://havefun.stanford.edu/pub/jpeg/.  This program
+is designed for research and experimentation rather than production use;
+it is slower, harder to use, and less portable than the IJG code, but it
+is easier to read and modify.  Also, the PVRG code supports lossless JPEG,
+which we do not.  (On the other hand, it doesn't do progressive JPEG.)
+
+
+FILE FORMAT WARS
+================
+
+Some JPEG programs produce files that are not compatible with our library.
+The root of the problem is that the ISO JPEG committee failed to specify a
+concrete file format.  Some vendors "filled in the blanks" on their own,
+creating proprietary formats that no one else could read.  (For example, none
+of the early commercial JPEG implementations for the Macintosh were able to
+exchange compressed files.)
+
+The file format we have adopted is called JFIF (see REFERENCES).  This format
+has been agreed to by a number of major commercial JPEG vendors, and it has
+become the de facto standard.  JFIF is a minimal or "low end" representation.
+We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
+Technical Note #2) for "high end" applications that need to record a lot of
+additional data about an image.  TIFF/JPEG is fairly new and not yet widely
+supported, unfortunately.
+
+The upcoming JPEG Part 3 standard defines a file format called SPIFF.
+SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
+be able to read the most common variant of SPIFF.  SPIFF has some technical
+advantages over JFIF, but its major claim to fame is simply that it is an
+official standard rather than an informal one.  At this point it is unclear
+whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
+standard.  IJG intends to support SPIFF once the standard is frozen, but we
+have not decided whether it should become our default output format or not.
+(In any case, our decoder will remain capable of reading JFIF indefinitely.)
+
+Various proprietary file formats incorporating JPEG compression also exist.
+We have little or no sympathy for the existence of these formats.  Indeed,
+one of the original reasons for developing this free software was to help
+force convergence on common, open format standards for JPEG files.  Don't
+use a proprietary file format!
+
+
+TO DO
+=====
+
+The major thrust for v7 will probably be improvement of visual quality.
+The current method for scaling the quantization tables is known not to be
+very good at low Q values.  We also intend to investigate block boundary
+smoothing, "poor man's variable quantization", and other means of improving
+quality-vs-file-size performance without sacrificing compatibility.
+
+In future versions, we are considering supporting some of the upcoming JPEG
+Part 3 extensions --- principally, variable quantization and the SPIFF file
+format.
+
+As always, speeding things up is of great interest.
+
+Please send bug reports, offers of help, etc. to jpeg-info@uunet.uu.net.

+.TH ANSI2KNR 1 "19 Jan 1996"
+.SH NAME
+ansi2knr \- convert ANSI C to Kernighan & Ritchie C
+.SH SYNOPSIS
+.I ansi2knr
+[--varargs] input_file [output_file]
+.SH DESCRIPTION
+If no output_file is supplied, output goes to stdout.
+.br
+There are no error messages.
+.sp
+.I ansi2knr
+recognizes function definitions by seeing a non-keyword identifier at the left
+margin, followed by a left parenthesis, with a right parenthesis as the last
+character on the line, and with a left brace as the first token on the
+following line (ignoring possible intervening comments).  It will recognize a
+multi-line header provided that no intervening line ends with a left or right
+brace or a semicolon.  These algorithms ignore whitespace and comments, except
+that the function name must be the first thing on the line.
+.sp
+The following constructs will confuse it:
+.br
+     - Any other construct that starts at the left margin and follows the
+above syntax (such as a macro or function call).
+.br
+     - Some macros that tinker with the syntax of the function header.
+.sp
+The --varargs switch is obsolete, and is recognized only for
+backwards compatibility.  The present version of
+.I ansi2knr
+will always attempt to convert a ... argument to va_alist and va_dcl.
+.SH AUTHOR
+L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and
+continues to maintain the current version; most of the code in the current
+version is his work.  ansi2knr also includes contributions by Francois
+Pinard <pinard@iro.umontreal.ca> and Jim Avera <jima@netcom.com>.

+
+		    GHOSTSCRIPT GENERAL PUBLIC LICENSE
+		    (Clarified 11 Feb 1988)
+
+ Copyright (C) 1988 Richard M. Stallman
+ Everyone is permitted to copy and distribute verbatim copies of this
+ license, but changing it is not allowed.  You can also use this wording
+ to make the terms for other programs.
+
+  The license agreements of most software companies keep you at the
+mercy of those companies.  By contrast, our general public license is
+intended to give everyone the right to share Ghostscript.  To make sure
+that you get the rights we want you to have, we need to make
+restrictions that forbid anyone to deny you these rights or to ask you
+to surrender the rights.  Hence this license agreement.
+
+  Specifically, we want to make sure that you have the right to give
+away copies of Ghostscript, that you receive source code or else can get
+it if you want it, that you can change Ghostscript or use pieces of it
+in new free programs, and that you know you can do these things.
+
+  To make sure that everyone has such rights, we have to forbid you to
+deprive anyone else of these rights.  For example, if you distribute
+copies of Ghostscript, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must tell them their rights.
+
+  Also, for our own protection, we must make certain that everyone finds
+out that there is no warranty for Ghostscript.  If Ghostscript is
+modified by someone else and passed on, we want its recipients to know
+that what they have is not what we distributed, so that any problems
+introduced by others will not reflect on our reputation.
+
+  Therefore we (Richard M. Stallman and the Free Software Foundation,
+Inc.) make the following terms which say what you must do to be allowed
+to distribute or change Ghostscript.
+
+
+			COPYING POLICIES
+
+  1. You may copy and distribute verbatim copies of Ghostscript source
+code as you receive it, in any medium, provided that you conspicuously
+and appropriately publish on each copy a valid copyright and license
+notice "Copyright (C) 1989 Aladdin Enterprises.  All rights reserved.
+Distributed by Free Software Foundation, Inc." (or with whatever year is
+appropriate); keep intact the notices on all files that refer to this
+License Agreement and to the absence of any warranty; and give any other
+recipients of the Ghostscript program a copy of this License Agreement
+along with the program.  You may charge a distribution fee for the
+physical act of transferring a copy.
+
+  2. You may modify your copy or copies of Ghostscript or any portion of
+it, and copy and distribute such modifications under the terms of
+Paragraph 1 above, provided that you also do the following:
+
+    a) cause the modified files to carry prominent notices stating
+    that you changed the files and the date of any change; and
+
+    b) cause the whole of any work that you distribute or publish,
+    that in whole or in part contains or is a derivative of Ghostscript
+    or any part thereof, to be licensed at no charge to all third
+    parties on terms identical to those contained in this License
+    Agreement (except that you may choose to grant more extensive
+    warranty protection to some or all third parties, at your option).
+
+    c) You may charge a distribution fee for the physical act of
+    transferring a copy, and you may at your option offer warranty
+    protection in exchange for a fee.
+
+Mere aggregation of another unrelated program with this program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other program under the scope of these terms.
+
+  3. You may copy and distribute Ghostscript (or a portion or derivative
+of it, under Paragraph 2) in object code or executable form under the
+terms of Paragraphs 1 and 2 above provided that you also do one of the
+following:
+
+    a) accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    b) accompany it with a written offer, valid for at least three
+    years, to give any third party free (except for a nominal
+    shipping charge) a complete machine-readable copy of the
+    corresponding source code, to be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    c) accompany it with the information you received as to where the
+    corresponding source code may be obtained.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form alone.)
+
+For an executable file, complete source code means all the source code for
+all modules it contains; but, as a special exception, it need not include
+source code for modules which are standard libraries that accompany the
+operating system on which the executable file runs.
+
+  4. You may not copy, sublicense, distribute or transfer Ghostscript
+except as expressly provided under this License Agreement.  Any attempt
+otherwise to copy, sublicense, distribute or transfer Ghostscript is
+void and your rights to use the program under this License agreement
+shall be automatically terminated.  However, parties who have received
+computer software programs from you with this License Agreement will not
+have their licenses terminated so long as such parties remain in full
+compliance.
+
+  5. If you wish to incorporate parts of Ghostscript into other free
+programs whose distribution conditions are different, write to the Free
+Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not
+yet worked out a simple rule that can be stated here, but we will often
+permit this.  We will be guided by the two goals of preserving the free
+status of all derivatives of our free software and of promoting the
+sharing and reuse of software.
+
+Your comments and suggestions about our licensing policies and our
+software are welcome!  Please contact the Free Software Foundation,
+Inc., 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.

+CHANGE LOG for Independent JPEG Group's JPEG software
+
+
+Version 6b  27-Mar-1998
+-----------------------
+
+jpegtran has new features for lossless image transformations (rotation
+and flipping) as well as "lossless" reduction to grayscale.
+
+jpegtran now copies comments by default; it has a -copy switch to enable
+copying all APPn blocks as well, or to suppress comments.  (Formerly it
+always suppressed comments and APPn blocks.)  jpegtran now also preserves
+JFIF version and resolution information.
+
+New decompressor library feature: COM and APPn markers found in the input
+file can be saved in memory for later use by the application.  (Before,
+you had to code this up yourself with a custom marker processor.)
+
+There is an unused field "void * client_data" now in compress and decompress
+parameter structs; this may be useful in some applications.
+
+JFIF version number information is now saved by the decoder and accepted by
+the encoder.  jpegtran uses this to copy the source file's version number,
+to ensure "jpegtran -copy all" won't create bogus files that contain JFXX
+extensions but claim to be version 1.01.  Applications that generate their
+own JFXX extension markers also (finally) have a supported way to cause the
+encoder to emit JFIF version number 1.02.
+
+djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather
+than as unknown APP0 markers.
+
+In -verbose mode, djpeg and rdjpgcom will try to print the contents of
+APP12 markers as text.  Some digital cameras store useful text information
+in APP12 markers.
+
+Handling of truncated data streams is more robust: blocks beyond the one in
+which the error occurs will be output as uniform gray, or left unchanged
+if decoding a progressive JPEG.  The appearance no longer depends on the
+Huffman tables being used.
+
+Huffman tables are checked for validity much more carefully than before.
+
+To avoid the Unisys LZW patent, djpeg's GIF output capability has been
+changed to produce "uncompressed GIFs", and cjpeg's GIF input capability
+has been removed altogether.  We're not happy about it either, but there
+seems to be no good alternative.
+
+The configure script now supports building libjpeg as a shared library
+on many flavors of Unix (all the ones that GNU libtool knows how to
+build shared libraries for).  Use "./configure --enable-shared" to
+try this out.
+
+New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio.
+Also, a jconfig file and a build script for Metrowerks CodeWarrior
+on Apple Macintosh.  makefile.dj has been updated for DJGPP v2, and there
+are miscellaneous other minor improvements in the makefiles.
+
+jmemmac.c now knows how to create temporary files following Mac System 7
+conventions.
+
+djpeg's -map switch is now able to read raw-format PPM files reliably.
+
+cjpeg -progressive -restart no longer generates any unnecessary DRI markers.
+
+Multiple calls to jpeg_simple_progression for a single JPEG object
+no longer leak memory.
+
+
+Version 6a  7-Feb-96
+--------------------
+
+Library initialization sequence modified to detect version mismatches
+and struct field packing mismatches between library and calling application.
+This change requires applications to be recompiled, but does not require
+any application source code change.
+
+All routine declarations changed to the style "GLOBAL(type) name ...",
+that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the
+routine's return type as an argument.  This makes it possible to add
+Microsoft-style linkage keywords to all the routines by changing just
+these macros.  Note that any application code that was using these macros
+will have to be changed.
+
+DCT coefficient quantization tables are now stored in normal array order
+rather than zigzag order.  Application code that calls jpeg_add_quant_table,
+or otherwise manipulates quantization tables directly, will need to be
+changed.  If you need to make such code work with either older or newer
+versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is
+recommended.
+
+djpeg's trace capability now dumps DQT tables in natural order, not zigzag
+order.  This allows the trace output to be made into a "-qtables" file
+more easily.
+
+New system-dependent memory manager module for use on Apple Macintosh.
+
+Fix bug in cjpeg's -smooth option: last one or two scanlines would be
+duplicates of the prior line unless the image height mod 16 was 1 or 2.
+
+Repair minor problems in VMS, BCC, MC6 makefiles.
+
+New configure script based on latest GNU Autoconf.
+
+Correct the list of include files needed by MetroWerks C for ccommand().
+
+Numerous small documentation updates.
+
+
+Version 6  2-Aug-95
+-------------------
+
+Progressive JPEG support: library can read and write full progressive JPEG
+files.  A "buffered image" mode supports incremental decoding for on-the-fly
+display of progressive images.  Simply recompiling an existing IJG-v5-based
+decoder with v6 should allow it to read progressive files, though of course
+without any special progressive display.
+
+New "jpegtran" application performs lossless transcoding between different
+JPEG formats; primarily, it can be used to convert baseline to progressive
+JPEG and vice versa.  In support of jpegtran, the library now allows lossless
+reading and writing of JPEG files as DCT coefficient arrays.  This ability
+may be of use in other applications.
+
+Notes for programmers:
+* We changed jpeg_start_decompress() to be able to suspend; this makes all
+decoding modes available to suspending-input applications.  However,
+existing applications that use suspending input will need to be changed
+to check the return value from jpeg_start_decompress().  You don't need to
+do anything if you don't use a suspending data source.
+* We changed the interface to the virtual array routines: access_virt_array
+routines now take a count of the number of rows to access this time.  The
+last parameter to request_virt_array routines is now interpreted as the
+maximum number of rows that may be accessed at once, but not necessarily
+the height of every access.
+
+
+Version 5b  15-Mar-95
+---------------------
+
+Correct bugs with grayscale images having v_samp_factor > 1.
+
+jpeg_write_raw_data() now supports output suspension.
+
+Correct bugs in "configure" script for case of compiling in
+a directory other than the one containing the source files.
+
+Repair bug in jquant1.c: sometimes didn't use as many colors as it could.
+
+Borland C makefile and jconfig file work under either MS-DOS or OS/2.
+
+Miscellaneous improvements to documentation.
+
+
+Version 5a  7-Dec-94
+--------------------
+
+Changed color conversion roundoff behavior so that grayscale values are
+represented exactly.  (This causes test image files to change.)
+
+Make ordered dither use 16x16 instead of 4x4 pattern for a small quality
+improvement.
+
+New configure script based on latest GNU Autoconf.
+Fix configure script to handle CFLAGS correctly.
+Rename *.auto files to *.cfg, so that configure script still works if
+file names have been truncated for DOS.
+
+Fix bug in rdbmp.c: didn't allow for extra data between header and image.
+
+Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data.
+
+Fix several bugs in rdrle.c.
+
+NEED_SHORT_EXTERNAL_NAMES option was broken.
+
+Revise jerror.h/jerror.c for more flexibility in message table.
+
+Repair oversight in jmemname.c NO_MKTEMP case: file could be there
+but unreadable.
+
+
+Version 5  24-Sep-94
+--------------------
+
+Version 5 represents a nearly complete redesign and rewrite of the IJG
+software.  Major user-visible changes include:
+  * Automatic configuration simplifies installation for most Unix systems.
+  * A range of speed vs. image quality tradeoffs are supported.
+    This includes resizing of an image during decompression: scaling down
+    by a factor of 1/2, 1/4, or 1/8 is handled very efficiently.
+  * New programs rdjpgcom and wrjpgcom allow insertion and extraction
+    of text comments in a JPEG file.
+
+The application programmer's interface to the library has changed completely.
+Notable improvements include:
+  * We have eliminated the use of callback routines for handling the
+    uncompressed image data.  The application now sees the library as a
+    set of routines that it calls to read or write image data on a
+    scanline-by-scanline basis.
+  * The application image data is represented in a conventional interleaved-
+    pixel format, rather than as a separate array for each color channel.
+    This can save a copying step in many programs.
+  * The handling of compressed data has been cleaned up: the application can
+    supply routines to source or sink the compressed data.  It is possible to
+    suspend processing on source/sink buffer overrun, although this is not
+    supported in all operating modes.
+  * All static state has been eliminated from the library, so that multiple
+    instances of compression or decompression can be active concurrently.
+  * JPEG abbreviated datastream formats are supported, ie, quantization and
+    Huffman tables can be stored separately from the image data.
+  * And not only that, but the documentation of the library has improved
+    considerably!
+
+
+The last widely used release before the version 5 rewrite was version 4A of
+18-Feb-93.  Change logs before that point have been discarded, since they
+are not of much interest after the rewrite.

+.TH CJPEG 1 "20 March 1998"
+.SH NAME
+cjpeg \- compress an image file to a JPEG file
+.SH SYNOPSIS
+.B cjpeg
+[
+.I options
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B cjpeg
+compresses the named image file, or the standard input if no file is
+named, and produces a JPEG/JFIF file on the standard output.
+The currently supported input file formats are: PPM (PBMPLUS color
+format), PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster
+Toolkit format).  (RLE is supported only if the URT library is available.)
+.SH OPTIONS
+All switch names may be abbreviated; for example,
+.B \-grayscale
+may be written
+.B \-gray
+or
+.BR \-gr .
+Most of the "basic" switches can be abbreviated to as little as one letter.
+Upper and lower case are equivalent (thus
+.B \-BMP
+is the same as
+.BR \-bmp ).
+British spellings are also accepted (e.g.,
+.BR \-greyscale ),
+though for brevity these are not mentioned below.
+.PP
+The basic switches are:
+.TP
+.BI \-quality " N"
+Scale quantization tables to adjust image quality.  Quality is 0 (worst) to
+100 (best); default is 75.  (See below for more info.)
+.TP
+.B \-grayscale
+Create monochrome JPEG file from color input.  Be sure to use this switch when
+compressing a grayscale BMP file, because
+.B cjpeg
+isn't bright enough to notice whether a BMP file uses only shades of gray.
+By saying
+.BR \-grayscale ,
+you'll get a smaller JPEG file that takes less time to process.
+.TP
+.B \-optimize
+Perform optimization of entropy encoding parameters.  Without this, default
+encoding parameters are used.
+.B \-optimize
+usually makes the JPEG file a little smaller, but
+.B cjpeg
+runs somewhat slower and needs much more memory.  Image quality and speed of
+decompression are unaffected by
+.BR \-optimize .
+.TP
+.B \-progressive
+Create progressive JPEG file (see below).
+.TP
+.B \-targa
+Input file is Targa format.  Targa files that contain an "identification"
+field will not be automatically recognized by
+.BR cjpeg ;
+for such files you must specify
+.B \-targa
+to make
+.B cjpeg
+treat the input as Targa format.
+For most Targa files, you won't need this switch.
+.PP
+The
+.B \-quality
+switch lets you trade off compressed file size against quality of the
+reconstructed image: the higher the quality setting, the larger the JPEG file,
+and the closer the output image will be to the original input.  Normally you
+want to use the lowest quality setting (smallest file) that decompresses into
+something visually indistinguishable from the original image.  For this
+purpose the quality setting should be between 50 and 95; the default of 75 is
+often about right.  If you see defects at
+.B \-quality
+75, then go up 5 or 10 counts at a time until you are happy with the output
+image.  (The optimal setting will vary from one image to another.)
+.PP
+.B \-quality
+100 will generate a quantization table of all 1's, minimizing loss in the
+quantization step (but there is still information loss in subsampling, as well
+as roundoff error).  This setting is mainly of interest for experimental
+purposes.  Quality values above about 95 are
+.B not
+recommended for normal use; the compressed file size goes up dramatically for
+hardly any gain in output image quality.
+.PP
+In the other direction, quality values below 50 will produce very small files
+of low image quality.  Settings around 5 to 10 might be useful in preparing an
+index of a large image library, for example.  Try
+.B \-quality
+2 (or so) for some amusing Cubist effects.  (Note: quality
+values below about 25 generate 2-byte quantization tables, which are
+considered optional in the JPEG standard.
+.B cjpeg
+emits a warning message when you give such a quality value, because some
+other JPEG programs may be unable to decode the resulting file.  Use
+.B \-baseline
+if you need to ensure compatibility at low quality values.)
+.PP
+The
+.B \-progressive
+switch creates a "progressive JPEG" file.  In this type of JPEG file, the data
+is stored in multiple scans of increasing quality.  If the file is being
+transmitted over a slow communications link, the decoder can use the first
+scan to display a low-quality image very quickly, and can then improve the
+display with each subsequent scan.  The final image is exactly equivalent to a
+standard JPEG file of the same quality setting, and the total file size is
+about the same --- often a little smaller.
+.B Caution:
+progressive JPEG is not yet widely implemented, so many decoders will be
+unable to view a progressive JPEG file at all.
+.PP
+Switches for advanced users:
+.TP
+.B \-dct int
+Use integer DCT method (default).
+.TP
+.B \-dct fast
+Use fast integer DCT (less accurate).
+.TP
+.B \-dct float
+Use floating-point DCT method.
+The float method is very slightly more accurate than the int method, but is
+much slower unless your machine has very fast floating-point hardware.  Also
+note that results of the floating-point method may vary slightly across
+machines, while the integer methods should give the same results everywhere.
+The fast integer method is much less accurate than the other two.
+.TP
+.BI \-restart " N"
+Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
+attached to the number.
+.B \-restart 0
+(the default) means no restart markers.
+.TP
+.BI \-smooth " N"
+Smooth the input image to eliminate dithering noise.  N, ranging from 1 to
+100, indicates the strength of smoothing.  0 (the default) means no smoothing.
+.TP
+.BI \-maxmemory " N"
+Set limit for amount of memory to use in processing large images.  Value is
+in thousands of bytes, or millions of bytes if "M" is attached to the
+number.  For example,
+.B \-max 4m
+selects 4000000 bytes.  If more space is needed, temporary files will be used.
+.TP
+.BI \-outfile " name"
+Send output image to the named file, not to standard output.
+.TP
+.B \-verbose
+Enable debug printout.  More
+.BR \-v 's
+give more output.  Also, version information is printed at startup.
+.TP
+.B \-debug
+Same as
+.BR \-verbose .
+.PP
+The
+.B \-restart
+option inserts extra markers that allow a JPEG decoder to resynchronize after
+a transmission error.  Without restart markers, any damage to a compressed
+file will usually ruin the image from the point of the error to the end of the
+image; with restart markers, the damage is usually confined to the portion of
+the image up to the next restart marker.  Of course, the restart markers
+occupy extra space.  We recommend
+.B \-restart 1
+for images that will be transmitted across unreliable networks such as Usenet.
+.PP
+The
+.B \-smooth
+option filters the input to eliminate fine-scale noise.  This is often useful
+when converting dithered images to JPEG: a moderate smoothing factor of 10 to
+50 gets rid of dithering patterns in the input file, resulting in a smaller
+JPEG file and a better-looking image.  Too large a smoothing factor will
+visibly blur the image, however.
+.PP
+Switches for wizards:
+.TP
+.B \-baseline
+Force baseline-compatible quantization tables to be generated.  This clamps
+quantization values to 8 bits even at low quality settings.  (This switch is
+poorly named, since it does not ensure that the output is actually baseline
+JPEG.  For example, you can use
+.B \-baseline
+and
+.B \-progressive
+together.)
+.TP
+.BI \-qtables " file"
+Use the quantization tables given in the specified text file.
+.TP
+.BI \-qslots " N[,...]"
+Select which quantization table to use for each color component.
+.TP
+.BI \-sample " HxV[,...]"
+Set JPEG sampling factors for each color component.
+.TP
+.BI \-scans " file"
+Use the scan script given in the specified text file.
+.PP
+The "wizard" switches are intended for experimentation with JPEG.  If you
+don't know what you are doing, \fBdon't use them\fR.  These switches are
+documented further in the file wizard.doc.
+.SH EXAMPLES
+.LP
+This example compresses the PPM file foo.ppm with a quality factor of
+60 and saves the output as foo.jpg:
+.IP
+.B cjpeg \-quality
+.I 60 foo.ppm
+.B >
+.I foo.jpg
+.SH HINTS
+Color GIF files are not the ideal input for JPEG; JPEG is really intended for
+compressing full-color (24-bit) images.  In particular, don't try to convert
+cartoons, line drawings, and other images that have only a few distinct
+colors.  GIF works great on these, JPEG does not.  If you want to convert a
+GIF to JPEG, you should experiment with
+.BR cjpeg 's
+.B \-quality
+and
+.B \-smooth
+options to get a satisfactory conversion.
+.B \-smooth 10
+or so is often helpful.
+.PP
+Avoid running an image through a series of JPEG compression/decompression
+cycles.  Image quality loss will accumulate; after ten or so cycles the image
+may be noticeably worse than it was after one cycle.  It's best to use a
+lossless format while manipulating an image, then convert to JPEG format when
+you are ready to file the image away.
+.PP
+The
+.B \-optimize
+option to
+.B cjpeg
+is worth using when you are making a "final" version for posting or archiving.
+It's also a win when you are using low quality settings to make very small
+JPEG files; the percentage improvement is often a lot more than it is on
+larger files.  (At present,
+.B \-optimize
+mode is always selected when generating progressive JPEG files.)
+.SH ENVIRONMENT
+.TP
+.B JPEGMEM
+If this environment variable is set, its value is the default memory limit.
+The value is specified as described for the
+.B \-maxmemory
+switch.
+.B JPEGMEM
+overrides the default value specified when the program was compiled, and
+itself is overridden by an explicit
+.BR \-maxmemory .

+.SH AUTHOR
+Independent JPEG Group
+.SH BUGS
+Arithmetic coding is not supported for legal reasons.
+.PP
+GIF input files are no longer supported, to avoid the Unisys LZW patent.
+Use a Unisys-licensed program if you need to read a GIF file.  (Conversion
+of GIF files to JPEG is usually a bad idea anyway.)
+.PP
+Not all variants of BMP and Targa file formats are supported.
+.PP
+The
+.B \-targa
+switch is not a bug, it's a feature.  (It would be a bug if the Targa format
+designers had not been clueless.)
+.PP
+Still not as fast as we'd like.

+IJG JPEG LIBRARY:  CODING RULES
+
+Copyright (C) 1991-1996, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+Since numerous people will be contributing code and bug fixes, it's important
+to establish a common coding style.  The goal of using similar coding styles
+is much more important than the details of just what that style is.
+
+In general we follow the recommendations of "Recommended C Style and Coding
+Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
+Brader).  This document is available in the IJG FTP archive (see
+jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).
+
+Block comments should be laid out thusly:
+
+/*
+ *  Block comments in this style.
+ */
+
+We indent statements in K&R style, e.g.,
+	if (test) {
+	  then-part;
+	} else {
+	  else-part;
+	}
+with two spaces per indentation level.  (This indentation convention is
+handled automatically by GNU Emacs and many other text editors.)
+
+Multi-word names should be written in lower case with underscores, e.g.,
+multi_word_name (not multiWordName).  Preprocessor symbols and enum constants
+are similar but upper case (MULTI_WORD_NAME).  Names should be unique within
+the first fifteen characters.  (On some older systems, global names must be
+unique within six characters.  We accommodate this without cluttering the
+source code by using macros to substitute shorter names.)
+
+We use function prototypes everywhere; we rely on automatic source code
+transformation to feed prototype-less C compilers.  Transformation is done
+by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
+ansi2knr is not very bright, so it imposes a format requirement on function
+declarations: the function name MUST BEGIN IN COLUMN 1.  Thus all functions
+should be written in the following style:
+
+LOCAL(int *)
+function_name (int a, char *b)
+{
+    code...
+}
+
+Note that each function definition must begin with GLOBAL(type), LOCAL(type),
+or METHODDEF(type).  These macros expand to "static type" or just "type" as
+appropriate.  They provide a readable indication of the routine's usage and
+can readily be changed for special needs.  (For instance, special linkage
+keywords can be inserted for use in Windows DLLs.)
+
+ansi2knr does not transform method declarations (function pointers in
+structs).  We handle these with a macro JMETHOD, defined as
+	#ifdef HAVE_PROTOTYPES
+	#define JMETHOD(type,methodname,arglist)  type (*methodname) arglist
+	#else
+	#define JMETHOD(type,methodname,arglist)  type (*methodname) ()
+	#endif
+which is used like this:
+	struct function_pointers {
+	  JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));
+	  JMETHOD(void, term_entropy_encoder, (void));
+	};
+Note the set of parentheses surrounding the parameter list.
+
+A similar solution is used for forward and external function declarations
+(see the EXTERN and JPP macros).
+
+If the code is to work on non-ANSI compilers, we cannot rely on a prototype
+declaration to coerce actual parameters into the right types.  Therefore, use
+explicit casts on actual parameters whenever the actual parameter type is not
+identical to the formal parameter.  Beware of implicit conversions to "int".
+
+It seems there are some non-ANSI compilers in which the sizeof() operator
+is defined to return int, yet size_t is defined as long.  Needless to say,
+this is brain-damaged.  Always use the SIZEOF() macro in place of sizeof(),
+so that the result is guaranteed to be of type size_t.
+
+
+The JPEG library is intended to be used within larger programs.  Furthermore,
+we want it to be reentrant so that it can be used by applications that process
+multiple images concurrently.  The following rules support these requirements:
+
+1. Avoid direct use of file I/O, "malloc", error report printouts, etc;
+pass these through the common routines provided.
+
+2. Minimize global namespace pollution.  Functions should be declared static
+wherever possible.  (Note that our method-based calling conventions help this
+a lot: in many modules only the initialization function will ever need to be
+called directly, so only that function need be externally visible.)  All
+global function names should begin with "jpeg_", and should have an
+abbreviated name (unique in the first six characters) substituted by macro
+when NEED_SHORT_EXTERNAL_NAMES is set.
+
+3. Don't use global variables; anything that must be used in another module
+should be in the common data structures.
+
+4. Don't use static variables except for read-only constant tables.  Variables
+that should be private to a module can be placed into private structures (see
+the system architecture document, structure.doc).
+
+5. Source file names should begin with "j" for files that are part of the
+library proper; source files that are not part of the library, such as cjpeg.c
+and djpeg.c, do not begin with "j".  Keep source file names to eight
+characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers.  Keep
+compression and decompression code in separate source files --- some
+applications may want only one half of the library.
+
+Note: these rules (particularly #4) are not followed religiously in the
+modules that are used in cjpeg/djpeg but are not part of the JPEG library
+proper.  Those modules are not really intended to be used in other
+applications.

+.TH DJPEG 1 "22 August 1997"
+.SH NAME
+djpeg \- decompress a JPEG file to an image file
+.SH SYNOPSIS
+.B djpeg
+[
+.I options
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B djpeg
+decompresses the named JPEG file, or the standard input if no file is named,
+and produces an image file on the standard output.  PBMPLUS (PPM/PGM), BMP,
+GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected.
+(RLE is supported only if the URT library is available.)
+.SH OPTIONS
+All switch names may be abbreviated; for example,
+.B \-grayscale
+may be written
+.B \-gray
+or
+.BR \-gr .
+Most of the "basic" switches can be abbreviated to as little as one letter.
+Upper and lower case are equivalent (thus
+.B \-BMP
+is the same as
+.BR \-bmp ).
+British spellings are also accepted (e.g.,
+.BR \-greyscale ),
+though for brevity these are not mentioned below.
+.PP
+The basic switches are:
+.TP
+.BI \-colors " N"
+Reduce image to at most N colors.  This reduces the number of colors used in
+the output image, so that it can be displayed on a colormapped display or
+stored in a colormapped file format.  For example, if you have an 8-bit
+display, you'd need to reduce to 256 or fewer colors.
+.TP
+.BI \-quantize " N"
+Same as
+.BR \-colors .
+.B \-colors
+is the recommended name,
+.B \-quantize
+is provided only for backwards compatibility.
+.TP
+.B \-fast
+Select recommended processing options for fast, low quality output.  (The
+default options are chosen for highest quality output.)  Currently, this is
+equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR.
+.TP
+.B \-grayscale
+Force gray-scale output even if JPEG file is color.  Useful for viewing on
+monochrome displays; also,
+.B djpeg
+runs noticeably faster in this mode.
+.TP
+.BI \-scale " M/N"
+Scale the output image by a factor M/N.  Currently the scale factor must be
+1/1, 1/2, 1/4, or 1/8.  Scaling is handy if the image is larger than your
+screen; also,
+.B djpeg
+runs much faster when scaling down the output.
+.TP
+.B \-bmp
+Select BMP output format (Windows flavor).  8-bit colormapped format is
+emitted if
+.B \-colors
+or
+.B \-grayscale
+is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color
+format is emitted.
+.TP
+.B \-gif
+Select GIF output format.  Since GIF does not support more than 256 colors,
+.B \-colors 256
+is assumed (unless you specify a smaller number of colors).
+.TP
+.B \-os2
+Select BMP output format (OS/2 1.x flavor).  8-bit colormapped format is
+emitted if
+.B \-colors
+or
+.B \-grayscale
+is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color
+format is emitted.
+.TP
+.B \-pnm
+Select PBMPLUS (PPM/PGM) output format (this is the default format).
+PGM is emitted if the JPEG file is gray-scale or if
+.B \-grayscale
+is specified; otherwise PPM is emitted.
+.TP
+.B \-rle
+Select RLE output format.  (Requires URT library.)
+.TP
+.B \-targa
+Select Targa output format.  Gray-scale format is emitted if the JPEG file is
+gray-scale or if
+.B \-grayscale
+is specified; otherwise, colormapped format is emitted if
+.B \-colors
+is specified; otherwise, 24-bit full-color format is emitted.
+.PP
+Switches for advanced users:
+.TP
+.B \-dct int
+Use integer DCT method (default).
+.TP
+.B \-dct fast
+Use fast integer DCT (less accurate).
+.TP
+.B \-dct float
+Use floating-point DCT method.
+The float method is very slightly more accurate than the int method, but is
+much slower unless your machine has very fast floating-point hardware.  Also
+note that results of the floating-point method may vary slightly across
+machines, while the integer methods should give the same results everywhere.
+The fast integer method is much less accurate than the other two.
+.TP
+.B \-dither fs
+Use Floyd-Steinberg dithering in color quantization.
+.TP
+.B \-dither ordered
+Use ordered dithering in color quantization.
+.TP
+.B \-dither none
+Do not use dithering in color quantization.
+By default, Floyd-Steinberg dithering is applied when quantizing colors; this
+is slow but usually produces the best results.  Ordered dither is a compromise
+between speed and quality; no dithering is fast but usually looks awful.  Note
+that these switches have no effect unless color quantization is being done.
+Ordered dither is only available in
+.B \-onepass
+mode.
+.TP
+.BI \-map " file"
+Quantize to the colors used in the specified image file.  This is useful for
+producing multiple files with identical color maps, or for forcing a
+predefined set of colors to be used.  The
+.I file
+must be a GIF or PPM file. This option overrides
+.B \-colors
+and
+.BR \-onepass .
+.TP
+.B \-nosmooth
+Use a faster, lower-quality upsampling routine.
+.TP
+.B \-onepass
+Use one-pass instead of two-pass color quantization.  The one-pass method is
+faster and needs less memory, but it produces a lower-quality image.
+.B \-onepass
+is ignored unless you also say
+.B \-colors
+.IR N .
+Also, the one-pass method is always used for gray-scale output (the two-pass
+method is no improvement then).
+.TP
+.BI \-maxmemory " N"
+Set limit for amount of memory to use in processing large images.  Value is
+in thousands of bytes, or millions of bytes if "M" is attached to the
+number.  For example,
+.B \-max 4m
+selects 4000000 bytes.  If more space is needed, temporary files will be used.
+.TP
+.BI \-outfile " name"
+Send output image to the named file, not to standard output.
+.TP
+.B \-verbose
+Enable debug printout.  More
+.BR \-v 's
+give more output.  Also, version information is printed at startup.
+.TP
+.B \-debug
+Same as
+.BR \-verbose .
+.SH EXAMPLES
+.LP
+This example decompresses the JPEG file foo.jpg, quantizes it to
+256 colors, and saves the output in 8-bit BMP format in foo.bmp:
+.IP
+.B djpeg \-colors 256 \-bmp
+.I foo.jpg
+.B >
+.I foo.bmp
+.SH HINTS
+To get a quick preview of an image, use the
+.B \-grayscale
+and/or
+.B \-scale
+switches.
+.B \-grayscale \-scale 1/8
+is the fastest case.
+.PP
+Several options are available that trade off image quality to gain speed.
+.B \-fast
+turns on the recommended settings.
+.PP
+.B \-dct fast
+and/or
+.B \-nosmooth
+gain speed at a small sacrifice in quality.
+When producing a color-quantized image,
+.B \-onepass \-dither ordered
+is fast but much lower quality than the default behavior.
+.B \-dither none
+may give acceptable results in two-pass mode, but is seldom tolerable in
+one-pass mode.
+.PP
+If you are fortunate enough to have very fast floating point hardware,
+\fB\-dct float\fR may be even faster than \fB\-dct fast\fR.  But on most
+machines \fB\-dct float\fR is slower than \fB\-dct int\fR; in this case it is
+not worth using, because its theoretical accuracy advantage is too small to be
+significant in practice.
+.SH ENVIRONMENT
+.TP
+.B JPEGMEM
+If this environment variable is set, its value is the default memory limit.
+The value is specified as described for the
+.B \-maxmemory
+switch.
+.B JPEGMEM
+overrides the default value specified when the program was compiled, and
+itself is overridden by an explicit
+.BR \-maxmemory .

+.SH AUTHOR
+Independent JPEG Group
+.SH BUGS
+Arithmetic coding is not supported for legal reasons.
+.PP
+To avoid the Unisys LZW patent,
+.B djpeg
+produces uncompressed GIF files.  These are larger than they should be, but
+are readable by standard GIF decoders.
+.PP
+Still not as fast as we'd like.

+ *
+ * This file contains a command-line user interface for the JPEG decompressor.
+ * It should work on any system with Unix- or MS-DOS-style command lines.
+ *
+ * Two different command line styles are permitted, depending on the
+ * compile-time switch TWO_FILE_COMMANDLINE:
+ *	djpeg [options]  inputfile outputfile
+ *	djpeg [options]  [inputfile]
+ * In the second style, output is always to standard output, which you'd
+ * normally redirect to a file or pipe to some other program.  Input is
+ * either from a named file or from standard input (typically redirected).
+ * The second style is convenient on Unix but is unhelpful on systems that
+ * don't support pipes.  Also, you MUST use the first style if your system
+ * doesn't do binary I/O to stdin/stdout.
+ * To simplify script writing, the "-outfile" switch is provided.  The syntax
+ *	djpeg [options]  -outfile outputfile  inputfile
+ * works regardless of which command line style is used.

+ * On some systems you may need to set up a signal handler to ensure that
+ * temporary files are deleted if the program is interrupted.  See libjpeg.doc.

+ * Scanlines MUST be supplied in top-to-bottom order if you want your JPEG
+ * files to be compatible with everyone else's.  If you cannot readily read

+IJG JPEG LIBRARY:  FILE LIST
+
+Copyright (C) 1994-1998, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+Here is a road map to the files in the IJG JPEG distribution.  The
+distribution includes the JPEG library proper, plus two application
+programs ("cjpeg" and "djpeg") which use the library to convert JPEG
+files to and from some other popular image formats.  A third application
+"jpegtran" uses the library to do lossless conversion between different
+variants of JPEG.  There are also two stand-alone applications,
+"rdjpgcom" and "wrjpgcom".
+
+
+THE JPEG LIBRARY
+================
+
+Include files:
+
+jpeglib.h	JPEG library's exported data and function declarations.
+jconfig.h	Configuration declarations.  Note: this file is not present
+		in the distribution; it is generated during installation.
+jmorecfg.h	Additional configuration declarations; need not be changed
+		for a standard installation.
+jerror.h	Declares JPEG library's error and trace message codes.
+jinclude.h	Central include file used by all IJG .c files to reference
+		system include files.
+jpegint.h	JPEG library's internal data structures.
+jchuff.h	Private declarations for Huffman encoder modules.
+jdhuff.h	Private declarations for Huffman decoder modules.
+jdct.h		Private declarations for forward & reverse DCT subsystems.
+jmemsys.h	Private declarations for memory management subsystem.
+jversion.h	Version information.
+
+Applications using the library should include jpeglib.h (which in turn
+includes jconfig.h and jmorecfg.h).  Optionally, jerror.h may be included
+if the application needs to reference individual JPEG error codes.  The
+other include files are intended for internal use and would not normally
+be included by an application program.  (cjpeg/djpeg/etc do use jinclude.h,
+since its function is to improve portability of the whole IJG distribution.
+Most other applications will directly include the system include files they
+want, and hence won't need jinclude.h.)
+
+
+C source code files:
+
+These files contain most of the functions intended to be called directly by
+an application program:
+
+jcapimin.c	Application program interface: core routines for compression.
+jcapistd.c	Application program interface: standard compression.
+jdapimin.c	Application program interface: core routines for decompression.
+jdapistd.c	Application program interface: standard decompression.
+jcomapi.c	Application program interface routines common to compression
+		and decompression.
+jcparam.c	Compression parameter setting helper routines.
+jctrans.c	API and library routines for transcoding compression.
+jdtrans.c	API and library routines for transcoding decompression.
+
+Compression side of the library:
+
+jcinit.c	Initialization: determines which other modules to use.
+jcmaster.c	Master control: setup and inter-pass sequencing logic.
+jcmainct.c	Main buffer controller (preprocessor => JPEG compressor).
+jcprepct.c	Preprocessor buffer controller.
+jccoefct.c	Buffer controller for DCT coefficient buffer.
+jccolor.c	Color space conversion.
+jcsample.c	Downsampling.
+jcdctmgr.c	DCT manager (DCT implementation selection & control).
+jfdctint.c	Forward DCT using slow-but-accurate integer method.
+jfdctfst.c	Forward DCT using faster, less accurate integer method.
+jfdctflt.c	Forward DCT using floating-point arithmetic.
+jchuff.c	Huffman entropy coding for sequential JPEG.
+jcphuff.c	Huffman entropy coding for progressive JPEG.
+jcmarker.c	JPEG marker writing.
+jdatadst.c	Data destination manager for stdio output.
+
+Decompression side of the library:
+
+jdmaster.c	Master control: determines which other modules to use.
+jdinput.c	Input controller: controls input processing modules.
+jdmainct.c	Main buffer controller (JPEG decompressor => postprocessor).
+jdcoefct.c	Buffer controller for DCT coefficient buffer.
+jdpostct.c	Postprocessor buffer controller.
+jdmarker.c	JPEG marker reading.
+jdhuff.c	Huffman entropy decoding for sequential JPEG.
+jdphuff.c	Huffman entropy decoding for progressive JPEG.
+jddctmgr.c	IDCT manager (IDCT implementation selection & control).
+jidctint.c	Inverse DCT using slow-but-accurate integer method.
+jidctfst.c	Inverse DCT using faster, less accurate integer method.
+jidctflt.c	Inverse DCT using floating-point arithmetic.
+jidctred.c	Inverse DCTs with reduced-size outputs.
+jdsample.c	Upsampling.
+jdcolor.c	Color space conversion.
+jdmerge.c	Merged upsampling/color conversion (faster, lower quality).
+jquant1.c	One-pass color quantization using a fixed-spacing colormap.
+jquant2.c	Two-pass color quantization using a custom-generated colormap.
+		Also handles one-pass quantization to an externally given map.
+jdatasrc.c	Data source manager for stdio input.
+
+Support files for both compression and decompression:
+
+jerror.c	Standard error handling routines (application replaceable).
+jmemmgr.c	System-independent (more or less) memory management code.
+jutils.c	Miscellaneous utility routines.
+
+jmemmgr.c relies on a system-dependent memory management module.  The IJG
+distribution includes the following implementations of the system-dependent
+module:
+
+jmemnobs.c	"No backing store": assumes adequate virtual memory exists.
+jmemansi.c	Makes temporary files with ANSI-standard routine tmpfile().
+jmemname.c	Makes temporary files with program-generated file names.
+jmemdos.c	Custom implementation for MS-DOS (16-bit environment only):
+		can use extended and expanded memory as well as temp files.
+jmemmac.c	Custom implementation for Apple Macintosh.
+
+Exactly one of the system-dependent modules should be configured into an
+installed JPEG library (see install.doc for hints about which one to use).
+On unusual systems you may find it worthwhile to make a special
+system-dependent memory manager.
+
+
+Non-C source code files:
+
+jmemdosa.asm	80x86 assembly code support for jmemdos.c; used only in
+		MS-DOS-specific configurations of the JPEG library.
+
+
+CJPEG/DJPEG/JPEGTRAN
+====================
+
+Include files:
+
+cdjpeg.h	Declarations shared by cjpeg/djpeg/jpegtran modules.
+cderror.h	Additional error and trace message codes for cjpeg et al.
+transupp.h	Declarations for jpegtran support routines in transupp.c.
+
+C source code files:
+
+cjpeg.c		Main program for cjpeg.
+djpeg.c		Main program for djpeg.
+jpegtran.c	Main program for jpegtran.
+cdjpeg.c	Utility routines used by all three programs.
+rdcolmap.c	Code to read a colormap file for djpeg's "-map" switch.
+rdswitch.c	Code to process some of cjpeg's more complex switches.
+		Also used by jpegtran.
+transupp.c	Support code for jpegtran: lossless image manipulations.
+
+Image file reader modules for cjpeg:
+
+rdbmp.c		BMP file input.
+rdgif.c		GIF file input (now just a stub).
+rdppm.c		PPM/PGM file input.
+rdrle.c		Utah RLE file input.
+rdtarga.c	Targa file input.
+
+Image file writer modules for djpeg:
+
+wrbmp.c		BMP file output.
+wrgif.c		GIF file output (a mere shadow of its former self).
+wrppm.c		PPM/PGM file output.
+wrrle.c		Utah RLE file output.
+wrtarga.c	Targa file output.
+
+
+RDJPGCOM/WRJPGCOM
+=================
+
+C source code files:
+
+rdjpgcom.c	Stand-alone rdjpgcom application.
+wrjpgcom.c	Stand-alone wrjpgcom application.
+
+These programs do not depend on the IJG library.  They do use
+jconfig.h and jinclude.h, only to improve portability.
+
+
+ADDITIONAL FILES
+================
+
+Documentation (see README for a guide to the documentation files):
+
+README		Master documentation file.
+*.doc		Other documentation files.
+*.1		Documentation in Unix man page format.

+INSTALLATION INSTRUCTIONS for the Independent JPEG Group's JPEG software
+
+Copyright (C) 1991-1998, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+This file explains how to configure and install the IJG software.  We have
+tried to make this software extremely portable and flexible, so that it can be
+adapted to almost any environment.  The downside of this decision is that the
+installation process is complicated.  We have provided shortcuts to simplify
+the task on common systems.  But in any case, you will need at least a little
+familiarity with C programming and program build procedures for your system.
+
+If you are only using this software as part of a larger program, the larger
+program's installation procedure may take care of configuring the IJG code.
+For example, Ghostscript's installation script will configure the IJG code.
+You don't need to read this file if you just want to compile Ghostscript.
+
+If you are on a Unix machine, you may not need to read this file at all.
+Try doing
+	./configure
+	make
+	make test
+If that doesn't complain, do
+	make install
+(better do "make -n install" first to see if the makefile will put the files
+where you want them).  Read further if you run into snags or want to customize
+the code for your system.
+
+
+TABLE OF CONTENTS
+-----------------
+
+Before you start
+Configuring the software:
+	using the automatic "configure" script
+	using one of the supplied jconfig and makefile files
+	by hand
+Building the software
+Testing the software
+Installing the software
+Optional stuff
+Optimization
+Hints for specific systems
+
+
+BEFORE YOU START
+================
+
+Before installing the software you must unpack the distributed source code.
+Since you are reading this file, you have probably already succeeded in this
+task.  However, there is a potential for error if you needed to convert the
+files to the local standard text file format (for example, if you are on
+MS-DOS you may have converted LF end-of-line to CR/LF).  You must apply
+such conversion to all the files EXCEPT those whose names begin with "test".
+The test files contain binary data; if you change them in any way then the
+self-test will give bad results.
+
+Please check the last section of this file to see if there are hints for the
+specific machine or compiler you are using.
+
+
+CONFIGURING THE SOFTWARE
+========================
+
+To configure the IJG code for your system, you need to create two files:
+  * jconfig.h: contains values for system-dependent #define symbols.
+  * Makefile: controls the compilation process.
+(On a non-Unix machine, you may create "project files" or some other
+substitute for a Makefile.  jconfig.h is needed in any environment.)
+
+We provide three different ways to generate these files:
+  * On a Unix system, you can just run the "configure" script.
+  * We provide sample jconfig files and makefiles for popular machines;
+    if your machine matches one of the samples, just copy the right sample
+    files to jconfig.h and Makefile.
+  * If all else fails, read the instructions below and make your own files.
+
+
+Configuring the software using the automatic "configure" script
+---------------------------------------------------------------
+
+If you are on a Unix machine, you can just type
+	./configure
+and let the configure script construct appropriate configuration files.
+If you're using "csh" on an old version of System V, you might need to type
+	sh configure
+instead to prevent csh from trying to execute configure itself.
+Expect configure to run for a few minutes, particularly on slower machines;
+it works by compiling a series of test programs.
+
+Configure was created with GNU Autoconf and it follows the usual conventions
+for GNU configure scripts.  It makes a few assumptions that you may want to
+override.  You can do this by providing optional switches to configure:
+
+* If you want to build libjpeg as a shared library, say
+	./configure --enable-shared
+To get both shared and static libraries, say
+	./configure --enable-shared --enable-static
+Note that these switches invoke GNU libtool to take care of system-dependent
+shared library building methods.  If things don't work this way, please try
+running configure without either switch; that should build a static library
+without using libtool.  If that works, your problem is probably with libtool
+not with the IJG code.  libtool is fairly new and doesn't support all flavors
+of Unix yet.  (You might be able to find a newer version of libtool than the
+one included with libjpeg; see ftp.gnu.org.  Report libtool problems to
+bug-libtool@gnu.org.)
+
+* Configure will use gcc (GNU C compiler) if it's available, otherwise cc.
+To force a particular compiler to be selected, use the CC option, for example
+	./configure CC='cc'
+The same method can be used to include any unusual compiler switches.
+For example, on HP-UX you probably want to say
+	./configure CC='cc -Aa'
+to get HP's compiler to run in ANSI mode.
+
+* The default CFLAGS setting is "-O" for non-gcc compilers, "-O2" for gcc.
+You can override this by saying, for example,
+	./configure CFLAGS='-g'
+if you want to compile with debugging support.
+
+* Configure will set up the makefile so that "make install" will install files
+into /usr/local/bin, /usr/local/man, etc.  You can specify an installation
+prefix other than "/usr/local" by giving configure the option "--prefix=PATH".
+
+* If you don't have a lot of swap space, you may need to enable the IJG
+software's internal virtual memory mechanism.  To do this, give the option
+"--enable-maxmem=N" where N is the default maxmemory limit in megabytes.
+This is discussed in more detail under "Selecting a memory manager", below.
+You probably don't need to worry about this on reasonably-sized Unix machines,
+unless you plan to process very large images.
+
+Configure has some other features that are useful if you are cross-compiling
+or working in a network of multiple machine types; but if you need those
+features, you probably already know how to use them.
+
+
+Configuring the software using one of the supplied jconfig and makefile files
+-----------------------------------------------------------------------------
+
+If you have one of these systems, you can just use the provided configuration
+files:
+
+Makefile	jconfig file	System and/or compiler
+
+makefile.manx	jconfig.manx	Amiga, Manx Aztec C
+makefile.sas	jconfig.sas	Amiga, SAS C
+makeproj.mac	jconfig.mac	Apple Macintosh, Metrowerks CodeWarrior
+mak*jpeg.st	jconfig.st	Atari ST/STE/TT, Pure C or Turbo C
+makefile.bcc	jconfig.bcc	MS-DOS or OS/2, Borland C
+makefile.dj	jconfig.dj	MS-DOS, DJGPP (Delorie's port of GNU C)
+makefile.mc6	jconfig.mc6	MS-DOS, Microsoft C (16-bit only)
+makefile.wat	jconfig.wat	MS-DOS, OS/2, or Windows NT, Watcom C
+makefile.vc	jconfig.vc	Windows NT/95, MS Visual C++
+make*.ds	jconfig.vc	Windows NT/95, MS Developer Studio
+makefile.mms	jconfig.vms	Digital VMS, with MMS software
+makefile.vms	jconfig.vms	Digital VMS, without MMS software
+
+Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or
+whatever your system uses as the standard makefile name).  For more info see
+the appropriate system-specific hints section near the end of this file.
+
+
+Configuring the software by hand
+--------------------------------
+
+First, generate a jconfig.h file.  If you are moderately familiar with C,
+the comments in jconfig.doc should be enough information to do this; just
+copy jconfig.doc to jconfig.h and edit it appropriately.  Otherwise, you may
+prefer to use the ckconfig.c program.  You will need to compile and execute
+ckconfig.c by hand --- we hope you know at least enough to do that.
+ckconfig.c may not compile the first try (in fact, the whole idea is for it
+to fail if anything is going to).  If you get compile errors, fix them by
+editing ckconfig.c according to the directions given in ckconfig.c.  Once
+you get it to run, it will write a suitable jconfig.h file, and will also
+print out some advice about which makefile to use.
+
+You may also want to look at the canned jconfig files, if there is one for a
+system similar to yours.
+
+Second, select a makefile and copy it to Makefile (or whatever your system
+uses as the standard makefile name).  The most generic makefiles we provide
+are
+	makefile.ansi:	if your C compiler supports function prototypes
+	makefile.unix:	if not.
+(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES"
+in jconfig.h.)  You may want to start from one of the other makefiles if
+there is one for a system similar to yours.
+
+Look over the selected Makefile and adjust options as needed.  In particular
+you may want to change the CC and CFLAGS definitions.  For instance, if you
+are using GCC, set CC=gcc.  If you had to use any compiler switches to get
+ckconfig.c to work, make sure the same switches are in CFLAGS.
+
+If you are on a system that doesn't use makefiles, you'll need to set up
+project files (or whatever you do use) to compile all the source files and
+link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom.
+See the file lists in any of the makefiles to find out which files go into
+each program.  Note that the provided makefiles all make a "library" file
+libjpeg first, but you don't have to do that if you don't want to; the file
+lists identify which source files are actually needed for compression,
+decompression, or both.  As a last resort, you can make a batch script that
+just compiles everything and links it all together; makefile.vms is an example
+of this (it's for VMS systems that have no make-like utility).
+
+Here are comments about some specific configuration decisions you'll
+need to make:
+
+Command line style
+------------------
+
+These programs can use a Unix-like command line style which supports
+redirection and piping, like this:
+	cjpeg inputfile >outputfile
+	cjpeg <inputfile >outputfile
+	source program | cjpeg >outputfile
+The simpler "two file" command line style is just
+	cjpeg inputfile outputfile
+You may prefer the two-file style, particularly if you don't have pipes.
+
+You MUST use two-file style on any system that doesn't cope well with binary
+data fed through stdin/stdout; this is true for some MS-DOS compilers, for
+example.  If you're not on a Unix system, it's safest to assume you need
+two-file style.  (But if your compiler provides either the Posix-standard
+fdopen() library routine or a Microsoft-compatible setmode() routine, you
+can safely use the Unix command line style, by defining USE_FDOPEN or
+USE_SETMODE respectively.)
+
+To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE".
+
+Selecting a memory manager
+--------------------------
+
+The IJG code is capable of working on images that are too big to fit in main
+memory; data is swapped out to temporary files as necessary.  However, the
+code to do this is rather system-dependent.  We provide five different
+memory managers:
+
+* jmemansi.c	This version uses the ANSI-standard library routine tmpfile(),
+		which not all non-ANSI systems have.  On some systems
+		tmpfile() may put the temporary file in a non-optimal
+		location; if you don't like what it does, use jmemname.c.
+
+* jmemname.c	This version creates named temporary files.  For anything
+		except a Unix machine, you'll need to configure the
+		select_file_name() routine appropriately; see the comments
+		near the head of jmemname.c.  If you use this version, define
+		NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files
+		are removed if the program is aborted.
+
+* jmemnobs.c	(That stands for No Backing Store :-).)  This will compile on
+		almost any system, but it assumes you have enough main memory
+		or virtual memory to hold the biggest images you work with.
+
+* jmemdos.c	This should be used with most 16-bit MS-DOS compilers.
+		See the system-specific notes about MS-DOS for more info.
+		IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in
+		jconfig.h, and include the assembly file jmemdosa.asm in the
+		programs.  The supplied makefiles and jconfig files for
+		16-bit MS-DOS compilers already do both.
+
+* jmemmac.c	Custom version for Apple Macintosh; see the system-specific
+		notes for Macintosh for more info.
+
+To use a particular memory manager, change the SYSDEPMEM variable in your
+makefile to equal the corresponding object file name (for example, jmemansi.o
+or jmemansi.obj for jmemansi.c).
+
+If you have plenty of (real or virtual) main memory, just use jmemnobs.c.
+"Plenty" means about ten bytes for every pixel in the largest images
+you plan to process, so a lot of systems don't meet this criterion.
+If yours doesn't, try jmemansi.c first.  If that doesn't compile, you'll have
+to use jmemname.c; be sure to adjust select_file_name() for local conditions.
+You may also need to change unlink() to remove() in close_backing_store().
+
+Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM
+setting to a reasonable value for your system (either by adding a #define for
+DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile).
+This value limits the amount of data space the program will attempt to
+allocate.  Code and static data space isn't counted, so the actual memory
+needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory
+setting.  Larger max-memory settings reduce the amount of I/O needed to
+process a large image, but too large a value can result in "insufficient
+memory" failures.  On most Unix machines (and other systems with virtual
+memory), just set DEFAULT_MAX_MEM to several million and forget it.  At the
+other end of the spectrum, for MS-DOS machines you probably can't go much
+above 300K to 400K.  (On MS-DOS the value refers to conventional memory only.
+Extended/expanded memory is handled separately by jmemdos.c.)
+
+
+BUILDING THE SOFTWARE
+=====================
+
+Now you should be able to compile the software.  Just say "make" (or
+whatever's necessary to start the compilation).  Have a cup of coffee.
+
+Here are some things that could go wrong:
+
+If your compiler complains about undefined structures, you should be able to
+shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h.
+
+If you have trouble with missing system include files or inclusion of the
+wrong ones, read jinclude.h.  This shouldn't happen if you used configure
+or ckconfig.c to set up jconfig.h.
+
+There are a fair number of routines that do not use all of their parameters;
+some compilers will issue warnings about this, which you can ignore.  There
+are also a few configuration checks that may give "unreachable code" warnings.
+Any other warning deserves investigation.
+
+If you don't have a getenv() library routine, define NO_GETENV.
+
+Also see the system-specific hints, below.
+
+
+TESTING THE SOFTWARE
+====================
+
+As a quick test of functionality we've included a small sample image in
+several forms:
+	testorig.jpg	Starting point for the djpeg tests.
+	testimg.ppm	The output of djpeg testorig.jpg
+	testimg.bmp	The output of djpeg -bmp -colors 256 testorig.jpg
+	testimg.jpg	The output of cjpeg testimg.ppm
+	testprog.jpg	Progressive-mode equivalent of testorig.jpg.
+	testimgp.jpg	The output of cjpeg -progressive -optimize testimg.ppm
+(The first- and second-generation .jpg files aren't identical since JPEG is
+lossy.)  If you can generate duplicates of the testimg* files then you
+probably have working programs.
+
+With most of the makefiles, "make test" will perform the necessary
+comparisons.
+
+If you're using a makefile that doesn't provide the test option, run djpeg
+and cjpeg by hand and compare the output files to testimg* with whatever
+binary file comparison tool you have.  The files should be bit-for-bit
+identical.
+
+If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you
+need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t.
+Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h.  A less likely
+configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE
+as long should take care of that one.
+
+If the cjpeg test run fails with "Missing Huffman code table entry", it's a
+good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED.  Go back to the
+configuration step and run ckconfig.c.  (This is a good plan for any other
+test failure, too.)
+
+If you are using Unix (one-file) command line style on a non-Unix system,
+it's a good idea to check that binary I/O through stdin/stdout actually
+works.  You should get the same results from "djpeg <testorig.jpg >out.ppm"
+as from "djpeg -outfile out.ppm testorig.jpg".  Note that the makefiles all
+use the latter style and therefore do not exercise stdin/stdout!  If this
+check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined.
+If it still doesn't work, better use two-file style.
+
+If you chose a memory manager other than jmemnobs.c, you should test that
+temporary-file usage works.  Try "djpeg -bmp -colors 256 -max 0 testorig.jpg"
+and make sure its output matches testimg.bmp.  If you have any really large
+images handy, try compressing them with -optimize and/or decompressing with
+-colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large.
+
+NOTE: this is far from an exhaustive test of the JPEG software; some modules,
+such as 1-pass color quantization, are not exercised at all.  It's just a
+quick test to give you some confidence that you haven't missed something
+major.
+
+
+INSTALLING THE SOFTWARE
+=======================
+
+Once you're done with the above steps, you can install the software by
+copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom)
+to wherever you normally install programs.  On Unix systems, you'll also want
+to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1)
+in the man-page directory.  The pre-fab makefiles don't support this step
+since there's such a wide variety of installation procedures on different
+systems.
+
+If you generated a Makefile with the "configure" script, you can just say
+	make install
+to install the programs and their man pages into the standard places.
+(You'll probably need to be root to do this.)  We recommend first saying
+	make -n install
+to see where configure thought the files should go.  You may need to edit
+the Makefile, particularly if your system's conventions for man page
+filenames don't match what configure expects.
+
+If you want to install the IJG library itself, for use in compiling other
+programs besides ours, then you need to put the four include files
+	jpeglib.h jerror.h jconfig.h jmorecfg.h
+into your include-file directory, and put the library file libjpeg.a
+(extension may vary depending on system) wherever library files go.
+If you generated a Makefile with "configure", it will do what it thinks
+is the right thing if you say
+	make install-lib
+
+
+OPTIONAL STUFF
+==============
+
+Progress monitor:
+
+If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display
+of percent-done progress reports.  The routine provided in cdjpeg.c merely
+prints percentages to stderr, but you can customize it to do something
+fancier.
+
+Utah RLE file format support:
+
+We distribute the software with support for RLE image files (Utah Raster
+Toolkit format) disabled, because the RLE support won't compile without the
+Utah library.  If you have URT version 3.1 or later, you can enable RLE
+support as follows:
+	1.  #define RLE_SUPPORTED in jconfig.h.
+	2.  Add a -I option to CFLAGS in the Makefile for the directory
+	    containing the URT .h files (typically the "include"
+	    subdirectory of the URT distribution).
+	3.  Add -L... -lrle to LDLIBS in the Makefile, where ... specifies
+	    the directory containing the URT "librle.a" file (typically the
+	    "lib" subdirectory of the URT distribution).
+
+Support for 12-bit-deep pixel data:
+
+The JPEG standard allows either 8-bit or 12-bit data precision.  (For color,
+this means 8 or 12 bits per channel, of course.)  If you need to work with
+deeper than 8-bit data, you can compile the IJG code for 12-bit operation.
+To do so:
+  1. In jmorecfg.h, define BITS_IN_JSAMPLE as 12 rather than 8.
+  2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED,
+     because the code for those formats doesn't handle 12-bit data and won't
+     even compile.  (The PPM code does work, as explained below.  The GIF
+     code works too; it scales 8-bit GIF data to and from 12-bit depth
+     automatically.)
+  3. Compile.  Don't expect "make test" to pass, since the supplied test
+     files are for 8-bit data.
+
+Currently, 12-bit support does not work on 16-bit-int machines.
+
+Note that a 12-bit version will not read 8-bit JPEG files, nor vice versa;
+so you'll want to keep around a regular 8-bit compilation as well.
+(Run-time selection of data depth, to allow a single copy that does both,
+is possible but would probably slow things down considerably; it's very low
+on our to-do list.)
+
+The PPM reader (rdppm.c) can read 12-bit data from either text-format or
+binary-format PPM and PGM files.  Binary-format PPM/PGM files which have a
+maxval greater than 255 are assumed to use 2 bytes per sample, LSB first
+(little-endian order).  As of early 1995, 2-byte binary format is not
+officially supported by the PBMPLUS library, but it is expected that a
+future release of PBMPLUS will support it.  Note that the PPM reader will
+read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming
+data is automatically rescaled to either maxval=255 or maxval=4095 as
+appropriate for the cjpeg bit depth.
+
+The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM
+format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12.  Since this
+format is not yet widely supported, you can disable it by compiling wrppm.c
+with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a
+standard 1-byte/sample PPM or PGM file.  (Yes, this means still another copy
+of djpeg to keep around.  But hopefully you won't need it for very long.
+Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.)
+
+Of course, if you are working with 12-bit data, you probably have it stored
+in some other, nonstandard format.  In that case you'll probably want to
+write your own I/O modules to read and write your format.
+
+Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in
+order to generate valid Huffman tables.  This is necessary because our
+default Huffman tables only cover 8-bit data.
+
+Removing code:
+
+If you need to make a smaller version of the JPEG software, some optional
+functions can be removed at compile time.  See the xxx_SUPPORTED #defines in
+jconfig.h and jmorecfg.h.  If at all possible, we recommend that you leave in
+decoder support for all valid JPEG files, to ensure that you can read anyone's
+output.  Taking out support for image file formats that you don't use is the
+most painless way to make the programs smaller.  Another possibility is to
+remove some of the DCT methods: in particular, the "IFAST" method may not be
+enough faster than the others to be worth keeping on your machine.  (If you
+do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST
+to a supported method, by adding a #define in jconfig.h.)
+
+
+OPTIMIZATION
+============
+
+Unless you own a Cray, you'll probably be interested in making the JPEG
+software go as fast as possible.  This section covers some machine-dependent
+optimizations you may want to try.  We suggest that before trying any of
+this, you first get the basic installation to pass the self-test step.
+Repeat the self-test after any optimization to make sure that you haven't
+broken anything.
+
+The integer DCT routines perform a lot of multiplications.  These
+multiplications must yield 32-bit results, but none of their input values
+are more than 16 bits wide.  On many machines, notably the 680x0 and 80x86
+CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32
+bit multiply.  Unfortunately there is no portable way to specify such a
+multiplication in C, but some compilers can generate one when you use the
+right combination of casts.  See the MULTIPLYxxx macro definitions in
+jdct.h.  If your compiler makes "int" be 32 bits and "short" be 16 bits,
+defining SHORTxSHORT_32 is fairly likely to work.  When experimenting with
+alternate definitions, be sure to test not only whether the code still works
+(use the self-test), but also whether it is actually faster --- on some
+compilers, alternate definitions may compute the right answer, yet be slower
+than the default.  Timing cjpeg on a large PGM (grayscale) input file is the
+best way to check this, as the DCT will be the largest fraction of the runtime
+in that mode.  (Note: some of the distributed compiler-specific jconfig files
+already contain #define switches to select appropriate MULTIPLYxxx
+definitions.)
+
+If your machine has sufficiently fast floating point hardware, you may find
+that the float DCT method is faster than the integer DCT methods, even
+after tweaking the integer multiply macros.  In that case you may want to
+make the float DCT be the default method.  (The only objection to this is
+that float DCT results may vary slightly across machines.)  To do that, add
+"#define JDCT_DEFAULT JDCT_FLOAT" to jconfig.h.  Even if you don't change
+the default, you should redefine JDCT_FASTEST, which is the method selected
+by djpeg's -fast switch.  Don't forget to update the documentation files
+(usage.doc and/or cjpeg.1, djpeg.1) to agree with what you've done.
+
+If access to "short" arrays is slow on your machine, it may be a win to
+define type JCOEF as int rather than short.  This will cost a good deal of
+memory though, particularly in some multi-pass modes, so don't do it unless
+you have memory to burn and short is REALLY slow.
+
+If your compiler can compile function calls in-line, make sure the INLINE
+macro in jmorecfg.h is defined as the keyword that marks a function
+inline-able.  Some compilers have a switch that tells the compiler to inline
+any function it thinks is profitable (e.g., -finline-functions for gcc).
+Enabling such a switch is likely to make the compiled code bigger but faster.
+
+In general, it's worth trying the maximum optimization level of your compiler,
+and experimenting with any optional optimizations such as loop unrolling.
+(Unfortunately, far too many compilers have optimizer bugs ... be prepared to
+back off if the code fails self-test.)  If you do any experimentation along
+these lines, please report the optimal settings to jpeg-info@uunet.uu.net so
+we can mention them in future releases.  Be sure to specify your machine and
+compiler version.
+
+
+HINTS FOR SPECIFIC SYSTEMS
+==========================
+
+We welcome reports on changes needed for systems not mentioned here.  Submit
+'em to jpeg-info@uunet.uu.net.  Also, if configure or ckconfig.c is wrong
+about how to configure the JPEG software for your system, please let us know.
+
+
+Acorn RISC OS:
+
+(Thanks to Simon Middleton for these hints on compiling with Desktop C.)
+After renaming the files according to Acorn conventions, take a copy of
+makefile.ansi, change all occurrences of 'libjpeg.a' to 'libjpeg.o' and
+change these definitions as indicated:
+
+CFLAGS= -throwback -IC: -Wn
+LDLIBS=C:o.Stubs
+SYSDEPMEM=jmemansi.o
+LN=Link
+AR=LibFile -c -o
+
+Also add a new line '.c.o:; $(cc) $< $(cflags) -c -o $@'.  Remove the
+lines '$(RM) libjpeg.o' and '$(AR2) libjpeg.o' and the 'jconfig.h'
+dependency section.
+
+Copy jconfig.doc to jconfig.h.  Edit jconfig.h to define TWO_FILE_COMMANDLINE
+and CHAR_IS_UNSIGNED.
+
+Run the makefile using !AMU not !Make.  If you want to use the 'clean' and
+'test' makefile entries then you will have to fiddle with the syntax a bit
+and rename the test files.
+
+
+Amiga:
+
+SAS C 6.50 reportedly is too buggy to compile the IJG code properly.
+A patch to update to 6.51 is available from SAS or AmiNet FTP sites.
+
+The supplied config files are set up to use jmemname.c as the memory
+manager, with temporary files being created on the device named by
+"JPEGTMP:".
+
+
+Atari ST/STE/TT:
+ 
+Copy the project files makcjpeg.st, makdjpeg.st, maktjpeg.st, and makljpeg.st
+to cjpeg.prj, djpeg.prj, jpegtran.prj, and libjpeg.prj respectively.  The
+project files should work as-is with Pure C.  For Turbo C, change library
+filenames "pc..." to "tc..." in each project file.  Note that libjpeg.prj
+selects jmemansi.c as the recommended memory manager.  You'll probably want to
+adjust the DEFAULT_MAX_MEM setting --- you want it to be a couple hundred K
+less than your normal free memory.  Put "#define DEFAULT_MAX_MEM nnnn" into
+jconfig.h to do this.
+
+To use the 68881/68882 coprocessor for the floating point DCT, add the
+compiler option "-8" to the project files and replace pcfltlib.lib with
+pc881lib.lib in cjpeg.prj and djpeg.prj.  Or if you don't have a
+coprocessor, you may prefer to remove the float DCT code by undefining
+DCT_FLOAT_SUPPORTED in jmorecfg.h (since without a coprocessor, the float
+code will be too slow to be useful).  In that case, you can delete
+pcfltlib.lib from the project files.
+
+Note that you must make libjpeg.lib before making cjpeg.ttp, djpeg.ttp,
+or jpegtran.ttp.  You'll have to perform the self-test by hand.
+
+We haven't bothered to include project files for rdjpgcom and wrjpgcom.
+Those source files should just be compiled by themselves; they don't
+depend on the JPEG library.
+
+There is a bug in some older versions of the Turbo C library which causes the
+space used by temporary files created with "tmpfile()" not to be freed after
+an abnormal program exit.  If you check your disk afterwards, you will find
+cluster chains that are allocated but not used by a file.  This should not
+happen in cjpeg/djpeg/jpegtran, since we enable a signal catcher to explicitly
+close temp files before exiting.  But if you use the JPEG library with your
+own code, be sure to supply a signal catcher, or else use a different
+system-dependent memory manager.
+
+
+Cray:
+
+Should you be so fortunate as to be running JPEG on a Cray YMP, there is a
+compiler bug in old versions of Cray's Standard C (prior to 3.1).  If you
+still have an old compiler, you'll need to insert a line reading
+"#pragma novector" just before the loop	
+    for (i = 1; i <= (int) htbl->bits[l]; i++)
+      huffsize[p++] = (char) l;
+in fix_huff_tbl (in V5beta1, line 204 of jchuff.c and line 176 of jdhuff.c).
+[This bug may or may not still occur with the current IJG code, but it's
+probably a dead issue anyway...]
+
+
+HP-UX:
+
+If you have HP-UX 7.05 or later with the "software development" C compiler,
+you should run the compiler in ANSI mode.  If using the configure script,
+say
+	./configure CC='cc -Aa'
+(or -Ae if you prefer).  If configuring by hand, use makefile.ansi and add
+"-Aa" to the CFLAGS line in the makefile.
+
+If you have a pre-7.05 system, or if you are using the non-ANSI C compiler
+delivered with a minimum HP-UX system, then you must use makefile.unix
+(and do NOT add -Aa); or just run configure without the CC option.
+
+On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior
+to A.08.07.  If you get complaints about "not a typedef name", you'll have to
+use makefile.unix, or run configure without the CC option.
+
+
+Macintosh, generic comments:
+
+The supplied user-interface files (cjpeg.c, djpeg.c, etc) are set up to
+provide a Unix-style command line interface.  You can use this interface on
+the Mac by means of the ccommand() library routine provided by Metrowerks
+CodeWarrior or Think C.  This is only appropriate for testing the library,
+however; to make a user-friendly equivalent of cjpeg/djpeg you'd really want
+to develop a Mac-style user interface.  There isn't a complete example
+available at the moment, but there are some helpful starting points:
+1. Sam Bushell's free "To JPEG" applet provides drag-and-drop conversion to
+JPEG under System 7 and later.  This only illustrates how to use the
+compression half of the library, but it does a very nice job of that part.
+The CodeWarrior source code is available from http://www.pobox.com/~jsam.
+2. Jim Brunner prepared a Mac-style user interface for both compression and
+decompression.  Unfortunately, it hasn't been updated since IJG v4, and
+the library's API has changed considerably since then.  Still it may be of
+some help, particularly as a guide to compiling the IJG code under Think C.
+Jim's code is available from the Info-Mac archives, at sumex-aim.stanford.edu
+or mirrors thereof; see file /info-mac/dev/src/jpeg-convert-c.hqx.
+
+jmemmac.c is the recommended memory manager back end for Macintosh.  It uses
+NewPtr/DisposePtr instead of malloc/free, and has a Mac-specific
+implementation of jpeg_mem_available().  It also creates temporary files that
+follow Mac conventions.  (That part of the code relies on System-7-or-later OS
+functions.  See the comments in jmemmac.c if you need to run it on System 6.)
+NOTE that USE_MAC_MEMMGR must be defined in jconfig.h to use jmemmac.c.
+
+You can also use jmemnobs.c, if you don't care about handling images larger
+than available memory.  If you use any memory manager back end other than
+jmemmac.c, we recommend replacing "malloc" and "free" by "NewPtr" and
+"DisposePtr", because Mac C libraries often have peculiar implementations of
+malloc/free.  (For instance, free() may not return the freed space to the
+Mac Memory Manager.  This is undesirable for the IJG code because jmemmgr.c
+already clumps space requests.)
+
+
+Macintosh, Metrowerks CodeWarrior:
+
+The Unix-command-line-style interface can be used by defining USE_CCOMMAND.
+You'll also need to define TWO_FILE_COMMANDLINE to avoid stdin/stdout.
+This means that when using the cjpeg/djpeg programs, you'll have to type the
+input and output file names in the "Arguments" text-edit box, rather than
+using the file radio buttons.  (Perhaps USE_FDOPEN or USE_SETMODE would
+eliminate the problem, but I haven't heard from anyone who's tried it.)
+
+On 680x0 Macs, Metrowerks defines type "double" as a 10-byte IEEE extended
+float.  jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power
+of 2.  Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.
+
+The supplied configuration file jconfig.mac can be used for your jconfig.h;
+it includes all the recommended symbol definitions.  If you have AppleScript
+installed, you can run the supplied script makeproj.mac to create CodeWarrior
+project files for the library and the testbed applications, then build the
+library and applications.  (Thanks to Dan Sears and Don Agro for this nifty
+hack, which saves us from trying to maintain CodeWarrior project files as part
+of the IJG distribution...)
+
+
+Macintosh, Think C:
+
+The documentation in Jim Brunner's "JPEG Convert" source code (see above)
+includes detailed build instructions for Think C; it's probably somewhat
+out of date for the current release, but may be helpful.
+
+If you want to build the minimal command line version, proceed as follows.
+You'll have to prepare project files for the programs; we don't include any
+in the distribution since they are not text files.  Use the file lists in
+any of the supplied makefiles as a guide.  Also add the ANSI and Unix C
+libraries in a separate segment.  You may need to divide the JPEG files into
+more than one segment; we recommend dividing compression and decompression
+modules.  Define USE_CCOMMAND in jconfig.h so that the ccommand() routine is
+called.  You must also define TWO_FILE_COMMANDLINE because stdin/stdout
+don't handle binary data correctly.
+
+On 680x0 Macs, Think C defines type "double" as a 12-byte IEEE extended float.
+jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power of 2.
+Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.
+
+jconfig.mac should work as a jconfig.h configuration file for Think C,
+but the makeproj.mac AppleScript script is specific to CodeWarrior.  Sorry.
+
+
+MIPS R3000:
+
+MIPS's cc version 1.31 has a rather nasty optimization bug.  Don't use -O
+if you have that compiler version.  (Use "cc -V" to check the version.)
+Note that the R3000 chip is found in workstations from DEC and others.
+
+
+MS-DOS, generic comments for 16-bit compilers:
+
+The IJG code is designed to work well in 80x86 "small" or "medium" memory
+models (i.e., data pointers are 16 bits unless explicitly declared "far";
+code pointers can be either size).  You may be able to use small model to
+compile cjpeg or djpeg by itself, but you will probably have to use medium
+model for any larger application.  This won't make much difference in
+performance.  You *will* take a noticeable performance hit if you use a
+large-data memory model, and you should avoid "huge" model if at all
+possible.  Be sure that NEED_FAR_POINTERS is defined in jconfig.h if you use
+a small-data memory model; be sure it is NOT defined if you use a large-data
+model.  (The supplied makefiles and jconfig files for Borland and Microsoft C
+compile in medium model and define NEED_FAR_POINTERS.)
+
+The DOS-specific memory manager, jmemdos.c, should be used if possible.
+It needs some assembly-code routines which are in jmemdosa.asm; make sure
+your makefile assembles that file and includes it in the library.  If you
+don't have a suitable assembler, you can get pre-assembled object files for
+jmemdosa by FTP from ftp.uu.net:/graphics/jpeg/jdosaobj.zip.  (DOS-oriented
+distributions of the IJG source code often include these object files.)
+
+When using jmemdos.c, jconfig.h must define USE_MSDOS_MEMMGR and must set
+MAX_ALLOC_CHUNK to less than 64K (65520L is a typical value).  If your
+C library's far-heap malloc() can't allocate blocks that large, reduce
+MAX_ALLOC_CHUNK to whatever it can handle.
+
+If you can't use jmemdos.c for some reason --- for example, because you
+don't have an assembler to assemble jmemdosa.asm --- you'll have to fall
+back to jmemansi.c or jmemname.c.  You'll probably still need to set
+MAX_ALLOC_CHUNK in jconfig.h, because most DOS C libraries won't malloc()
+more than 64K at a time.  IMPORTANT: if you use jmemansi.c or jmemname.c,
+you will have to compile in a large-data memory model in order to get the
+right stdio library.  Too bad.
+
+wrjpgcom needs to be compiled in large model, because it malloc()s a 64KB
+work area to hold the comment text.  If your C library's malloc can't
+handle that, reduce MAX_COM_LENGTH as necessary in wrjpgcom.c.
+
+Most MS-DOS compilers treat stdin/stdout as text files, so you must use
+two-file command line style.  But if your compiler has either fdopen() or
+setmode(), you can use one-file style if you like.  To do this, define
+USE_SETMODE or USE_FDOPEN so that stdin/stdout will be set to binary mode.
+(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.)  You
+should test that I/O through stdin/stdout produces the same results as I/O
+to explicitly named files... the "make test" procedures in the supplied
+makefiles do NOT use stdin/stdout.
+
+
+MS-DOS, generic comments for 32-bit compilers:
+
+None of the above comments about memory models apply if you are using a
+32-bit flat-memory-space environment, such as DJGPP or Watcom C.  (And you
+should use one if you have it, as performance will be much better than
+8086-compatible code!)  For flat-memory-space compilers, do NOT define
+NEED_FAR_POINTERS, and do NOT use jmemdos.c.  Use jmemnobs.c if the
+environment supplies adequate virtual memory, otherwise use jmemansi.c or
+jmemname.c.
+
+You'll still need to be careful about binary I/O through stdin/stdout.
+See the last paragraph of the previous section.
+
+
+MS-DOS, Borland C:
+
+Be sure to convert all the source files to DOS text format (CR/LF newlines).
+Although Borland C will often work OK with unmodified Unix (LF newlines)
+source files, sometimes it will give bogus compile errors.
+"Illegal character '#'" is the most common such error.  (This is true with
+Borland C 3.1, but perhaps is fixed in newer releases.)
+
+If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.
+jconfig.bcc already includes #define USE_SETMODE to make this work.
+(fdopen does not work correctly.)
+
+
+MS-DOS, Microsoft C:
+
+makefile.mc6 works with Microsoft C, DOS Visual C++, etc.  It should only
+be used if you want to build a 16-bit (small or medium memory model) program.
+
+If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.
+jconfig.mc6 already includes #define USE_SETMODE to make this work.
+(fdopen does not work correctly.)
+
+Note that this makefile assumes that the working copy of itself is called
+"makefile".  If you want to call it something else, say "makefile.mak",
+be sure to adjust the dependency line that reads "$(RFILE) : makefile".
+Otherwise the make will fail because it doesn't know how to create "makefile".
+Worse, some releases of Microsoft's make utilities give an incorrect error
+message in this situation.
+
+Old versions of MS C fail with an "out of macro expansion space" error
+because they can't cope with the macro TRACEMS8 (defined in jerror.h).
+If this happens to you, the easiest solution is to change TRACEMS8 to
+expand to nothing.  You'll lose the ability to dump out JPEG coefficient
+tables with djpeg -debug -debug, but at least you can compile.
+
+Original MS C 6.0 is very buggy; it compiles incorrect code unless you turn
+off optimization entirely (remove -O from CFLAGS).  6.00A is better, but it
+still generates bad code if you enable loop optimizations (-Ol or -Ox).
+
+MS C 8.0 crashes when compiling jquant1.c with optimization switch /Oo ...
+which is on by default.  To work around this bug, compile that one file
+with /Oo-.
+
+
+Microsoft Windows (all versions), generic comments:
+
+Some Windows system include files define typedef boolean as "unsigned char".
+The IJG code also defines typedef boolean, but we make it "int" by default.
+This doesn't affect the IJG programs because we don't import those Windows
+include files.  But if you use the JPEG library in your own program, and some
+of your program's files import one definition of boolean while some import the
+other, you can get all sorts of mysterious problems.  A good preventive step
+is to make the IJG library use "unsigned char" for boolean.  To do that,
+add something like this to your jconfig.h file:
+	/* Define "boolean" as unsigned char, not int, per Windows custom */
+	#ifndef __RPCNDR_H__	/* don't conflict if rpcndr.h already read */
+	typedef unsigned char boolean;
+	#endif
+	#define HAVE_BOOLEAN	/* prevent jmorecfg.h from redefining it */
+(This is already in jconfig.vc, by the way.)
+
+windef.h contains the declarations
+	#define far
+	#define FAR far
+Since jmorecfg.h tries to define FAR as empty, you may get a compiler
+warning if you include both jpeglib.h and windef.h (which windows.h
+includes).  To suppress the warning, you can put "#ifndef FAR"/"#endif"
+around the line "#define FAR" in jmorecfg.h.
+
+When using the library in a Windows application, you will almost certainly
+want to modify or replace the error handler module jerror.c, since our
+default error handler does a couple of inappropriate things:
+  1. it tries to write error and warning messages on stderr;
+  2. in event of a fatal error, it exits by calling exit().
+
+A simple stopgap solution for problem 1 is to replace the line
+	fprintf(stderr, "%s\n", buffer);
+(in output_message in jerror.c) with
+	MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR);
+It's highly recommended that you at least do that much, since otherwise
+error messages will disappear into nowhere.  (Beginning with IJG v6b, this
+code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in
+jconfig.h to enable it.)
+
+The proper solution for problem 2 is to return control to your calling
+application after a library error.  This can be done with the setjmp/longjmp
+technique discussed in libjpeg.doc and illustrated in example.c.  (NOTE:
+some older Windows C compilers provide versions of setjmp/longjmp that
+don't actually work under Windows.  You may need to use the Windows system
+functions Catch and Throw instead.)
+
+The recommended memory manager under Windows is jmemnobs.c; in other words,
+let Windows do any virtual memory management needed.  You should NOT use
+jmemdos.c nor jmemdosa.asm under Windows.
+
+For Windows 3.1, we recommend compiling in medium or large memory model;
+for newer Windows versions, use a 32-bit flat memory model.  (See the MS-DOS
+sections above for more info about memory models.)  In the 16-bit memory
+models only, you'll need to put
+	#define MAX_ALLOC_CHUNK 65520L	/* Maximum request to malloc() */
+into jconfig.h to limit allocation chunks to 64Kb.  (Without that, you'd
+have to use huge memory model, which slows things down unnecessarily.)
+jmemnobs.c works without modification in large or flat memory models, but to
+use medium model, you need to modify its jpeg_get_large and jpeg_free_large
+routines to allocate far memory.  In any case, you might like to replace
+its calls to malloc and free with direct calls on Windows memory allocation
+functions.
+
+You may also want to modify jdatasrc.c and jdatadst.c to use Windows file
+operations rather than fread/fwrite.  This is only necessary if your C
+compiler doesn't provide a competent implementation of C stdio functions.
+
+You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library
+will accept or deliver color pixels in BGR sample order, not RGB; BGR order
+is usually more convenient under Windows.  Note that this change will break
+the sample applications cjpeg/djpeg, but the library itself works fine.
+
+
+Many people want to convert the IJG library into a DLL.  This is reasonably
+straightforward, but watch out for the following:
+
+  1. Don't try to compile as a DLL in small or medium memory model; use
+large model, or even better, 32-bit flat model.  Many places in the IJG code
+assume the address of a local variable is an ordinary (not FAR) pointer;
+that isn't true in a medium-model DLL.
+
+  2. Microsoft C cannot pass file pointers between applications and DLLs.
+(See Microsoft Knowledge Base, PSS ID Number Q50336.)  So jdatasrc.c and
+jdatadst.c don't work if you open a file in your application and then pass
+the pointer to the DLL.  One workaround is to make jdatasrc.c/jdatadst.c
+part of your main application rather than part of the DLL.
+
+  3. You'll probably need to modify the macros GLOBAL() and EXTERN() to
+attach suitable linkage keywords to the exported routine names.  Similarly,
+you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers
+are declared in a way that lets application routines be called back through
+the function pointers.  These macros are in jmorecfg.h.  Typical definitions
+for a 16-bit DLL are:
+	#define GLOBAL(type)		type _far _pascal _loadds _export
+	#define EXTERN(type)		extern type _far _pascal _loadds
+	#define METHODDEF(type)		static type _far _pascal
+	#define JMETHOD(type,methodname,arglist)  \
+		type (_far _pascal *methodname) arglist
+For a 32-bit DLL you may want something like
+	#define GLOBAL(type)		__declspec(dllexport) type
+	#define EXTERN(type)		extern __declspec(dllexport) type
+Although not all the GLOBAL routines are actually intended to be called by
+the application, the performance cost of making them all DLL entry points is
+negligible.
+
+The unmodified IJG library presents a very C-specific application interface,
+so the resulting DLL is only usable from C or C++ applications.  There has
+been some talk of writing wrapper code that would present a simpler interface
+usable from other languages, such as Visual Basic.  This is on our to-do list
+but hasn't been very high priority --- any volunteers out there?
+
+
+Microsoft Windows, Borland C:
+
+The provided jconfig.bcc should work OK in a 32-bit Windows environment,
+but you'll need to tweak it in a 16-bit environment (you'd need to define
+NEED_FAR_POINTERS and MAX_ALLOC_CHUNK).  Beware that makefile.bcc will need
+alteration if you want to use it for Windows --- in particular, you should
+use jmemnobs.c not jmemdos.c under Windows.
+
+Borland C++ 4.5 fails with an internal compiler error when trying to compile
+jdmerge.c in 32-bit mode.  If enough people complain, perhaps Borland will fix
+it.  In the meantime, the simplest known workaround is to add a redundant
+definition of the variable range_limit in h2v1_merged_upsample(), at the head
+of the block that handles odd image width (about line 268 in v6 jdmerge.c):
+  /* If image width is odd, do the last output column separately */
+  if (cinfo->output_width & 1) {
+    register JSAMPLE * range_limit = cinfo->sample_range_limit; /* ADD THIS */
+    cb = GETJSAMPLE(*inptr1);
+Pretty bizarre, especially since the very similar routine h2v2_merged_upsample
+doesn't trigger the bug.
+Recent reports suggest that this bug does not occur with "bcc32a" (the
+Pentium-optimized version of the compiler).
+
+Another report from a user of Borland C 4.5 was that incorrect code (leading
+to a color shift in processed images) was produced if any of the following
+optimization switch combinations were used: 
+	-Ot -Og
+	-Ot -Op
+	-Ot -Om
+So try backing off on optimization if you see such a problem.  (Are there
+several different releases all numbered "4.5"??)
+
+
+Microsoft Windows, Microsoft Visual C++:
+
+jconfig.vc should work OK with any Microsoft compiler for a 32-bit memory
+model.  makefile.vc is intended for command-line use.  (If you are using
+the Developer Studio environment, you may prefer the DevStudio project
+files; see below.)
+
+Some users feel that it's easier to call the library from C++ code if you
+force VC++ to treat the library as C++ code, which you can do by renaming
+all the *.c files to *.cpp (and adjusting the makefile to match).  This
+avoids the need to put extern "C" { ... } around #include "jpeglib.h" in
+your C++ application.
+
+
+Microsoft Windows, Microsoft Developer Studio:
+
+We include makefiles that should work as project files in DevStudio 4.2 or
+later.  There is a library makefile that builds the IJG library as a static
+Win32 library, and an application makefile that builds the sample applications
+as Win32 console applications.  (Even if you only want the library, we
+recommend building the applications so that you can run the self-test.)
+
+To use:
+1. Copy jconfig.vc to jconfig.h, makelib.ds to jpeg.mak, and
+   makeapps.ds to apps.mak.  (Note that the renaming is critical!)
+2. Click on the .mak files to construct project workspaces.
+   (If you are using DevStudio more recent than 4.2, you'll probably
+   get a message saying that the makefiles are being updated.)
+3. Build the library project, then the applications project.
+4. Move the application .exe files from `app`\Release to an
+   appropriate location on your path.
+5. To perform the self-test, execute the command line
+	NMAKE /f makefile.vc  test
+
+
+OS/2, Borland C++:
+
+Watch out for optimization bugs in older Borland compilers; you may need
+to back off the optimization switch settings.  See the comments in
+makefile.bcc.
+
+
+SGI:
+
+On some SGI systems, you may need to set "AR2= ar -ts" in the Makefile.
+If you are using configure, you can do this by saying
+	./configure RANLIB='ar -ts'
+This change is not needed on all SGIs.  Use it only if the make fails at the
+stage of linking the completed programs.
+
+On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2"
+reportedly speeds up the float DCT method substantially, enough to make it
+faster than the default int method (but still slower than the fast int
+method).  If you use -mips2, you may want to alter the default DCT method to
+be float.  To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h.
+
+
+VMS:
+
+On an Alpha/VMS system with MMS, be sure to use the "/Marco=Alpha=1"
+qualifier with MMS when building the JPEG package.
+
+VAX/VMS v5.5-1 may have problems with the test step of the build procedure
+reporting differences when it compares the original and test images.  If the
+error points to the last block of the files, it is most likely bogus and may
+be safely ignored.  It seems to be because the files are Stream_LF and
+Backup/Compare has difficulty with the (presumably) null padded files.
+This problem was not observed on VAX/VMS v6.1 or AXP/VMS v6.1.

+/*
+ * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
+ * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
+ * The conversion equations to be implemented are therefore
+ *	Y  =  0.29900 * R + 0.58700 * G + 0.11400 * B
+ *	Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B  + CENTERJSAMPLE
+ *	Cr =  0.50000 * R - 0.41869 * G - 0.08131 * B  + CENTERJSAMPLE
+ * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
+ * Note: older versions of the IJG code used a zero offset of MAXJSAMPLE/2,
+ * rather than CENTERJSAMPLE, for Cb and Cr.  This gave equal positive and
+ * negative swings for Cb/Cr, but meant that grayscale values (Cb=Cr=0)
+ * were not represented exactly.  Now we sacrifice exact representation of
+ * maximum red and maximum blue in order to get exact grayscales.
+ *
+ * To avoid floating-point arithmetic, we represent the fractional constants
+ * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
+ * the products by 2^16, with appropriate rounding, to get the correct answer.
+ *
+ * For even more speed, we avoid doing any multiplications in the inner loop
+ * by precalculating the constants times R,G,B for all possible values.
+ * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
+ * for 12-bit samples it is still acceptable.  It's not very reasonable for
+ * 16-bit samples, but if you want lossless storage you shouldn't be changing
+ * colorspace anyway.
+ * The CENTERJSAMPLE offsets and the rounding fudge-factor of 0.5 are included
+ * in the tables to save adding them separately in the inner loop.

+ * codewords, this just means that there must be an unused slot in the

+ * including it in the symbol set anyway should give a better Huffman code.
+ * But the theoretically better code actually seems to come out worse in
+ * practice, because it produces more all-ones bytes (which incur stuffed
+ * zero bytes in the final file).  In any case the difference is tiny.
+ *
+ * The JPEG standard requires Huffman codes to be no more than 16 bits long.
+ * If some symbols have a very small but nonzero probability, the Huffman tree
+ * must be adjusted to meet the code length restriction.  We currently use
+ * the adjustment method suggested in JPEG section K.2.  This method is *not*
+ * optimal; it may not choose the best possible limited-length code.  But
+ * typically only very-low-frequency symbols will be given less-than-optimal
+ * lengths, so the code is almost optimal.  Experimental comparisons against
+ * an optimal limited-length-code algorithm indicate that the difference is

+ * jcsample.c
+ *
+ * Copyright (C) 1991-1996, Thomas G. Lane.
+ * This file is part of the Independent JPEG Group's software.
+ * For conditions of distribution and use, see the accompanying README file.
+ *
+ * This file contains downsampling routines.
+ *
+ * Downsampling input data is counted in "row groups".  A row group
+ * is defined to be max_v_samp_factor pixel rows of each component,
+ * from which the downsampler produces v_samp_factor sample rows.
+ * A single row group is processed in each call to the downsampler module.
+ *
+ * The downsampler is responsible for edge-expansion of its output data
+ * to fill an integral number of DCT blocks horizontally.  The source buffer
+ * may be modified if it is helpful for this purpose (the source buffer is
+ * allocated wide enough to correspond to the desired output width).
+ * The caller (the prep controller) is responsible for vertical padding.
+ *
+ * The downsampler may request "context rows" by setting need_context_rows
+ * during startup.  In this case, the input arrays will contain at least
+ * one row group's worth of pixels above and below the passed-in data;
+ * the caller will create dummy rows at image top and bottom by replicating
+ * the first or last real pixel row.
+ *
+ * An excellent reference for image resampling is
+ *   Digital Image Warping, George Wolberg, 1990.
+ *   Pub. by IEEE Computer Society Press, Los Alamitos, CA. ISBN 0-8186-8944-7.
+ *
+ * The downsampling algorithm used here is a simple average of the source
+ * pixels covered by the output pixel.  The hi-falutin sampling literature
+ * refers to this as a "box filter".  In general the characteristics of a box
+ * filter are not very good, but for the specific cases we normally use (1:1
+ * and 2:1 ratios) the box is equivalent to a "triangle filter" which is not
+ * nearly so bad.  If you intend to use other sampling ratios, you'd be well
+ * advised to improve this code.
+ *
+ * A simple input-smoothing capability is provided.  This is mainly intended
+ * for cleaning up color-dithered GIF input files (if you find it inadequate,
+ * we suggest using an external filtering program such as pnmconvol).  When
+ * enabled, each input pixel P is replaced by a weighted sum of itself and its
+ * eight neighbors.  P's weight is 1-8*SF and each neighbor's weight is SF,
+ * where SF = (smoothing_factor / 1024).
+ * Currently, smoothing is only supported for 2h2v sampling factors.

+/*
+ * YCbCr is defined per CCIR 601-1, except that Cb and Cr are
+ * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.
+ * The conversion equations to be implemented are therefore
+ *	R = Y                + 1.40200 * Cr
+ *	G = Y - 0.34414 * Cb - 0.71414 * Cr
+ *	B = Y + 1.77200 * Cb
+ * where Cb and Cr represent the incoming values less CENTERJSAMPLE.
+ * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)
+ *
+ * To avoid floating-point arithmetic, we represent the fractional constants
+ * as integers scaled up by 2^16 (about 4 digits precision); we have to divide
+ * the products by 2^16, with appropriate rounding, to get the correct answer.
+ * Notice that Y, being an integral input, does not contribute any fraction
+ * so it need not participate in the rounding.
+ *
+ * For even more speed, we avoid doing any multiplications in the inner loop
+ * by precalculating the constants times Cb and Cr for all possible values.
+ * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);
+ * for 12-bit samples it is still acceptable.  It's not very reasonable for
+ * 16-bit samples, but if you want lossless storage you shouldn't be changing
+ * colorspace anyway.
+ * The Cr=>R and Cb=>B values can be rounded to integers in advance; the
+ * values for the G calculation are left scaled up, since we must add them
+ * together before rounding.

+/*
+ * In the current system design, the main buffer need never be a full-image
+ * buffer; any full-height buffers will be found inside the coefficient or
+ * postprocessing controllers.  Nonetheless, the main controller is not
+ * trivial.  Its responsibility is to provide context rows for upsampling/
+ * rescaling, and doing this in an efficient fashion is a bit tricky.
+ *
+ * Postprocessor input data is counted in "row groups".  A row group
+ * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size)
+ * sample rows of each component.  (We require DCT_scaled_size values to be
+ * chosen such that these numbers are integers.  In practice DCT_scaled_size
+ * values will likely be powers of two, so we actually have the stronger
+ * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.)
+ * Upsampling will typically produce max_v_samp_factor pixel rows from each
+ * row group (times any additional scale factor that the upsampler is
+ * applying).
+ *
+ * The coefficient controller will deliver data to us one iMCU row at a time;
+ * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or
+ * exactly min_DCT_scaled_size row groups.  (This amount of data corresponds
+ * to one row of MCUs when the image is fully interleaved.)  Note that the
+ * number of sample rows varies across components, but the number of row
+ * groups does not.  Some garbage sample rows may be included in the last iMCU
+ * row at the bottom of the image.
+ *
+ * Depending on the vertical scaling algorithm used, the upsampler may need
+ * access to the sample row(s) above and below its current input row group.
+ * The upsampler is required to set need_context_rows TRUE at global selection
+ * time if so.  When need_context_rows is FALSE, this controller can simply
+ * obtain one iMCU row at a time from the coefficient controller and dole it
+ * out as row groups to the postprocessor.
+ *
+ * When need_context_rows is TRUE, this controller guarantees that the buffer
+ * passed to postprocessing contains at least one row group's worth of samples
+ * above and below the row group(s) being processed.  Note that the context
+ * rows "above" the first passed row group appear at negative row offsets in
+ * the passed buffer.  At the top and bottom of the image, the required
+ * context rows are manufactured by duplicating the first or last real sample
+ * row; this avoids having special cases in the upsampling inner loops.
+ *
+ * The amount of context is fixed at one row group just because that's a
+ * convenient number for this controller to work with.  The existing
+ * upsamplers really only need one sample row of context.  An upsampler
+ * supporting arbitrary output rescaling might wish for more than one row
+ * group of context when shrinking the image; tough, we don't handle that.
+ * (This is justified by the assumption that downsizing will be handled mostly
+ * by adjusting the DCT_scaled_size values, so that the actual scale factor at
+ * the upsample step needn't be much less than one.)
+ *
+ * To provide the desired context, we have to retain the last two row groups
+ * of one iMCU row while reading in the next iMCU row.  (The last row group
+ * can't be processed until we have another row group for its below-context,
+ * and so we have to save the next-to-last group too for its above-context.)
+ * We could do this most simply by copying data around in our buffer, but
+ * that'd be very slow.  We can avoid copying any data by creating a rather
+ * strange pointer structure.  Here's how it works.  We allocate a workspace
+ * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number
+ * of row groups per iMCU row).  We create two sets of redundant pointers to
+ * the workspace.  Labeling the physical row groups 0 to M+1, the synthesized
+ * pointer lists look like this:
+ *                   M+1                          M-1
+ * master pointer --> 0         master pointer --> 0
+ *                    1                            1
+ *                   ...                          ...
+ *                   M-3                          M-3
+ *                   M-2                           M
+ *                   M-1                          M+1
+ *                    M                           M-2
+ *                   M+1                          M-1
+ *                    0                            0
+ * We read alternate iMCU rows using each master pointer; thus the last two
+ * row groups of the previous iMCU row remain un-overwritten in the workspace.
+ * The pointer lists are set up so that the required context rows appear to
+ * be adjacent to the proper places when we pass the pointer lists to the
+ * upsampler.
+ *
+ * The above pictures describe the normal state of the pointer lists.
+ * At top and bottom of the image, we diddle the pointer lists to duplicate
+ * the first or last sample row as necessary (this is cheaper than copying
+ * sample rows around).
+ *
+ * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1.  In that
+ * situation each iMCU row provides only one row group so the buffering logic
+ * must be different (eg, we must read two iMCU rows before we can emit the
+ * first row group).  For now, we simply do not support providing context
+ * rows when min_DCT_scaled_size is 1.  That combination seems unlikely to
+ * be worth providing --- if someone wants a 1/8th-size preview, they probably
+ * want it quick and dirty, so a context-free upsampler is sufficient.

+ * Exit: if return TRUE, have read and processed any parameters, and have

+ *   will be called again after application supplies more input data.
+ *
+ * This approach to suspension assumes that all of a marker's parameters
+ * can fit into a single input bufferload.  This should hold for "normal"
+ * markers.  Some COM/APPn markers might have large parameter segments
+ * that might not fit.  If we are simply dropping such a marker, we use
+ * skip_input_data to get past it, and thereby put the problem on the
+ * source manager's shoulders.  If we are saving the marker's contents
+ * into memory, we use a slightly different convention: when forced to
+ * suspend, the marker processor updates the restart point to the end of
+ * what it's consumed (ie, the end of the buffer) before returning FALSE.
+ * On resumption, cinfo->unread_marker still contains the marker code,
+ * but the data source will point to the next chunk of marker data.
+ * The marker processor must retain internal state to deal with this.
+ *
+ * Note that we don't bother to avoid duplicate trace messages if a
+ * suspension occurs within marker parameters.  Other side effects
+ * require more care.

+ * the current data-source input point; usually it should be reset to zero
+ * before returning.
+ * Returns FALSE if suspension is required.
+ *
+ * This implementation is substantially constrained by wanting to treat the
+ * input as a data stream; this means we can't back up.  Therefore, we have
+ * only the following actions to work with:
+ *   1. Simply discard the marker and let the entropy decoder resume at next
+ *      byte of file.
+ *   2. Read forward until we find another marker, discarding intervening
+ *      data.  (In theory we could look ahead within the current bufferload,
+ *      without having to discard data if we don't find the desired marker.
+ *      This idea is not implemented here, in part because it makes behavior
+ *      dependent on buffer size and chance buffer-boundary positions.)
+ *   3. Leave the marker unread (by failing to zero cinfo->unread_marker).
+ *      This will cause the entropy decoder to process an empty data segment,
+ *      inserting dummy zeroes, and then we will reprocess the marker.
+ *
+ * #2 is appropriate if we think the desired marker lies ahead, while #3 is
+ * appropriate if the found marker is a future restart marker (indicating
+ * that we have missed the desired restart marker, probably because it got
+ * corrupted).
+ * We apply #2 or #3 if the found marker is a restart marker no more than
+ * two counts behind or ahead of the expected one.  We also apply #2 if the
+ * found marker is not a legal JPEG marker code (it's certainly bogus data).
+ * If the found marker is a restart marker more than 2 counts away, we do #1
+ * (too much risk that the marker is erroneous; with luck we will be able to
+ * resync at some future point).
+ * For any valid non-restart JPEG marker, we apply #3.  This keeps us from
+ * overrunning the end of a scan.  An implementation limited to single-scan
+ * files might find it better to apply #2 for markers other than EOI, since
+ * any other marker would have to be bogus data in that case.

+ * Several decompression processes need to range-limit values to the range

+ * processes are inner loops and need to be as fast as possible.  On most
+ * machines, particularly CPUs with pipelines or instruction prefetch,
+ * a (subscript-check-less) C table lookup
+ *		x = sample_range_limit[x];
+ * is faster than explicit tests
+ *		if (x < 0)  x = 0;
+ *		else if (x > MAXJSAMPLE)  x = MAXJSAMPLE;
+ * These processes all use a common table prepared by the routine below.
+ *
+ * For most steps we can mathematically guarantee that the initial value
+ * of x is within MAXJSAMPLE+1 of the legal range, so a table running from
+ * -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient.  But for the initial
+ * limiting step (just after the IDCT), a wildly out-of-range value is 
+ * possible if the input data is corrupt.  To avoid any chance of indexing
+ * off the end of memory and getting a bad-pointer trap, we perform the
+ * post-IDCT limiting thus:
+ *		x = range_limit[x & MASK];
+ * where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
+ * samples.  Under normal circumstances this is more than enough range and
+ * a correct output will be generated; with bogus input data the mask will
+ * cause wraparound, and we will safely generate a bogus-but-in-range output.
+ * For the post-IDCT step, we want to convert the data from signed to unsigned
+ * representation by adding CENTERJSAMPLE at the same time that we limit it.
+ * So the post-IDCT limiting table ends up looking like this:
+ *   CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
+ *   MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
+ *   0          (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
+ *   0,1,...,CENTERJSAMPLE-1
+ * Negative inputs select values from the upper half of the table after
+ * masking.
+ *
+ * We can save some space by overlapping the start of the post-IDCT table
+ * with the simpler range limiting table.  The post-IDCT table begins at
+ * sample_range_limit + CENTERJSAMPLE.

+ * Note that the table is allocated in near data space on PCs; it's small

+ *
+ * Copyright (C) 1994-1996, Thomas G. Lane.
+ * This file is part of the Independent JPEG Group's software.
+ * For conditions of distribution and use, see the accompanying README file.
+ *
+ * This file contains code for merged upsampling/color conversion.
+ *
+ * This file combines functions from jdsample.c and jdcolor.c;
+ * read those files first to understand what's going on.
+ *
+ * When the chroma components are to be upsampled by simple replication
+ * (ie, box filtering), we can save some work in color conversion by
+ * calculating all the output pixels corresponding to a pair of chroma
+ * samples at one time.  In the conversion equations
+ *	R = Y           + K1 * Cr
+ *	G = Y + K2 * Cb + K3 * Cr
+ *	B = Y + K4 * Cb
+ * only the Y term varies among the group of pixels corresponding to a pair
+ * of chroma samples, so the rest of the terms can be calculated just once.
+ * At typical sampling ratios, this eliminates half or three-quarters of the
+ * multiplications needed for color conversion.
+ *
+ * This file currently provides implementations for the following cases:
+ *	YCbCr => RGB color conversion only.
+ *	Sampling ratios of 2h1v or 2h2v.
+ *	No scaling needed at upsample time.
+ *	Corner-aligned (non-CCIR601) sampling alignment.
+ * Other special cases could be added, but in most applications these are
+ * the only common cases.  (For uncommon cases we fall back on the more
+ * general code in jdsample.c and jdcolor.c.)

+This archive contains already-assembled object files for JMEMDOSA.ASM
+of the Independent JPEG Group's JPEG package.  These files will be helpful
+if you want to compile the IJG code for DOS, but don't have an assembler.
+
+These files were prepared from the 3/13/1992 version of JMEMDOSA.ASM,
+which is still unchanged as of mid-1998.  You can use these files with
+releases 3 through 6 of the IJG code, and probably future releases too.
+
+To use these files, copy the proper version to JMEMDOSA.OBJ.  Make sure
+this file has a newer date than JMEMDOSA.ASM.  Then compile the code as
+usual.
+
+Object files included:
+
+JDOSAMSC.OBJ	For Microsoft C version 5 or later.
+JDOSABCC.OBJ	For Borland C version 3.0 or later.

+ * Copyright (C) 1994-1998, Thomas G. Lane.
+ * This file is part of the Independent JPEG Group's software.
+ * For conditions of distribution and use, see the accompanying README file.
+ *
+ * This file contains a floating-point implementation of the
+ * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
+ * must also perform dequantization of the input coefficients.
+ *
+ * This implementation should be more accurate than either of the integer
+ * IDCT implementations.  However, it may not give the same results on all
+ * machines because of differences in roundoff behavior.  Speed will depend
+ * on the hardware's floating point capacity.
+ *
+ * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
+ * on each row (or vice versa, but it's more convenient to emit a row at
+ * a time).  Direct algorithms are also available, but they are much more
+ * complex and seem not to be any faster when reduced to code.
+ *
+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for
+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell
+ * JPEG textbook (see REFERENCES section in file README).  The following code
+ * is based directly on figure 4-8 in P&M.
+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is
+ * possible to arrange the computation so that many of the multiplies are
+ * simple scalings of the final outputs.  These multiplies can then be
+ * folded into the multiplications or divisions by the JPEG quantization
+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
+ * to be done in the DCT itself.
+ * The primary disadvantage of this method is that with a fixed-point
+ * implementation, accuracy is lost due to imprecise representation of the
+ * scaled quantization values.  However, that problem does not arise if
+ * we use floating point arithmetic.

+ * This file is part of the Independent JPEG Group's software.

+ *
+ * This file contains a fast, not so accurate integer implementation of the
+ * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine
+ * must also perform dequantization of the input coefficients.
+ *
+ * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT
+ * on each row (or vice versa, but it's more convenient to emit a row at
+ * a time).  Direct algorithms are also available, but they are much more
+ * complex and seem not to be any faster when reduced to code.
+ *
+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for
+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell
+ * JPEG textbook (see REFERENCES section in file README).  The following code
+ * is based directly on figure 4-8 in P&M.
+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is
+ * possible to arrange the computation so that many of the multiplies are
+ * simple scalings of the final outputs.  These multiplies can then be
+ * folded into the multiplications or divisions by the JPEG quantization
+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
+ * to be done in the DCT itself.
+ * The primary disadvantage of this method is that with fixed-point math,
+ * accuracy is lost due to imprecise representation of the scaled
+ * quantization values.  The smaller the quantization table entry, the less
+ * precise the scaled value, so this implementation does worse with high-
+ * quality-setting files than with low-quality ones.

+ * This compromises accuracy slightly, but it lets us save a few shifts.
+ * More importantly, 16-bit arithmetic is then adequate (for 8-bit samples)

+ * This file provides an MS-DOS-compatible implementation of the system-
+ * dependent portion of the JPEG memory manager.  Temporary data can be
+ * stored in extended or expanded memory as well as in regular DOS files.
+ *
+ * If you use this file, you must be sure that NEED_FAR_POINTERS is defined
+ * if you compile in a small-data memory model; it should NOT be defined if
+ * you use a large-data memory model.  This file is not recommended if you
+ * are using a flat-memory-space 386 environment such as DJGCC or Watcom C.
+ * Also, this code will NOT work if struct fields are aligned on greater than
+ * 2-byte boundaries.
+ *
+ * Based on code contributed by Ge' Weijers.

+
+/*
+ * If you have both extended and expanded memory, you may want to change the
+ * order in which they are tried in jopen_backing_store.  On a 286 machine
+ * expanded memory is usually faster, since extended memory access involves
+ * an expensive protected-mode-and-back switch.  On 386 and better, extended
+ * memory is usually faster.  As distributed, the code tries extended memory
+ * first (what? not everyone has a 386? :-).
+ *
+ * You can disable use of extended/expanded memory entirely by altering these
+ * definitions or overriding them from the Makefile (eg, -DEMS_SUPPORTED=0).

+ * This file is part of the Independent JPEG Group's software.
+ * For conditions of distribution and use, see the accompanying README file.
+ *
+ * jmemmac.c provides an Apple Macintosh implementation of the system-
+ * dependent portion of the JPEG memory manager.
+ *
+ * If you use jmemmac.c, then you must define USE_MAC_MEMMGR in the
+ * JPEG_INTERNALS part of jconfig.h.
+ *
+ * jmemmac.c uses the Macintosh toolbox routines NewPtr and DisposePtr
+ * instead of malloc and free.  It accurately determines the amount of
+ * memory available by using CompactMem.  Notice that if left to its
+ * own devices, this code can chew up all available space in the
+ * application's zone, with the exception of the rather small "slop"
+ * factor computed in jpeg_mem_available().  The application can ensure
+ * that more space is left over by reducing max_memory_to_use.
+ *
+ * Large images are swapped to disk using temporary files and System 7.0+'s
+ * temporary folder functionality.
+ *
+ * Note that jmemmac.c depends on two features of MacOS that were first
+ * introduced in System 7: FindFolder and the FSSpec-based calls.
+ * If your application uses jmemmac.c and is run under System 6 or earlier,
+ * and the jpeg library decides it needs a temporary file, it will abort,
+ * printing error messages about requiring System 7.  (If no temporary files
+ * are created, it will run fine.)
+ *
+ * If you want to use jmemmac.c in an application that might be used with
+ * System 6 or earlier, then you should remove dependencies on FindFolder
+ * and the FSSpec calls.  You will need to replace FindFolder with some
+ * other mechanism for finding a place to put temporary files, and you
+ * should replace the FSSpec calls with their HFS equivalents:
+ *
+ *     FSpDelete     ->  HDelete
+ *     FSpGetFInfo   ->  HGetFInfo
+ *     FSpCreate     ->  HCreate
+ *     FSpOpenDF     ->  HOpen      *** Note: not HOpenDF ***
+ *     FSMakeFSSpec  ->  (fill in spec by hand.)
+ *
+ * (Use HOpen instead of HOpenDF.  HOpen is just a glue-interface to PBHOpen,
+ * which is on all HFS macs.  HOpenDF is a System 7 addition which avoids the
+ * ages-old problem of names starting with a period.)
+ *
+ * Contributed by Sam Bushell (jsam@iagu.on.net) and
+ * Dan Gildor (gyld@in-touch.com).

+ * This file contains the JPEG system-independent memory management
+ * routines.  This code is usable across a wide variety of machines; most
+ * of the system dependencies have been isolated in a separate file.
+ * The major functions provided here are:
+ *   * pool-based allocation and freeing of memory;
+ *   * policy decisions about how to divide available memory among the
+ *     virtual arrays;
+ *   * control logic for swapping virtual arrays between main memory and
+ *     backing storage.
+ * The separate system-dependent file provides the actual backing-storage
+ * access code, and it contains the policy decision about how much total
+ * main memory to use.
+ * This file is system-dependent in the sense that some of its functions
+ * are unnecessary in some systems.  For example, if there is enough virtual
+ * memory so that backing storage will never be used, much of the virtual
+ * array control logic could be removed.  (Of course, if you have that much
+ * memory then you shouldn't care about a little bit of unused code...)

+ * About virtual array management:
+ *
+ * The above "normal" array routines are only used to allocate strip buffers
+ * (as wide as the image, but just a few rows high).  Full-image-sized buffers
+ * are handled as "virtual" arrays.  The array is still accessed a strip at a
+ * time, but the memory manager must save the whole array for repeated
+ * accesses.  The intended implementation is that there is a strip buffer in
+ * memory (as high as is possible given the desired memory limit), plus a
+ * backing file that holds the rest of the array.
+ *
+ * The request_virt_array routines are told the total size of the image and
+ * the maximum number of rows that will be accessed at once.  The in-memory
+ * buffer must be at least as large as the maxaccess value.
+ *
+ * The request routines create control blocks but not the in-memory buffers.
+ * That is postponed until realize_virt_arrays is called.  At that time the
+ * total amount of space needed is known (approximately, anyway), so free
+ * memory can be divided up fairly.
+ *
+ * The access_virt_array routines are responsible for making a specific strip
+ * area accessible (after reading or writing the backing file, if necessary).
+ * Note that the access routines are told whether the caller intends to modify
+ * the accessed strip; during a read-only pass this saves having to rewrite
+ * data to disk.  The access routines are also responsible for pre-zeroing
+ * any newly accessed rows, if pre-zeroing was requested.
+ *
+ * In current usage, the access requests are usually for nonoverlapping
+ * strips; that is, successive access start_row numbers differ by exactly
+ * num_rows = maxaccess.  This means we can get good performance with simple
+ * buffer dump/reload logic, by making the in-memory buffer be a multiple
+ * of the access height; then there will never be accesses across bufferload
+ * boundaries.  The code will still work with overlapping access requests,
+ * but it doesn't handle bufferload overlaps very efficiently.

+ * The code as given is suitable for most Unix systems, and it is easily

+ *  1.  The temp file is created in the directory named by TEMP_DIRECTORY.
+ *      The default value is /usr/tmp, which is the conventional place for
+ *      creating large temp files on Unix.  On other systems you'll probably

+ *
+ *  2.  If you need to change the file name as well as its location,
+ *      you can override the TEMP_FILE_NAME macro.  (Note that this is
+ *      actually a printf format string; it must contain %s and %d.)
+ *      Few people should need to do this.
+ *
+ *  3.  mktemp() is used to ensure that multiple processes running
+ *      simultaneously won't select the same file names.  If your system
+ *      doesn't have mktemp(), define NO_MKTEMP to do it the hard way.
+ *      (If you don't have <errno.h>, also define NO_ERRNO_H.)
+ *
+ *  4.  You probably want to define NEED_SIGNAL_CATCHER so that cjpeg.c/djpeg.c
+ *      will cause the temp files to be removed if you stop the program early.

+.TH JPEGTRAN 1 "3 August 1997"
+.SH NAME
+jpegtran \- lossless transformation of JPEG files
+.SH SYNOPSIS
+.B jpegtran
+[
+.I options
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B jpegtran
+performs various useful transformations of JPEG files.
+It can translate the coded representation from one variant of JPEG to another,
+for example from baseline JPEG to progressive JPEG or vice versa.  It can also
+perform some rearrangements of the image data, for example turning an image
+from landscape to portrait format by rotation.
+.PP
+.B jpegtran
+works by rearranging the compressed data (DCT coefficients), without
+ever fully decoding the image.  Therefore, its transformations are lossless:
+there is no image degradation at all, which would not be true if you used
+.B djpeg
+followed by
+.B cjpeg
+to accomplish the same conversion.  But by the same token,
+.B jpegtran
+cannot perform lossy operations such as changing the image quality.
+.PP
+.B jpegtran
+reads the named JPEG/JFIF file, or the standard input if no file is
+named, and produces a JPEG/JFIF file on the standard output.
+.SH OPTIONS
+All switch names may be abbreviated; for example,
+.B \-optimize
+may be written
+.B \-opt
+or
+.BR \-o .
+Upper and lower case are equivalent.
+British spellings are also accepted (e.g.,
+.BR \-optimise ),
+though for brevity these are not mentioned below.
+.PP
+To specify the coded JPEG representation used in the output file,
+.B jpegtran
+accepts a subset of the switches recognized by
+.BR cjpeg :
+.TP
+.B \-optimize
+Perform optimization of entropy encoding parameters.
+.TP
+.B \-progressive
+Create progressive JPEG file.
+.TP
+.BI \-restart " N"
+Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is
+attached to the number.
+.TP
+.BI \-scans " file"
+Use the scan script given in the specified text file.
+.PP
+See
+.BR cjpeg (1)
+for more details about these switches.
+If you specify none of these switches, you get a plain baseline-JPEG output
+file.  The quality setting and so forth are determined by the input file.
+.PP
+The image can be losslessly transformed by giving one of these switches:
+.TP
+.B \-flip horizontal
+Mirror image horizontally (left-right).
+.TP
+.B \-flip vertical
+Mirror image vertically (top-bottom).
+.TP
+.B \-rotate 90
+Rotate image 90 degrees clockwise.
+.TP
+.B \-rotate 180
+Rotate image 180 degrees.
+.TP
+.B \-rotate 270
+Rotate image 270 degrees clockwise (or 90 ccw).
+.TP
+.B \-transpose
+Transpose image (across UL-to-LR axis).
+.TP
+.B \-transverse
+Transverse transpose (across UR-to-LL axis).
+.PP
+The transpose transformation has no restrictions regarding image dimensions.
+The other transformations operate rather oddly if the image dimensions are not
+a multiple of the iMCU size (usually 8 or 16 pixels), because they can only
+transform complete blocks of DCT coefficient data in the desired way.
+.PP
+.BR jpegtran 's
+default behavior when transforming an odd-size image is designed
+to preserve exact reversibility and mathematical consistency of the
+transformation set.  As stated, transpose is able to flip the entire image
+area.  Horizontal mirroring leaves any partial iMCU column at the right edge
+untouched, but is able to flip all rows of the image.  Similarly, vertical
+mirroring leaves any partial iMCU row at the bottom edge untouched, but is
+able to flip all columns.  The other transforms can be built up as sequences
+of transpose and flip operations; for consistency, their actions on edge
+pixels are defined to be the same as the end result of the corresponding
+transpose-and-flip sequence.
+.PP
+For practical use, you may prefer to discard any untransformable edge pixels
+rather than having a strange-looking strip along the right and/or bottom edges
+of a transformed image.  To do this, add the
+.B \-trim
+switch:
+.TP
+.B \-trim
+Drop non-transformable edge blocks.
+.PP
+Obviously, a transformation with
+.B \-trim
+is not reversible, so strictly speaking
+.B jpegtran
+with this switch is not lossless.  Also, the expected mathematical
+equivalences between the transformations no longer hold.  For example,
+.B \-rot 270 -trim
+trims only the bottom edge, but
+.B \-rot 90 -trim
+followed by
+.B \-rot 180 -trim
+trims both edges.
+.PP
+Another not-strictly-lossless transformation switch is:
+.TP
+.B \-grayscale
+Force grayscale output.
+.PP
+This option discards the chrominance channels if the input image is YCbCr
+(ie, a standard color JPEG), resulting in a grayscale JPEG file.  The
+luminance channel is preserved exactly, so this is a better method of reducing
+to grayscale than decompression, conversion, and recompression.  This switch
+is particularly handy for fixing a monochrome picture that was mistakenly
+encoded as a color JPEG.  (In such a case, the space savings from getting rid
+of the near-empty chroma channels won't be large; but the decoding time for
+a grayscale JPEG is substantially less than that for a color JPEG.)
+.PP
+.B jpegtran
+also recognizes these switches that control what to do with "extra" markers,
+such as comment blocks:
+.TP
+.B \-copy none
+Copy no extra markers from source file.  This setting suppresses all
+comments and other excess baggage present in the source file.
+.TP
+.B \-copy comments
+Copy only comment markers.  This setting copies comments from the source file,
+but discards any other inessential data.
+.TP
+.B \-copy all
+Copy all extra markers.  This setting preserves miscellaneous markers
+found in the source file, such as JFIF thumbnails and Photoshop settings.
+In some files these extra markers can be sizable.
+.PP
+The default behavior is
+.BR "\-copy comments" .
+(Note: in IJG releases v6 and v6a,
+.B jpegtran
+always did the equivalent of
+.BR "\-copy none" .)
+.PP
+Additional switches recognized by jpegtran are:
+.TP
+.BI \-maxmemory " N"
+Set limit for amount of memory to use in processing large images.  Value is
+in thousands of bytes, or millions of bytes if "M" is attached to the
+number.  For example,
+.B \-max 4m
+selects 4000000 bytes.  If more space is needed, temporary files will be used.
+.TP
+.BI \-outfile " name"
+Send output image to the named file, not to standard output.
+.TP
+.B \-verbose
+Enable debug printout.  More
+.BR \-v 's
+give more output.  Also, version information is printed at startup.
+.TP
+.B \-debug
+Same as
+.BR \-verbose .
+.SH EXAMPLES
+.LP
+This example converts a baseline JPEG file to progressive form:
+.IP
+.B jpegtran \-progressive
+.I foo.jpg
+.B >
+.I fooprog.jpg
+.PP
+This example rotates an image 90 degrees clockwise, discarding any
+unrotatable edge pixels:
+.IP
+.B jpegtran \-rot 90 -trim
+.I foo.jpg
+.B >
+.I foo90.jpg
+.SH ENVIRONMENT
+.TP
+.B JPEGMEM
+If this environment variable is set, its value is the default memory limit.
+The value is specified as described for the
+.B \-maxmemory
+switch.
+.B JPEGMEM
+overrides the default value specified when the program was compiled, and
+itself is overridden by an explicit
+.BR \-maxmemory .

+.SH AUTHOR
+Independent JPEG Group
+.SH BUGS
+Arithmetic coding is not supported for legal reasons.
+.PP
+The transform options can't transform odd-size images perfectly.  Use
+.B \-trim
+if you don't like the results without it.
+.PP
+The entire image is read into memory and then written out again, even in
+cases where this isn't really necessary.  Expect swapping on large images,
+especially when using the more complex transform options.

+/*
+ * The main purpose of 1-pass quantization is to provide a fast, if not very
+ * high quality, colormapped output capability.  A 2-pass quantizer usually
+ * gives better visual quality; however, for quantized grayscale output this
+ * quantizer is perfectly adequate.  Dithering is highly recommended with this
+ * quantizer, though you can turn it off if you really want to.
+ *
+ * In 1-pass quantization the colormap must be chosen in advance of seeing the
+ * image.  We use a map consisting of all combinations of Ncolors[i] color
+ * values for the i'th component.  The Ncolors[] values are chosen so that
+ * their product, the total number of colors, is no more than that requested.
+ * (In most cases, the product will be somewhat less.)
+ *
+ * Since the colormap is orthogonal, the representative value for each color
+ * component can be determined without considering the other components;
+ * then these indexes can be combined into a colormap index by a standard
+ * N-dimensional-array-subscript calculation.  Most of the arithmetic involved
+ * can be precalculated and stored in the lookup table colorindex[].
+ * colorindex[i][j] maps pixel value j in component i to the nearest
+ * representative value (grid plane) for that component; this index is
+ * multiplied by the array stride for component i, so that the
+ * index of the colormap entry closest to a given pixel value is just
+ *    sum( colorindex[component-number][pixel-component-value] )
+ * Aside from being fast, this scheme allows for variable spacing between
+ * representative values with no additional lookup cost.
+ *
+ * If gamma correction has been applied in color conversion, it might be wise
+ * to adjust the color grid spacing so that the representative colors are
+ * equidistant in linear space.  At this writing, gamma correction is not
+ * implemented by jdcolor, so nothing is done here.

+/* Declarations for ordered dithering.
+ *
+ * We use a standard 16x16 ordered dither array.  The basic concept of ordered
+ * dithering is described in many references, for instance Dale Schumacher's
+ * chapter II.2 of Graphics Gems II (James Arvo, ed. Academic Press, 1991).
+ * In place of Schumacher's comparisons against a "threshold" value, we add a
+ * "dither" value to the input pixel and then round the result to the nearest
+ * output value.  The dither value is equivalent to (0.5 - threshold) times
+ * the distance between output values.  For ordered dithering, we assume that
+ * the output colors are equally spaced; if not, results will probably be
+ * worse, since the dither may be too much or too little at a given point.
+ *
+ * The normal calculation would be to form pixel value + dither, range-limit
+ * this to 0..MAXJSAMPLE, and then index into the colorindex table as usual.
+ * We can skip the separate range-limiting step by extending the colorindex
+ * table in both directions.

+ * This module implements the well-known Heckbert paradigm for color
+ * quantization.  Most of the ideas used here can be traced back to
+ * Heckbert's seminal paper
+ *   Heckbert, Paul.  "Color Image Quantization for Frame Buffer Display",
+ *   Proc. SIGGRAPH '82, Computer Graphics v.16 #3 (July 1982), pp 297-304.
+ *
+ * In the first pass over the image, we accumulate a histogram showing the
+ * usage count of each possible color.  To keep the histogram to a reasonable
+ * size, we reduce the precision of the input; typical practice is to retain
+ * 5 or 6 bits per color, so that 8 or 4 different input values are counted
+ * in the same histogram cell.
+ *
+ * Next, the color-selection step begins with a box representing the whole
+ * color space, and repeatedly splits the "largest" remaining box until we
+ * have as many boxes as desired colors.  Then the mean color in each
+ * remaining box becomes one of the possible output colors.
+ * 
+ * The second pass over the image maps each input pixel to the closest output
+ * color (optionally after applying a Floyd-Steinberg dithering correction).
+ * This mapping is logically trivial, but making it go fast enough requires
+ * considerable care.
+ *
+ * Heckbert-style quantizers vary a good deal in their policies for choosing
+ * the "largest" box and deciding where to cut it.  The particular policies
+ * used here have proved out well in experimental comparisons, but better ones
+ * may yet be found.
+ *
+ * In earlier versions of the IJG code, this module quantized in YCbCr color
+ * space, processing the raw upsampled data without a color conversion step.
+ * This allowed the color conversion math to be done only once per colormap
+ * entry, not once per pixel.  However, that optimization precluded other
+ * useful optimizations (such as merging color conversion with upsampling)
+ * and it also interfered with desired capabilities such as quantizing to an
+ * externally-supplied colormap.  We have therefore abandoned that approach.
+ * The present code works in the post-conversion color space, typically RGB.
+ *
+ * To improve the visual quality of the results, we actually work in scaled
+ * RGB space, giving G distances more weight than R, and R in turn more than
+ * B.  To do everything in integer math, we must use integer scale factors.
+ * The 2/3/1 scale factors used here correspond loosely to the relative
+ * weights of the colors in the NTSC grayscale equation.
+ * If you want to use this code to quantize a non-RGB color space, you'll
+ * probably need to change these scale factors.

+ * you'll get compile errors until you extend this logic.  In that case
+ * you'll probably want to tweak the histogram sizes too.

+ * First we have the histogram data structure and routines for creating it.
+ *
+ * The number of bits of precision can be adjusted by changing these symbols.
+ * We recommend keeping 6 bits for G and 5 each for R and B.
+ * If you have plenty of memory and cycles, 6 bits all around gives marginally
+ * better results; if you are short of memory, 5 bits all around will save
+ * some space but degrade the results.
+ * To maintain a fully accurate histogram, we'd need to allocate a "long"
+ * (preferably unsigned long) for each cell.  In practice this is overkill;
+ * we can get by with 16 bits per cell.  Few of the cell counts will overflow,
+ * and clamping those that do overflow to the maximum value will give close-
+ * enough results.  This reduces the recommended histogram size from 256Kb
+ * to 128Kb, which is a useful savings on PC-class machines.
+ * (In the second pass the histogram space is re-used for pixel mapping data;
+ * in that capacity, each cell must be able to store zero to the number of
+ * desired colors.  16 bits/cell is plenty for that too.)
+ * Since the JPEG code is intended to run in small memory model on 80x86
+ * machines, we can't just allocate the histogram in one chunk.  Instead
+ * of a true 3-D array, we use a row of pointers to 2-D arrays.  Each
+ * pointer corresponds to a C0 value (typically 2^5 = 32 pointers) and
+ * each 2-D array has 2^6*2^5 = 2048 or 2^6*2^6 = 4096 entries.  Note that
+ * on 80x86 machines, the pointer row is in near memory but the actual

+ * These routines are concerned with the time-critical task of mapping input
+ * colors to the nearest color in the selected colormap.
+ *
+ * We re-use the histogram space as an "inverse color map", essentially a
+ * cache for the results of nearest-color searches.  All colors within a
+ * histogram cell will be mapped to the same colormap entry, namely the one
+ * closest to the cell's center.  This may not be quite the closest entry to
+ * the actual input color, but it's almost as good.  A zero in the cache
+ * indicates we haven't found the nearest color for that cell yet; the array
+ * is cleared to zeroes before starting the mapping pass.  When we find the
+ * nearest color for a cell, its colormap index plus one is recorded in the
+ * cache for future use.  The pass2 scanning routines call fill_inverse_cmap
+ * when they need to use an unfilled entry in the cache.
+ *
+ * Our method of efficiently finding nearest colors is based on the "locally
+ * sorted search" idea described by Heckbert and on the incremental distance
+ * calculation described by Spencer W. Thomas in chapter III.1 of Graphics
+ * Gems II (James Arvo, ed.  Academic Press, 1991).  Thomas points out that
+ * the distances from a given colormap entry to each cell of the histogram can
+ * be computed quickly using an incremental method: the differences between
+ * distances to adjacent cells themselves differ by a constant.  This allows a
+ * fairly fast implementation of the "brute force" approach of computing the
+ * distance from every colormap entry to every histogram cell.  Unfortunately,
+ * it needs a work array to hold the best-distance-so-far for each histogram
+ * cell (because the inner loop has to be over cells, not colormap entries).
+ * The work array elements have to be INT32s, so the work array would need
+ * 256Kb at our recommended precision.  This is not feasible in DOS machines.
+ *
+ * To get around these problems, we apply Thomas' method to compute the
+ * nearest colors for only the cells within a small subbox of the histogram.
+ * The work array need be only as big as the subbox, so the memory usage
+ * problem is solved.  Furthermore, we need not fill subboxes that are never
+ * referenced in pass2; many images use only part of the color gamut, so a
+ * fair amount of work is saved.  An additional advantage of this
+ * approach is that we can apply Heckbert's locality criterion to quickly
+ * eliminate colormap entries that are far away from the subbox; typically
+ * three-fourths of the colormap entries are rejected by Heckbert's criterion,
+ * and we need not compute their distances to individual cells in the subbox.
+ * The speed of this approach is heavily influenced by the subbox size: too
+ * small means too much overhead, too big loses because Heckbert's criterion
+ * can't eliminate as many colormap entries.  Empirically the best subbox
+ * size seems to be about 1/512th of the histogram (1/8th in each direction).
+ *
+ * Thomas' article also describes a refined method which is asymptotically
+ * faster than the brute-force method, but it is also far more complex and
+ * cannot efficiently be applied to small subboxes.  It is therefore not
+ * useful for programs intended to be portable to DOS machines.  On machines
+ * with plenty of memory, filling the whole histogram in one shot with Thomas'
+ * refined method might be faster than the present code --- but then again,
+ * it might not be any faster, and it's certainly more complicated.

+USING THE IJG JPEG LIBRARY
+
+Copyright (C) 1994-1998, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+This file describes how to use the IJG JPEG library within an application
+program.  Read it if you want to write a program that uses the library.
+
+The file example.c provides heavily commented skeleton code for calling the
+JPEG library.  Also see jpeglib.h (the include file to be used by application
+programs) for full details about data structures and function parameter lists.
+The library source code, of course, is the ultimate reference.
+
+Note that there have been *major* changes from the application interface
+presented by IJG version 4 and earlier versions.  The old design had several
+inherent limitations, and it had accumulated a lot of cruft as we added
+features while trying to minimize application-interface changes.  We have
+sacrificed backward compatibility in the version 5 rewrite, but we think the
+improvements justify this.

+
+OVERVIEW
+========
+
+Functions provided by the library
+---------------------------------
+
+The IJG JPEG library provides C code to read and write JPEG-compressed image
+files.  The surrounding application program receives or supplies image data a
+scanline at a time, using a straightforward uncompressed image format.  All
+details of color conversion and other preprocessing/postprocessing can be
+handled by the library.
+
+The library includes a substantial amount of code that is not covered by the
+JPEG standard but is necessary for typical applications of JPEG.  These
+functions preprocess the image before JPEG compression or postprocess it after
+decompression.  They include colorspace conversion, downsampling/upsampling,
+and color quantization.  The application indirectly selects use of this code
+by specifying the format in which it wishes to supply or receive image data.
+For example, if colormapped output is requested, then the decompression
+library automatically invokes color quantization.
+
+A wide range of quality vs. speed tradeoffs are possible in JPEG processing,
+and even more so in decompression postprocessing.  The decompression library
+provides multiple implementations that cover most of the useful tradeoffs,
+ranging from very-high-quality down to fast-preview operation.  On the
+compression side we have generally not provided low-quality choices, since
+compression is normally less time-critical.  It should be understood that the
+low-quality modes may not meet the JPEG standard's accuracy requirements;
+nonetheless, they are useful for viewers.
+
+A word about functions *not* provided by the library.  We handle a subset of
+the ISO JPEG standard; most baseline, extended-sequential, and progressive
+JPEG processes are supported.  (Our subset includes all features now in common
+use.)  Unsupported ISO options include:
+	* Hierarchical storage
+	* Lossless JPEG
+	* Arithmetic entropy coding (unsupported for legal reasons)
+	* DNL marker
+	* Nonintegral subsampling ratios
+We support both 8- and 12-bit data precision, but this is a compile-time
+choice rather than a run-time choice; hence it is difficult to use both
+precisions in a single application.
+
+By itself, the library handles only interchange JPEG datastreams --- in
+particular the widely used JFIF file format.  The library can be used by
+surrounding code to process interchange or abbreviated JPEG datastreams that
+are embedded in more complex file formats.  (For example, this library is
+used by the free LIBTIFF library to support JPEG compression in TIFF.)
+
+
+Outline of typical usage
+------------------------
+
+The rough outline of a JPEG compression operation is:
+
+	Allocate and initialize a JPEG compression object
+	Specify the destination for the compressed data (eg, a file)
+	Set parameters for compression, including image size & colorspace
+	jpeg_start_compress(...);
+	while (scan lines remain to be written)
+		jpeg_write_scanlines(...);
+	jpeg_finish_compress(...);
+	Release the JPEG compression object
+
+A JPEG compression object holds parameters and working state for the JPEG
+library.  We make creation/destruction of the object separate from starting
+or finishing compression of an image; the same object can be re-used for a
+series of image compression operations.  This makes it easy to re-use the
+same parameter settings for a sequence of images.  Re-use of a JPEG object
+also has important implications for processing abbreviated JPEG datastreams,
+as discussed later.
+
+The image data to be compressed is supplied to jpeg_write_scanlines() from
+in-memory buffers.  If the application is doing file-to-file compression,
+reading image data from the source file is the application's responsibility.
+The library emits compressed data by calling a "data destination manager",
+which typically will write the data into a file; but the application can
+provide its own destination manager to do something else.
+
+Similarly, the rough outline of a JPEG decompression operation is:
+
+	Allocate and initialize a JPEG decompression object
+	Specify the source of the compressed data (eg, a file)
+	Call jpeg_read_header() to obtain image info
+	Set parameters for decompression
+	jpeg_start_decompress(...);
+	while (scan lines remain to be read)
+		jpeg_read_scanlines(...);
+	jpeg_finish_decompress(...);
+	Release the JPEG decompression object
+
+This is comparable to the compression outline except that reading the
+datastream header is a separate step.  This is helpful because information
+about the image's size, colorspace, etc is available when the application
+selects decompression parameters.  For example, the application can choose an
+output scaling ratio that will fit the image into the available screen size.
+
+The decompression library obtains compressed data by calling a data source
+manager, which typically will read the data from a file; but other behaviors
+can be obtained with a custom source manager.  Decompressed data is delivered
+into in-memory buffers passed to jpeg_read_scanlines().
+
+It is possible to abort an incomplete compression or decompression operation
+by calling jpeg_abort(); or, if you do not need to retain the JPEG object,
+simply release it by calling jpeg_destroy().
+
+JPEG compression and decompression objects are two separate struct types.
+However, they share some common fields, and certain routines such as
+jpeg_destroy() can work on either type of object.
+
+The JPEG library has no static variables: all state is in the compression
+or decompression object.  Therefore it is possible to process multiple
+compression and decompression operations concurrently, using multiple JPEG
+objects.
+
+Both compression and decompression can be done in an incremental memory-to-
+memory fashion, if suitable source/destination managers are used.  See the
+section on "I/O suspension" for more details.
+
+
+BASIC LIBRARY USAGE
+===================
+
+Data formats
+------------
+
+Before diving into procedural details, it is helpful to understand the
+image data format that the JPEG library expects or returns.
+
+The standard input image format is a rectangular array of pixels, with each
+pixel having the same number of "component" or "sample" values (color
+channels).  You must specify how many components there are and the colorspace
+interpretation of the components.  Most applications will use RGB data
+(three components per pixel) or grayscale data (one component per pixel).
+PLEASE NOTE THAT RGB DATA IS THREE SAMPLES PER PIXEL, GRAYSCALE ONLY ONE.
+A remarkable number of people manage to miss this, only to find that their
+programs don't work with grayscale JPEG files.
+
+There is no provision for colormapped input.  JPEG files are always full-color
+or full grayscale (or sometimes another colorspace such as CMYK).  You can
+feed in a colormapped image by expanding it to full-color format.  However
+JPEG often doesn't work very well with source data that has been colormapped,
+because of dithering noise.  This is discussed in more detail in the JPEG FAQ
+and the other references mentioned in the README file.
+
+Pixels are stored by scanlines, with each scanline running from left to
+right.  The component values for each pixel are adjacent in the row; for
+example, R,G,B,R,G,B,R,G,B,... for 24-bit RGB color.  Each scanline is an
+array of data type JSAMPLE --- which is typically "unsigned char", unless
+you've changed jmorecfg.h.  (You can also change the RGB pixel layout, say
+to B,G,R order, by modifying jmorecfg.h.  But see the restrictions listed in
+that file before doing so.)
+
+A 2-D array of pixels is formed by making a list of pointers to the starts of
+scanlines; so the scanlines need not be physically adjacent in memory.  Even
+if you process just one scanline at a time, you must make a one-element
+pointer array to conform to this structure.  Pointers to JSAMPLE rows are of
+type JSAMPROW, and the pointer to the pointer array is of type JSAMPARRAY.
+
+The library accepts or supplies one or more complete scanlines per call.
+It is not possible to process part of a row at a time.  Scanlines are always
+processed top-to-bottom.  You can process an entire image in one call if you
+have it all in memory, but usually it's simplest to process one scanline at
+a time.
+
+For best results, source data values should have the precision specified by
+BITS_IN_JSAMPLE (normally 8 bits).  For instance, if you choose to compress
+data that's only 6 bits/channel, you should left-justify each value in a
+byte before passing it to the compressor.  If you need to compress data
+that has more than 8 bits/channel, compile with BITS_IN_JSAMPLE = 12.
+(See "Library compile-time options", later.)
+
+
+The data format returned by the decompressor is the same in all details,
+except that colormapped output is supported.  (Again, a JPEG file is never
+colormapped.  But you can ask the decompressor to perform on-the-fly color
+quantization to deliver colormapped output.)  If you request colormapped
+output then the returned data array contains a single JSAMPLE per pixel;
+its value is an index into a color map.  The color map is represented as
+a 2-D JSAMPARRAY in which each row holds the values of one color component,
+that is, colormap[i][j] is the value of the i'th color component for pixel
+value (map index) j.  Note that since the colormap indexes are stored in
+JSAMPLEs, the maximum number of colors is limited by the size of JSAMPLE
+(ie, at most 256 colors for an 8-bit JPEG library).
+
+
+Compression details
+-------------------
+
+Here we revisit the JPEG compression outline given in the overview.
+
+1. Allocate and initialize a JPEG compression object.
+
+A JPEG compression object is a "struct jpeg_compress_struct".  (It also has
+a bunch of subsidiary structures which are allocated via malloc(), but the
+application doesn't control those directly.)  This struct can be just a local
+variable in the calling routine, if a single routine is going to execute the
+whole JPEG compression sequence.  Otherwise it can be static or allocated
+from malloc().
+
+You will also need a structure representing a JPEG error handler.  The part
+of this that the library cares about is a "struct jpeg_error_mgr".  If you
+are providing your own error handler, you'll typically want to embed the
+jpeg_error_mgr struct in a larger structure; this is discussed later under
+"Error handling".  For now we'll assume you are just using the default error
+handler.  The default error handler will print JPEG error/warning messages
+on stderr, and it will call exit() if a fatal error occurs.
+
+You must initialize the error handler structure, store a pointer to it into
+the JPEG object's "err" field, and then call jpeg_create_compress() to
+initialize the rest of the JPEG object.
+
+Typical code for this step, if you are using the default error handler, is
+
+	struct jpeg_compress_struct cinfo;
+	struct jpeg_error_mgr jerr;
+	...
+	cinfo.err = jpeg_std_error(&jerr);
+	jpeg_create_compress(&cinfo);
+
+jpeg_create_compress allocates a small amount of memory, so it could fail
+if you are out of memory.  In that case it will exit via the error handler;
+that's why the error handler must be initialized first.
+
+
+2. Specify the destination for the compressed data (eg, a file).
+
+As previously mentioned, the JPEG library delivers compressed data to a
+"data destination" module.  The library includes one data destination
+module which knows how to write to a stdio stream.  You can use your own
+destination module if you want to do something else, as discussed later.
+
+If you use the standard destination module, you must open the target stdio
+stream beforehand.  Typical code for this step looks like:
+
+	FILE * outfile;
+	...
+	if ((outfile = fopen(filename, "wb")) == NULL) {
+	    fprintf(stderr, "can't open %s\n", filename);
+	    exit(1);
+	}
+	jpeg_stdio_dest(&cinfo, outfile);
+
+where the last line invokes the standard destination module.
+
+WARNING: it is critical that the binary compressed data be delivered to the
+output file unchanged.  On non-Unix systems the stdio library may perform
+newline translation or otherwise corrupt binary data.  To suppress this
+behavior, you may need to use a "b" option to fopen (as shown above), or use
+setmode() or another routine to put the stdio stream in binary mode.  See
+cjpeg.c and djpeg.c for code that has been found to work on many systems.
+
+You can select the data destination after setting other parameters (step 3),
+if that's more convenient.  You may not change the destination between
+calling jpeg_start_compress() and jpeg_finish_compress().
+
+
+3. Set parameters for compression, including image size & colorspace.
+
+You must supply information about the source image by setting the following
+fields in the JPEG object (cinfo structure):
+
+	image_width		Width of image, in pixels
+	image_height		Height of image, in pixels
+	input_components	Number of color channels (samples per pixel)
+	in_color_space		Color space of source image
+
+The image dimensions are, hopefully, obvious.  JPEG supports image dimensions
+of 1 to 64K pixels in either direction.  The input color space is typically
+RGB or grayscale, and input_components is 3 or 1 accordingly.  (See "Special
+color spaces", later, for more info.)  The in_color_space field must be
+assigned one of the J_COLOR_SPACE enum constants, typically JCS_RGB or
+JCS_GRAYSCALE.
+
+JPEG has a large number of compression parameters that determine how the
+image is encoded.  Most applications don't need or want to know about all
+these parameters.  You can set all the parameters to reasonable defaults by
+calling jpeg_set_defaults(); then, if there are particular values you want
+to change, you can do so after that.  The "Compression parameter selection"
+section tells about all the parameters.
+
+You must set in_color_space correctly before calling jpeg_set_defaults(),
+because the defaults depend on the source image colorspace.  However the
+other three source image parameters need not be valid until you call
+jpeg_start_compress().  There's no harm in calling jpeg_set_defaults() more
+than once, if that happens to be convenient.
+
+Typical code for a 24-bit RGB source image is
+
+	cinfo.image_width = Width; 	/* image width and height, in pixels */
+	cinfo.image_height = Height;
+	cinfo.input_components = 3;	/* # of color components per pixel */
+	cinfo.in_color_space = JCS_RGB; /* colorspace of input image */
+
+	jpeg_set_defaults(&cinfo);
+	/* Make optional parameter settings here */
+
+
+4. jpeg_start_compress(...);
+
+After you have established the data destination and set all the necessary
+source image info and other parameters, call jpeg_start_compress() to begin
+a compression cycle.  This will initialize internal state, allocate working
+storage, and emit the first few bytes of the JPEG datastream header.
+
+Typical code:
+
+	jpeg_start_compress(&cinfo, TRUE);
+
+The "TRUE" parameter ensures that a complete JPEG interchange datastream
+will be written.  This is appropriate in most cases.  If you think you might
+want to use an abbreviated datastream, read the section on abbreviated
+datastreams, below.
+
+Once you have called jpeg_start_compress(), you may not alter any JPEG
+parameters or other fields of the JPEG object until you have completed
+the compression cycle.
+
+
+5. while (scan lines remain to be written)
+	jpeg_write_scanlines(...);
+
+Now write all the required image data by calling jpeg_write_scanlines()
+one or more times.  You can pass one or more scanlines in each call, up
+to the total image height.  In most applications it is convenient to pass
+just one or a few scanlines at a time.  The expected format for the passed
+data is discussed under "Data formats", above.
+
+Image data should be written in top-to-bottom scanline order.  The JPEG spec
+contains some weasel wording about how top and bottom are application-defined
+terms (a curious interpretation of the English language...) but if you want
+your files to be compatible with everyone else's, you WILL use top-to-bottom
+order.  If the source data must be read in bottom-to-top order, you can use
+the JPEG library's virtual array mechanism to invert the data efficiently.
+Examples of this can be found in the sample application cjpeg.
+
+The library maintains a count of the number of scanlines written so far
+in the next_scanline field of the JPEG object.  Usually you can just use
+this variable as the loop counter, so that the loop test looks like
+"while (cinfo.next_scanline < cinfo.image_height)".
+
+Code for this step depends heavily on the way that you store the source data.
+example.c shows the following code for the case of a full-size 2-D source
+array containing 3-byte RGB pixels:
+
+	JSAMPROW row_pointer[1];	/* pointer to a single row */
+	int row_stride;			/* physical row width in buffer */
+
+	row_stride = image_width * 3;	/* JSAMPLEs per row in image_buffer */
+
+	while (cinfo.next_scanline < cinfo.image_height) {
+	    row_pointer[0] = & image_buffer[cinfo.next_scanline * row_stride];
+	    jpeg_write_scanlines(&cinfo, row_pointer, 1);
+	}
+
+jpeg_write_scanlines() returns the number of scanlines actually written.
+This will normally be equal to the number passed in, so you can usually
+ignore the return value.  It is different in just two cases:
+  * If you try to write more scanlines than the declared image height,
+    the additional scanlines are ignored.
+  * If you use a suspending data destination manager, output buffer overrun
+    will cause the compressor to return before accepting all the passed lines.
+    This feature is discussed under "I/O suspension", below.  The normal
+    stdio destination manager will NOT cause this to happen.
+In any case, the return value is the same as the change in the value of
+next_scanline.
+
+
+6. jpeg_finish_compress(...);
+
+After all the image data has been written, call jpeg_finish_compress() to
+complete the compression cycle.  This step is ESSENTIAL to ensure that the
+last bufferload of data is written to the data destination.
+jpeg_finish_compress() also releases working memory associated with the JPEG
+object.
+
+Typical code:
+
+	jpeg_finish_compress(&cinfo);
+
+If using the stdio destination manager, don't forget to close the output
+stdio stream (if necessary) afterwards.
+
+If you have requested a multi-pass operating mode, such as Huffman code
+optimization, jpeg_finish_compress() will perform the additional passes using
+data buffered by the first pass.  In this case jpeg_finish_compress() may take
+quite a while to complete.  With the default compression parameters, this will
+not happen.
+
+It is an error to call jpeg_finish_compress() before writing the necessary
+total number of scanlines.  If you wish to abort compression, call
+jpeg_abort() as discussed below.
+
+After completing a compression cycle, you may dispose of the JPEG object
+as discussed next, or you may use it to compress another image.  In that case
+return to step 2, 3, or 4 as appropriate.  If you do not change the
+destination manager, the new datastream will be written to the same target.
+If you do not change any JPEG parameters, the new datastream will be written
+with the same parameters as before.  Note that you can change the input image
+dimensions freely between cycles, but if you change the input colorspace, you
+should call jpeg_set_defaults() to adjust for the new colorspace; and then
+you'll need to repeat all of step 3.
+
+
+7. Release the JPEG compression object.
+
+When you are done with a JPEG compression object, destroy it by calling
+jpeg_destroy_compress().  This will free all subsidiary memory (regardless of
+the previous state of the object).  Or you can call jpeg_destroy(), which
+works for either compression or decompression objects --- this may be more
+convenient if you are sharing code between compression and decompression
+cases.  (Actually, these routines are equivalent except for the declared type
+of the passed pointer.  To avoid gripes from ANSI C compilers, jpeg_destroy()
+should be passed a j_common_ptr.)
+
+If you allocated the jpeg_compress_struct structure from malloc(), freeing
+it is your responsibility --- jpeg_destroy() won't.  Ditto for the error
+handler structure.
+
+Typical code:
+
+	jpeg_destroy_compress(&cinfo);
+
+
+8. Aborting.
+
+If you decide to abort a compression cycle before finishing, you can clean up
+in either of two ways:
+
+* If you don't need the JPEG object any more, just call
+  jpeg_destroy_compress() or jpeg_destroy() to release memory.  This is
+  legitimate at any point after calling jpeg_create_compress() --- in fact,
+  it's safe even if jpeg_create_compress() fails.
+
+* If you want to re-use the JPEG object, call jpeg_abort_compress(), or call
+  jpeg_abort() which works on both compression and decompression objects.
+  This will return the object to an idle state, releasing any working memory.
+  jpeg_abort() is allowed at any time after successful object creation.
+
+Note that cleaning up the data destination, if required, is your
+responsibility; neither of these routines will call term_destination().
+(See "Compressed data handling", below, for more about that.)
+
+jpeg_destroy() and jpeg_abort() are the only safe calls to make on a JPEG
+object that has reported an error by calling error_exit (see "Error handling"
+for more info).  The internal state of such an object is likely to be out of
+whack.  Either of these two routines will return the object to a known state.
+
+
+Decompression details
+---------------------
+
+Here we revisit the JPEG decompression outline given in the overview.
+
+1. Allocate and initialize a JPEG decompression object.
+
+This is just like initialization for compression, as discussed above,
+except that the object is a "struct jpeg_decompress_struct" and you
+call jpeg_create_decompress().  Error handling is exactly the same.
+
+Typical code:
+
+	struct jpeg_decompress_struct cinfo;
+	struct jpeg_error_mgr jerr;
+	...
+	cinfo.err = jpeg_std_error(&jerr);
+	jpeg_create_decompress(&cinfo);
+
+(Both here and in the IJG code, we usually use variable name "cinfo" for
+both compression and decompression objects.)
+
+
+2. Specify the source of the compressed data (eg, a file).
+
+As previously mentioned, the JPEG library reads compressed data from a "data
+source" module.  The library includes one data source module which knows how
+to read from a stdio stream.  You can use your own source module if you want
+to do something else, as discussed later.
+
+If you use the standard source module, you must open the source stdio stream
+beforehand.  Typical code for this step looks like:
+
+	FILE * infile;
+	...
+	if ((infile = fopen(filename, "rb")) == NULL) {
+	    fprintf(stderr, "can't open %s\n", filename);
+	    exit(1);
+	}
+	jpeg_stdio_src(&cinfo, infile);
+
+where the last line invokes the standard source module.
+
+WARNING: it is critical that the binary compressed data be read unchanged.
+On non-Unix systems the stdio library may perform newline translation or
+otherwise corrupt binary data.  To suppress this behavior, you may need to use
+a "b" option to fopen (as shown above), or use setmode() or another routine to
+put the stdio stream in binary mode.  See cjpeg.c and djpeg.c for code that
+has been found to work on many systems.
+
+You may not change the data source between calling jpeg_read_header() and
+jpeg_finish_decompress().  If you wish to read a series of JPEG images from
+a single source file, you should repeat the jpeg_read_header() to
+jpeg_finish_decompress() sequence without reinitializing either the JPEG
+object or the data source module; this prevents buffered input data from
+being discarded.
+
+
+3. Call jpeg_read_header() to obtain image info.
+
+Typical code for this step is just
+
+	jpeg_read_header(&cinfo, TRUE);
+
+This will read the source datastream header markers, up to the beginning
+of the compressed data proper.  On return, the image dimensions and other
+info have been stored in the JPEG object.  The application may wish to
+consult this information before selecting decompression parameters.
+
+More complex code is necessary if
+  * A suspending data source is used --- in that case jpeg_read_header()
+    may return before it has read all the header data.  See "I/O suspension",
+    below.  The normal stdio source manager will NOT cause this to happen.
+  * Abbreviated JPEG files are to be processed --- see the section on
+    abbreviated datastreams.  Standard applications that deal only in
+    interchange JPEG files need not be concerned with this case either.
+
+It is permissible to stop at this point if you just wanted to find out the
+image dimensions and other header info for a JPEG file.  In that case,
+call jpeg_destroy() when you are done with the JPEG object, or call
+jpeg_abort() to return it to an idle state before selecting a new data
+source and reading another header.
+
+
+4. Set parameters for decompression.
+
+jpeg_read_header() sets appropriate default decompression parameters based on
+the properties of the image (in particular, its colorspace).  However, you
+may well want to alter these defaults before beginning the decompression.
+For example, the default is to produce full color output from a color file.
+If you want colormapped output you must ask for it.  Other options allow the
+returned image to be scaled and allow various speed/quality tradeoffs to be
+selected.  "Decompression parameter selection", below, gives details.
+
+If the defaults are appropriate, nothing need be done at this step.
+
+Note that all default values are set by each call to jpeg_read_header().
+If you reuse a decompression object, you cannot expect your parameter
+settings to be preserved across cycles, as you can for compression.
+You must set desired parameter values each time.
+
+
+5. jpeg_start_decompress(...);
+
+Once the parameter values are satisfactory, call jpeg_start_decompress() to
+begin decompression.  This will initialize internal state, allocate working
+memory, and prepare for returning data.
+
+Typical code is just
+
+	jpeg_start_decompress(&cinfo);
+
+If you have requested a multi-pass operating mode, such as 2-pass color
+quantization, jpeg_start_decompress() will do everything needed before data
+output can begin.  In this case jpeg_start_decompress() may take quite a while
+to complete.  With a single-scan (non progressive) JPEG file and default
+decompression parameters, this will not happen; jpeg_start_decompress() will
+return quickly.
+
+After this call, the final output image dimensions, including any requested
+scaling, are available in the JPEG object; so is the selected colormap, if
+colormapped output has been requested.  Useful fields include
+
+	output_width		image width and height, as scaled
+	output_height
+	out_color_components	# of color components in out_color_space
+	output_components	# of color components returned per pixel
+	colormap		the selected colormap, if any
+	actual_number_of_colors		number of entries in colormap
+
+output_components is 1 (a colormap index) when quantizing colors; otherwise it
+equals out_color_components.  It is the number of JSAMPLE values that will be
+emitted per pixel in the output arrays.
+
+Typically you will need to allocate data buffers to hold the incoming image.
+You will need output_width * output_components JSAMPLEs per scanline in your
+output buffer, and a total of output_height scanlines will be returned.
+
+Note: if you are using the JPEG library's internal memory manager to allocate
+data buffers (as djpeg does), then the manager's protocol requires that you
+request large buffers *before* calling jpeg_start_decompress().  This is a
+little tricky since the output_XXX fields are not normally valid then.  You
+can make them valid by calling jpeg_calc_output_dimensions() after setting the
+relevant parameters (scaling, output color space, and quantization flag).
+
+
+6. while (scan lines remain to be read)
+	jpeg_read_scanlines(...);
+
+Now you can read the decompressed image data by calling jpeg_read_scanlines()
+one or more times.  At each call, you pass in the maximum number of scanlines
+to be read (ie, the height of your working buffer); jpeg_read_scanlines()
+will return up to that many lines.  The return value is the number of lines
+actually read.  The format of the returned data is discussed under "Data
+formats", above.  Don't forget that grayscale and color JPEGs will return
+different data formats!
+
+Image data is returned in top-to-bottom scanline order.  If you must write
+out the image in bottom-to-top order, you can use the JPEG library's virtual
+array mechanism to invert the data efficiently.  Examples of this can be
+found in the sample application djpeg.
+
+The library maintains a count of the number of scanlines returned so far
+in the output_scanline field of the JPEG object.  Usually you can just use
+this variable as the loop counter, so that the loop test looks like
+"while (cinfo.output_scanline < cinfo.output_height)".  (Note that the test
+should NOT be against image_height, unless you never use scaling.  The
+image_height field is the height of the original unscaled image.)
+The return value always equals the change in the value of output_scanline.
+
+If you don't use a suspending data source, it is safe to assume that
+jpeg_read_scanlines() reads at least one scanline per call, until the
+bottom of the image has been reached.
+
+If you use a buffer larger than one scanline, it is NOT safe to assume that
+jpeg_read_scanlines() fills it.  (The current implementation returns only a
+few scanlines per call, no matter how large a buffer you pass.)  So you must
+always provide a loop that calls jpeg_read_scanlines() repeatedly until the
+whole image has been read.
+
+
+7. jpeg_finish_decompress(...);
+
+After all the image data has been read, call jpeg_finish_decompress() to
+complete the decompression cycle.  This causes working memory associated
+with the JPEG object to be released.
+
+Typical code:
+
+	jpeg_finish_decompress(&cinfo);
+
+If using the stdio source manager, don't forget to close the source stdio
+stream if necessary.
+
+It is an error to call jpeg_finish_decompress() before reading the correct
+total number of scanlines.  If you wish to abort decompression, call
+jpeg_abort() as discussed below.
+
+After completing a decompression cycle, you may dispose of the JPEG object as
+discussed next, or you may use it to decompress another image.  In that case
+return to step 2 or 3 as appropriate.  If you do not change the source
+manager, the next image will be read from the same source.
+
+
+8. Release the JPEG decompression object.
+
+When you are done with a JPEG decompression object, destroy it by calling
+jpeg_destroy_decompress() or jpeg_destroy().  The previous discussion of
+destroying compression objects applies here too.
+
+Typical code:
+
+	jpeg_destroy_decompress(&cinfo);
+
+
+9. Aborting.
+
+You can abort a decompression cycle by calling jpeg_destroy_decompress() or
+jpeg_destroy() if you don't need the JPEG object any more, or
+jpeg_abort_decompress() or jpeg_abort() if you want to reuse the object.
+The previous discussion of aborting compression cycles applies here too.
+
+
+Mechanics of usage: include files, linking, etc
+-----------------------------------------------
+
+Applications using the JPEG library should include the header file jpeglib.h
+to obtain declarations of data types and routines.  Before including
+jpeglib.h, include system headers that define at least the typedefs FILE and
+size_t.  On ANSI-conforming systems, including <stdio.h> is sufficient; on
+older Unix systems, you may need <sys/types.h> to define size_t.
+
+If the application needs to refer to individual JPEG library error codes, also
+include jerror.h to define those symbols.
+
+jpeglib.h indirectly includes the files jconfig.h and jmorecfg.h.  If you are
+installing the JPEG header files in a system directory, you will want to
+install all four files: jpeglib.h, jerror.h, jconfig.h, jmorecfg.h.
+
+The most convenient way to include the JPEG code into your executable program
+is to prepare a library file ("libjpeg.a", or a corresponding name on non-Unix
+machines) and reference it at your link step.  If you use only half of the
+library (only compression or only decompression), only that much code will be
+included from the library, unless your linker is hopelessly brain-damaged.
+The supplied makefiles build libjpeg.a automatically (see install.doc).
+
+While you can build the JPEG library as a shared library if the whim strikes
+you, we don't really recommend it.  The trouble with shared libraries is that
+at some point you'll probably try to substitute a new version of the library
+without recompiling the calling applications.  That generally doesn't work
+because the parameter struct declarations usually change with each new
+version.  In other words, the library's API is *not* guaranteed binary
+compatible across versions; we only try to ensure source-code compatibility.
+(In hindsight, it might have been smarter to hide the parameter structs from
+applications and introduce a ton of access functions instead.  Too late now,
+however.)
+
+On some systems your application may need to set up a signal handler to ensure
+that temporary files are deleted if the program is interrupted.  This is most
+critical if you are on MS-DOS and use the jmemdos.c memory manager back end;
+it will try to grab extended memory for temp files, and that space will NOT be
+freed automatically.  See cjpeg.c or djpeg.c for an example signal handler.
+
+It may be worth pointing out that the core JPEG library does not actually
+require the stdio library: only the default source/destination managers and
+error handler need it.  You can use the library in a stdio-less environment
+if you replace those modules and use jmemnobs.c (or another memory manager of
+your own devising).  More info about the minimum system library requirements
+may be found in jinclude.h.
+
+
+ADVANCED FEATURES
+=================
+
+Compression parameter selection
+-------------------------------
+
+This section describes all the optional parameters you can set for JPEG
+compression, as well as the "helper" routines provided to assist in this
+task.  Proper setting of some parameters requires detailed understanding
+of the JPEG standard; if you don't know what a parameter is for, it's best
+not to mess with it!  See REFERENCES in the README file for pointers to
+more info about JPEG.
+
+It's a good idea to call jpeg_set_defaults() first, even if you plan to set
+all the parameters; that way your code is more likely to work with future JPEG
+libraries that have additional parameters.  For the same reason, we recommend
+you use a helper routine where one is provided, in preference to twiddling
+cinfo fields directly.
+
+The helper routines are:
+
+jpeg_set_defaults (j_compress_ptr cinfo)
+	This routine sets all JPEG parameters to reasonable defaults, using
+	only the input image's color space (field in_color_space, which must
+	already be set in cinfo).  Many applications will only need to use
+	this routine and perhaps jpeg_set_quality().
+
+jpeg_set_colorspace (j_compress_ptr cinfo, J_COLOR_SPACE colorspace)
+	Sets the JPEG file's colorspace (field jpeg_color_space) as specified,
+	and sets other color-space-dependent parameters appropriately.  See
+	"Special color spaces", below, before using this.  A large number of
+	parameters, including all per-component parameters, are set by this
+	routine; if you want to twiddle individual parameters you should call
+	jpeg_set_colorspace() before rather than after.
+
+jpeg_default_colorspace (j_compress_ptr cinfo)
+	Selects an appropriate JPEG colorspace based on cinfo->in_color_space,
+	and calls jpeg_set_colorspace().  This is actually a subroutine of
+	jpeg_set_defaults().  It's broken out in case you want to change
+	just the colorspace-dependent JPEG parameters.
+
+jpeg_set_quality (j_compress_ptr cinfo, int quality, boolean force_baseline)
+	Constructs JPEG quantization tables appropriate for the indicated
+	quality setting.  The quality value is expressed on the 0..100 scale
+	recommended by IJG (cjpeg's "-quality" switch uses this routine).
+	Note that the exact mapping from quality values to tables may change
+	in future IJG releases as more is learned about DCT quantization.
+	If the force_baseline parameter is TRUE, then the quantization table
+	entries are constrained to the range 1..255 for full JPEG baseline
+	compatibility.  In the current implementation, this only makes a
+	difference for quality settings below 25, and it effectively prevents
+	very small/low quality files from being generated.  The IJG decoder
+	is capable of reading the non-baseline files generated at low quality
+	settings when force_baseline is FALSE, but other decoders may not be.
+
+jpeg_set_linear_quality (j_compress_ptr cinfo, int scale_factor,
+			 boolean force_baseline)
+	Same as jpeg_set_quality() except that the generated tables are the
+	sample tables given in the JPEC spec section K.1, multiplied by the
+	specified scale factor (which is expressed as a percentage; thus
+	scale_factor = 100 reproduces the spec's tables).  Note that larger
+	scale factors give lower quality.  This entry point is useful for
+	conforming to the Adobe PostScript DCT conventions, but we do not
+	recommend linear scaling as a user-visible quality scale otherwise.
+	force_baseline again constrains the computed table entries to 1..255.
+
+int jpeg_quality_scaling (int quality)
+	Converts a value on the IJG-recommended quality scale to a linear
+	scaling percentage.  Note that this routine may change or go away
+	in future releases --- IJG may choose to adopt a scaling method that
+	can't be expressed as a simple scalar multiplier, in which case the
+	premise of this routine collapses.  Caveat user.
+
+jpeg_add_quant_table (j_compress_ptr cinfo, int which_tbl,
+		      const unsigned int *basic_table,
+		      int scale_factor, boolean force_baseline)
+	Allows an arbitrary quantization table to be created.  which_tbl
+	indicates which table slot to fill.  basic_table points to an array
+	of 64 unsigned ints given in normal array order.  These values are
+	multiplied by scale_factor/100 and then clamped to the range 1..65535
+	(or to 1..255 if force_baseline is TRUE).
+	CAUTION: prior to library version 6a, jpeg_add_quant_table expected
+	the basic table to be given in JPEG zigzag order.  If you need to
+	write code that works with either older or newer versions of this
+	routine, you must check the library version number.  Something like
+	"#if JPEG_LIB_VERSION >= 61" is the right test.
+
+jpeg_simple_progression (j_compress_ptr cinfo)
+	Generates a default scan script for writing a progressive-JPEG file.
+	This is the recommended method of creating a progressive file,
+	unless you want to make a custom scan sequence.  You must ensure that
+	the JPEG color space is set correctly before calling this routine.
+
+
+Compression parameters (cinfo fields) include:
+
+J_DCT_METHOD dct_method
+	Selects the algorithm used for the DCT step.  Choices are:
+		JDCT_ISLOW: slow but accurate integer algorithm
+		JDCT_IFAST: faster, less accurate integer method
+		JDCT_FLOAT: floating-point method
+		JDCT_DEFAULT: default method (normally JDCT_ISLOW)
+		JDCT_FASTEST: fastest method (normally JDCT_IFAST)
+	The FLOAT method is very slightly more accurate than the ISLOW method,
+	but may give different results on different machines due to varying
+	roundoff behavior.  The integer methods should give the same results
+	on all machines.  On machines with sufficiently fast FP hardware, the
+	floating-point method may also be the fastest.  The IFAST method is
+	considerably less accurate than the other two; its use is not
+	recommended if high quality is a concern.  JDCT_DEFAULT and
+	JDCT_FASTEST are macros configurable by each installation.
+
+J_COLOR_SPACE jpeg_color_space
+int num_components
+	The JPEG color space and corresponding number of components; see
+	"Special color spaces", below, for more info.  We recommend using
+	jpeg_set_color_space() if you want to change these.
+
+boolean optimize_coding
+	TRUE causes the compressor to compute optimal Huffman coding tables
+	for the image.  This requires an extra pass over the data and
+	therefore costs a good deal of space and time.  The default is
+	FALSE, which tells the compressor to use the supplied or default
+	Huffman tables.  In most cases optimal tables save only a few percent
+	of file size compared to the default tables.  Note that when this is
+	TRUE, you need not supply Huffman tables at all, and any you do
+	supply will be overwritten.
+
+unsigned int restart_interval
+int restart_in_rows
+	To emit restart markers in the JPEG file, set one of these nonzero.
+	Set restart_interval to specify the exact interval in MCU blocks.
+	Set restart_in_rows to specify the interval in MCU rows.  (If
+	restart_in_rows is not 0, then restart_interval is set after the
+	image width in MCUs is computed.)  Defaults are zero (no restarts).
+	One restart marker per MCU row is often a good choice.
+	NOTE: the overhead of restart markers is higher in grayscale JPEG
+	files than in color files, and MUCH higher in progressive JPEGs.
+	If you use restarts, you may want to use larger intervals in those
+	cases.
+
+const jpeg_scan_info * scan_info
+int num_scans
+	By default, scan_info is NULL; this causes the compressor to write a
+	single-scan sequential JPEG file.  If not NULL, scan_info points to
+	an array of scan definition records of length num_scans.  The
+	compressor will then write a JPEG file having one scan for each scan
+	definition record.  This is used to generate noninterleaved or
+	progressive JPEG files.  The library checks that the scan array
+	defines a valid JPEG scan sequence.  (jpeg_simple_progression creates
+	a suitable scan definition array for progressive JPEG.)  This is
+	discussed further under "Progressive JPEG support".
+
+int smoothing_factor
+	If non-zero, the input image is smoothed; the value should be 1 for
+	minimal smoothing to 100 for maximum smoothing.  Consult jcsample.c
+	for details of the smoothing algorithm.  The default is zero.
+
+boolean write_JFIF_header
+	If TRUE, a JFIF APP0 marker is emitted.  jpeg_set_defaults() and
+	jpeg_set_colorspace() set this TRUE if a JFIF-legal JPEG color space
+	(ie, YCbCr or grayscale) is selected, otherwise FALSE.
+
+UINT8 JFIF_major_version
+UINT8 JFIF_minor_version
+	The version number to be written into the JFIF marker.
+	jpeg_set_defaults() initializes the version to 1.01 (major=minor=1).
+	You should set it to 1.02 (major=1, minor=2) if you plan to write
+	any JFIF 1.02 extension markers.
+
+UINT8 density_unit
+UINT16 X_density
+UINT16 Y_density
+	The resolution information to be written into the JFIF marker;
+	not used otherwise.  density_unit may be 0 for unknown,
+	1 for dots/inch, or 2 for dots/cm.  The default values are 0,1,1
+	indicating square pixels of unknown size.
+
+boolean write_Adobe_marker
+	If TRUE, an Adobe APP14 marker is emitted.  jpeg_set_defaults() and
+	jpeg_set_colorspace() set this TRUE if JPEG color space RGB, CMYK,
+	or YCCK is selected, otherwise FALSE.  It is generally a bad idea
+	to set both write_JFIF_header and write_Adobe_marker.  In fact,
+	you probably shouldn't change the default settings at all --- the
+	default behavior ensures that the JPEG file's color space can be
+	recognized by the decoder.
+
+JQUANT_TBL * quant_tbl_ptrs[NUM_QUANT_TBLS]
+	Pointers to coefficient quantization tables, one per table slot,
+	or NULL if no table is defined for a slot.  Usually these should
+	be set via one of the above helper routines; jpeg_add_quant_table()
+	is general enough to define any quantization table.  The other
+	routines will set up table slot 0 for luminance quality and table
+	slot 1 for chrominance.
+
+JHUFF_TBL * dc_huff_tbl_ptrs[NUM_HUFF_TBLS]
+JHUFF_TBL * ac_huff_tbl_ptrs[NUM_HUFF_TBLS]
+	Pointers to Huffman coding tables, one per table slot, or NULL if
+	no table is defined for a slot.  Slots 0 and 1 are filled with the
+	JPEG sample tables by jpeg_set_defaults().  If you need to allocate
+	more table structures, jpeg_alloc_huff_table() may be used.
+	Note that optimal Huffman tables can be computed for an image
+	by setting optimize_coding, as discussed above; there's seldom
+	any need to mess with providing your own Huffman tables.
+
+There are some additional cinfo fields which are not documented here
+because you currently can't change them; for example, you can't set
+arith_code TRUE because arithmetic coding is unsupported.
+
+
+Per-component parameters are stored in the struct cinfo.comp_info[i] for
+component number i.  Note that components here refer to components of the
+JPEG color space, *not* the source image color space.  A suitably large
+comp_info[] array is allocated by jpeg_set_defaults(); if you choose not
+to use that routine, it's up to you to allocate the array.
+
+int component_id
+	The one-byte identifier code to be recorded in the JPEG file for
+	this component.  For the standard color spaces, we recommend you
+	leave the default values alone.
+
+int h_samp_factor
+int v_samp_factor
+	Horizontal and vertical sampling factors for the component; must
+	be 1..4 according to the JPEG standard.  Note that larger sampling
+	factors indicate a higher-resolution component; many people find
+	this behavior quite unintuitive.  The default values are 2,2 for
+	luminance components and 1,1 for chrominance components, except
+	for grayscale where 1,1 is used.
+
+int quant_tbl_no
+	Quantization table number for component.  The default value is
+	0 for luminance components and 1 for chrominance components.
+
+int dc_tbl_no
+int ac_tbl_no
+	DC and AC entropy coding table numbers.  The default values are
+	0 for luminance components and 1 for chrominance components.
+
+int component_index
+	Must equal the component's index in comp_info[].  (Beginning in
+	release v6, the compressor library will fill this in automatically;
+	you don't have to.)
+
+
+Decompression parameter selection
+---------------------------------
+
+Decompression parameter selection is somewhat simpler than compression
+parameter selection, since all of the JPEG internal parameters are
+recorded in the source file and need not be supplied by the application.
+(Unless you are working with abbreviated files, in which case see
+"Abbreviated datastreams", below.)  Decompression parameters control
+the postprocessing done on the image to deliver it in a format suitable
+for the application's use.  Many of the parameters control speed/quality
+tradeoffs, in which faster decompression may be obtained at the price of
+a poorer-quality image.  The defaults select the highest quality (slowest)
+processing.
+
+The following fields in the JPEG object are set by jpeg_read_header() and
+may be useful to the application in choosing decompression parameters:
+
+JDIMENSION image_width			Width and height of image
+JDIMENSION image_height
+int num_components			Number of color components
+J_COLOR_SPACE jpeg_color_space		Colorspace of image
+boolean saw_JFIF_marker			TRUE if a JFIF APP0 marker was seen
+  UINT8 JFIF_major_version		Version information from JFIF marker
+  UINT8 JFIF_minor_version
+  UINT8 density_unit			Resolution data from JFIF marker
+  UINT16 X_density
+  UINT16 Y_density
+boolean saw_Adobe_marker		TRUE if an Adobe APP14 marker was seen
+  UINT8 Adobe_transform			Color transform code from Adobe marker
+
+The JPEG color space, unfortunately, is something of a guess since the JPEG
+standard proper does not provide a way to record it.  In practice most files
+adhere to the JFIF or Adobe conventions, and the decoder will recognize these
+correctly.  See "Special color spaces", below, for more info.
+
+
+The decompression parameters that determine the basic properties of the
+returned image are:
+
+J_COLOR_SPACE out_color_space
+	Output color space.  jpeg_read_header() sets an appropriate default
+	based on jpeg_color_space; typically it will be RGB or grayscale.
+	The application can change this field to request output in a different
+	colorspace.  For example, set it to JCS_GRAYSCALE to get grayscale
+	output from a color file.  (This is useful for previewing: grayscale
+	output is faster than full color since the color components need not
+	be processed.)  Note that not all possible color space transforms are
+	currently implemented; you may need to extend jdcolor.c if you want an
+	unusual conversion.
+
+unsigned int scale_num, scale_denom
+	Scale the image by the fraction scale_num/scale_denom.  Default is
+	1/1, or no scaling.  Currently, the only supported scaling ratios
+	are 1/1, 1/2, 1/4, and 1/8.  (The library design allows for arbitrary
+	scaling ratios but this is not likely to be implemented any time soon.)
+	Smaller scaling ratios permit significantly faster decoding since
+	fewer pixels need be processed and a simpler IDCT method can be used.
+
+boolean quantize_colors
+	If set TRUE, colormapped output will be delivered.  Default is FALSE,
+	meaning that full-color output will be delivered.
+
+The next three parameters are relevant only if quantize_colors is TRUE.
+
+int desired_number_of_colors
+	Maximum number of colors to use in generating a library-supplied color
+	map (the actual number of colors is returned in a different field).
+	Default 256.  Ignored when the application supplies its own color map.
+
+boolean two_pass_quantize
+	If TRUE, an extra pass over the image is made to select a custom color
+	map for the image.  This usually looks a lot better than the one-size-
+	fits-all colormap that is used otherwise.  Default is TRUE.  Ignored
+	when the application supplies its own color map.
+
+J_DITHER_MODE dither_mode
+	Selects color dithering method.  Supported values are:
+		JDITHER_NONE	no dithering: fast, very low quality
+		JDITHER_ORDERED	ordered dither: moderate speed and quality
+		JDITHER_FS	Floyd-Steinberg dither: slow, high quality
+	Default is JDITHER_FS.  (At present, ordered dither is implemented
+	only in the single-pass, standard-colormap case.  If you ask for
+	ordered dither when two_pass_quantize is TRUE or when you supply
+	an external color map, you'll get F-S dithering.)
+
+When quantize_colors is TRUE, the target color map is described by the next
+two fields.  colormap is set to NULL by jpeg_read_header().  The application
+can supply a color map by setting colormap non-NULL and setting
+actual_number_of_colors to the map size.  Otherwise, jpeg_start_decompress()
+selects a suitable color map and sets these two fields itself.
+[Implementation restriction: at present, an externally supplied colormap is
+only accepted for 3-component output color spaces.]
+
+JSAMPARRAY colormap
+	The color map, represented as a 2-D pixel array of out_color_components
+	rows and actual_number_of_colors columns.  Ignored if not quantizing.
+	CAUTION: if the JPEG library creates its own colormap, the storage
+	pointed to by this field is released by jpeg_finish_decompress().
+	Copy the colormap somewhere else first, if you want to save it.
+
+int actual_number_of_colors
+	The number of colors in the color map.
+
+Additional decompression parameters that the application may set include:
+
+J_DCT_METHOD dct_method
+	Selects the algorithm used for the DCT step.  Choices are the same
+	as described above for compression.
+
+boolean do_fancy_upsampling
+	If TRUE, do careful upsampling of chroma components.  If FALSE,
+	a faster but sloppier method is used.  Default is TRUE.  The visual
+	impact of the sloppier method is often very small.
+
+boolean do_block_smoothing
+	If TRUE, interblock smoothing is applied in early stages of decoding
+	progressive JPEG files; if FALSE, not.  Default is TRUE.  Early
+	progression stages look "fuzzy" with smoothing, "blocky" without.
+	In any case, block smoothing ceases to be applied after the first few
+	AC coefficients are known to full accuracy, so it is relevant only
+	when using buffered-image mode for progressive images.
+
+boolean enable_1pass_quant
+boolean enable_external_quant
+boolean enable_2pass_quant
+	These are significant only in buffered-image mode, which is
+	described in its own section below.
+
+
+The output image dimensions are given by the following fields.  These are
+computed from the source image dimensions and the decompression parameters
+by jpeg_start_decompress().  You can also call jpeg_calc_output_dimensions()
+to obtain the values that will result from the current parameter settings.
+This can be useful if you are trying to pick a scaling ratio that will get
+close to a desired target size.  It's also important if you are using the
+JPEG library's memory manager to allocate output buffer space, because you
+are supposed to request such buffers *before* jpeg_start_decompress().
+
+JDIMENSION output_width		Actual dimensions of output image.
+JDIMENSION output_height
+int out_color_components	Number of color components in out_color_space.
+int output_components		Number of color components returned.
+int rec_outbuf_height		Recommended height of scanline buffer.
+
+When quantizing colors, output_components is 1, indicating a single color map
+index per pixel.  Otherwise it equals out_color_components.  The output arrays
+are required to be output_width * output_components JSAMPLEs wide.
+
+rec_outbuf_height is the recommended minimum height (in scanlines) of the
+buffer passed to jpeg_read_scanlines().  If the buffer is smaller, the
+library will still work, but time will be wasted due to unnecessary data
+copying.  In high-quality modes, rec_outbuf_height is always 1, but some
+faster, lower-quality modes set it to larger values (typically 2 to 4).
+If you are going to ask for a high-speed processing mode, you may as well
+go to the trouble of honoring rec_outbuf_height so as to avoid data copying.
+(An output buffer larger than rec_outbuf_height lines is OK, but won't
+provide any material speed improvement over that height.)
+
+
+Special color spaces
+--------------------
+
+The JPEG standard itself is "color blind" and doesn't specify any particular
+color space.  It is customary to convert color data to a luminance/chrominance
+color space before compressing, since this permits greater compression.  The
+existing de-facto JPEG file format standards specify YCbCr or grayscale data
+(JFIF), or grayscale, RGB, YCbCr, CMYK, or YCCK (Adobe).  For special
+applications such as multispectral images, other color spaces can be used,
+but it must be understood that such files will be unportable.
+
+The JPEG library can handle the most common colorspace conversions (namely
+RGB <=> YCbCr and CMYK <=> YCCK).  It can also deal with data of an unknown
+color space, passing it through without conversion.  If you deal extensively
+with an unusual color space, you can easily extend the library to understand
+additional color spaces and perform appropriate conversions.
+
+For compression, the source data's color space is specified by field
+in_color_space.  This is transformed to the JPEG file's color space given
+by jpeg_color_space.  jpeg_set_defaults() chooses a reasonable JPEG color
+space depending on in_color_space, but you can override this by calling
+jpeg_set_colorspace().  Of course you must select a supported transformation.
+jccolor.c currently supports the following transformations:
+	RGB => YCbCr
+	RGB => GRAYSCALE
+	YCbCr => GRAYSCALE
+	CMYK => YCCK
+plus the null transforms: GRAYSCALE => GRAYSCALE, RGB => RGB,
+YCbCr => YCbCr, CMYK => CMYK, YCCK => YCCK, and UNKNOWN => UNKNOWN.
+
+The de-facto file format standards (JFIF and Adobe) specify APPn markers that
+indicate the color space of the JPEG file.  It is important to ensure that
+these are written correctly, or omitted if the JPEG file's color space is not
+one of the ones supported by the de-facto standards.  jpeg_set_colorspace()
+will set the compression parameters to include or omit the APPn markers
+properly, so long as it is told the truth about the JPEG color space.
+For example, if you are writing some random 3-component color space without
+conversion, don't try to fake out the library by setting in_color_space and
+jpeg_color_space to JCS_YCbCr; use JCS_UNKNOWN.  You may want to write an
+APPn marker of your own devising to identify the colorspace --- see "Special
+markers", below.
+
+When told that the color space is UNKNOWN, the library will default to using
+luminance-quality compression parameters for all color components.  You may
+well want to change these parameters.  See the source code for
+jpeg_set_colorspace(), in jcparam.c, for details.
+
+For decompression, the JPEG file's color space is given in jpeg_color_space,
+and this is transformed to the output color space out_color_space.
+jpeg_read_header's setting of jpeg_color_space can be relied on if the file
+conforms to JFIF or Adobe conventions, but otherwise it is no better than a
+guess.  If you know the JPEG file's color space for certain, you can override
+jpeg_read_header's guess by setting jpeg_color_space.  jpeg_read_header also
+selects a default output color space based on (its guess of) jpeg_color_space;
+set out_color_space to override this.  Again, you must select a supported
+transformation.  jdcolor.c currently supports
+	YCbCr => GRAYSCALE
+	YCbCr => RGB
+	GRAYSCALE => RGB
+	YCCK => CMYK
+as well as the null transforms.  (Since GRAYSCALE=>RGB is provided, an
+application can force grayscale JPEGs to look like color JPEGs if it only
+wants to handle one case.)
+
+The two-pass color quantizer, jquant2.c, is specialized to handle RGB data
+(it weights distances appropriately for RGB colors).  You'll need to modify
+the code if you want to use it for non-RGB output color spaces.  Note that
+jquant2.c is used to map to an application-supplied colormap as well as for
+the normal two-pass colormap selection process.
+
+CAUTION: it appears that Adobe Photoshop writes inverted data in CMYK JPEG
+files: 0 represents 100% ink coverage, rather than 0% ink as you'd expect.
+This is arguably a bug in Photoshop, but if you need to work with Photoshop
+CMYK files, you will have to deal with it in your application.  We cannot
+"fix" this in the library by inverting the data during the CMYK<=>YCCK
+transform, because that would break other applications, notably Ghostscript.
+Photoshop versions prior to 3.0 write EPS files containing JPEG-encoded CMYK
+data in the same inverted-YCCK representation used in bare JPEG files, but
+the surrounding PostScript code performs an inversion using the PS image
+operator.  I am told that Photoshop 3.0 will write uninverted YCCK in
+EPS/JPEG files, and will omit the PS-level inversion.  (But the data
+polarity used in bare JPEG files will not change in 3.0.)  In either case,
+the JPEG library must not invert the data itself, or else Ghostscript would
+read these EPS files incorrectly.
+
+
+Error handling
+--------------
+
+When the default error handler is used, any error detected inside the JPEG
+routines will cause a message to be printed on stderr, followed by exit().
+You can supply your own error handling routines to override this behavior
+and to control the treatment of nonfatal warnings and trace/debug messages.
+The file example.c illustrates the most common case, which is to have the
+application regain control after an error rather than exiting.
+
+The JPEG library never writes any message directly; it always goes through
+the error handling routines.  Three classes of messages are recognized:
+  * Fatal errors: the library cannot continue.
+  * Warnings: the library can continue, but the data is corrupt, and a
+    damaged output image is likely to result.
+  * Trace/informational messages.  These come with a trace level indicating
+    the importance of the message; you can control the verbosity of the
+    program by adjusting the maximum trace level that will be displayed.
+
+You may, if you wish, simply replace the entire JPEG error handling module
+(jerror.c) with your own code.  However, you can avoid code duplication by
+only replacing some of the routines depending on the behavior you need.
+This is accomplished by calling jpeg_std_error() as usual, but then overriding
+some of the method pointers in the jpeg_error_mgr struct, as illustrated by
+example.c.
+
+All of the error handling routines will receive a pointer to the JPEG object
+(a j_common_ptr which points to either a jpeg_compress_struct or a
+jpeg_decompress_struct; if you need to tell which, test the is_decompressor
+field).  This struct includes a pointer to the error manager struct in its
+"err" field.  Frequently, custom error handler routines will need to access
+additional data which is not known to the JPEG library or the standard error
+handler.  The most convenient way to do this is to embed either the JPEG
+object or the jpeg_error_mgr struct in a larger structure that contains
+additional fields; then casting the passed pointer provides access to the
+additional fields.  Again, see example.c for one way to do it.  (Beginning
+with IJG version 6b, there is also a void pointer "client_data" in each
+JPEG object, which the application can also use to find related data.
+The library does not touch client_data at all.)
+
+The individual methods that you might wish to override are:
+
+error_exit (j_common_ptr cinfo)
+	Receives control for a fatal error.  Information sufficient to
+	generate the error message has been stored in cinfo->err; call
+	output_message to display it.  Control must NOT return to the caller;
+	generally this routine will exit() or longjmp() somewhere.
+	Typically you would override this routine to get rid of the exit()
+	default behavior.  Note that if you continue processing, you should
+	clean up the JPEG object with jpeg_abort() or jpeg_destroy().
+
+output_message (j_common_ptr cinfo)
+	Actual output of any JPEG message.  Override this to send messages
+	somewhere other than stderr.  Note that this method does not know
+	how to generate a message, only where to send it.
+
+format_message (j_common_ptr cinfo, char * buffer)
+	Constructs a readable error message string based on the error info
+	stored in cinfo->err.  This method is called by output_message.  Few
+	applications should need to override this method.  One possible
+	reason for doing so is to implement dynamic switching of error message
+	language.
+
+emit_message (j_common_ptr cinfo, int msg_level)
+	Decide whether or not to emit a warning or trace message; if so,
+	calls output_message.  The main reason for overriding this method
+	would be to abort on warnings.  msg_level is -1 for warnings,
+	0 and up for trace messages.
+
+Only error_exit() and emit_message() are called from the rest of the JPEG
+library; the other two are internal to the error handler.
+
+The actual message texts are stored in an array of strings which is pointed to
+by the field err->jpeg_message_table.  The messages are numbered from 0 to
+err->last_jpeg_message, and it is these code numbers that are used in the
+JPEG library code.  You could replace the message texts (for instance, with
+messages in French or German) by changing the message table pointer.  See
+jerror.h for the default texts.  CAUTION: this table will almost certainly
+change or grow from one library version to the next.
+
+It may be useful for an application to add its own message texts that are
+handled by the same mechanism.  The error handler supports a second "add-on"
+message table for this purpose.  To define an addon table, set the pointer
+err->addon_message_table and the message numbers err->first_addon_message and
+err->last_addon_message.  If you number the addon messages beginning at 1000
+or so, you won't have to worry about conflicts with the library's built-in
+messages.  See the sample applications cjpeg/djpeg for an example of using
+addon messages (the addon messages are defined in cderror.h).
+
+Actual invocation of the error handler is done via macros defined in jerror.h:
+	ERREXITn(...)	for fatal errors
+	WARNMSn(...)	for corrupt-data warnings
+	TRACEMSn(...)	for trace and informational messages.
+These macros store the message code and any additional parameters into the
+error handler struct, then invoke the error_exit() or emit_message() method.
+The variants of each macro are for varying numbers of additional parameters.
+The additional parameters are inserted into the generated message using
+standard printf() format codes.
+
+See jerror.h and jerror.c for further details.
+
+
+Compressed data handling (source and destination managers)
+----------------------------------------------------------
+
+The JPEG compression library sends its compressed data to a "destination
+manager" module.  The default destination manager just writes the data to a
+stdio stream, but you can provide your own manager to do something else.
+Similarly, the decompression library calls a "source manager" to obtain the
+compressed data; you can provide your own source manager if you want the data
+to come from somewhere other than a stdio stream.
+
+In both cases, compressed data is processed a bufferload at a time: the
+destination or source manager provides a work buffer, and the library invokes
+the manager only when the buffer is filled or emptied.  (You could define a
+one-character buffer to force the manager to be invoked for each byte, but
+that would be rather inefficient.)  The buffer's size and location are
+controlled by the manager, not by the library.  For example, if you desired to
+decompress a JPEG datastream that was all in memory, you could just make the
+buffer pointer and length point to the original data in memory.  Then the
+buffer-reload procedure would be invoked only if the decompressor ran off the
+end of the datastream, which would indicate an erroneous datastream.
+
+The work buffer is defined as an array of datatype JOCTET, which is generally
+"char" or "unsigned char".  On a machine where char is not exactly 8 bits
+wide, you must define JOCTET as a wider data type and then modify the data
+source and destination modules to transcribe the work arrays into 8-bit units
+on external storage.
+
+A data destination manager struct contains a pointer and count defining the
+next byte to write in the work buffer and the remaining free space:
+
+	JOCTET * next_output_byte;  /* => next byte to write in buffer */
+	size_t free_in_buffer;      /* # of byte spaces remaining in buffer */
+
+The library increments the pointer and decrements the count until the buffer
+is filled.  The manager's empty_output_buffer method must reset the pointer
+and count.  The manager is expected to remember the buffer's starting address
+and total size in private fields not visible to the library.
+
+A data destination manager provides three methods:
+
+init_destination (j_compress_ptr cinfo)
+	Initialize destination.  This is called by jpeg_start_compress()
+	before any data is actually written.  It must initialize
+	next_output_byte and free_in_buffer.  free_in_buffer must be
+	initialized to a positive value.
+
+empty_output_buffer (j_compress_ptr cinfo)
+	This is called whenever the buffer has filled (free_in_buffer
+	reaches zero).  In typical applications, it should write out the
+	*entire* buffer (use the saved start address and buffer length;
+	ignore the current state of next_output_byte and free_in_buffer).
+	Then reset the pointer & count to the start of the buffer, and
+	return TRUE indicating that the buffer has been dumped.
+	free_in_buffer must be set to a positive value when TRUE is
+	returned.  A FALSE return should only be used when I/O suspension is
+	desired (this operating mode is discussed in the next section).
+
+term_destination (j_compress_ptr cinfo)
+	Terminate destination --- called by jpeg_finish_compress() after all
+	data has been written.  In most applications, this must flush any
+	data remaining in the buffer.  Use either next_output_byte or
+	free_in_buffer to determine how much data is in the buffer.
+
+term_destination() is NOT called by jpeg_abort() or jpeg_destroy().  If you
+want the destination manager to be cleaned up during an abort, you must do it
+yourself.
+
+You will also need code to create a jpeg_destination_mgr struct, fill in its
+method pointers, and insert a pointer to the struct into the "dest" field of
+the JPEG compression object.  This can be done in-line in your setup code if
+you like, but it's probably cleaner to provide a separate routine similar to
+the jpeg_stdio_dest() routine of the supplied destination manager.
+
+Decompression source managers follow a parallel design, but with some
+additional frammishes.  The source manager struct contains a pointer and count
+defining the next byte to read from the work buffer and the number of bytes
+remaining:
+
+	const JOCTET * next_input_byte; /* => next byte to read from buffer */
+	size_t bytes_in_buffer;         /* # of bytes remaining in buffer */
+
+The library increments the pointer and decrements the count until the buffer
+is emptied.  The manager's fill_input_buffer method must reset the pointer and
+count.  In most applications, the manager must remember the buffer's starting
+address and total size in private fields not visible to the library.
+
+A data source manager provides five methods:
+
+init_source (j_decompress_ptr cinfo)
+	Initialize source.  This is called by jpeg_read_header() before any
+	data is actually read.  Unlike init_destination(), it may leave
+	bytes_in_buffer set to 0 (in which case a fill_input_buffer() call
+	will occur immediately).
+
+fill_input_buffer (j_decompress_ptr cinfo)
+	This is called whenever bytes_in_buffer has reached zero and more
+	data is wanted.  In typical applications, it should read fresh data
+	into the buffer (ignoring the current state of next_input_byte and
+	bytes_in_buffer), reset the pointer & count to the start of the
+	buffer, and return TRUE indicating that the buffer has been reloaded.
+	It is not necessary to fill the buffer entirely, only to obtain at
+	least one more byte.  bytes_in_buffer MUST be set to a positive value
+	if TRUE is returned.  A FALSE return should only be used when I/O
+	suspension is desired (this mode is discussed in the next section).
+
+skip_input_data (j_decompress_ptr cinfo, long num_bytes)
+	Skip num_bytes worth of data.  The buffer pointer and count should
+	be advanced over num_bytes input bytes, refilling the buffer as
+	needed.  This is used to skip over a potentially large amount of
+	uninteresting data (such as an APPn marker).  In some applications
+	it may be possible to optimize away the reading of the skipped data,
+	but it's not clear that being smart is worth much trouble; large
+	skips are uncommon.  bytes_in_buffer may be zero on return.
+	A zero or negative skip count should be treated as a no-op.
+
+resync_to_restart (j_decompress_ptr cinfo, int desired)
+	This routine is called only when the decompressor has failed to find
+	a restart (RSTn) marker where one is expected.  Its mission is to
+	find a suitable point for resuming decompression.  For most
+	applications, we recommend that you just use the default resync
+	procedure, jpeg_resync_to_restart().  However, if you are able to back
+	up in the input data stream, or if you have a-priori knowledge about
+	the likely location of restart markers, you may be able to do better.
+	Read the read_restart_marker() and jpeg_resync_to_restart() routines
+	in jdmarker.c if you think you'd like to implement your own resync
+	procedure.
+
+term_source (j_decompress_ptr cinfo)
+	Terminate source --- called by jpeg_finish_decompress() after all
+	data has been read.  Often a no-op.
+
+For both fill_input_buffer() and skip_input_data(), there is no such thing
+as an EOF return.  If the end of the file has been reached, the routine has
+a choice of exiting via ERREXIT() or inserting fake data into the buffer.
+In most cases, generating a warning message and inserting a fake EOI marker
+is the best course of action --- this will allow the decompressor to output
+however much of the image is there.  In pathological cases, the decompressor
+may swallow the EOI and again demand data ... just keep feeding it fake EOIs.
+jdatasrc.c illustrates the recommended error recovery behavior.
+
+term_source() is NOT called by jpeg_abort() or jpeg_destroy().  If you want
+the source manager to be cleaned up during an abort, you must do it yourself.
+
+You will also need code to create a jpeg_source_mgr struct, fill in its method
+pointers, and insert a pointer to the struct into the "src" field of the JPEG
+decompression object.  This can be done in-line in your setup code if you
+like, but it's probably cleaner to provide a separate routine similar to the
+jpeg_stdio_src() routine of the supplied source manager.
+
+For more information, consult the stdio source and destination managers
+in jdatasrc.c and jdatadst.c.
+
+
+I/O suspension
+--------------
+
+Some applications need to use the JPEG library as an incremental memory-to-
+memory filter: when the compressed data buffer is filled or emptied, they want
+control to return to the outer loop, rather than expecting that the buffer can
+be emptied or reloaded within the data source/destination manager subroutine.
+The library supports this need by providing an "I/O suspension" mode, which we
+describe in this section.
+
+The I/O suspension mode is not a panacea: nothing is guaranteed about the
+maximum amount of time spent in any one call to the library, so it will not
+eliminate response-time problems in single-threaded applications.  If you
+need guaranteed response time, we suggest you "bite the bullet" and implement
+a real multi-tasking capability.
+
+To use I/O suspension, cooperation is needed between the calling application
+and the data source or destination manager; you will always need a custom
+source/destination manager.  (Please read the previous section if you haven't
+already.)  The basic idea is that the empty_output_buffer() or
+fill_input_buffer() routine is a no-op, merely returning FALSE to indicate
+that it has done nothing.  Upon seeing this, the JPEG library suspends
+operation and returns to its caller.  The surrounding application is
+responsible for emptying or refilling the work buffer before calling the
+JPEG library again.
+
+Compression suspension:
+
+For compression suspension, use an empty_output_buffer() routine that returns
+FALSE; typically it will not do anything else.  This will cause the
+compressor to return to the caller of jpeg_write_scanlines(), with the return
+value indicating that not all the supplied scanlines have been accepted.
+The application must make more room in the output buffer, adjust the output
+buffer pointer/count appropriately, and then call jpeg_write_scanlines()
+again, pointing to the first unconsumed scanline.
+
+When forced to suspend, the compressor will backtrack to a convenient stopping
+point (usually the start of the current MCU); it will regenerate some output
+data when restarted.  Therefore, although empty_output_buffer() is only
+called when the buffer is filled, you should NOT write out the entire buffer
+after a suspension.  Write only the data up to the current position of
+next_output_byte/free_in_buffer.  The data beyond that point will be
+regenerated after resumption.
+
+Because of the backtracking behavior, a good-size output buffer is essential
+for efficiency; you don't want the compressor to suspend often.  (In fact, an
+overly small buffer could lead to infinite looping, if a single MCU required
+more data than would fit in the buffer.)  We recommend a buffer of at least
+several Kbytes.  You may want to insert explicit code to ensure that you don't
+call jpeg_write_scanlines() unless there is a reasonable amount of space in
+the output buffer; in other words, flush the buffer before trying to compress
+more data.
+
+The compressor does not allow suspension while it is trying to write JPEG
+markers at the beginning and end of the file.  This means that:
+  * At the beginning of a compression operation, there must be enough free
+    space in the output buffer to hold the header markers (typically 600 or
+    so bytes).  The recommended buffer size is bigger than this anyway, so
+    this is not a problem as long as you start with an empty buffer.  However,
+    this restriction might catch you if you insert large special markers, such
+    as a JFIF thumbnail image, without flushing the buffer afterwards.
+  * When you call jpeg_finish_compress(), there must be enough space in the
+    output buffer to emit any buffered data and the final EOI marker.  In the
+    current implementation, half a dozen bytes should suffice for this, but
+    for safety's sake we recommend ensuring that at least 100 bytes are free
+    before calling jpeg_finish_compress().
+
+A more significant restriction is that jpeg_finish_compress() cannot suspend.
+This means you cannot use suspension with multi-pass operating modes, namely
+Huffman code optimization and multiple-scan output.  Those modes write the
+whole file during jpeg_finish_compress(), which will certainly result in
+buffer overrun.  (Note that this restriction applies only to compression,
+not decompression.  The decompressor supports input suspension in all of its
+operating modes.)
+
+Decompression suspension:
+
+For decompression suspension, use a fill_input_buffer() routine that simply
+returns FALSE (except perhaps during error recovery, as discussed below).
+This will cause the decompressor to return to its caller with an indication
+that suspension has occurred.  This can happen at four places:
+  * jpeg_read_header(): will return JPEG_SUSPENDED.
+  * jpeg_start_decompress(): will return FALSE, rather than its usual TRUE.
+  * jpeg_read_scanlines(): will return the number of scanlines already
+	completed (possibly 0).
+  * jpeg_finish_decompress(): will return FALSE, rather than its usual TRUE.
+The surrounding application must recognize these cases, load more data into
+the input buffer, and repeat the call.  In the case of jpeg_read_scanlines(),
+increment the passed pointers past any scanlines successfully read.
+
+Just as with compression, the decompressor will typically backtrack to a
+convenient restart point before suspending.  When fill_input_buffer() is
+called, next_input_byte/bytes_in_buffer point to the current restart point,
+which is where the decompressor will backtrack to if FALSE is returned.
+The data beyond that position must NOT be discarded if you suspend; it needs
+to be re-read upon resumption.  In most implementations, you'll need to shift
+this data down to the start of your work buffer and then load more data after
+it.  Again, this behavior means that a several-Kbyte work buffer is essential
+for decent performance; furthermore, you should load a reasonable amount of
+new data before resuming decompression.  (If you loaded, say, only one new
+byte each time around, you could waste a LOT of cycles.)
+
+The skip_input_data() source manager routine requires special care in a
+suspension scenario.  This routine is NOT granted the ability to suspend the
+decompressor; it can decrement bytes_in_buffer to zero, but no more.  If the
+requested skip distance exceeds the amount of data currently in the input
+buffer, then skip_input_data() must set bytes_in_buffer to zero and record the
+additional skip distance somewhere else.  The decompressor will immediately
+call fill_input_buffer(), which should return FALSE, which will cause a
+suspension return.  The surrounding application must then arrange to discard
+the recorded number of bytes before it resumes loading the input buffer.
+(Yes, this design is rather baroque, but it avoids complexity in the far more
+common case where a non-suspending source manager is used.)
+
+If the input data has been exhausted, we recommend that you emit a warning
+and insert dummy EOI markers just as a non-suspending data source manager
+would do.  This can be handled either in the surrounding application logic or
+within fill_input_buffer(); the latter is probably more efficient.  If
+fill_input_buffer() knows that no more data is available, it can set the
+pointer/count to point to a dummy EOI marker and then return TRUE just as
+though it had read more data in a non-suspending situation.
+
+The decompressor does not attempt to suspend within standard JPEG markers;
+instead it will backtrack to the start of the marker and reprocess the whole
+marker next time.  Hence the input buffer must be large enough to hold the
+longest standard marker in the file.  Standard JPEG markers should normally
+not exceed a few hundred bytes each (DHT tables are typically the longest).
+We recommend at least a 2K buffer for performance reasons, which is much
+larger than any correct marker is likely to be.  For robustness against
+damaged marker length counts, you may wish to insert a test in your
+application for the case that the input buffer is completely full and yet
+the decoder has suspended without consuming any data --- otherwise, if this
+situation did occur, it would lead to an endless loop.  (The library can't
+provide this test since it has no idea whether "the buffer is full", or
+even whether there is a fixed-size input buffer.)
+
+The input buffer would need to be 64K to allow for arbitrary COM or APPn
+markers, but these are handled specially: they are either saved into allocated
+memory, or skipped over by calling skip_input_data().  In the former case,
+suspension is handled correctly, and in the latter case, the problem of
+buffer overrun is placed on skip_input_data's shoulders, as explained above.
+Note that if you provide your own marker handling routine for large markers,
+you should consider how to deal with buffer overflow.
+
+Multiple-buffer management:
+
+In some applications it is desirable to store the compressed data in a linked
+list of buffer areas, so as to avoid data copying.  This can be handled by
+having empty_output_buffer() or fill_input_buffer() set the pointer and count
+to reference the next available buffer; FALSE is returned only if no more
+buffers are available.  Although seemingly straightforward, there is a
+pitfall in this approach: the backtrack that occurs when FALSE is returned
+could back up into an earlier buffer.  For example, when fill_input_buffer()
+is called, the current pointer & count indicate the backtrack restart point.
+Since fill_input_buffer() will set the pointer and count to refer to a new
+buffer, the restart position must be saved somewhere else.  Suppose a second
+call to fill_input_buffer() occurs in the same library call, and no
+additional input data is available, so fill_input_buffer must return FALSE.
+If the JPEG library has not moved the pointer/count forward in the current
+buffer, then *the correct restart point is the saved position in the prior
+buffer*.  Prior buffers may be discarded only after the library establishes
+a restart point within a later buffer.  Similar remarks apply for output into
+a chain of buffers.
+
+The library will never attempt to backtrack over a skip_input_data() call,
+so any skipped data can be permanently discarded.  You still have to deal
+with the case of skipping not-yet-received data, however.
+
+It's much simpler to use only a single buffer; when fill_input_buffer() is
+called, move any unconsumed data (beyond the current pointer/count) down to
+the beginning of this buffer and then load new data into the remaining buffer
+space.  This approach requires a little more data copying but is far easier
+to get right.
+
+
+Progressive JPEG support
+------------------------
+
+Progressive JPEG rearranges the stored data into a series of scans of
+increasing quality.  In situations where a JPEG file is transmitted across a
+slow communications link, a decoder can generate a low-quality image very
+quickly from the first scan, then gradually improve the displayed quality as
+more scans are received.  The final image after all scans are complete is
+identical to that of a regular (sequential) JPEG file of the same quality
+setting.  Progressive JPEG files are often slightly smaller than equivalent
+sequential JPEG files, but the possibility of incremental display is the main
+reason for using progressive JPEG.
+
+The IJG encoder library generates progressive JPEG files when given a
+suitable "scan script" defining how to divide the data into scans.
+Creation of progressive JPEG files is otherwise transparent to the encoder.
+Progressive JPEG files can also be read transparently by the decoder library.
+If the decoding application simply uses the library as defined above, it
+will receive a final decoded image without any indication that the file was
+progressive.  Of course, this approach does not allow incremental display.
+To perform incremental display, an application needs to use the decoder
+library's "buffered-image" mode, in which it receives a decoded image
+multiple times.
+
+Each displayed scan requires about as much work to decode as a full JPEG
+image of the same size, so the decoder must be fairly fast in relation to the
+data transmission rate in order to make incremental display useful.  However,
+it is possible to skip displaying the image and simply add the incoming bits
+to the decoder's coefficient buffer.  This is fast because only Huffman
+decoding need be done, not IDCT, upsampling, colorspace conversion, etc.
+The IJG decoder library allows the application to switch dynamically between
+displaying the image and simply absorbing the incoming bits.  A properly
+coded application can automatically adapt the number of display passes to
+suit the time available as the image is received.  Also, a final
+higher-quality display cycle can be performed from the buffered data after
+the end of the file is reached.
+
+Progressive compression:
+
+To create a progressive JPEG file (or a multiple-scan sequential JPEG file),
+set the scan_info cinfo field to point to an array of scan descriptors, and
+perform compression as usual.  Instead of constructing your own scan list,
+you can call the jpeg_simple_progression() helper routine to create a
+recommended progression sequence; this method should be used by all
+applications that don't want to get involved in the nitty-gritty of
+progressive scan sequence design.  (If you want to provide user control of
+scan sequences, you may wish to borrow the scan script reading code found
+in rdswitch.c, so that you can read scan script files just like cjpeg's.)
+When scan_info is not NULL, the compression library will store DCT'd data
+into a buffer array as jpeg_write_scanlines() is called, and will emit all
+the requested scans during jpeg_finish_compress().  This implies that
+multiple-scan output cannot be created with a suspending data destination
+manager, since jpeg_finish_compress() does not support suspension.  We
+should also note that the compressor currently forces Huffman optimization
+mode when creating a progressive JPEG file, because the default Huffman
+tables are unsuitable for progressive files.
+
+Progressive decompression:
+
+When buffered-image mode is not used, the decoder library will read all of
+a multi-scan file during jpeg_start_decompress(), so that it can provide a
+final decoded image.  (Here "multi-scan" means either progressive or
+multi-scan sequential.)  This makes multi-scan files transparent to the
+decoding application.  However, existing applications that used suspending
+input with version 5 of the IJG library will need to be modified to check
+for a suspension return from jpeg_start_decompress().
+
+To perform incremental display, an application must use the library's
+buffered-image mode.  This is described in the next section.
+
+
+Buffered-image mode
+-------------------
+
+In buffered-image mode, the library stores the partially decoded image in a
+coefficient buffer, from which it can be read out as many times as desired.
+This mode is typically used for incremental display of progressive JPEG files,
+but it can be used with any JPEG file.  Each scan of a progressive JPEG file
+adds more data (more detail) to the buffered image.  The application can
+display in lockstep with the source file (one display pass per input scan),
+or it can allow input processing to outrun display processing.  By making
+input and display processing run independently, it is possible for the
+application to adapt progressive display to a wide range of data transmission
+rates.
+
+The basic control flow for buffered-image decoding is
+
+	jpeg_create_decompress()
+	set data source
+	jpeg_read_header()
+	set overall decompression parameters
+	cinfo.buffered_image = TRUE;	/* select buffered-image mode */
+	jpeg_start_decompress()
+	for (each output pass) {
+	    adjust output decompression parameters if required
+	    jpeg_start_output()		/* start a new output pass */
+	    for (all scanlines in image) {
+	        jpeg_read_scanlines()
+	        display scanlines
+	    }
+	    jpeg_finish_output()	/* terminate output pass */
+	}
+	jpeg_finish_decompress()
+	jpeg_destroy_decompress()
+
+This differs from ordinary unbuffered decoding in that there is an additional
+level of looping.  The application can choose how many output passes to make
+and how to display each pass.
+
+The simplest approach to displaying progressive images is to do one display
+pass for each scan appearing in the input file.  In this case the outer loop
+condition is typically
+	while (! jpeg_input_complete(&cinfo))
+and the start-output call should read
+	jpeg_start_output(&cinfo, cinfo.input_scan_number);
+The second parameter to jpeg_start_output() indicates which scan of the input
+file is to be displayed; the scans are numbered starting at 1 for this
+purpose.  (You can use a loop counter starting at 1 if you like, but using
+the library's input scan counter is easier.)  The library automatically reads
+data as necessary to complete each requested scan, and jpeg_finish_output()
+advances to the next scan or end-of-image marker (hence input_scan_number
+will be incremented by the time control arrives back at jpeg_start_output()).
+With this technique, data is read from the input file only as needed, and
+input and output processing run in lockstep.
+
+After reading the final scan and reaching the end of the input file, the
+buffered image remains available; it can be read additional times by
+repeating the jpeg_start_output()/jpeg_read_scanlines()/jpeg_finish_output()
+sequence.  For example, a useful technique is to use fast one-pass color
+quantization for display passes made while the image is arriving, followed by
+a final display pass using two-pass quantization for highest quality.  This
+is done by changing the library parameters before the final output pass.
+Changing parameters between passes is discussed in detail below.
+
+In general the last scan of a progressive file cannot be recognized as such
+until after it is read, so a post-input display pass is the best approach if
+you want special processing in the final pass.
+
+When done with the image, be sure to call jpeg_finish_decompress() to release
+the buffered image (or just use jpeg_destroy_decompress()).
+
+If input data arrives faster than it can be displayed, the application can
+cause the library to decode input data in advance of what's needed to produce
+output.  This is done by calling the routine jpeg_consume_input().
+The return value is one of the following:
+	JPEG_REACHED_SOS:    reached an SOS marker (the start of a new scan)
+	JPEG_REACHED_EOI:    reached the EOI marker (end of image)
+	JPEG_ROW_COMPLETED:  completed reading one MCU row of compressed data
+	JPEG_SCAN_COMPLETED: completed reading last MCU row of current scan
+	JPEG_SUSPENDED:      suspended before completing any of the above
+(JPEG_SUSPENDED can occur only if a suspending data source is used.)  This
+routine can be called at any time after initializing the JPEG object.  It
+reads some additional data and returns when one of the indicated significant
+events occurs.  (If called after the EOI marker is reached, it will
+immediately return JPEG_REACHED_EOI without attempting to read more data.)
+
+The library's output processing will automatically call jpeg_consume_input()
+whenever the output processing overtakes the input; thus, simple lockstep
+display requires no direct calls to jpeg_consume_input().  But by adding
+calls to jpeg_consume_input(), you can absorb data in advance of what is
+being displayed.  This has two benefits:
+  * You can limit buildup of unprocessed data in your input buffer.
+  * You can eliminate extra display passes by paying attention to the
+    state of the library's input processing.
+
+The first of these benefits only requires interspersing calls to
+jpeg_consume_input() with your display operations and any other processing
+you may be doing.  To avoid wasting cycles due to backtracking, it's best to
+call jpeg_consume_input() only after a hundred or so new bytes have arrived.
+This is discussed further under "I/O suspension", above.  (Note: the JPEG
+library currently is not thread-safe.  You must not call jpeg_consume_input()
+from one thread of control if a different library routine is working on the
+same JPEG object in another thread.)
+
+When input arrives fast enough that more than one new scan is available
+before you start a new output pass, you may as well skip the output pass
+corresponding to the completed scan.  This occurs for free if you pass
+cinfo.input_scan_number as the target scan number to jpeg_start_output().
+The input_scan_number field is simply the index of the scan currently being
+consumed by the input processor.  You can ensure that this is up-to-date by
+emptying the input buffer just before calling jpeg_start_output(): call
+jpeg_consume_input() repeatedly until it returns JPEG_SUSPENDED or
+JPEG_REACHED_EOI.
+
+The target scan number passed to jpeg_start_output() is saved in the
+cinfo.output_scan_number field.  The library's output processing calls
+jpeg_consume_input() whenever the current input scan number and row within
+that scan is less than or equal to the current output scan number and row.
+Thus, input processing can "get ahead" of the output processing but is not
+allowed to "fall behind".  You can achieve several different effects by
+manipulating this interlock rule.  For example, if you pass a target scan
+number greater than the current input scan number, the output processor will
+wait until that scan starts to arrive before producing any output.  (To avoid
+an infinite loop, the target scan number is automatically reset to the last
+scan number when the end of image is reached.  Thus, if you specify a large
+target scan number, the library will just absorb the entire input file and
+then perform an output pass.  This is effectively the same as what
+jpeg_start_decompress() does when you don't select buffered-image mode.)
+When you pass a target scan number equal to the current input scan number,
+the image is displayed no faster than the current input scan arrives.  The
+final possibility is to pass a target scan number less than the current input
+scan number; this disables the input/output interlock and causes the output
+processor to simply display whatever it finds in the image buffer, without
+waiting for input.  (However, the library will not accept a target scan
+number less than one, so you can't avoid waiting for the first scan.)
+
+When data is arriving faster than the output display processing can advance
+through the image, jpeg_consume_input() will store data into the buffered
+image beyond the point at which the output processing is reading data out
+again.  If the input arrives fast enough, it may "wrap around" the buffer to
+the point where the input is more than one whole scan ahead of the output.
+If the output processing simply proceeds through its display pass without
+paying attention to the input, the effect seen on-screen is that the lower
+part of the image is one or more scans better in quality than the upper part.
+Then, when the next output scan is started, you have a choice of what target
+scan number to use.  The recommended choice is to use the current input scan
+number at that time, which implies that you've skipped the output scans
+corresponding to the input scans that were completed while you processed the
+previous output scan.  In this way, the decoder automatically adapts its
+speed to the arriving data, by skipping output scans as necessary to keep up
+with the arriving data.
+
+When using this strategy, you'll want to be sure that you perform a final
+output pass after receiving all the data; otherwise your last display may not
+be full quality across the whole screen.  So the right outer loop logic is
+something like this:
+	do {
+	    absorb any waiting input by calling jpeg_consume_input()
+	    final_pass = jpeg_input_complete(&cinfo);
+	    adjust output decompression parameters if required
+	    jpeg_start_output(&cinfo, cinfo.input_scan_number);
+	    ...
+	    jpeg_finish_output()
+	} while (! final_pass);
+rather than quitting as soon as jpeg_input_complete() returns TRUE.  This
+arrangement makes it simple to use higher-quality decoding parameters
+for the final pass.  But if you don't want to use special parameters for
+the final pass, the right loop logic is like this:
+	for (;;) {
+	    absorb any waiting input by calling jpeg_consume_input()
+	    jpeg_start_output(&cinfo, cinfo.input_scan_number);
+	    ...
+	    jpeg_finish_output()
+	    if (jpeg_input_complete(&cinfo) &&
+	        cinfo.input_scan_number == cinfo.output_scan_number)
+	      break;
+	}
+In this case you don't need to know in advance whether an output pass is to
+be the last one, so it's not necessary to have reached EOF before starting
+the final output pass; rather, what you want to test is whether the output
+pass was performed in sync with the final input scan.  This form of the loop
+will avoid an extra output pass whenever the decoder is able (or nearly able)
+to keep up with the incoming data.
+
+When the data transmission speed is high, you might begin a display pass,
+then find that much or all of the file has arrived before you can complete
+the pass.  (You can detect this by noting the JPEG_REACHED_EOI return code
+from jpeg_consume_input(), or equivalently by testing jpeg_input_complete().)
+In this situation you may wish to abort the current display pass and start a
+new one using the newly arrived information.  To do so, just call
+jpeg_finish_output() and then start a new pass with jpeg_start_output().
+
+A variant strategy is to abort and restart display if more than one complete
+scan arrives during an output pass; this can be detected by noting
+JPEG_REACHED_SOS returns and/or examining cinfo.input_scan_number.  This
+idea should be employed with caution, however, since the display process
+might never get to the bottom of the image before being aborted, resulting
+in the lower part of the screen being several passes worse than the upper.
+In most cases it's probably best to abort an output pass only if the whole
+file has arrived and you want to begin the final output pass immediately.
+
+When receiving data across a communication link, we recommend always using
+the current input scan number for the output target scan number; if a
+higher-quality final pass is to be done, it should be started (aborting any
+incomplete output pass) as soon as the end of file is received.  However,
+many other strategies are possible.  For example, the application can examine
+the parameters of the current input scan and decide whether to display it or
+not.  If the scan contains only chroma data, one might choose not to use it
+as the target scan, expecting that the scan will be small and will arrive
+quickly.  To skip to the next scan, call jpeg_consume_input() until it
+returns JPEG_REACHED_SOS or JPEG_REACHED_EOI.  Or just use the next higher
+number as the target scan for jpeg_start_output(); but that method doesn't
+let you inspect the next scan's parameters before deciding to display it.
+
+
+In buffered-image mode, jpeg_start_decompress() never performs input and
+thus never suspends.  An application that uses input suspension with
+buffered-image mode must be prepared for suspension returns from these
+routines:
+* jpeg_start_output() performs input only if you request 2-pass quantization
+  and the target scan isn't fully read yet.  (This is discussed below.)
+* jpeg_read_scanlines(), as always, returns the number of scanlines that it
+  was able to produce before suspending.
+* jpeg_finish_output() will read any markers following the target scan,
+  up to the end of the file or the SOS marker that begins another scan.
+  (But it reads no input if jpeg_consume_input() has already reached the
+  end of the file or a SOS marker beyond the target output scan.)
+* jpeg_finish_decompress() will read until the end of file, and thus can
+  suspend if the end hasn't already been reached (as can be tested by
+  calling jpeg_input_complete()).
+jpeg_start_output(), jpeg_finish_output(), and jpeg_finish_decompress()
+all return TRUE if they completed their tasks, FALSE if they had to suspend.
+In the event of a FALSE return, the application must load more input data
+and repeat the call.  Applications that use non-suspending data sources need
+not check the return values of these three routines.
+
+
+It is possible to change decoding parameters between output passes in the
+buffered-image mode.  The decoder library currently supports only very
+limited changes of parameters.  ONLY THE FOLLOWING parameter changes are
+allowed after jpeg_start_decompress() is called:
+* dct_method can be changed before each call to jpeg_start_output().
+  For example, one could use a fast DCT method for early scans, changing
+  to a higher quality method for the final scan.
+* dither_mode can be changed before each call to jpeg_start_output();
+  of course this has no impact if not using color quantization.  Typically
+  one would use ordered dither for initial passes, then switch to
+  Floyd-Steinberg dither for the final pass.  Caution: changing dither mode
+  can cause more memory to be allocated by the library.  Although the amount
+  of memory involved is not large (a scanline or so), it may cause the
+  initial max_memory_to_use specification to be exceeded, which in the worst
+  case would result in an out-of-memory failure.
+* do_block_smoothing can be changed before each call to jpeg_start_output().
+  This setting is relevant only when decoding a progressive JPEG image.
+  During the first DC-only scan, block smoothing provides a very "fuzzy" look
+  instead of the very "blocky" look seen without it; which is better seems a
+  matter of personal taste.  But block smoothing is nearly always a win
+  during later stages, especially when decoding a successive-approximation
+  image: smoothing helps to hide the slight blockiness that otherwise shows
+  up on smooth gradients until the lowest coefficient bits are sent.
+* Color quantization mode can be changed under the rules described below.
+  You *cannot* change between full-color and quantized output (because that
+  would alter the required I/O buffer sizes), but you can change which
+  quantization method is used.
+
+When generating color-quantized output, changing quantization method is a
+very useful way of switching between high-speed and high-quality display.
+The library allows you to change among its three quantization methods:
+1. Single-pass quantization to a fixed color cube.
+   Selected by cinfo.two_pass_quantize = FALSE and cinfo.colormap = NULL.
+2. Single-pass quantization to an application-supplied colormap.
+   Selected by setting cinfo.colormap to point to the colormap (the value of
+   two_pass_quantize is ignored); also set cinfo.actual_number_of_colors.
+3. Two-pass quantization to a colormap chosen specifically for the image.
+   Selected by cinfo.two_pass_quantize = TRUE and cinfo.colormap = NULL.
+   (This is the default setting selected by jpeg_read_header, but it is
+   probably NOT what you want for the first pass of progressive display!)
+These methods offer successively better quality and lesser speed.  However,
+only the first method is available for quantizing in non-RGB color spaces.
+
+IMPORTANT: because the different quantizer methods have very different
+working-storage requirements, the library requires you to indicate which
+one(s) you intend to use before you call jpeg_start_decompress().  (If we did
+not require this, the max_memory_to_use setting would be a complete fiction.)
+You do this by setting one or more of these three cinfo fields to TRUE:
+	enable_1pass_quant		Fixed color cube colormap
+	enable_external_quant		Externally-supplied colormap
+	enable_2pass_quant		Two-pass custom colormap
+All three are initialized FALSE by jpeg_read_header().  But
+jpeg_start_decompress() automatically sets TRUE the one selected by the
+current two_pass_quantize and colormap settings, so you only need to set the
+enable flags for any other quantization methods you plan to change to later.
+
+After setting the enable flags correctly at jpeg_start_decompress() time, you
+can change to any enabled quantization method by setting two_pass_quantize
+and colormap properly just before calling jpeg_start_output().  The following
+special rules apply:
+1. You must explicitly set cinfo.colormap to NULL when switching to 1-pass
+   or 2-pass mode from a different mode, or when you want the 2-pass
+   quantizer to be re-run to generate a new colormap.
+2. To switch to an external colormap, or to change to a different external
+   colormap than was used on the prior pass, you must call
+   jpeg_new_colormap() after setting cinfo.colormap.
+NOTE: if you want to use the same colormap as was used in the prior pass,
+you should not do either of these things.  This will save some nontrivial
+switchover costs.
+(These requirements exist because cinfo.colormap will always be non-NULL
+after completing a prior output pass, since both the 1-pass and 2-pass
+quantizers set it to point to their output colormaps.  Thus you have to
+do one of these two things to notify the library that something has changed.
+Yup, it's a bit klugy, but it's necessary to do it this way for backwards
+compatibility.)
+
+Note that in buffered-image mode, the library generates any requested colormap
+during jpeg_start_output(), not during jpeg_start_decompress().
+
+When using two-pass quantization, jpeg_start_output() makes a pass over the
+buffered image to determine the optimum color map; it therefore may take a
+significant amount of time, whereas ordinarily it does little work.  The
+progress monitor hook is called during this pass, if defined.  It is also
+important to realize that if the specified target scan number is greater than
+or equal to the current input scan number, jpeg_start_output() will attempt
+to consume input as it makes this pass.  If you use a suspending data source,
+you need to check for a FALSE return from jpeg_start_output() under these
+conditions.  The combination of 2-pass quantization and a not-yet-fully-read
+target scan is the only case in which jpeg_start_output() will consume input.
+
+
+Application authors who support buffered-image mode may be tempted to use it
+for all JPEG images, even single-scan ones.  This will work, but it is
+inefficient: there is no need to create an image-sized coefficient buffer for
+single-scan images.  Requesting buffered-image mode for such an image wastes
+memory.  Worse, it can cost time on large images, since the buffered data has
+to be swapped out or written to a temporary file.  If you are concerned about
+maximum performance on baseline JPEG files, you should use buffered-image
+mode only when the incoming file actually has multiple scans.  This can be
+tested by calling jpeg_has_multiple_scans(), which will return a correct
+result at any time after jpeg_read_header() completes.
+
+It is also worth noting that when you use jpeg_consume_input() to let input
+processing get ahead of output processing, the resulting pattern of access to
+the coefficient buffer is quite nonsequential.  It's best to use the memory
+manager jmemnobs.c if you can (ie, if you have enough real or virtual main
+memory).  If not, at least make sure that max_memory_to_use is set as high as
+possible.  If the JPEG memory manager has to use a temporary file, you will
+probably see a lot of disk traffic and poor performance.  (This could be
+improved with additional work on the memory manager, but we haven't gotten
+around to it yet.)
+
+In some applications it may be convenient to use jpeg_consume_input() for all
+input processing, including reading the initial markers; that is, you may
+wish to call jpeg_consume_input() instead of jpeg_read_header() during
+startup.  This works, but note that you must check for JPEG_REACHED_SOS and
+JPEG_REACHED_EOI return codes as the equivalent of jpeg_read_header's codes.
+Once the first SOS marker has been reached, you must call
+jpeg_start_decompress() before jpeg_consume_input() will consume more input;
+it'll just keep returning JPEG_REACHED_SOS until you do.  If you read a
+tables-only file this way, jpeg_consume_input() will return JPEG_REACHED_EOI
+without ever returning JPEG_REACHED_SOS; be sure to check for this case.
+If this happens, the decompressor will not read any more input until you call
+jpeg_abort() to reset it.  It is OK to call jpeg_consume_input() even when not
+using buffered-image mode, but in that case it's basically a no-op after the
+initial markers have been read: it will just return JPEG_SUSPENDED.
+
+
+Abbreviated datastreams and multiple images
+-------------------------------------------
+
+A JPEG compression or decompression object can be reused to process multiple
+images.  This saves a small amount of time per image by eliminating the
+"create" and "destroy" operations, but that isn't the real purpose of the
+feature.  Rather, reuse of an object provides support for abbreviated JPEG
+datastreams.  Object reuse can also simplify processing a series of images in
+a single input or output file.  This section explains these features.
+
+A JPEG file normally contains several hundred bytes worth of quantization
+and Huffman tables.  In a situation where many images will be stored or
+transmitted with identical tables, this may represent an annoying overhead.
+The JPEG standard therefore permits tables to be omitted.  The standard
+defines three classes of JPEG datastreams:
+  * "Interchange" datastreams contain an image and all tables needed to decode
+     the image.  These are the usual kind of JPEG file.
+  * "Abbreviated image" datastreams contain an image, but are missing some or
+    all of the tables needed to decode that image.
+  * "Abbreviated table specification" (henceforth "tables-only") datastreams
+    contain only table specifications.
+To decode an abbreviated image, it is necessary to load the missing table(s)
+into the decoder beforehand.  This can be accomplished by reading a separate
+tables-only file.  A variant scheme uses a series of images in which the first
+image is an interchange (complete) datastream, while subsequent ones are
+abbreviated and rely on the tables loaded by the first image.  It is assumed
+that once the decoder has read a table, it will remember that table until a
+new definition for the same table number is encountered.
+
+It is the application designer's responsibility to figure out how to associate
+the correct tables with an abbreviated image.  While abbreviated datastreams
+can be useful in a closed environment, their use is strongly discouraged in
+any situation where data exchange with other applications might be needed.
+Caveat designer.
+
+The JPEG library provides support for reading and writing any combination of
+tables-only datastreams and abbreviated images.  In both compression and
+decompression objects, a quantization or Huffman table will be retained for
+the lifetime of the object, unless it is overwritten by a new table definition.
+
+
+To create abbreviated image datastreams, it is only necessary to tell the
+compressor not to emit some or all of the tables it is using.  Each
+quantization and Huffman table struct contains a boolean field "sent_table",
+which normally is initialized to FALSE.  For each table used by the image, the
+header-writing process emits the table and sets sent_table = TRUE unless it is
+already TRUE.  (In normal usage, this prevents outputting the same table
+definition multiple times, as would otherwise occur because the chroma
+components typically share tables.)  Thus, setting this field to TRUE before
+calling jpeg_start_compress() will prevent the table from being written at
+all.
+
+If you want to create a "pure" abbreviated image file containing no tables,
+just call "jpeg_suppress_tables(&cinfo, TRUE)" after constructing all the
+tables.  If you want to emit some but not all tables, you'll need to set the
+individual sent_table fields directly.
+
+To create an abbreviated image, you must also call jpeg_start_compress()
+with a second parameter of FALSE, not TRUE.  Otherwise jpeg_start_compress()
+will force all the sent_table fields to FALSE.  (This is a safety feature to
+prevent abbreviated images from being created accidentally.)
+
+To create a tables-only file, perform the same parameter setup that you
+normally would, but instead of calling jpeg_start_compress() and so on, call
+jpeg_write_tables(&cinfo).  This will write an abbreviated datastream
+containing only SOI, DQT and/or DHT markers, and EOI.  All the quantization
+and Huffman tables that are currently defined in the compression object will
+be emitted unless their sent_tables flag is already TRUE, and then all the
+sent_tables flags will be set TRUE.
+
+A sure-fire way to create matching tables-only and abbreviated image files
+is to proceed as follows:
+
+	create JPEG compression object
+	set JPEG parameters
+	set destination to tables-only file
+	jpeg_write_tables(&cinfo);
+	set destination to image file
+	jpeg_start_compress(&cinfo, FALSE);
+	write data...
+	jpeg_finish_compress(&cinfo);
+
+Since the JPEG parameters are not altered between writing the table file and
+the abbreviated image file, the same tables are sure to be used.  Of course,
+you can repeat the jpeg_start_compress() ... jpeg_finish_compress() sequence
+many times to produce many abbreviated image files matching the table file.
+
+You cannot suppress output of the computed Huffman tables when Huffman
+optimization is selected.  (If you could, there'd be no way to decode the
+image...)  Generally, you don't want to set optimize_coding = TRUE when
+you are trying to produce abbreviated files.
+
+In some cases you might want to compress an image using tables which are
+not stored in the application, but are defined in an interchange or
+tables-only file readable by the application.  This can be done by setting up
+a JPEG decompression object to read the specification file, then copying the
+tables into your compression object.  See jpeg_copy_critical_parameters()
+for an example of copying quantization tables.
+
+
+To read abbreviated image files, you simply need to load the proper tables
+into the decompression object before trying to read the abbreviated image.
+If the proper tables are stored in the application program, you can just
+allocate the table structs and fill in their contents directly.  For example,
+to load a fixed quantization table into table slot "n":
+
+    if (cinfo.quant_tbl_ptrs[n] == NULL)
+      cinfo.quant_tbl_ptrs[n] = jpeg_alloc_quant_table((j_common_ptr) &cinfo);
+    quant_ptr = cinfo.quant_tbl_ptrs[n];	/* quant_ptr is JQUANT_TBL* */
+    for (i = 0; i < 64; i++) {
+      /* Qtable[] is desired quantization table, in natural array order */
+      quant_ptr->quantval[i] = Qtable[i];
+    }
+
+Code to load a fixed Huffman table is typically (for AC table "n"):
+
+    if (cinfo.ac_huff_tbl_ptrs[n] == NULL)
+      cinfo.ac_huff_tbl_ptrs[n] = jpeg_alloc_huff_table((j_common_ptr) &cinfo);
+    huff_ptr = cinfo.ac_huff_tbl_ptrs[n];	/* huff_ptr is JHUFF_TBL* */
+    for (i = 1; i <= 16; i++) {
+      /* counts[i] is number of Huffman codes of length i bits, i=1..16 */
+      huff_ptr->bits[i] = counts[i];
+    }
+    for (i = 0; i < 256; i++) {
+      /* symbols[] is the list of Huffman symbols, in code-length order */
+      huff_ptr->huffval[i] = symbols[i];
+    }
+
+(Note that trying to set cinfo.quant_tbl_ptrs[n] to point directly at a
+constant JQUANT_TBL object is not safe.  If the incoming file happened to
+contain a quantization table definition, your master table would get
+overwritten!  Instead allocate a working table copy and copy the master table
+into it, as illustrated above.  Ditto for Huffman tables, of course.)
+
+You might want to read the tables from a tables-only file, rather than
+hard-wiring them into your application.  The jpeg_read_header() call is
+sufficient to read a tables-only file.  You must pass a second parameter of
+FALSE to indicate that you do not require an image to be present.  Thus, the
+typical scenario is
+
+	create JPEG decompression object
+	set source to tables-only file
+	jpeg_read_header(&cinfo, FALSE);
+	set source to abbreviated image file
+	jpeg_read_header(&cinfo, TRUE);
+	set decompression parameters
+	jpeg_start_decompress(&cinfo);
+	read data...
+	jpeg_finish_decompress(&cinfo);
+
+In some cases, you may want to read a file without knowing whether it contains
+an image or just tables.  In that case, pass FALSE and check the return value
+from jpeg_read_header(): it will be JPEG_HEADER_OK if an image was found,
+JPEG_HEADER_TABLES_ONLY if only tables were found.  (A third return value,
+JPEG_SUSPENDED, is possible when using a suspending data source manager.)
+Note that jpeg_read_header() will not complain if you read an abbreviated
+image for which you haven't loaded the missing tables; the missing-table check
+occurs later, in jpeg_start_decompress().
+
+
+It is possible to read a series of images from a single source file by
+repeating the jpeg_read_header() ... jpeg_finish_decompress() sequence,
+without releasing/recreating the JPEG object or the data source module.
+(If you did reinitialize, any partial bufferload left in the data source
+buffer at the end of one image would be discarded, causing you to lose the
+start of the next image.)  When you use this method, stored tables are
+automatically carried forward, so some of the images can be abbreviated images
+that depend on tables from earlier images.
+
+If you intend to write a series of images into a single destination file,
+you might want to make a specialized data destination module that doesn't
+flush the output buffer at term_destination() time.  This would speed things
+up by some trifling amount.  Of course, you'd need to remember to flush the
+buffer after the last image.  You can make the later images be abbreviated
+ones by passing FALSE to jpeg_start_compress().
+
+
+Special markers
+---------------
+
+Some applications may need to insert or extract special data in the JPEG
+datastream.  The JPEG standard provides marker types "COM" (comment) and
+"APP0" through "APP15" (application) to hold application-specific data.
+Unfortunately, the use of these markers is not specified by the standard.
+COM markers are fairly widely used to hold user-supplied text.  The JFIF file
+format spec uses APP0 markers with specified initial strings to hold certain
+data.  Adobe applications use APP14 markers beginning with the string "Adobe"
+for miscellaneous data.  Other APPn markers are rarely seen, but might
+contain almost anything.
+
+If you wish to store user-supplied text, we recommend you use COM markers
+and place readable 7-bit ASCII text in them.  Newline conventions are not
+standardized --- expect to find LF (Unix style), CR/LF (DOS style), or CR
+(Mac style).  A robust COM reader should be able to cope with random binary
+garbage, including nulls, since some applications generate COM markers
+containing non-ASCII junk.  (But yours should not be one of them.)
+
+For program-supplied data, use an APPn marker, and be sure to begin it with an
+identifying string so that you can tell whether the marker is actually yours.
+It's probably best to avoid using APP0 or APP14 for any private markers.
+(NOTE: the upcoming SPIFF standard will use APP8 markers; we recommend you
+not use APP8 markers for any private purposes, either.)
+
+Keep in mind that at most 65533 bytes can be put into one marker, but you
+can have as many markers as you like.
+
+By default, the IJG compression library will write a JFIF APP0 marker if the
+selected JPEG colorspace is grayscale or YCbCr, or an Adobe APP14 marker if
+the selected colorspace is RGB, CMYK, or YCCK.  You can disable this, but
+we don't recommend it.  The decompression library will recognize JFIF and
+Adobe markers and will set the JPEG colorspace properly when one is found.
+
+
+You can write special markers immediately following the datastream header by
+calling jpeg_write_marker() after jpeg_start_compress() and before the first
+call to jpeg_write_scanlines().  When you do this, the markers appear after
+the SOI and the JFIF APP0 and Adobe APP14 markers (if written), but before
+all else.  Specify the marker type parameter as "JPEG_COM" for COM or
+"JPEG_APP0 + n" for APPn.  (Actually, jpeg_write_marker will let you write
+any marker type, but we don't recommend writing any other kinds of marker.)
+For example, to write a user comment string pointed to by comment_text:
+	jpeg_write_marker(cinfo, JPEG_COM, comment_text, strlen(comment_text));
+
+If it's not convenient to store all the marker data in memory at once,
+you can instead call jpeg_write_m_header() followed by multiple calls to
+jpeg_write_m_byte().  If you do it this way, it's your responsibility to
+call jpeg_write_m_byte() exactly the number of times given in the length
+parameter to jpeg_write_m_header().  (This method lets you empty the
+output buffer partway through a marker, which might be important when
+using a suspending data destination module.  In any case, if you are using
+a suspending destination, you should flush its buffer after inserting
+any special markers.  See "I/O suspension".)
+
+Or, if you prefer to synthesize the marker byte sequence yourself,
+you can just cram it straight into the data destination module.
+
+If you are writing JFIF 1.02 extension markers (thumbnail images), don't
+forget to set cinfo.JFIF_minor_version = 2 so that the encoder will write the
+correct JFIF version number in the JFIF header marker.  The library's default
+is to write version 1.01, but that's wrong if you insert any 1.02 extension
+markers.  (We could probably get away with just defaulting to 1.02, but there
+used to be broken decoders that would complain about unknown minor version
+numbers.  To reduce compatibility risks it's safest not to write 1.02 unless
+you are actually using 1.02 extensions.)
+
+
+When reading, two methods of handling special markers are available:
+1. You can ask the library to save the contents of COM and/or APPn markers
+into memory, and then examine them at your leisure afterwards.
+2. You can supply your own routine to process COM and/or APPn markers
+on-the-fly as they are read.
+The first method is simpler to use, especially if you are using a suspending
+data source; writing a marker processor that copes with input suspension is
+not easy (consider what happens if the marker is longer than your available
+input buffer).  However, the second method conserves memory since the marker
+data need not be kept around after it's been processed.
+
+For either method, you'd normally set up marker handling after creating a
+decompression object and before calling jpeg_read_header(), because the
+markers of interest will typically be near the head of the file and so will
+be scanned by jpeg_read_header.  Once you've established a marker handling
+method, it will be used for the life of that decompression object
+(potentially many datastreams), unless you change it.  Marker handling is
+determined separately for COM markers and for each APPn marker code.
+
+
+To save the contents of special markers in memory, call
+	jpeg_save_markers(cinfo, marker_code, length_limit)
+where marker_code is the marker type to save, JPEG_COM or JPEG_APP0+n.
+(To arrange to save all the special marker types, you need to call this
+routine 17 times, for COM and APP0-APP15.)  If the incoming marker is longer
+than length_limit data bytes, only length_limit bytes will be saved; this
+parameter allows you to avoid chewing up memory when you only need to see the
+first few bytes of a potentially large marker.  If you want to save all the
+data, set length_limit to 0xFFFF; that is enough since marker lengths are only
+16 bits.  As a special case, setting length_limit to 0 prevents that marker
+type from being saved at all.  (That is the default behavior, in fact.)
+
+After jpeg_read_header() completes, you can examine the special markers by
+following the cinfo->marker_list pointer chain.  All the special markers in
+the file appear in this list, in order of their occurrence in the file (but
+omitting any markers of types you didn't ask for).  Both the original data
+length and the saved data length are recorded for each list entry; the latter
+will not exceed length_limit for the particular marker type.  Note that these
+lengths exclude the marker length word, whereas the stored representation
+within the JPEG file includes it.  (Hence the maximum data length is really
+only 65533.)
+
+It is possible that additional special markers appear in the file beyond the
+SOS marker at which jpeg_read_header stops; if so, the marker list will be
+extended during reading of the rest of the file.  This is not expected to be
+common, however.  If you are short on memory you may want to reset the length
+limit to zero for all marker types after finishing jpeg_read_header, to
+ensure that the max_memory_to_use setting cannot be exceeded due to addition
+of later markers.
+
+The marker list remains stored until you call jpeg_finish_decompress or
+jpeg_abort, at which point the memory is freed and the list is set to empty.
+(jpeg_destroy also releases the storage, of course.)
+
+Note that the library is internally interested in APP0 and APP14 markers;
+if you try to set a small nonzero length limit on these types, the library
+will silently force the length up to the minimum it wants.  (But you can set
+a zero length limit to prevent them from being saved at all.)  Also, in a
+16-bit environment, the maximum length limit may be constrained to less than
+65533 by malloc() limitations.  It is therefore best not to assume that the
+effective length limit is exactly what you set it to be.
+
+
+If you want to supply your own marker-reading routine, you do it by calling
+jpeg_set_marker_processor().  A marker processor routine must have the
+signature
+	boolean jpeg_marker_parser_method (j_decompress_ptr cinfo)
+Although the marker code is not explicitly passed, the routine can find it
+in cinfo->unread_marker.  At the time of call, the marker proper has been
+read from the data source module.  The processor routine is responsible for
+reading the marker length word and the remaining parameter bytes, if any.
+Return TRUE to indicate success.  (FALSE should be returned only if you are
+using a suspending data source and it tells you to suspend.  See the standard
+marker processors in jdmarker.c for appropriate coding methods if you need to
+use a suspending data source.)
+
+If you override the default APP0 or APP14 processors, it is up to you to
+recognize JFIF and Adobe markers if you want colorspace recognition to occur
+properly.  We recommend copying and extending the default processors if you
+want to do that.  (A better idea is to save these marker types for later
+examination by calling jpeg_save_markers(); that method doesn't interfere
+with the library's own processing of these markers.)
+
+jpeg_set_marker_processor() and jpeg_save_markers() are mutually exclusive
+--- if you call one it overrides any previous call to the other, for the
+particular marker type specified.
+
+A simple example of an external COM processor can be found in djpeg.c.
+Also, see jpegtran.c for an example of using jpeg_save_markers.
+
+
+Raw (downsampled) image data
+----------------------------
+
+Some applications need to supply already-downsampled image data to the JPEG
+compressor, or to receive raw downsampled data from the decompressor.  The
+library supports this requirement by allowing the application to write or
+read raw data, bypassing the normal preprocessing or postprocessing steps.
+The interface is different from the standard one and is somewhat harder to
+use.  If your interest is merely in bypassing color conversion, we recommend
+that you use the standard interface and simply set jpeg_color_space =
+in_color_space (or jpeg_color_space = out_color_space for decompression).
+The mechanism described in this section is necessary only to supply or
+receive downsampled image data, in which not all components have the same
+dimensions.
+
+
+To compress raw data, you must supply the data in the colorspace to be used
+in the JPEG file (please read the earlier section on Special color spaces)
+and downsampled to the sampling factors specified in the JPEG parameters.
+You must supply the data in the format used internally by the JPEG library,
+namely a JSAMPIMAGE array.  This is an array of pointers to two-dimensional
+arrays, each of type JSAMPARRAY.  Each 2-D array holds the values for one
+color component.  This structure is necessary since the components are of
+different sizes.  If the image dimensions are not a multiple of the MCU size,
+you must also pad the data correctly (usually, this is done by replicating
+the last column and/or row).  The data must be padded to a multiple of a DCT
+block in each component: that is, each downsampled row must contain a
+multiple of 8 valid samples, and there must be a multiple of 8 sample rows
+for each component.  (For applications such as conversion of digital TV
+images, the standard image size is usually a multiple of the DCT block size,
+so that no padding need actually be done.)
+
+The procedure for compression of raw data is basically the same as normal
+compression, except that you call jpeg_write_raw_data() in place of
+jpeg_write_scanlines().  Before calling jpeg_start_compress(), you must do
+the following:
+  * Set cinfo->raw_data_in to TRUE.  (It is set FALSE by jpeg_set_defaults().)
+    This notifies the library that you will be supplying raw data.
+  * Ensure jpeg_color_space is correct --- an explicit jpeg_set_colorspace()
+    call is a good idea.  Note that since color conversion is bypassed,
+    in_color_space is ignored, except that jpeg_set_defaults() uses it to
+    choose the default jpeg_color_space setting.
+  * Ensure the sampling factors, cinfo->comp_info[i].h_samp_factor and
+    cinfo->comp_info[i].v_samp_factor, are correct.  Since these indicate the
+    dimensions of the data you are supplying, it's wise to set them
+    explicitly, rather than assuming the library's defaults are what you want.
+
+To pass raw data to the library, call jpeg_write_raw_data() in place of
+jpeg_write_scanlines().  The two routines work similarly except that
+jpeg_write_raw_data takes a JSAMPIMAGE data array rather than JSAMPARRAY.
+The scanlines count passed to and returned from jpeg_write_raw_data is
+measured in terms of the component with the largest v_samp_factor.
+
+jpeg_write_raw_data() processes one MCU row per call, which is to say
+v_samp_factor*DCTSIZE sample rows of each component.  The passed num_lines
+value must be at least max_v_samp_factor*DCTSIZE, and the return value will
+be exactly that amount (or possibly some multiple of that amount, in future
+library versions).  This is true even on the last call at the bottom of the
+image; don't forget to pad your data as necessary.
+
+The required dimensions of the supplied data can be computed for each
+component as
+	cinfo->comp_info[i].width_in_blocks*DCTSIZE  samples per row
+	cinfo->comp_info[i].height_in_blocks*DCTSIZE rows in image
+after jpeg_start_compress() has initialized those fields.  If the valid data
+is smaller than this, it must be padded appropriately.  For some sampling
+factors and image sizes, additional dummy DCT blocks are inserted to make
+the image a multiple of the MCU dimensions.  The library creates such dummy
+blocks itself; it does not read them from your supplied data.  Therefore you
+need never pad by more than DCTSIZE samples.  An example may help here.
+Assume 2h2v downsampling of YCbCr data, that is
+	cinfo->comp_info[0].h_samp_factor = 2		for Y
+	cinfo->comp_info[0].v_samp_factor = 2
+	cinfo->comp_info[1].h_samp_factor = 1		for Cb
+	cinfo->comp_info[1].v_samp_factor = 1
+	cinfo->comp_info[2].h_samp_factor = 1		for Cr
+	cinfo->comp_info[2].v_samp_factor = 1
+and suppose that the nominal image dimensions (cinfo->image_width and
+cinfo->image_height) are 101x101 pixels.  Then jpeg_start_compress() will
+compute downsampled_width = 101 and width_in_blocks = 13 for Y,
+downsampled_width = 51 and width_in_blocks = 7 for Cb and Cr (and the same
+for the height fields).  You must pad the Y data to at least 13*8 = 104
+columns and rows, the Cb/Cr data to at least 7*8 = 56 columns and rows.  The
+MCU height is max_v_samp_factor = 2 DCT rows so you must pass at least 16
+scanlines on each call to jpeg_write_raw_data(), which is to say 16 actual
+sample rows of Y and 8 each of Cb and Cr.  A total of 7 MCU rows are needed,
+so you must pass a total of 7*16 = 112 "scanlines".  The last DCT block row
+of Y data is dummy, so it doesn't matter what you pass for it in the data
+arrays, but the scanlines count must total up to 112 so that all of the Cb
+and Cr data gets passed.
+
+Output suspension is supported with raw-data compression: if the data
+destination module suspends, jpeg_write_raw_data() will return 0.
+In this case the same data rows must be passed again on the next call.
+
+
+Decompression with raw data output implies bypassing all postprocessing:
+you cannot ask for rescaling or color quantization, for instance.  More
+seriously, you must deal with the color space and sampling factors present in
+the incoming file.  If your application only handles, say, 2h1v YCbCr data,
+you must check for and fail on other color spaces or other sampling factors.
+The library will not convert to a different color space for you.
+
+To obtain raw data output, set cinfo->raw_data_out = TRUE before
+jpeg_start_decompress() (it is set FALSE by jpeg_read_header()).  Be sure to
+verify that the color space and sampling factors are ones you can handle.
+Then call jpeg_read_raw_data() in place of jpeg_read_scanlines().  The
+decompression process is otherwise the same as usual.
+
+jpeg_read_raw_data() returns one MCU row per call, and thus you must pass a
+buffer of at least max_v_samp_factor*DCTSIZE scanlines (scanline counting is
+the same as for raw-data compression).  The buffer you pass must be large
+enough to hold the actual data plus padding to DCT-block boundaries.  As with
+compression, any entirely dummy DCT blocks are not processed so you need not
+allocate space for them, but the total scanline count includes them.  The
+above example of computing buffer dimensions for raw-data compression is
+equally valid for decompression.
+
+Input suspension is supported with raw-data decompression: if the data source
+module suspends, jpeg_read_raw_data() will return 0.  You can also use
+buffered-image mode to read raw data in multiple passes.
+
+
+Really raw data: DCT coefficients
+---------------------------------
+
+It is possible to read or write the contents of a JPEG file as raw DCT
+coefficients.  This facility is mainly intended for use in lossless
+transcoding between different JPEG file formats.  Other possible applications
+include lossless cropping of a JPEG image, lossless reassembly of a
+multi-strip or multi-tile TIFF/JPEG file into a single JPEG datastream, etc.
+
+To read the contents of a JPEG file as DCT coefficients, open the file and do
+jpeg_read_header() as usual.  But instead of calling jpeg_start_decompress()
+and jpeg_read_scanlines(), call jpeg_read_coefficients().  This will read the
+entire image into a set of virtual coefficient-block arrays, one array per
+component.  The return value is a pointer to an array of virtual-array
+descriptors.  Each virtual array can be accessed directly using the JPEG
+memory manager's access_virt_barray method (see Memory management, below,
+and also read structure.doc's discussion of virtual array handling).  Or,
+for simple transcoding to a different JPEG file format, the array list can
+just be handed directly to jpeg_write_coefficients().
+
+Each block in the block arrays contains quantized coefficient values in
+normal array order (not JPEG zigzag order).  The block arrays contain only
+DCT blocks containing real data; any entirely-dummy blocks added to fill out
+interleaved MCUs at the right or bottom edges of the image are discarded
+during reading and are not stored in the block arrays.  (The size of each
+block array can be determined from the width_in_blocks and height_in_blocks
+fields of the component's comp_info entry.)  This is also the data format
+expected by jpeg_write_coefficients().
+
+When you are done using the virtual arrays, call jpeg_finish_decompress()
+to release the array storage and return the decompression object to an idle
+state; or just call jpeg_destroy() if you don't need to reuse the object.
+
+If you use a suspending data source, jpeg_read_coefficients() will return
+NULL if it is forced to suspend; a non-NULL return value indicates successful
+completion.  You need not test for a NULL return value when using a
+non-suspending data source.
+
+It is also possible to call jpeg_read_coefficients() to obtain access to the
+decoder's coefficient arrays during a normal decode cycle in buffered-image
+mode.  This frammish might be useful for progressively displaying an incoming
+image and then re-encoding it without loss.  To do this, decode in buffered-
+image mode as discussed previously, then call jpeg_read_coefficients() after
+the last jpeg_finish_output() call.  The arrays will be available for your use
+until you call jpeg_finish_decompress().
+
+
+To write the contents of a JPEG file as DCT coefficients, you must provide
+the DCT coefficients stored in virtual block arrays.  You can either pass
+block arrays read from an input JPEG file by jpeg_read_coefficients(), or
+allocate virtual arrays from the JPEG compression object and fill them
+yourself.  In either case, jpeg_write_coefficients() is substituted for
+jpeg_start_compress() and jpeg_write_scanlines().  Thus the sequence is
+  * Create compression object
+  * Set all compression parameters as necessary
+  * Request virtual arrays if needed
+  * jpeg_write_coefficients()
+  * jpeg_finish_compress()
+  * Destroy or re-use compression object
+jpeg_write_coefficients() is passed a pointer to an array of virtual block
+array descriptors; the number of arrays is equal to cinfo.num_components.
+
+The virtual arrays need only have been requested, not realized, before
+jpeg_write_coefficients() is called.  A side-effect of
+jpeg_write_coefficients() is to realize any virtual arrays that have been
+requested from the compression object's memory manager.  Thus, when obtaining
+the virtual arrays from the compression object, you should fill the arrays
+after calling jpeg_write_coefficients().  The data is actually written out
+when you call jpeg_finish_compress(); jpeg_write_coefficients() only writes
+the file header.
+
+When writing raw DCT coefficients, it is crucial that the JPEG quantization
+tables and sampling factors match the way the data was encoded, or the
+resulting file will be invalid.  For transcoding from an existing JPEG file,
+we recommend using jpeg_copy_critical_parameters().  This routine initializes
+all the compression parameters to default values (like jpeg_set_defaults()),
+then copies the critical information from a source decompression object.
+The decompression object should have just been used to read the entire
+JPEG input file --- that is, it should be awaiting jpeg_finish_decompress().
+
+jpeg_write_coefficients() marks all tables stored in the compression object
+as needing to be written to the output file (thus, it acts like
+jpeg_start_compress(cinfo, TRUE)).  This is for safety's sake, to avoid
+emitting abbreviated JPEG files by accident.  If you really want to emit an
+abbreviated JPEG file, call jpeg_suppress_tables(), or set the tables'
+individual sent_table flags, between calling jpeg_write_coefficients() and
+jpeg_finish_compress().
+
+
+Progress monitoring
+-------------------
+
+Some applications may need to regain control from the JPEG library every so
+often.  The typical use of this feature is to produce a percent-done bar or
+other progress display.  (For a simple example, see cjpeg.c or djpeg.c.)
+Although you do get control back frequently during the data-transferring pass
+(the jpeg_read_scanlines or jpeg_write_scanlines loop), any additional passes
+will occur inside jpeg_finish_compress or jpeg_start_decompress; those
+routines may take a long time to execute, and you don't get control back
+until they are done.
+
+You can define a progress-monitor routine which will be called periodically
+by the library.  No guarantees are made about how often this call will occur,
+so we don't recommend you use it for mouse tracking or anything like that.
+At present, a call will occur once per MCU row, scanline, or sample row
+group, whichever unit is convenient for the current processing mode; so the
+wider the image, the longer the time between calls.  During the data
+transferring pass, only one call occurs per call of jpeg_read_scanlines or
+jpeg_write_scanlines, so don't pass a large number of scanlines at once if
+you want fine resolution in the progress count.  (If you really need to use
+the callback mechanism for time-critical tasks like mouse tracking, you could
+insert additional calls inside some of the library's inner loops.)
+
+To establish a progress-monitor callback, create a struct jpeg_progress_mgr,
+fill in its progress_monitor field with a pointer to your callback routine,
+and set cinfo->progress to point to the struct.  The callback will be called
+whenever cinfo->progress is non-NULL.  (This pointer is set to NULL by
+jpeg_create_compress or jpeg_create_decompress; the library will not change
+it thereafter.  So if you allocate dynamic storage for the progress struct,
+make sure it will live as long as the JPEG object does.  Allocating from the
+JPEG memory manager with lifetime JPOOL_PERMANENT will work nicely.)  You
+can use the same callback routine for both compression and decompression.
+
+The jpeg_progress_mgr struct contains four fields which are set by the library:
+	long pass_counter;	/* work units completed in this pass */
+	long pass_limit;	/* total number of work units in this pass */
+	int completed_passes;	/* passes completed so far */
+	int total_passes;	/* total number of passes expected */
+During any one pass, pass_counter increases from 0 up to (not including)
+pass_limit; the step size is usually but not necessarily 1.  The pass_limit
+value may change from one pass to another.  The expected total number of
+passes is in total_passes, and the number of passes already completed is in
+completed_passes.  Thus the fraction of work completed may be estimated as
+		completed_passes + (pass_counter/pass_limit)
+		--------------------------------------------
+				total_passes
+ignoring the fact that the passes may not be equal amounts of work.
+
+When decompressing, pass_limit can even change within a pass, because it
+depends on the number of scans in the JPEG file, which isn't always known in
+advance.  The computed fraction-of-work-done may jump suddenly (if the library
+discovers it has overestimated the number of scans) or even decrease (in the
+opposite case).  It is not wise to put great faith in the work estimate.
+
+When using the decompressor's buffered-image mode, the progress monitor work
+estimate is likely to be completely unhelpful, because the library has no way
+to know how many output passes will be demanded of it.  Currently, the library
+sets total_passes based on the assumption that there will be one more output
+pass if the input file end hasn't yet been read (jpeg_input_complete() isn't
+TRUE), but no more output passes if the file end has been reached when the
+output pass is started.  This means that total_passes will rise as additional
+output passes are requested.  If you have a way of determining the input file
+size, estimating progress based on the fraction of the file that's been read
+will probably be more useful than using the library's value.
+
+
+Memory management
+-----------------
+
+This section covers some key facts about the JPEG library's built-in memory
+manager.  For more info, please read structure.doc's section about the memory
+manager, and consult the source code if necessary.
+
+All memory and temporary file allocation within the library is done via the
+memory manager.  If necessary, you can replace the "back end" of the memory
+manager to control allocation yourself (for example, if you don't want the
+library to use malloc() and free() for some reason).
+
+Some data is allocated "permanently" and will not be freed until the JPEG
+object is destroyed.  Most data is allocated "per image" and is freed by
+jpeg_finish_compress, jpeg_finish_decompress, or jpeg_abort.  You can call the
+memory manager yourself to allocate structures that will automatically be
+freed at these times.  Typical code for this is
+  ptr = (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, size);
+Use JPOOL_PERMANENT to get storage that lasts as long as the JPEG object.
+Use alloc_large instead of alloc_small for anything bigger than a few Kbytes.
+There are also alloc_sarray and alloc_barray routines that automatically
+build 2-D sample or block arrays.
+
+The library's minimum space requirements to process an image depend on the
+image's width, but not on its height, because the library ordinarily works
+with "strip" buffers that are as wide as the image but just a few rows high.
+Some operating modes (eg, two-pass color quantization) require full-image
+buffers.  Such buffers are treated as "virtual arrays": only the current strip
+need be in memory, and the rest can be swapped out to a temporary file.
+
+If you use the simplest memory manager back end (jmemnobs.c), then no
+temporary files are used; virtual arrays are simply malloc()'d.  Images bigger
+than memory can be processed only if your system supports virtual memory.
+The other memory manager back ends support temporary files of various flavors
+and thus work in machines without virtual memory.  They may also be useful on
+Unix machines if you need to process images that exceed available swap space.
+
+When using temporary files, the library will make the in-memory buffers for
+its virtual arrays just big enough to stay within a "maximum memory" setting.
+Your application can set this limit by setting cinfo->mem->max_memory_to_use
+after creating the JPEG object.  (Of course, there is still a minimum size for
+the buffers, so the max-memory setting is effective only if it is bigger than
+the minimum space needed.)  If you allocate any large structures yourself, you
+must allocate them before jpeg_start_compress() or jpeg_start_decompress() in
+order to have them counted against the max memory limit.  Also keep in mind
+that space allocated with alloc_small() is ignored, on the assumption that
+it's too small to be worth worrying about; so a reasonable safety margin
+should be left when setting max_memory_to_use.
+
+If you use the jmemname.c or jmemdos.c memory manager back end, it is
+important to clean up the JPEG object properly to ensure that the temporary
+files get deleted.  (This is especially crucial with jmemdos.c, where the
+"temporary files" may be extended-memory segments; if they are not freed,
+DOS will require a reboot to recover the memory.)  Thus, with these memory
+managers, it's a good idea to provide a signal handler that will trap any
+early exit from your program.  The handler should call either jpeg_abort()
+or jpeg_destroy() for any active JPEG objects.  A handler is not needed with
+jmemnobs.c, and shouldn't be necessary with jmemansi.c or jmemmac.c either,
+since the C library is supposed to take care of deleting files made with
+tmpfile().
+
+
+Memory usage
+------------
+
+Working memory requirements while performing compression or decompression
+depend on image dimensions, image characteristics (such as colorspace and
+JPEG process), and operating mode (application-selected options).
+
+As of v6b, the decompressor requires:
+ 1. About 24K in more-or-less-fixed-size data.  This varies a bit depending
+    on operating mode and image characteristics (particularly color vs.
+    grayscale), but it doesn't depend on image dimensions.
+ 2. Strip buffers (of size proportional to the image width) for IDCT and
+    upsampling results.  The worst case for commonly used sampling factors
+    is about 34 bytes * width in pixels for a color image.  A grayscale image
+    only needs about 8 bytes per pixel column.
+ 3. A full-image DCT coefficient buffer is needed to decode a multi-scan JPEG
+    file (including progressive JPEGs), or whenever you select buffered-image
+    mode.  This takes 2 bytes/coefficient.  At typical 2x2 sampling, that's
+    3 bytes per pixel for a color image.  Worst case (1x1 sampling) requires
+    6 bytes/pixel.  For grayscale, figure 2 bytes/pixel.
+ 4. To perform 2-pass color quantization, the decompressor also needs a
+    128K color lookup table and a full-image pixel buffer (3 bytes/pixel).
+This does not count any memory allocated by the application, such as a
+buffer to hold the final output image.
+
+The above figures are valid for 8-bit JPEG data precision and a machine with
+32-bit ints.  For 12-bit JPEG data, double the size of the strip buffers and
+quantization pixel buffer.  The "fixed-size" data will be somewhat smaller
+with 16-bit ints, larger with 64-bit ints.  Also, CMYK or other unusual
+color spaces will require different amounts of space.
+
+The full-image coefficient and pixel buffers, if needed at all, do not
+have to be fully RAM resident; you can have the library use temporary
+files instead when the total memory usage would exceed a limit you set.
+(But if your OS supports virtual memory, it's probably better to just use
+jmemnobs and let the OS do the swapping.)
+
+The compressor's memory requirements are similar, except that it has no need
+for color quantization.  Also, it needs a full-image DCT coefficient buffer
+if Huffman-table optimization is asked for, even if progressive mode is not
+requested.
+
+If you need more detailed information about memory usage in a particular
+situation, you can enable the MEM_STATS code in jmemmgr.c.
+
+
+Library compile-time options
+----------------------------
+
+A number of compile-time options are available by modifying jmorecfg.h.
+
+The JPEG standard provides for both the baseline 8-bit DCT process and
+a 12-bit DCT process.  The IJG code supports 12-bit lossy JPEG if you define
+BITS_IN_JSAMPLE as 12 rather than 8.  Note that this causes JSAMPLE to be
+larger than a char, so it affects the surrounding application's image data.
+The sample applications cjpeg and djpeg can support 12-bit mode only for PPM
+and GIF file formats; you must disable the other file formats to compile a
+12-bit cjpeg or djpeg.  (install.doc has more information about that.)
+At present, a 12-bit library can handle *only* 12-bit images, not both
+precisions.  (If you need to include both 8- and 12-bit libraries in a single
+application, you could probably do it by defining NEED_SHORT_EXTERNAL_NAMES
+for just one of the copies.  You'd have to access the 8-bit and 12-bit copies
+from separate application source files.  This is untested ... if you try it,
+we'd like to hear whether it works!)
+
+Note that a 12-bit library always compresses in Huffman optimization mode,
+in order to generate valid Huffman tables.  This is necessary because our
+default Huffman tables only cover 8-bit data.  If you need to output 12-bit
+files in one pass, you'll have to supply suitable default Huffman tables.
+You may also want to supply your own DCT quantization tables; the existing
+quality-scaling code has been developed for 8-bit use, and probably doesn't
+generate especially good tables for 12-bit.
+
+The maximum number of components (color channels) in the image is determined
+by MAX_COMPONENTS.  The JPEG standard allows up to 255 components, but we
+expect that few applications will need more than four or so.
+
+On machines with unusual data type sizes, you may be able to improve
+performance or reduce memory space by tweaking the various typedefs in
+jmorecfg.h.  In particular, on some RISC CPUs, access to arrays of "short"s
+is quite slow; consider trading memory for speed by making JCOEF, INT16, and
+UINT16 be "int" or "unsigned int".  UINT8 is also a candidate to become int.
+You probably don't want to make JSAMPLE be int unless you have lots of memory
+to burn.
+
+You can reduce the size of the library by compiling out various optional
+functions.  To do this, undefine xxx_SUPPORTED symbols as necessary.
+
+You can also save a few K by not having text error messages in the library;
+the standard error message table occupies about 5Kb.  This is particularly
+reasonable for embedded applications where there's no good way to display 
+a message anyway.  To do this, remove the creation of the message table
+(jpeg_std_message_table[]) from jerror.c, and alter format_message to do
+something reasonable without it.  You could output the numeric value of the
+message code number, for example.  If you do this, you can also save a couple
+more K by modifying the TRACEMSn() macros in jerror.h to expand to nothing;
+you don't need trace capability anyway, right?
+
+
+Portability considerations
+--------------------------
+
+The JPEG library has been written to be extremely portable; the sample
+applications cjpeg and djpeg are slightly less so.  This section summarizes
+the design goals in this area.  (If you encounter any bugs that cause the
+library to be less portable than is claimed here, we'd appreciate hearing
+about them.)
+
+The code works fine on ANSI C, C++, and pre-ANSI C compilers, using any of
+the popular system include file setups, and some not-so-popular ones too.
+See install.doc for configuration procedures.
+
+The code is not dependent on the exact sizes of the C data types.  As
+distributed, we make the assumptions that
+	char	is at least 8 bits wide
+	short	is at least 16 bits wide
+	int	is at least 16 bits wide
+	long	is at least 32 bits wide
+(These are the minimum requirements of the ANSI C standard.)  Wider types will
+work fine, although memory may be used inefficiently if char is much larger
+than 8 bits or short is much bigger than 16 bits.  The code should work
+equally well with 16- or 32-bit ints.
+
+In a system where these assumptions are not met, you may be able to make the
+code work by modifying the typedefs in jmorecfg.h.  However, you will probably
+have difficulty if int is less than 16 bits wide, since references to plain
+int abound in the code.
+
+char can be either signed or unsigned, although the code runs faster if an
+unsigned char type is available.  If char is wider than 8 bits, you will need
+to redefine JOCTET and/or provide custom data source/destination managers so
+that JOCTET represents exactly 8 bits of data on external storage.
+
+The JPEG library proper does not assume ASCII representation of characters.
+But some of the image file I/O modules in cjpeg/djpeg do have ASCII
+dependencies in file-header manipulation; so does cjpeg's select_file_type()
+routine.
+
+The JPEG library does not rely heavily on the C library.  In particular, C
+stdio is used only by the data source/destination modules and the error
+handler, all of which are application-replaceable.  (cjpeg/djpeg are more
+heavily dependent on stdio.)  malloc and free are called only from the memory
+manager "back end" module, so you can use a different memory allocator by
+replacing that one file.
+
+The code generally assumes that C names must be unique in the first 15
+characters.  However, global function names can be made unique in the
+first 6 characters by defining NEED_SHORT_EXTERNAL_NAMES.
+
+More info about porting the code may be gleaned by reading jconfig.doc,
+jmorecfg.h, and jinclude.h.
+
+
+Notes for MS-DOS implementors
+-----------------------------
+
+The IJG code is designed to work efficiently in 80x86 "small" or "medium"
+memory models (i.e., data pointers are 16 bits unless explicitly declared
+"far"; code pointers can be either size).  You may be able to use small
+model to compile cjpeg or djpeg by itself, but you will probably have to use
+medium model for any larger application.  This won't make much difference in
+performance.  You *will* take a noticeable performance hit if you use a
+large-data memory model (perhaps 10%-25%), and you should avoid "huge" model
+if at all possible.
+
+The JPEG library typically needs 2Kb-3Kb of stack space.  It will also
+malloc about 20K-30K of near heap space while executing (and lots of far
+heap, but that doesn't count in this calculation).  This figure will vary
+depending on selected operating mode, and to a lesser extent on image size.
+There is also about 5Kb-6Kb of constant data which will be allocated in the
+near data segment (about 4Kb of this is the error message table).
+Thus you have perhaps 20K available for other modules' static data and near
+heap space before you need to go to a larger memory model.  The C library's
+static data will account for several K of this, but that still leaves a good
+deal for your needs.  (If you are tight on space, you could reduce the sizes
+of the I/O buffers allocated by jdatasrc.c and jdatadst.c, say from 4K to
+1K.  Another possibility is to move the error message table to far memory;
+this should be doable with only localized hacking on jerror.c.)
+
+About 2K of the near heap space is "permanent" memory that will not be
+released until you destroy the JPEG object.  This is only an issue if you
+save a JPEG object between compression or decompression operations.
+
+Far data space may also be a tight resource when you are dealing with large
+images.  The most memory-intensive case is decompression with two-pass color
+quantization, or single-pass quantization to an externally supplied color
+map.  This requires a 128Kb color lookup table plus strip buffers amounting
+to about 40 bytes per column for typical sampling ratios (eg, about 25600
+bytes for a 640-pixel-wide image).  You may not be able to process wide
+images if you have large data structures of your own.
+
+Of course, all of these concerns vanish if you use a 32-bit flat-memory-model
+compiler, such as DJGPP or Watcom C.  We highly recommend flat model if you
+can use it; the JPEG library is significantly faster in flat model.

+
+  -all-static       do not do any dynamic linking at all
+  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime
+  -dlpreopen FILE   link in FILE and add its symbols to dld_preloaded_symbols

+  -LLIBDIR          search LIBDIR for required installed libraries
+  -lNAME            OUTPUT-FILE requires the installed library libNAME
+  -no-undefined     declare that a library does not refer to external symbols
+  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
+  -release RELEASE  specify package release information
+  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
+  -static           do not do any dynamic linking of libtool libraries
+  -version-info CURRENT[:REVISION[:AGE]]
+                    specify library version info [each variable defaults to 0]
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename.  Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created, only
+library objects (\`.lo' files) may be specified, and \`-rpath' is required.
+
+If OUTPUT-FILE ends in \`.a', then a standard library is created using \`ar'
+and \`ranlib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.o', then a reloadable object file is
+created, otherwise an executable program is created."

+# Makefile for Independent JPEG Group's software
+
+# This makefile is for Microsoft C for MS-DOS, version 6.00A and up.
+# Use NMAKE, not Microsoft's brain-damaged MAKE.
+# Thanks to Alan Wright and Chris Turner of Olivetti Research Ltd.
+
+# Read installation instructions before saying "nmake" !!
+
+# You may need to adjust these compiler options:
+CFLAGS = -AM -Oecigt -Gs -W3
+# -AM medium memory model (or use -AS for small model, if you remove features)
+# -Oecigt -Gs  maximum safe optimisation (-Ol has bugs in MSC 6.00A)
+# -W3 warning level 3
+# You might also want to add -G2 if you have an 80286, etc.
+# Generally, we recommend defining any configuration symbols in jconfig.h,
+# NOT via -D switches here.
+
+# Jan-Herman Buining suggests the following switches for MS C 8.0 and a 486:
+# CFLAGS = /AM /f- /FPi87 /G3 /Gs /Gy /Ob1 /Oc /Oe /Og /Oi /Ol /On /Oo /Ot \
+#          /OV4 /W3
+# except for jquant1.c, which must be compiled with /Oo- to avoid a compiler
+# crash.
+
+# Ingar Steinsland suggests the following switches when building
+# a 16-bit Windows DLL:
+# CFLAGS = -ALw -Gsw -Zpe -W3 -O2 -Zi -Zd
+
+# Put here the object file name for the correct system-dependent memory
+# manager file.  For DOS, we recommend jmemdos.c and jmemdosa.asm.

+# Makefile for Independent JPEG Group's software
+
+# This makefile is for Microsoft Visual C++ on Windows NT (and 95?).
+# It builds the IJG library as a statically linkable library (.LIB),
+# and builds the sample applications as console-mode apps.
+# Thanks to Xingong Chang, Raymond Everly and others.
+
+# Read installation instructions before saying "nmake" !!
+# To build an optimized library without debug info, say "nmake nodebug=1".
+
+# Pull in standard variable definitions
+!include <win32.mak>
+
+# You may want to adjust these compiler options:
+CFLAGS= $(cflags) $(cdebug) $(cvars) -I.
+# Generally, we recommend defining any configuration symbols in jconfig.h,
+# NOT via -D switches here.
+
+# Link-time options:
+LDFLAGS= $(ldebug) $(conlflags)
+
+# To link any special libraries, add the necessary commands here.
+LDLIBS= $(conlibs)
+
+# Put here the object file name for the correct system-dependent memory
+# manager file.  For NT we suggest jmemnobs.obj, which expects the OS to
+# provide adequate virtual memory.

+-- This AppleScript builds Code Warrior PRO Release 2 project files for the
+-- libjpeg library as well as the test programs 'cjpeg', 'djpeg', 'jpegtran'.
+-- (We'd distribute real project files, except they're not text
+-- and would create maintenance headaches.)
+--
+-- The script then compiles and links the library and the test programs.
+-- NOTE: if you haven't already created a 'jconfig.h' file, the script
+-- automatically copies 'jconfig.mac' to 'jconfig.h'.
+--
+-- To use this script, you must have AppleScript 1.1 or later installed
+-- and a suitable AppleScript editor like Script Editor or Script Debugger
+-- (http://www.latenightsw.com). Open this file with your AppleScript
+-- editor and execute the "run" command to build the projects.
+--
+-- Thanks to Dan Sears and Don Agro for this script.
+-- Questions about this script can be addressed to dogpark@interlog.com

+ * This file is part of the Independent JPEG Group's software.

+ *
+ * This file contains routines to read input images in Microsoft "BMP"
+ * format (MS Windows 3.x, OS/2 1.x, and OS/2 2.x flavors).
+ * Currently, only 8-bit and 24-bit images are supported, not 1-bit or
+ * 4-bit (feeding such low-depth images into JPEG would be silly anyway).
+ * Also, we don't support RLE-compressed files.
+ *
+ * These routines may need modification for non-Unix environments or
+ * specialized applications.  As they stand, they assume input from
+ * an ordinary stdio stream.  They further assume that reading begins
+ * at the start of the file; start_input may need work if the
+ * user interface has already read some data (e.g., to determine that
+ * the file is indeed BMP format).
+ *
+ * This code contributed by James Arthur Boucher.

+.TH RDJPGCOM 1 "11 October 1997"
+.SH NAME
+rdjpgcom \- display text comments from a JPEG file
+.SH SYNOPSIS
+.B rdjpgcom
+[
+.B \-verbose
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B rdjpgcom
+reads the named JPEG/JFIF file, or the standard input if no file is named,
+and prints any text comments found in the file on the standard output.
+.PP
+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.
+Although the standard doesn't actually define what COM blocks are for, they
+are widely used to hold user-supplied text strings.  This lets you add
+annotations, titles, index terms, etc to your JPEG files, and later retrieve
+them as text.  COM blocks do not interfere with the image stored in the JPEG
+file.  The maximum size of a COM block is 64K, but you can have as many of
+them as you like in one JPEG file.
+.SH OPTIONS
+.TP
+.B \-verbose
+Causes
+.B rdjpgcom
+to also display the JPEG image dimensions.
+.PP
+Switch names may be abbreviated, and are not case sensitive.
+.SH HINTS
+.B rdjpgcom
+does not depend on the IJG JPEG library.  Its source code is intended as an
+illustration of the minimum amount of code required to parse a JPEG file
+header correctly.
+.PP
+In
+.B \-verbose
+mode,
+.B rdjpgcom
+will also attempt to print the contents of any "APP12" markers as text.
+Some digital cameras produce APP12 markers containing useful textual
+information.  If you like, you can modify the source code to print
+other APPn marker types as well.

+IJG JPEG LIBRARY:  SYSTEM ARCHITECTURE
+
+Copyright (C) 1991-1995, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+This file provides an overview of the architecture of the IJG JPEG software;
+that is, the functions of the various modules in the system and the interfaces
+between modules.  For more precise details about any data structure or calling
+convention, see the include files and comments in the source code.
+
+We assume that the reader is already somewhat familiar with the JPEG standard.
+The README file includes references for learning about JPEG.  The file
+libjpeg.doc describes the library from the viewpoint of an application
+programmer using the library; it's best to read that file before this one.
+Also, the file coderules.doc describes the coding style conventions we use.
+
+In this document, JPEG-specific terminology follows the JPEG standard:
+  A "component" means a color channel, e.g., Red or Luminance.
+  A "sample" is a single component value (i.e., one number in the image data).
+  A "coefficient" is a frequency coefficient (a DCT transform output number).
+  A "block" is an 8x8 group of samples or coefficients.
+  An "MCU" (minimum coded unit) is an interleaved set of blocks of size
+	determined by the sampling factors, or a single block in a
+	noninterleaved scan.
+We do not use the terms "pixel" and "sample" interchangeably.  When we say
+pixel, we mean an element of the full-size image, while a sample is an element
+of the downsampled image.  Thus the number of samples may vary across
+components while the number of pixels does not.  (This terminology is not used
+rigorously throughout the code, but it is used in places where confusion would
+otherwise result.)
+
+
+*** System features ***
+
+The IJG distribution contains two parts:
+  * A subroutine library for JPEG compression and decompression.
+  * cjpeg/djpeg, two sample applications that use the library to transform
+    JFIF JPEG files to and from several other image formats.
+cjpeg/djpeg are of no great intellectual complexity: they merely add a simple
+command-line user interface and I/O routines for several uncompressed image
+formats.  This document concentrates on the library itself.
+
+We desire the library to be capable of supporting all JPEG baseline, extended
+sequential, and progressive DCT processes.  Hierarchical processes are not
+supported.
+
+The library does not support the lossless (spatial) JPEG process.  Lossless
+JPEG shares little or no code with lossy JPEG, and would normally be used
+without the extensive pre- and post-processing provided by this library.
+We feel that lossless JPEG is better handled by a separate library.
+
+Within these limits, any set of compression parameters allowed by the JPEG
+spec should be readable for decompression.  (We can be more restrictive about
+what formats we can generate.)  Although the system design allows for all
+parameter values, some uncommon settings are not yet implemented and may
+never be; nonintegral sampling ratios are the prime example.  Furthermore,
+we treat 8-bit vs. 12-bit data precision as a compile-time switch, not a
+run-time option, because most machines can store 8-bit pixels much more
+compactly than 12-bit.
+
+For legal reasons, JPEG arithmetic coding is not currently supported, but
+extending the library to include it would be straightforward.
+
+By itself, the library handles only interchange JPEG datastreams --- in
+particular the widely used JFIF file format.  The library can be used by
+surrounding code to process interchange or abbreviated JPEG datastreams that
+are embedded in more complex file formats.  (For example, libtiff uses this
+library to implement JPEG compression within the TIFF file format.)
+
+The library includes a substantial amount of code that is not covered by the
+JPEG standard but is necessary for typical applications of JPEG.  These
+functions preprocess the image before JPEG compression or postprocess it after
+decompression.  They include colorspace conversion, downsampling/upsampling,
+and color quantization.  This code can be omitted if not needed.
+
+A wide range of quality vs. speed tradeoffs are possible in JPEG processing,
+and even more so in decompression postprocessing.  The decompression library
+provides multiple implementations that cover most of the useful tradeoffs,
+ranging from very-high-quality down to fast-preview operation.  On the
+compression side we have generally not provided low-quality choices, since
+compression is normally less time-critical.  It should be understood that the
+low-quality modes may not meet the JPEG standard's accuracy requirements;
+nonetheless, they are useful for viewers.
+
+
+*** Portability issues ***
+
+Portability is an essential requirement for the library.  The key portability
+issues that show up at the level of system architecture are:
+
+1.  Memory usage.  We want the code to be able to run on PC-class machines
+with limited memory.  Images should therefore be processed sequentially (in
+strips), to avoid holding the whole image in memory at once.  Where a
+full-image buffer is necessary, we should be able to use either virtual memory
+or temporary files.
+
+2.  Near/far pointer distinction.  To run efficiently on 80x86 machines, the
+code should distinguish "small" objects (kept in near data space) from
+"large" ones (kept in far data space).  This is an annoying restriction, but
+fortunately it does not impact code quality for less brain-damaged machines,
+and the source code clutter turns out to be minimal with sufficient use of
+pointer typedefs.
+
+3. Data precision.  We assume that "char" is at least 8 bits, "short" and
+"int" at least 16, "long" at least 32.  The code will work fine with larger
+data sizes, although memory may be used inefficiently in some cases.  However,
+the JPEG compressed datastream must ultimately appear on external storage as a
+sequence of 8-bit bytes if it is to conform to the standard.  This may pose a
+problem on machines where char is wider than 8 bits.  The library represents
+compressed data as an array of values of typedef JOCTET.  If no data type
+exactly 8 bits wide is available, custom data source and data destination
+modules must be written to unpack and pack the chosen JOCTET datatype into
+8-bit external representation.
+
+
+*** System overview ***
+
+The compressor and decompressor are each divided into two main sections:
+the JPEG compressor or decompressor proper, and the preprocessing or
+postprocessing functions.  The interface between these two sections is the
+image data that the official JPEG spec regards as its input or output: this
+data is in the colorspace to be used for compression, and it is downsampled
+to the sampling factors to be used.  The preprocessing and postprocessing
+steps are responsible for converting a normal image representation to or from
+this form.  (Those few applications that want to deal with YCbCr downsampled
+data can skip the preprocessing or postprocessing step.)
+
+Looking more closely, the compressor library contains the following main
+elements:
+
+  Preprocessing:
+    * Color space conversion (e.g., RGB to YCbCr).
+    * Edge expansion and downsampling.  Optionally, this step can do simple
+      smoothing --- this is often helpful for low-quality source data.
+  JPEG proper:
+    * MCU assembly, DCT, quantization.
+    * Entropy coding (sequential or progressive, Huffman or arithmetic).
+
+In addition to these modules we need overall control, marker generation,
+and support code (memory management & error handling).  There is also a
+module responsible for physically writing the output data --- typically
+this is just an interface to fwrite(), but some applications may need to
+do something else with the data.
+
+The decompressor library contains the following main elements:
+
+  JPEG proper:
+    * Entropy decoding (sequential or progressive, Huffman or arithmetic).
+    * Dequantization, inverse DCT, MCU disassembly.
+  Postprocessing:
+    * Upsampling.  Optionally, this step may be able to do more general
+      rescaling of the image.
+    * Color space conversion (e.g., YCbCr to RGB).  This step may also
+      provide gamma adjustment [ currently it does not ].
+    * Optional color quantization (e.g., reduction to 256 colors).
+    * Optional color precision reduction (e.g., 24-bit to 15-bit color).
+      [This feature is not currently implemented.]
+
+We also need overall control, marker parsing, and a data source module.
+The support code (memory management & error handling) can be shared with
+the compression half of the library.
+
+There may be several implementations of each of these elements, particularly
+in the decompressor, where a wide range of speed/quality tradeoffs is very
+useful.  It must be understood that some of the best speedups involve
+merging adjacent steps in the pipeline.  For example, upsampling, color space
+conversion, and color quantization might all be done at once when using a
+low-quality ordered-dither technique.  The system architecture is designed to
+allow such merging where appropriate.
+
+
+Note: it is convenient to regard edge expansion (padding to block boundaries)
+as a preprocessing/postprocessing function, even though the JPEG spec includes
+it in compression/decompression.  We do this because downsampling/upsampling
+can be simplified a little if they work on padded data: it's not necessary to
+have special cases at the right and bottom edges.  Therefore the interface
+buffer is always an integral number of blocks wide and high, and we expect
+compression preprocessing to pad the source data properly.  Padding will occur
+only to the next block (8-sample) boundary.  In an interleaved-scan situation,
+additional dummy blocks may be used to fill out MCUs, but the MCU assembly and
+disassembly logic will create or discard these blocks internally.  (This is
+advantageous for speed reasons, since we avoid DCTing the dummy blocks.
+It also permits a small reduction in file size, because the compressor can
+choose dummy block contents so as to minimize their size in compressed form.
+Finally, it makes the interface buffer specification independent of whether
+the file is actually interleaved or not.)  Applications that wish to deal
+directly with the downsampled data must provide similar buffering and padding
+for odd-sized images.
+
+
+*** Poor man's object-oriented programming ***
+
+It should be clear by now that we have a lot of quasi-independent processing
+steps, many of which have several possible behaviors.  To avoid cluttering the
+code with lots of switch statements, we use a simple form of object-style
+programming to separate out the different possibilities.
+
+For example, two different color quantization algorithms could be implemented
+as two separate modules that present the same external interface; at runtime,
+the calling code will access the proper module indirectly through an "object".
+
+We can get the limited features we need while staying within portable C.
+The basic tool is a function pointer.  An "object" is just a struct
+containing one or more function pointer fields, each of which corresponds to
+a method name in real object-oriented languages.  During initialization we
+fill in the function pointers with references to whichever module we have
+determined we need to use in this run.  Then invocation of the module is done
+by indirecting through a function pointer; on most machines this is no more
+expensive than a switch statement, which would be the only other way of
+making the required run-time choice.  The really significant benefit, of
+course, is keeping the source code clean and well structured.
+
+We can also arrange to have private storage that varies between different
+implementations of the same kind of object.  We do this by making all the
+module-specific object structs be separately allocated entities, which will
+be accessed via pointers in the master compression or decompression struct.
+The "public" fields or methods for a given kind of object are specified by
+a commonly known struct.  But a module's initialization code can allocate
+a larger struct that contains the common struct as its first member, plus
+additional private fields.  With appropriate pointer casting, the module's
+internal functions can access these private fields.  (For a simple example,
+see jdatadst.c, which implements the external interface specified by struct
+jpeg_destination_mgr, but adds extra fields.)
+
+(Of course this would all be a lot easier if we were using C++, but we are
+not yet prepared to assume that everyone has a C++ compiler.)
+
+An important benefit of this scheme is that it is easy to provide multiple
+versions of any method, each tuned to a particular case.  While a lot of
+precalculation might be done to select an optimal implementation of a method,
+the cost per invocation is constant.  For example, the upsampling step might
+have a "generic" method, plus one or more "hardwired" methods for the most
+popular sampling factors; the hardwired methods would be faster because they'd
+use straight-line code instead of for-loops.  The cost to determine which
+method to use is paid only once, at startup, and the selection criteria are
+hidden from the callers of the method.
+
+This plan differs a little bit from usual object-oriented structures, in that
+only one instance of each object class will exist during execution.  The
+reason for having the class structure is that on different runs we may create
+different instances (choose to execute different modules).  You can think of
+the term "method" as denoting the common interface presented by a particular
+set of interchangeable functions, and "object" as denoting a group of related
+methods, or the total shared interface behavior of a group of modules.
+
+
+*** Overall control structure ***
+
+We previously mentioned the need for overall control logic in the compression
+and decompression libraries.  In IJG implementations prior to v5, overall
+control was mostly provided by "pipeline control" modules, which proved to be
+large, unwieldy, and hard to understand.  To improve the situation, the
+control logic has been subdivided into multiple modules.  The control modules
+consist of:
+
+1. Master control for module selection and initialization.  This has two
+responsibilities:
+
+   1A.  Startup initialization at the beginning of image processing.
+        The individual processing modules to be used in this run are selected
+        and given initialization calls.
+
+   1B.  Per-pass control.  This determines how many passes will be performed
+        and calls each active processing module to configure itself
+        appropriately at the beginning of each pass.  End-of-pass processing,
+	where necessary, is also invoked from the master control module.
+
+   Method selection is partially distributed, in that a particular processing
+   module may contain several possible implementations of a particular method,
+   which it will select among when given its initialization call.  The master
+   control code need only be concerned with decisions that affect more than
+   one module.
+ 
+2. Data buffering control.  A separate control module exists for each
+   inter-processing-step data buffer.  This module is responsible for
+   invoking the processing steps that write or read that data buffer.
+
+Each buffer controller sees the world as follows:
+
+input data => processing step A => buffer => processing step B => output data
+                      |              |               |
+              ------------------ controller ------------------
+
+The controller knows the dataflow requirements of steps A and B: how much data
+they want to accept in one chunk and how much they output in one chunk.  Its
+function is to manage its buffer and call A and B at the proper times.
+
+A data buffer control module may itself be viewed as a processing step by a
+higher-level control module; thus the control modules form a binary tree with
+elementary processing steps at the leaves of the tree.
+
+The control modules are objects.  A considerable amount of flexibility can
+be had by replacing implementations of a control module.  For example:
+* Merging of adjacent steps in the pipeline is done by replacing a control
+  module and its pair of processing-step modules with a single processing-
+  step module.  (Hence the possible merges are determined by the tree of
+  control modules.)
+* In some processing modes, a given interstep buffer need only be a "strip"
+  buffer large enough to accommodate the desired data chunk sizes.  In other
+  modes, a full-image buffer is needed and several passes are required.
+  The control module determines which kind of buffer is used and manipulates
+  virtual array buffers as needed.  One or both processing steps may be
+  unaware of the multi-pass behavior.
+
+In theory, we might be able to make all of the data buffer controllers
+interchangeable and provide just one set of implementations for all.  In
+practice, each one contains considerable special-case processing for its
+particular job.  The buffer controller concept should be regarded as an
+overall system structuring principle, not as a complete description of the
+task performed by any one controller.
+
+
+*** Compression object structure ***
+
+Here is a sketch of the logical structure of the JPEG compression library:
+
+                                                 |-- Colorspace conversion
+                  |-- Preprocessing controller --|
+                  |                              |-- Downsampling
+Main controller --|
+                  |                            |-- Forward DCT, quantize
+                  |-- Coefficient controller --|
+                                               |-- Entropy encoding
+
+This sketch also describes the flow of control (subroutine calls) during
+typical image data processing.  Each of the components shown in the diagram is
+an "object" which may have several different implementations available.  One
+or more source code files contain the actual implementation(s) of each object.
+
+The objects shown above are:
+
+* Main controller: buffer controller for the subsampled-data buffer, which
+  holds the preprocessed input data.  This controller invokes preprocessing to
+  fill the subsampled-data buffer, and JPEG compression to empty it.  There is
+  usually no need for a full-image buffer here; a strip buffer is adequate.
+
+* Preprocessing controller: buffer controller for the downsampling input data
+  buffer, which lies between colorspace conversion and downsampling.  Note
+  that a unified conversion/downsampling module would probably replace this
+  controller entirely.
+
+* Colorspace conversion: converts application image data into the desired
+  JPEG color space; also changes the data from pixel-interleaved layout to
+  separate component planes.  Processes one pixel row at a time.
+
+* Downsampling: performs reduction of chroma components as required.
+  Optionally may perform pixel-level smoothing as well.  Processes a "row
+  group" at a time, where a row group is defined as Vmax pixel rows of each
+  component before downsampling, and Vk sample rows afterwards (remember Vk
+  differs across components).  Some downsampling or smoothing algorithms may
+  require context rows above and below the current row group; the
+  preprocessing controller is responsible for supplying these rows via proper
+  buffering.  The downsampler is responsible for edge expansion at the right
+  edge (i.e., extending each sample row to a multiple of 8 samples); but the
+  preprocessing controller is responsible for vertical edge expansion (i.e.,
+  duplicating the bottom sample row as needed to make a multiple of 8 rows).
+
+* Coefficient controller: buffer controller for the DCT-coefficient data.
+  This controller handles MCU assembly, including insertion of dummy DCT
+  blocks when needed at the right or bottom edge.  When performing
+  Huffman-code optimization or emitting a multiscan JPEG file, this
+  controller is responsible for buffering the full image.  The equivalent of
+  one fully interleaved MCU row of subsampled data is processed per call,
+  even when the JPEG file is noninterleaved.
+
+* Forward DCT and quantization: Perform DCT, quantize, and emit coefficients.
+  Works on one or more DCT blocks at a time.  (Note: the coefficients are now
+  emitted in normal array order, which the entropy encoder is expected to
+  convert to zigzag order as necessary.  Prior versions of the IJG code did
+  the conversion to zigzag order within the quantization step.)
+
+* Entropy encoding: Perform Huffman or arithmetic entropy coding and emit the
+  coded data to the data destination module.  Works on one MCU per call.
+  For progressive JPEG, the same DCT blocks are fed to the entropy coder
+  during each pass, and the coder must emit the appropriate subset of
+  coefficients.
+
+In addition to the above objects, the compression library includes these
+objects:
+
+* Master control: determines the number of passes required, controls overall
+  and per-pass initialization of the other modules.
+
+* Marker writing: generates JPEG markers (except for RSTn, which is emitted
+  by the entropy encoder when needed).
+
+* Data destination manager: writes the output JPEG datastream to its final
+  destination (e.g., a file).  The destination manager supplied with the
+  library knows how to write to a stdio stream; for other behaviors, the
+  surrounding application may provide its own destination manager.
+
+* Memory manager: allocates and releases memory, controls virtual arrays
+  (with backing store management, where required).
+
+* Error handler: performs formatting and output of error and trace messages;
+  determines handling of nonfatal errors.  The surrounding application may
+  override some or all of this object's methods to change error handling.
+
+* Progress monitor: supports output of "percent-done" progress reports.
+  This object represents an optional callback to the surrounding application:
+  if wanted, it must be supplied by the application.
+
+The error handler, destination manager, and progress monitor objects are
+defined as separate objects in order to simplify application-specific
+customization of the JPEG library.  A surrounding application may override
+individual methods or supply its own all-new implementation of one of these
+objects.  The object interfaces for these objects are therefore treated as
+part of the application interface of the library, whereas the other objects
+are internal to the library.
+
+The error handler and memory manager are shared by JPEG compression and
+decompression; the progress monitor, if used, may be shared as well.
+
+
+*** Decompression object structure ***
+
+Here is a sketch of the logical structure of the JPEG decompression library:
+
+                                               |-- Entropy decoding
+                  |-- Coefficient controller --|
+                  |                            |-- Dequantize, Inverse DCT
+Main controller --|
+                  |                               |-- Upsampling
+                  |-- Postprocessing controller --|   |-- Colorspace conversion
+                                                  |-- Color quantization
+                                                  |-- Color precision reduction
+
+As before, this diagram also represents typical control flow.  The objects
+shown are:
+
+* Main controller: buffer controller for the subsampled-data buffer, which
+  holds the output of JPEG decompression proper.  This controller's primary
+  task is to feed the postprocessing procedure.  Some upsampling algorithms
+  may require context rows above and below the current row group; when this
+  is true, the main controller is responsible for managing its buffer so as
+  to make context rows available.  In the current design, the main buffer is
+  always a strip buffer; a full-image buffer is never required.
+
+* Coefficient controller: buffer controller for the DCT-coefficient data.
+  This controller handles MCU disassembly, including deletion of any dummy
+  DCT blocks at the right or bottom edge.  When reading a multiscan JPEG
+  file, this controller is responsible for buffering the full image.
+  (Buffering DCT coefficients, rather than samples, is necessary to support
+  progressive JPEG.)  The equivalent of one fully interleaved MCU row of
+  subsampled data is processed per call, even when the source JPEG file is
+  noninterleaved.
+
+* Entropy decoding: Read coded data from the data source module and perform
+  Huffman or arithmetic entropy decoding.  Works on one MCU per call.
+  For progressive JPEG decoding, the coefficient controller supplies the prior
+  coefficients of each MCU (initially all zeroes), which the entropy decoder
+  modifies in each scan.
+
+* Dequantization and inverse DCT: like it says.  Note that the coefficients
+  buffered by the coefficient controller have NOT been dequantized; we
+  merge dequantization and inverse DCT into a single step for speed reasons.
+  When scaled-down output is asked for, simplified DCT algorithms may be used
+  that emit only 1x1, 2x2, or 4x4 samples per DCT block, not the full 8x8.
+  Works on one DCT block at a time.
+
+* Postprocessing controller: buffer controller for the color quantization
+  input buffer, when quantization is in use.  (Without quantization, this
+  controller just calls the upsampler.)  For two-pass quantization, this
+  controller is responsible for buffering the full-image data.
+
+* Upsampling: restores chroma components to full size.  (May support more
+  general output rescaling, too.  Note that if undersized DCT outputs have
+  been emitted by the DCT module, this module must adjust so that properly
+  sized outputs are created.)  Works on one row group at a time.  This module
+  also calls the color conversion module, so its top level is effectively a
+  buffer controller for the upsampling->color conversion buffer.  However, in
+  all but the highest-quality operating modes, upsampling and color
+  conversion are likely to be merged into a single step.
+
+* Colorspace conversion: convert from JPEG color space to output color space,
+  and change data layout from separate component planes to pixel-interleaved.
+  Works on one pixel row at a time.
+
+* Color quantization: reduce the data to colormapped form, using either an
+  externally specified colormap or an internally generated one.  This module
+  is not used for full-color output.  Works on one pixel row at a time; may
+  require two passes to generate a color map.  Note that the output will
+  always be a single component representing colormap indexes.  In the current
+  design, the output values are JSAMPLEs, so an 8-bit compilation cannot
+  quantize to more than 256 colors.  This is unlikely to be a problem in
+  practice.
+
+* Color reduction: this module handles color precision reduction, e.g.,
+  generating 15-bit color (5 bits/primary) from JPEG's 24-bit output.
+  Not quite clear yet how this should be handled... should we merge it with
+  colorspace conversion???
+
+Note that some high-speed operating modes might condense the entire
+postprocessing sequence to a single module (upsample, color convert, and
+quantize in one step).
+
+In addition to the above objects, the decompression library includes these
+objects:
+
+* Master control: determines the number of passes required, controls overall
+  and per-pass initialization of the other modules.  This is subdivided into
+  input and output control: jdinput.c controls only input-side processing,
+  while jdmaster.c handles overall initialization and output-side control.
+
+* Marker reading: decodes JPEG markers (except for RSTn).
+
+* Data source manager: supplies the input JPEG datastream.  The source
+  manager supplied with the library knows how to read from a stdio stream;
+  for other behaviors, the surrounding application may provide its own source
+  manager.
+
+* Memory manager: same as for compression library.
+
+* Error handler: same as for compression library.
+
+* Progress monitor: same as for compression library.
+
+As with compression, the data source manager, error handler, and progress
+monitor are candidates for replacement by a surrounding application.
+
+
+*** Decompression input and output separation ***
+
+To support efficient incremental display of progressive JPEG files, the
+decompressor is divided into two sections that can run independently:
+
+1. Data input includes marker parsing, entropy decoding, and input into the
+   coefficient controller's DCT coefficient buffer.  Note that this
+   processing is relatively cheap and fast.
+
+2. Data output reads from the DCT coefficient buffer and performs the IDCT
+   and all postprocessing steps.
+
+For a progressive JPEG file, the data input processing is allowed to get
+arbitrarily far ahead of the data output processing.  (This occurs only
+if the application calls jpeg_consume_input(); otherwise input and output
+run in lockstep, since the input section is called only when the output
+section needs more data.)  In this way the application can avoid making
+extra display passes when data is arriving faster than the display pass
+can run.  Furthermore, it is possible to abort an output pass without
+losing anything, since the coefficient buffer is read-only as far as the
+output section is concerned.  See libjpeg.doc for more detail.
+
+A full-image coefficient array is only created if the JPEG file has multiple
+scans (or if the application specifies buffered-image mode anyway).  When
+reading a single-scan file, the coefficient controller normally creates only
+a one-MCU buffer, so input and output processing must run in lockstep in this
+case.  jpeg_consume_input() is effectively a no-op in this situation.
+
+The main impact of dividing the decompressor in this fashion is that we must
+be very careful with shared variables in the cinfo data structure.  Each
+variable that can change during the course of decompression must be
+classified as belonging to data input or data output, and each section must
+look only at its own variables.  For example, the data output section may not
+depend on any of the variables that describe the current scan in the JPEG
+file, because these may change as the data input section advances into a new
+scan.
+
+The progress monitor is (somewhat arbitrarily) defined to treat input of the
+file as one pass when buffered-image mode is not used, and to ignore data
+input work completely when buffered-image mode is used.  Note that the
+library has no reliable way to predict the number of passes when dealing
+with a progressive JPEG file, nor can it predict the number of output passes
+in buffered-image mode.  So the work estimate is inherently bogus anyway.
+
+No comparable division is currently made in the compression library, because
+there isn't any real need for it.
+
+
+*** Data formats ***
+
+Arrays of pixel sample values use the following data structure:
+
+    typedef something JSAMPLE;		a pixel component value, 0..MAXJSAMPLE
+    typedef JSAMPLE *JSAMPROW;		ptr to a row of samples
+    typedef JSAMPROW *JSAMPARRAY;	ptr to a list of rows
+    typedef JSAMPARRAY *JSAMPIMAGE;	ptr to a list of color-component arrays
+
+The basic element type JSAMPLE will typically be one of unsigned char,
+(signed) char, or short.  Short will be used if samples wider than 8 bits are
+to be supported (this is a compile-time option).  Otherwise, unsigned char is
+used if possible.  If the compiler only supports signed chars, then it is
+necessary to mask off the value when reading.  Thus, all reads of JSAMPLE
+values must be coded as "GETJSAMPLE(value)", where the macro will be defined
+as "((value) & 0xFF)" on signed-char machines and "((int) (value))" elsewhere.
+
+With these conventions, JSAMPLE values can be assumed to be >= 0.  This helps
+simplify correct rounding during downsampling, etc.  The JPEG standard's
+specification that sample values run from -128..127 is accommodated by
+subtracting 128 just as the sample value is copied into the source array for
+the DCT step (this will be an array of signed ints).  Similarly, during
+decompression the output of the IDCT step will be immediately shifted back to
+0..255.  (NB: different values are required when 12-bit samples are in use.
+The code is written in terms of MAXJSAMPLE and CENTERJSAMPLE, which will be
+defined as 255 and 128 respectively in an 8-bit implementation, and as 4095
+and 2048 in a 12-bit implementation.)
+
+We use a pointer per row, rather than a two-dimensional JSAMPLE array.  This
+choice costs only a small amount of memory and has several benefits:
+* Code using the data structure doesn't need to know the allocated width of
+  the rows.  This simplifies edge expansion/compression, since we can work
+  in an array that's wider than the logical picture width.
+* Indexing doesn't require multiplication; this is a performance win on many
+  machines.
+* Arrays with more than 64K total elements can be supported even on machines
+  where malloc() cannot allocate chunks larger than 64K.
+* The rows forming a component array may be allocated at different times
+  without extra copying.  This trick allows some speedups in smoothing steps
+  that need access to the previous and next rows.
+
+Note that each color component is stored in a separate array; we don't use the
+traditional layout in which the components of a pixel are stored together.
+This simplifies coding of modules that work on each component independently,
+because they don't need to know how many components there are.  Furthermore,
+we can read or write each component to a temporary file independently, which
+is helpful when dealing with noninterleaved JPEG files.
+
+In general, a specific sample value is accessed by code such as
+	GETJSAMPLE(image[colorcomponent][row][col])
+where col is measured from the image left edge, but row is measured from the
+first sample row currently in memory.  Either of the first two indexings can
+be precomputed by copying the relevant pointer.
+
+
+Since most image-processing applications prefer to work on images in which
+the components of a pixel are stored together, the data passed to or from the
+surrounding application uses the traditional convention: a single pixel is
+represented by N consecutive JSAMPLE values, and an image row is an array of
+(# of color components)*(image width) JSAMPLEs.  One or more rows of data can
+be represented by a pointer of type JSAMPARRAY in this scheme.  This scheme is
+converted to component-wise storage inside the JPEG library.  (Applications
+that want to skip JPEG preprocessing or postprocessing will have to contend
+with component-wise storage.)
+
+
+Arrays of DCT-coefficient values use the following data structure:
+
+    typedef short JCOEF;		a 16-bit signed integer
+    typedef JCOEF JBLOCK[DCTSIZE2];	an 8x8 block of coefficients
+    typedef JBLOCK *JBLOCKROW;		ptr to one horizontal row of 8x8 blocks
+    typedef JBLOCKROW *JBLOCKARRAY;	ptr to a list of such rows
+    typedef JBLOCKARRAY *JBLOCKIMAGE;	ptr to a list of color component arrays
+
+The underlying type is at least a 16-bit signed integer; while "short" is big
+enough on all machines of interest, on some machines it is preferable to use
+"int" for speed reasons, despite the storage cost.  Coefficients are grouped
+into 8x8 blocks (but we always use #defines DCTSIZE and DCTSIZE2 rather than
+"8" and "64").
+
+The contents of a coefficient block may be in either "natural" or zigzagged
+order, and may be true values or divided by the quantization coefficients,
+depending on where the block is in the processing pipeline.  In the current
+library, coefficient blocks are kept in natural order everywhere; the entropy
+codecs zigzag or dezigzag the data as it is written or read.  The blocks
+contain quantized coefficients everywhere outside the DCT/IDCT subsystems.
+(This latter decision may need to be revisited to support variable
+quantization a la JPEG Part 3.)
+
+Notice that the allocation unit is now a row of 8x8 blocks, corresponding to
+eight rows of samples.  Otherwise the structure is much the same as for
+samples, and for the same reasons.
+
+On machines where malloc() can't handle a request bigger than 64Kb, this data
+structure limits us to rows of less than 512 JBLOCKs, or a picture width of
+4000+ pixels.  This seems an acceptable restriction.
+
+
+On 80x86 machines, the bottom-level pointer types (JSAMPROW and JBLOCKROW)
+must be declared as "far" pointers, but the upper levels can be "near"
+(implying that the pointer lists are allocated in the DS segment).
+We use a #define symbol FAR, which expands to the "far" keyword when
+compiling on 80x86 machines and to nothing elsewhere.
+
+
+*** Suspendable processing ***
+
+In some applications it is desirable to use the JPEG library as an
+incremental, memory-to-memory filter.  In this situation the data source or
+destination may be a limited-size buffer, and we can't rely on being able to
+empty or refill the buffer at arbitrary times.  Instead the application would
+like to have control return from the library at buffer overflow/underrun, and
+then resume compression or decompression at a later time.
+
+This scenario is supported for simple cases.  (For anything more complex, we
+recommend that the application "bite the bullet" and develop real multitasking
+capability.)  The libjpeg.doc file goes into more detail about the usage and
+limitations of this capability; here we address the implications for library
+structure.
+
+The essence of the problem is that the entropy codec (coder or decoder) must
+be prepared to stop at arbitrary times.  In turn, the controllers that call
+the entropy codec must be able to stop before having produced or consumed all
+the data that they normally would handle in one call.  That part is reasonably
+straightforward: we make the controller call interfaces include "progress
+counters" which indicate the number of data chunks successfully processed, and
+we require callers to test the counter rather than just assume all of the data
+was processed.
+
+Rather than trying to restart at an arbitrary point, the current Huffman
+codecs are designed to restart at the beginning of the current MCU after a
+suspension due to buffer overflow/underrun.  At the start of each call, the
+codec's internal state is loaded from permanent storage (in the JPEG object
+structures) into local variables.  On successful completion of the MCU, the
+permanent state is updated.  (This copying is not very expensive, and may even
+lead to *improved* performance if the local variables can be registerized.)
+If a suspension occurs, the codec simply returns without updating the state,
+thus effectively reverting to the start of the MCU.  Note that this implies
+leaving some data unprocessed in the source/destination buffer (ie, the
+compressed partial MCU).  The data source/destination module interfaces are
+specified so as to make this possible.  This also implies that the data buffer
+must be large enough to hold a worst-case compressed MCU; a couple thousand
+bytes should be enough.
+
+In a successive-approximation AC refinement scan, the progressive Huffman
+decoder has to be able to undo assignments of newly nonzero coefficients if it
+suspends before the MCU is complete, since decoding requires distinguishing
+previously-zero and previously-nonzero coefficients.  This is a bit tedious
+but probably won't have much effect on performance.  Other variants of Huffman
+decoding need not worry about this, since they will just store the same values
+again if forced to repeat the MCU.
+
+This approach would probably not work for an arithmetic codec, since its
+modifiable state is quite large and couldn't be copied cheaply.  Instead it
+would have to suspend and resume exactly at the point of the buffer end.
+
+The JPEG marker reader is designed to cope with suspension at an arbitrary
+point.  It does so by backing up to the start of the marker parameter segment,
+so the data buffer must be big enough to hold the largest marker of interest.
+Again, a couple KB should be adequate.  (A special "skip" convention is used
+to bypass COM and APPn markers, so these can be larger than the buffer size
+without causing problems; otherwise a 64K buffer would be needed in the worst
+case.)
+
+The JPEG marker writer currently does *not* cope with suspension.  I feel that
+this is not necessary; it is much easier simply to require the application to
+ensure there is enough buffer space before starting.  (An empty 2K buffer is
+more than sufficient for the header markers; and ensuring there are a dozen or
+two bytes available before calling jpeg_finish_compress() will suffice for the
+trailer.)  This would not work for writing multi-scan JPEG files, but
+we simply do not intend to support that capability with suspension.
+
+
+*** Memory manager services ***
+
+The JPEG library's memory manager controls allocation and deallocation of
+memory, and it manages large "virtual" data arrays on machines where the
+operating system does not provide virtual memory.  Note that the same
+memory manager serves both compression and decompression operations.
+
+In all cases, allocated objects are tied to a particular compression or
+decompression master record, and they will be released when that master
+record is destroyed.
+
+The memory manager does not provide explicit deallocation of objects.
+Instead, objects are created in "pools" of free storage, and a whole pool
+can be freed at once.  This approach helps prevent storage-leak bugs, and
+it speeds up operations whenever malloc/free are slow (as they often are).
+The pools can be regarded as lifetime identifiers for objects.  Two
+pools/lifetimes are defined:
+  * JPOOL_PERMANENT	lasts until master record is destroyed
+  * JPOOL_IMAGE		lasts until done with image (JPEG datastream)
+Permanent lifetime is used for parameters and tables that should be carried
+across from one datastream to another; this includes all application-visible
+parameters.  Image lifetime is used for everything else.  (A third lifetime,
+JPOOL_PASS = one processing pass, was originally planned.  However it was
+dropped as not being worthwhile.  The actual usage patterns are such that the
+peak memory usage would be about the same anyway; and having per-pass storage
+substantially complicates the virtual memory allocation rules --- see below.)
+
+The memory manager deals with three kinds of object:
+1. "Small" objects.  Typically these require no more than 10K-20K total.
+2. "Large" objects.  These may require tens to hundreds of K depending on
+   image size.  Semantically they behave the same as small objects, but we
+   distinguish them for two reasons:
+     * On MS-DOS machines, large objects are referenced by FAR pointers,
+       small objects by NEAR pointers.
+     * Pool allocation heuristics may differ for large and small objects.
+   Note that individual "large" objects cannot exceed the size allowed by
+   type size_t, which may be 64K or less on some machines.
+3. "Virtual" objects.  These are large 2-D arrays of JSAMPLEs or JBLOCKs
+   (typically large enough for the entire image being processed).  The
+   memory manager provides stripwise access to these arrays.  On machines
+   without virtual memory, the rest of the array may be swapped out to a
+   temporary file.
+
+(Note: JSAMPARRAY and JBLOCKARRAY data structures are a combination of large
+objects for the data proper and small objects for the row pointers.  For
+convenience and speed, the memory manager provides single routines to create
+these structures.  Similarly, virtual arrays include a small control block
+and a JSAMPARRAY or JBLOCKARRAY working buffer, all created with one call.)
+
+In the present implementation, virtual arrays are only permitted to have image
+lifespan.  (Permanent lifespan would not be reasonable, and pass lifespan is
+not very useful since a virtual array's raison d'etre is to store data for
+multiple passes through the image.)  We also expect that only "small" objects
+will be given permanent lifespan, though this restriction is not required by
+the memory manager.
+
+In a non-virtual-memory machine, some performance benefit can be gained by
+making the in-memory buffers for virtual arrays be as large as possible.
+(For small images, the buffers might fit entirely in memory, so blind
+swapping would be very wasteful.)  The memory manager will adjust the height
+of the buffers to fit within a prespecified maximum memory usage.  In order
+to do this in a reasonably optimal fashion, the manager needs to allocate all
+of the virtual arrays at once.  Therefore, there isn't a one-step allocation
+routine for virtual arrays; instead, there is a "request" routine that simply
+allocates the control block, and a "realize" routine (called just once) that
+determines space allocation and creates all of the actual buffers.  The
+realize routine must allow for space occupied by non-virtual large objects.
+(We don't bother to factor in the space needed for small objects, on the
+grounds that it isn't worth the trouble.)
+
+To support all this, we establish the following protocol for doing business
+with the memory manager:
+  1. Modules must request virtual arrays (which may have only image lifespan)
+     during the initial setup phase, i.e., in their jinit_xxx routines.
+  2. All "large" objects (including JSAMPARRAYs and JBLOCKARRAYs) must also be
+     allocated during initial setup.
+  3. realize_virt_arrays will be called at the completion of initial setup.
+     The above conventions ensure that sufficient information is available
+     for it to choose a good size for virtual array buffers.
+Small objects of any lifespan may be allocated at any time.  We expect that
+the total space used for small objects will be small enough to be negligible
+in the realize_virt_arrays computation.
+
+In a virtual-memory machine, we simply pretend that the available space is
+infinite, thus causing realize_virt_arrays to decide that it can allocate all
+the virtual arrays as full-size in-memory buffers.  The overhead of the
+virtual-array access protocol is very small when no swapping occurs.
+
+A virtual array can be specified to be "pre-zeroed"; when this flag is set,
+never-yet-written sections of the array are set to zero before being made
+available to the caller.  If this flag is not set, never-written sections
+of the array contain garbage.  (This feature exists primarily because the
+equivalent logic would otherwise be needed in jdcoefct.c for progressive
+JPEG mode; we may as well make it available for possible other uses.)
+
+The first write pass on a virtual array is required to occur in top-to-bottom
+order; read passes, as well as any write passes after the first one, may
+access the array in any order.  This restriction exists partly to simplify
+the virtual array control logic, and partly because some file systems may not
+support seeking beyond the current end-of-file in a temporary file.  The main
+implication of this restriction is that rearrangement of rows (such as
+converting top-to-bottom data order to bottom-to-top) must be handled while
+reading data out of the virtual array, not while putting it in.
+
+
+*** Memory manager internal structure ***
+
+To isolate system dependencies as much as possible, we have broken the
+memory manager into two parts.  There is a reasonably system-independent
+"front end" (jmemmgr.c) and a "back end" that contains only the code
+likely to change across systems.  All of the memory management methods
+outlined above are implemented by the front end.  The back end provides
+the following routines for use by the front end (none of these routines
+are known to the rest of the JPEG code):
+
+jpeg_mem_init, jpeg_mem_term	system-dependent initialization/shutdown
+
+jpeg_get_small, jpeg_free_small	interface to malloc and free library routines
+				(or their equivalents)
+
+jpeg_get_large, jpeg_free_large	interface to FAR malloc/free in MSDOS machines;
+				else usually the same as
+				jpeg_get_small/jpeg_free_small
+
+jpeg_mem_available		estimate available memory
+
+jpeg_open_backing_store		create a backing-store object
+
+read_backing_store,		manipulate a backing-store object
+write_backing_store,
+close_backing_store
+
+On some systems there will be more than one type of backing-store object
+(specifically, in MS-DOS a backing store file might be an area of extended
+memory as well as a disk file).  jpeg_open_backing_store is responsible for
+choosing how to implement a given object.  The read/write/close routines
+are method pointers in the structure that describes a given object; this
+lets them be different for different object types.
+
+It may be necessary to ensure that backing store objects are explicitly
+released upon abnormal program termination.  For example, MS-DOS won't free
+extended memory by itself.  To support this, we will expect the main program
+or surrounding application to arrange to call self_destruct (typically via
+jpeg_destroy) upon abnormal termination.  This may require a SIGINT signal
+handler or equivalent.  We don't want to have the back end module install its
+own signal handler, because that would pre-empt the surrounding application's
+ability to control signal handling.
+
+The IJG distribution includes several memory manager back end implementations.
+Usually the same back end should be suitable for all applications on a given
+system, but it is possible for an application to supply its own back end at
+need.
+
+
+*** Implications of DNL marker ***
+
+Some JPEG files may use a DNL marker to postpone definition of the image
+height (this would be useful for a fax-like scanner's output, for instance).
+In these files the SOF marker claims the image height is 0, and you only
+find out the true image height at the end of the first scan.
+
+We could read these files as follows:
+1. Upon seeing zero image height, replace it by 65535 (the maximum allowed).
+2. When the DNL is found, update the image height in the global image
+   descriptor.
+This implies that control modules must avoid making copies of the image
+height, and must re-test for termination after each MCU row.  This would
+be easy enough to do.
+
+In cases where image-size data structures are allocated, this approach will
+result in very inefficient use of virtual memory or much-larger-than-necessary
+temporary files.  This seems acceptable for something that probably won't be a
+mainstream usage.  People might have to forgo use of memory-hogging options
+(such as two-pass color quantization or noninterleaved JPEG files) if they
+want efficient conversion of such files.  (One could improve efficiency by
+demanding a user-supplied upper bound for the height, less than 65536; in most
+cases it could be much less.)
+
+The standard also permits the SOF marker to overestimate the image height,
+with a DNL to give the true, smaller height at the end of the first scan.
+This would solve the space problems if the overestimate wasn't too great.
+However, it implies that you don't even know whether DNL will be used.
+
+This leads to a couple of very serious objections:
+1. Testing for a DNL marker must occur in the inner loop of the decompressor's
+   Huffman decoder; this implies a speed penalty whether the feature is used
+   or not.
+2. There is no way to hide the last-minute change in image height from an
+   application using the decoder.  Thus *every* application using the IJG
+   library would suffer a complexity penalty whether it cared about DNL or
+   not.
+We currently do not support DNL because of these problems.
+
+A different approach is to insist that DNL-using files be preprocessed by a
+separate program that reads ahead to the DNL, then goes back and fixes the SOF
+marker.  This is a much simpler solution and is probably far more efficient.
+Even if one wants piped input, buffering the first scan of the JPEG file needs
+a lot smaller temp file than is implied by the maximum-height method.  For
+this approach we'd simply treat DNL as a no-op in the decompressor (at most,
+check that it matches the SOF image height).
+
+We will not worry about making the compressor capable of outputting DNL.
+Something similar to the first scheme above could be applied if anyone ever
+wants to make that work.

+ * Lossless image transformation routines.  These routines work on DCT
+ * coefficient arrays and thus do not require any lossy decompression
+ * or recompression of the image.
+ * Thanks to Guido Vollbeding for the initial design and code of this feature.
+ *
+ * Horizontal flipping is done in-place, using a single top-to-bottom
+ * pass through the virtual source array.  It will thus be much the
+ * fastest option for images larger than main memory.
+ *
+ * The other routines require a set of destination virtual arrays, so they
+ * need twice as much memory as jpegtran normally does.  The destination
+ * arrays are always written in normal scan order (top to bottom) because
+ * the virtual array manager expects this.  The source arrays will be scanned
+ * in the corresponding order, which means multiple passes through the source
+ * arrays for most of the transforms.  That could result in much thrashing
+ * if the image is larger than main memory.
+ *
+ * Some notes about the operating environment of the individual transform
+ * routines:
+ * 1. Both the source and destination virtual arrays are allocated from the
+ *    source JPEG object, and therefore should be manipulated by calling the
+ *    source's memory manager.
+ * 2. The destination's component count should be used.  It may be smaller
+ *    than the source's when forcing to grayscale.
+ * 3. Likewise the destination's sampling factors should be used.  When
+ *    forcing to grayscale the destination's sampling factors will be all 1,
+ *    and we may as well take that as the effective iMCU size.
+ * 4. When "trim" is in effect, the destination's dimensions will be the
+ *    trimmed values but the source's will be untrimmed.
+ * 5. All the routines assume that the source and destination buffers are
+ *    padded out to a full iMCU boundary.  This is true, although for the
+ *    source buffer it is an undocumented property of jdcoefct.c.
+ * Notes 2,3,4 boil down to this: generally we should use the destination's
+ * dimensions and ignore the source's.

+USAGE instructions for the Independent JPEG Group's JPEG software
+=================================================================
+
+This file describes usage of the JPEG conversion programs cjpeg and djpeg,
+as well as the utility programs jpegtran, rdjpgcom and wrjpgcom.  (See
+the other documentation files if you wish to use the JPEG library within
+your own programs.)
+
+If you are on a Unix machine you may prefer to read the Unix-style manual
+pages in files cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1.
+
+
+INTRODUCTION
+
+These programs implement JPEG image compression and decompression.  JPEG
+(pronounced "jay-peg") is a standardized compression method for full-color
+and gray-scale images.  JPEG is designed to handle "real-world" scenes,
+for example scanned photographs.  Cartoons, line drawings, and other
+non-realistic images are not JPEG's strong suit; on that sort of material
+you may get poor image quality and/or little compression.
+
+JPEG is lossy, meaning that the output image is not necessarily identical to
+the input image.  Hence you should not use JPEG if you have to have identical
+output bits.  However, on typical real-world images, very good compression
+levels can be obtained with no visible change, and amazingly high compression
+is possible if you can tolerate a low-quality image.  You can trade off image
+quality against file size by adjusting the compressor's "quality" setting.
+
+
+GENERAL USAGE
+
+We provide two programs, cjpeg to compress an image file into JPEG format,
+and djpeg to decompress a JPEG file back into a conventional image format.
+
+On Unix-like systems, you say:
+	cjpeg [switches] [imagefile] >jpegfile
+or
+	djpeg [switches] [jpegfile]  >imagefile
+The programs read the specified input file, or standard input if none is
+named.  They always write to standard output (with trace/error messages to
+standard error).  These conventions are handy for piping images between
+programs.
+
+On most non-Unix systems, you say:
+	cjpeg [switches] imagefile jpegfile
+or
+	djpeg [switches] jpegfile  imagefile
+i.e., both the input and output files are named on the command line.  This
+style is a little more foolproof, and it loses no functionality if you don't
+have pipes.  (You can get this style on Unix too, if you prefer, by defining
+TWO_FILE_COMMANDLINE when you compile the programs; see install.doc.)
+
+You can also say:
+	cjpeg [switches] -outfile jpegfile  imagefile
+or
+	djpeg [switches] -outfile imagefile  jpegfile
+This syntax works on all systems, so it is useful for scripts.
+
+The currently supported image file formats are: PPM (PBMPLUS color format),
+PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster Toolkit
+format).  (RLE is supported only if the URT library is available.)
+cjpeg recognizes the input image format automatically, with the exception
+of some Targa-format files.  You have to tell djpeg which format to generate.
+
+JPEG files are in the defacto standard JFIF file format.  There are other,
+less widely used JPEG-based file formats, but we don't support them.
+
+All switch names may be abbreviated; for example, -grayscale may be written
+-gray or -gr.  Most of the "basic" switches can be abbreviated to as little as
+one letter.  Upper and lower case are equivalent (-BMP is the same as -bmp).
+British spellings are also accepted (e.g., -greyscale), though for brevity
+these are not mentioned below.
+
+
+CJPEG DETAILS
+
+The basic command line switches for cjpeg are:
+
+	-quality N	Scale quantization tables to adjust image quality.
+			Quality is 0 (worst) to 100 (best); default is 75.
+			(See below for more info.)
+
+	-grayscale	Create monochrome JPEG file from color input.
+			Be sure to use this switch when compressing a grayscale
+			BMP file, because cjpeg isn't bright enough to notice
+			whether a BMP file uses only shades of gray.  By
+			saying -grayscale, you'll get a smaller JPEG file that
+			takes less time to process.
+
+	-optimize	Perform optimization of entropy encoding parameters.
+			Without this, default encoding parameters are used.
+			-optimize usually makes the JPEG file a little smaller,
+			but cjpeg runs somewhat slower and needs much more
+			memory.  Image quality and speed of decompression are
+			unaffected by -optimize.
+
+	-progressive	Create progressive JPEG file (see below).
+
+	-targa		Input file is Targa format.  Targa files that contain
+			an "identification" field will not be automatically
+			recognized by cjpeg; for such files you must specify
+			-targa to make cjpeg treat the input as Targa format.
+			For most Targa files, you won't need this switch.
+
+The -quality switch lets you trade off compressed file size against quality of
+the reconstructed image: the higher the quality setting, the larger the JPEG
+file, and the closer the output image will be to the original input.  Normally
+you want to use the lowest quality setting (smallest file) that decompresses
+into something visually indistinguishable from the original image.  For this
+purpose the quality setting should be between 50 and 95; the default of 75 is
+often about right.  If you see defects at -quality 75, then go up 5 or 10
+counts at a time until you are happy with the output image.  (The optimal
+setting will vary from one image to another.)
+
+-quality 100 will generate a quantization table of all 1's, minimizing loss
+in the quantization step (but there is still information loss in subsampling,
+as well as roundoff error).  This setting is mainly of interest for
+experimental purposes.  Quality values above about 95 are NOT recommended for
+normal use; the compressed file size goes up dramatically for hardly any gain
+in output image quality.
+
+In the other direction, quality values below 50 will produce very small files
+of low image quality.  Settings around 5 to 10 might be useful in preparing an
+index of a large image library, for example.  Try -quality 2 (or so) for some
+amusing Cubist effects.  (Note: quality values below about 25 generate 2-byte
+quantization tables, which are considered optional in the JPEG standard.
+cjpeg emits a warning message when you give such a quality value, because some
+other JPEG programs may be unable to decode the resulting file.  Use -baseline
+if you need to ensure compatibility at low quality values.)
+
+The -progressive switch creates a "progressive JPEG" file.  In this type of
+JPEG file, the data is stored in multiple scans of increasing quality.  If the
+file is being transmitted over a slow communications link, the decoder can use
+the first scan to display a low-quality image very quickly, and can then
+improve the display with each subsequent scan.  The final image is exactly
+equivalent to a standard JPEG file of the same quality setting, and the total
+file size is about the same --- often a little smaller.  CAUTION: progressive
+JPEG is not yet widely implemented, so many decoders will be unable to view a
+progressive JPEG file at all.
+
+Switches for advanced users:
+
+	-dct int	Use integer DCT method (default).
+	-dct fast	Use fast integer DCT (less accurate).
+	-dct float	Use floating-point DCT method.
+			The float method is very slightly more accurate than
+			the int method, but is much slower unless your machine
+			has very fast floating-point hardware.  Also note that
+			results of the floating-point method may vary slightly
+			across machines, while the integer methods should give
+			the same results everywhere.  The fast integer method
+			is much less accurate than the other two.
+
+	-restart N	Emit a JPEG restart marker every N MCU rows, or every
+			N MCU blocks if "B" is attached to the number.
+			-restart 0 (the default) means no restart markers.
+
+	-smooth N	Smooth the input image to eliminate dithering noise.
+			N, ranging from 1 to 100, indicates the strength of
+			smoothing.  0 (the default) means no smoothing.
+
+	-maxmemory N	Set limit for amount of memory to use in processing
+			large images.  Value is in thousands of bytes, or
+			millions of bytes if "M" is attached to the number.
+			For example, -max 4m selects 4000000 bytes.  If more
+			space is needed, temporary files will be used.
+
+	-verbose	Enable debug printout.  More -v's give more printout.
+	or  -debug	Also, version information is printed at startup.
+
+The -restart option inserts extra markers that allow a JPEG decoder to
+resynchronize after a transmission error.  Without restart markers, any damage
+to a compressed file will usually ruin the image from the point of the error
+to the end of the image; with restart markers, the damage is usually confined
+to the portion of the image up to the next restart marker.  Of course, the
+restart markers occupy extra space.  We recommend -restart 1 for images that
+will be transmitted across unreliable networks such as Usenet.
+
+The -smooth option filters the input to eliminate fine-scale noise.  This is
+often useful when converting dithered images to JPEG: a moderate smoothing
+factor of 10 to 50 gets rid of dithering patterns in the input file, resulting
+in a smaller JPEG file and a better-looking image.  Too large a smoothing
+factor will visibly blur the image, however.
+
+Switches for wizards:
+
+	-baseline	Force baseline-compatible quantization tables to be
+			generated.  This clamps quantization values to 8 bits
+			even at low quality settings.  (This switch is poorly
+			named, since it does not ensure that the output is
+			actually baseline JPEG.  For example, you can use
+			-baseline and -progressive together.)
+
+	-qtables file	Use the quantization tables given in the specified
+			text file.
+
+	-qslots N[,...] Select which quantization table to use for each color
+			component.
+
+	-sample HxV[,...]  Set JPEG sampling factors for each color component.
+
+	-scans file	Use the scan script given in the specified text file.
+
+The "wizard" switches are intended for experimentation with JPEG.  If you
+don't know what you are doing, DON'T USE THEM.  These switches are documented
+further in the file wizard.doc.
+
+
+DJPEG DETAILS
+
+The basic command line switches for djpeg are:
+
+	-colors N	Reduce image to at most N colors.  This reduces the
+	or -quantize N	number of colors used in the output image, so that it
+			can be displayed on a colormapped display or stored in
+			a colormapped file format.  For example, if you have
+			an 8-bit display, you'd need to reduce to 256 or fewer
+			colors.  (-colors is the recommended name, -quantize
+			is provided only for backwards compatibility.)
+
+	-fast		Select recommended processing options for fast, low
+			quality output.  (The default options are chosen for
+			highest quality output.)  Currently, this is equivalent
+			to "-dct fast -nosmooth -onepass -dither ordered".
+
+	-grayscale	Force gray-scale output even if JPEG file is color.
+			Useful for viewing on monochrome displays; also,
+			djpeg runs noticeably faster in this mode.
+
+	-scale M/N	Scale the output image by a factor M/N.  Currently
+			the scale factor must be 1/1, 1/2, 1/4, or 1/8.
+			Scaling is handy if the image is larger than your
+			screen; also, djpeg runs much faster when scaling
+			down the output.
+
+	-bmp		Select BMP output format (Windows flavor).  8-bit
+			colormapped format is emitted if -colors or -grayscale
+			is specified, or if the JPEG file is gray-scale;
+			otherwise, 24-bit full-color format is emitted.
+
+	-gif		Select GIF output format.  Since GIF does not support
+			more than 256 colors, -colors 256 is assumed (unless
+			you specify a smaller number of colors).  If you
+			specify -fast, the default number of colors is 216.
+
+	-os2		Select BMP output format (OS/2 1.x flavor).  8-bit
+			colormapped format is emitted if -colors or -grayscale
+			is specified, or if the JPEG file is gray-scale;
+			otherwise, 24-bit full-color format is emitted.
+
+	-pnm		Select PBMPLUS (PPM/PGM) output format (this is the
+			default format).  PGM is emitted if the JPEG file is
+			gray-scale or if -grayscale is specified; otherwise
+			PPM is emitted.
+
+	-rle		Select RLE output format.  (Requires URT library.)
+
+	-targa		Select Targa output format.  Gray-scale format is
+			emitted if the JPEG file is gray-scale or if
+			-grayscale is specified; otherwise, colormapped format
+			is emitted if -colors is specified; otherwise, 24-bit
+			full-color format is emitted.
+
+Switches for advanced users:
+
+	-dct int	Use integer DCT method (default).
+	-dct fast	Use fast integer DCT (less accurate).
+	-dct float	Use floating-point DCT method.
+			The float method is very slightly more accurate than
+			the int method, but is much slower unless your machine
+			has very fast floating-point hardware.  Also note that
+			results of the floating-point method may vary slightly
+			across machines, while the integer methods should give
+			the same results everywhere.  The fast integer method
+			is much less accurate than the other two.
+
+	-dither fs	Use Floyd-Steinberg dithering in color quantization.
+	-dither ordered	Use ordered dithering in color quantization.
+	-dither none	Do not use dithering in color quantization.
+			By default, Floyd-Steinberg dithering is applied when
+			quantizing colors; this is slow but usually produces
+			the best results.  Ordered dither is a compromise
+			between speed and quality; no dithering is fast but
+			usually looks awful.  Note that these switches have
+			no effect unless color quantization is being done.
+			Ordered dither is only available in -onepass mode.
+
+	-map FILE	Quantize to the colors used in the specified image
+			file.  This is useful for producing multiple files
+			with identical color maps, or for forcing a predefined
+			set of colors to be used.  The FILE must be a GIF
+			or PPM file.  This option overrides -colors and
+			-onepass.
+
+	-nosmooth	Use a faster, lower-quality upsampling routine.
+
+	-onepass	Use one-pass instead of two-pass color quantization.
+			The one-pass method is faster and needs less memory,
+			but it produces a lower-quality image.  -onepass is
+			ignored unless you also say -colors N.  Also,
+			the one-pass method is always used for gray-scale
+			output (the two-pass method is no improvement then).
+
+	-maxmemory N	Set limit for amount of memory to use in processing
+			large images.  Value is in thousands of bytes, or
+			millions of bytes if "M" is attached to the number.
+			For example, -max 4m selects 4000000 bytes.  If more
+			space is needed, temporary files will be used.
+
+	-verbose	Enable debug printout.  More -v's give more printout.
+	or  -debug	Also, version information is printed at startup.
+
+
+HINTS FOR CJPEG
+
+Color GIF files are not the ideal input for JPEG; JPEG is really intended for
+compressing full-color (24-bit) images.  In particular, don't try to convert
+cartoons, line drawings, and other images that have only a few distinct
+colors.  GIF works great on these, JPEG does not.  If you want to convert a
+GIF to JPEG, you should experiment with cjpeg's -quality and -smooth options
+to get a satisfactory conversion.  -smooth 10 or so is often helpful.
+
+Avoid running an image through a series of JPEG compression/decompression
+cycles.  Image quality loss will accumulate; after ten or so cycles the image
+may be noticeably worse than it was after one cycle.  It's best to use a
+lossless format while manipulating an image, then convert to JPEG format when
+you are ready to file the image away.
+
+The -optimize option to cjpeg is worth using when you are making a "final"
+version for posting or archiving.  It's also a win when you are using low
+quality settings to make very small JPEG files; the percentage improvement
+is often a lot more than it is on larger files.  (At present, -optimize
+mode is always selected when generating progressive JPEG files.)
+
+GIF input files are no longer supported, to avoid the Unisys LZW patent.
+Use a Unisys-licensed program if you need to read a GIF file.  (Conversion
+of GIF files to JPEG is usually a bad idea anyway.)
+
+
+HINTS FOR DJPEG
+
+To get a quick preview of an image, use the -grayscale and/or -scale switches.
+"-grayscale -scale 1/8" is the fastest case.
+
+Several options are available that trade off image quality to gain speed.
+"-fast" turns on the recommended settings.
+
+"-dct fast" and/or "-nosmooth" gain speed at a small sacrifice in quality.
+When producing a color-quantized image, "-onepass -dither ordered" is fast but
+much lower quality than the default behavior.  "-dither none" may give
+acceptable results in two-pass mode, but is seldom tolerable in one-pass mode.
+
+If you are fortunate enough to have very fast floating point hardware,
+"-dct float" may be even faster than "-dct fast".  But on most machines
+"-dct float" is slower than "-dct int"; in this case it is not worth using,
+because its theoretical accuracy advantage is too small to be significant
+in practice.
+
+Two-pass color quantization requires a good deal of memory; on MS-DOS machines
+it may run out of memory even with -maxmemory 0.  In that case you can still
+decompress, with some loss of image quality, by specifying -onepass for
+one-pass quantization.
+
+To avoid the Unisys LZW patent, djpeg produces uncompressed GIF files.  These
+are larger than they should be, but are readable by standard GIF decoders.
+
+
+HINTS FOR BOTH PROGRAMS
+
+If more space is needed than will fit in the available main memory (as
+determined by -maxmemory), temporary files will be used.  (MS-DOS versions
+will try to get extended or expanded memory first.)  The temporary files are
+often rather large: in typical cases they occupy three bytes per pixel, for
+example 3*800*600 = 1.44Mb for an 800x600 image.  If you don't have enough
+free disk space, leave out -progressive and -optimize (for cjpeg) or specify
+-onepass (for djpeg).
+
+On MS-DOS, the temporary files are created in the directory named by the TMP
+or TEMP environment variable, or in the current directory if neither of those
+exist.  Amiga implementations put the temp files in the directory named by
+JPEGTMP:, so be sure to assign JPEGTMP: to a disk partition with adequate free
+space.
+
+The default memory usage limit (-maxmemory) is set when the software is
+compiled.  If you get an "insufficient memory" error, try specifying a smaller
+-maxmemory value, even -maxmemory 0 to use the absolute minimum space.  You
+may want to recompile with a smaller default value if this happens often.
+
+On machines that have "environment" variables, you can define the environment
+variable JPEGMEM to set the default memory limit.  The value is specified as
+described for the -maxmemory switch.  JPEGMEM overrides the default value
+specified when the program was compiled, and itself is overridden by an
+explicit -maxmemory switch.
+
+On MS-DOS machines, -maxmemory is the amount of main (conventional) memory to
+use.  (Extended or expanded memory is also used if available.)  Most
+DOS-specific versions of this software do their own memory space estimation
+and do not need you to specify -maxmemory.
+
+
+JPEGTRAN
+
+jpegtran performs various useful transformations of JPEG files.
+It can translate the coded representation from one variant of JPEG to another,
+for example from baseline JPEG to progressive JPEG or vice versa.  It can also
+perform some rearrangements of the image data, for example turning an image
+from landscape to portrait format by rotation.
+
+jpegtran works by rearranging the compressed data (DCT coefficients), without
+ever fully decoding the image.  Therefore, its transformations are lossless:
+there is no image degradation at all, which would not be true if you used
+djpeg followed by cjpeg to accomplish the same conversion.  But by the same
+token, jpegtran cannot perform lossy operations such as changing the image
+quality.
+
+jpegtran uses a command line syntax similar to cjpeg or djpeg.
+On Unix-like systems, you say:
+	jpegtran [switches] [inputfile] >outputfile
+On most non-Unix systems, you say:
+	jpegtran [switches] inputfile outputfile
+where both the input and output files are JPEG files.
+
+To specify the coded JPEG representation used in the output file,
+jpegtran accepts a subset of the switches recognized by cjpeg:
+	-optimize	Perform optimization of entropy encoding parameters.
+	-progressive	Create progressive JPEG file.
+	-restart N	Emit a JPEG restart marker every N MCU rows, or every
+			N MCU blocks if "B" is attached to the number.
+	-scans file	Use the scan script given in the specified text file.
+See the previous discussion of cjpeg for more details about these switches.
+If you specify none of these switches, you get a plain baseline-JPEG output
+file.  The quality setting and so forth are determined by the input file.
+
+The image can be losslessly transformed by giving one of these switches:
+	-flip horizontal	Mirror image horizontally (left-right).
+	-flip vertical		Mirror image vertically (top-bottom).
+	-rotate 90		Rotate image 90 degrees clockwise.
+	-rotate 180		Rotate image 180 degrees.
+	-rotate 270		Rotate image 270 degrees clockwise (or 90 ccw).
+	-transpose		Transpose image (across UL-to-LR axis).
+	-transverse		Transverse transpose (across UR-to-LL axis).
+
+The transpose transformation has no restrictions regarding image dimensions.
+The other transformations operate rather oddly if the image dimensions are not
+a multiple of the iMCU size (usually 8 or 16 pixels), because they can only
+transform complete blocks of DCT coefficient data in the desired way.
+
+jpegtran's default behavior when transforming an odd-size image is designed
+to preserve exact reversibility and mathematical consistency of the
+transformation set.  As stated, transpose is able to flip the entire image
+area.  Horizontal mirroring leaves any partial iMCU column at the right edge
+untouched, but is able to flip all rows of the image.  Similarly, vertical
+mirroring leaves any partial iMCU row at the bottom edge untouched, but is
+able to flip all columns.  The other transforms can be built up as sequences
+of transpose and flip operations; for consistency, their actions on edge
+pixels are defined to be the same as the end result of the corresponding
+transpose-and-flip sequence.
+
+For practical use, you may prefer to discard any untransformable edge pixels
+rather than having a strange-looking strip along the right and/or bottom edges
+of a transformed image.  To do this, add the -trim switch:
+	-trim		Drop non-transformable edge blocks.
+Obviously, a transformation with -trim is not reversible, so strictly speaking
+jpegtran with this switch is not lossless.  Also, the expected mathematical
+equivalences between the transformations no longer hold.  For example,
+"-rot 270 -trim" trims only the bottom edge, but "-rot 90 -trim" followed by
+"-rot 180 -trim" trims both edges.
+
+Another not-strictly-lossless transformation switch is:
+	-grayscale	Force grayscale output.
+This option discards the chrominance channels if the input image is YCbCr
+(ie, a standard color JPEG), resulting in a grayscale JPEG file.  The
+luminance channel is preserved exactly, so this is a better method of reducing
+to grayscale than decompression, conversion, and recompression.  This switch
+is particularly handy for fixing a monochrome picture that was mistakenly
+encoded as a color JPEG.  (In such a case, the space savings from getting rid
+of the near-empty chroma channels won't be large; but the decoding time for
+a grayscale JPEG is substantially less than that for a color JPEG.)
+
+jpegtran also recognizes these switches that control what to do with "extra"
+markers, such as comment blocks:
+	-copy none	Copy no extra markers from source file.  This setting
+			suppresses all comments and other excess baggage
+			present in the source file.
+	-copy comments	Copy only comment markers.  This setting copies
+			comments from the source file, but discards
+			any other inessential data. 
+	-copy all	Copy all extra markers.  This setting preserves
+			miscellaneous markers found in the source file, such
+			as JFIF thumbnails and Photoshop settings.  In some
+			files these extra markers can be sizable.
+The default behavior is -copy comments.  (Note: in IJG releases v6 and v6a,
+jpegtran always did the equivalent of -copy none.)
+
+Additional switches recognized by jpegtran are:
+	-outfile filename
+	-maxmemory N
+	-verbose
+	-debug
+These work the same as in cjpeg or djpeg.
+
+
+THE COMMENT UTILITIES
+
+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.
+Although the standard doesn't actually define what COM blocks are for, they
+are widely used to hold user-supplied text strings.  This lets you add
+annotations, titles, index terms, etc to your JPEG files, and later retrieve
+them as text.  COM blocks do not interfere with the image stored in the JPEG
+file.  The maximum size of a COM block is 64K, but you can have as many of
+them as you like in one JPEG file.
+
+We provide two utility programs to display COM block contents and add COM
+blocks to a JPEG file.
+
+rdjpgcom searches a JPEG file and prints the contents of any COM blocks on
+standard output.  The command line syntax is
+	rdjpgcom [-verbose] [inputfilename]
+The switch "-verbose" (or just "-v") causes rdjpgcom to also display the JPEG
+image dimensions.  If you omit the input file name from the command line,
+the JPEG file is read from standard input.  (This may not work on some
+operating systems, if binary data can't be read from stdin.)
+
+wrjpgcom adds a COM block, containing text you provide, to a JPEG file.
+Ordinarily, the COM block is added after any existing COM blocks, but you
+can delete the old COM blocks if you wish.  wrjpgcom produces a new JPEG
+file; it does not modify the input file.  DO NOT try to overwrite the input
+file by directing wrjpgcom's output back into it; on most systems this will
+just destroy your file.
+
+The command line syntax for wrjpgcom is similar to cjpeg's.  On Unix-like
+systems, it is
+	wrjpgcom [switches] [inputfilename]
+The output file is written to standard output.  The input file comes from
+the named file, or from standard input if no input file is named.
+
+On most non-Unix systems, the syntax is
+	wrjpgcom [switches] inputfilename outputfilename
+where both input and output file names must be given explicitly.
+
+wrjpgcom understands three switches:
+	-replace		 Delete any existing COM blocks from the file.
+	-comment "Comment text"	 Supply new COM text on command line.
+	-cfile name		 Read text for new COM block from named file.
+(Switch names can be abbreviated.)  If you have only one line of comment text
+to add, you can provide it on the command line with -comment.  The comment
+text must be surrounded with quotes so that it is treated as a single
+argument.  Longer comments can be read from a text file.
+
+If you give neither -comment nor -cfile, then wrjpgcom will read the comment
+text from standard input.  (In this case an input image file name MUST be
+supplied, so that the source JPEG file comes from somewhere else.)  You can
+enter multiple lines, up to 64KB worth.  Type an end-of-file indicator
+(usually control-D or control-Z) to terminate the comment text entry.
+
+wrjpgcom will not add a COM block if the provided comment string is empty.
+Therefore -replace -comment "" can be used to delete all COM blocks from a
+file.
+
+These utility programs do not depend on the IJG JPEG library.  In
+particular, the source code for rdjpgcom is intended as an illustration of
+the minimum amount of code required to parse a JPEG file header correctly.

+Advanced usage instructions for the Independent JPEG Group's JPEG software
+==========================================================================
+
+This file describes cjpeg's "switches for wizards".
+
+The "wizard" switches are intended for experimentation with JPEG by persons
+who are reasonably knowledgeable about the JPEG standard.  If you don't know
+what you are doing, DON'T USE THESE SWITCHES.  You'll likely produce files
+with worse image quality and/or poorer compression than you'd get from the
+default settings.  Furthermore, these switches must be used with caution
+when making files intended for general use, because not all JPEG decoders
+will support unusual JPEG parameter settings.
+
+
+Quantization Table Adjustment
+-----------------------------
+
+Ordinarily, cjpeg starts with a default set of tables (the same ones given
+as examples in the JPEG standard) and scales them up or down according to
+the -quality setting.  The details of the scaling algorithm can be found in
+jcparam.c.  At very low quality settings, some quantization table entries
+can get scaled up to values exceeding 255.  Although 2-byte quantization
+values are supported by the IJG software, this feature is not in baseline
+JPEG and is not supported by all implementations.  If you need to ensure
+wide compatibility of low-quality files, you can constrain the scaled
+quantization values to no more than 255 by giving the -baseline switch.
+Note that use of -baseline will result in poorer quality for the same file
+size, since more bits than necessary are expended on higher AC coefficients.
+
+You can substitute a different set of quantization values by using the
+-qtables switch:
+
+	-qtables file	Use the quantization tables given in the named file.
+
+The specified file should be a text file containing decimal quantization
+values.  The file should contain one to four tables, each of 64 elements.
+The tables are implicitly numbered 0,1,etc. in order of appearance.  Table
+entries appear in normal array order (NOT in the zigzag order in which they
+will be stored in the JPEG file).
+
+Quantization table files are free format, in that arbitrary whitespace can
+appear between numbers.  Also, comments can be included: a comment starts
+with '#' and extends to the end of the line.  Here is an example file that
+duplicates the default quantization tables:
+
+	# Quantization tables given in JPEG spec, section K.1
+
+	# This is table 0 (the luminance table):
+	  16  11  10  16  24  40  51  61
+	  12  12  14  19  26  58  60  55
+	  14  13  16  24  40  57  69  56
+	  14  17  22  29  51  87  80  62
+	  18  22  37  56  68 109 103  77
+	  24  35  55  64  81 104 113  92
+	  49  64  78  87 103 121 120 101
+	  72  92  95  98 112 100 103  99
+
+	# This is table 1 (the chrominance table):
+	  17  18  24  47  99  99  99  99
+	  18  21  26  66  99  99  99  99
+	  24  26  56  99  99  99  99  99

+If the -qtables switch is used without -quality, then the specified tables
+are used exactly as-is.  If both -qtables and -quality are used, then the
+tables taken from the file are scaled in the same fashion that the default
+tables would be scaled for that quality setting.  If -baseline appears, then
+the quantization values are constrained to the range 1-255.
+
+By default, cjpeg will use quantization table 0 for luminance components and
+table 1 for chrominance components.  To override this choice, use the -qslots
+switch:
+
+	-qslots N[,...]		Select which quantization table to use for
+				each color component.
+
+The -qslots switch specifies a quantization table number for each color
+component, in the order in which the components appear in the JPEG SOF marker.
+For example, to create a separate table for each of Y,Cb,Cr, you could
+provide a -qtables file that defines three quantization tables and say
+"-qslots 0,1,2".  If -qslots gives fewer table numbers than there are color
+components, then the last table number is repeated as necessary.
+
+
+Sampling Factor Adjustment
+--------------------------
+
+By default, cjpeg uses 2:1 horizontal and vertical downsampling when
+compressing YCbCr data, and no downsampling for all other color spaces.
+You can override this default with the -sample switch:
+
+	-sample HxV[,...]	Set JPEG sampling factors for each color
+				component.
+
+The -sample switch specifies the JPEG sampling factors for each color
+component, in the order in which they appear in the JPEG SOF marker.
+If you specify fewer HxV pairs than there are components, the remaining
+components are set to 1x1 sampling.  For example, the default YCbCr setting
+is equivalent to "-sample 2x2,1x1,1x1", which can be abbreviated to
+"-sample 2x2".
+
+There are still some JPEG decoders in existence that support only 2x1
+sampling (also called 4:2:2 sampling).  Compatibility with such decoders can
+be achieved by specifying "-sample 2x1".  This is not recommended unless
+really necessary, since it increases file size and encoding/decoding time
+with very little quality gain.
+
+
+Multiple Scan / Progression Control
+-----------------------------------
+
+By default, cjpeg emits a single-scan sequential JPEG file.  The
+-progressive switch generates a progressive JPEG file using a default series
+of progression parameters.  You can create multiple-scan sequential JPEG
+files or progressive JPEG files with custom progression parameters by using
+the -scans switch:
+
+	-scans file	Use the scan sequence given in the named file.
+
+The specified file should be a text file containing a "scan script".
+The script specifies the contents and ordering of the scans to be emitted.
+Each entry in the script defines one scan.  A scan definition specifies
+the components to be included in the scan, and for progressive JPEG it also
+specifies the progression parameters Ss,Se,Ah,Al for the scan.  Scan
+definitions are separated by semicolons (';').  A semicolon after the last
+scan definition is optional.
+
+Each scan definition contains one to four component indexes, optionally
+followed by a colon (':') and the four progressive-JPEG parameters.  The
+component indexes denote which color component(s) are to be transmitted in
+the scan.  Components are numbered in the order in which they appear in the
+JPEG SOF marker, with the first component being numbered 0.  (Note that these
+indexes are not the "component ID" codes assigned to the components, just
+positional indexes.)
+
+The progression parameters for each scan are:
+	Ss	Zigzag index of first coefficient included in scan
+	Se	Zigzag index of last coefficient included in scan
+	Ah	Zero for first scan of a coefficient, else Al of prior scan
+	Al	Successive approximation low bit position for scan
+If the progression parameters are omitted, the values 0,63,0,0 are used,
+producing a sequential JPEG file.  cjpeg automatically determines whether
+the script represents a progressive or sequential file, by observing whether
+Ss and Se values other than 0 and 63 appear.  (The -progressive switch is
+not needed to specify this; in fact, it is ignored when -scans appears.)
+The scan script must meet the JPEG restrictions on progression sequences.
+(cjpeg checks that the spec's requirements are obeyed.)
+
+Scan script files are free format, in that arbitrary whitespace can appear
+between numbers and around punctuation.  Also, comments can be included: a
+comment starts with '#' and extends to the end of the line.  For additional
+legibility, commas or dashes can be placed between values.  (Actually, any
+single punctuation character other than ':' or ';' can be inserted.)  For
+example, the following two scan definitions are equivalent:
+	0 1 2: 0 63 0 0;
+	0,1,2 : 0-63, 0,0 ;
+
+Here is an example of a scan script that generates a partially interleaved
+sequential JPEG file:
+
+	0;			# Y only in first scan
+	1 2;			# Cb and Cr in second scan
+
+Here is an example of a progressive scan script using only spectral selection
+(no successive approximation):
+
+	# Interleaved DC scan for Y,Cb,Cr:
+	0,1,2: 0-0,   0, 0 ;
+	# AC scans:
+	0:     1-2,   0, 0 ;	# First two Y AC coefficients
+	0:     3-5,   0, 0 ;	# Three more
+	1:     1-63,  0, 0 ;	# All AC coefficients for Cb
+	2:     1-63,  0, 0 ;	# All AC coefficients for Cr
+	0:     6-9,   0, 0 ;	# More Y coefficients
+	0:     10-63, 0, 0 ;	# Remaining Y coefficients
+
+Here is an example of a successive-approximation script.  This is equivalent
+to the default script used by "cjpeg -progressive" for YCbCr images:
+
+	# Initial DC scan for Y,Cb,Cr (lowest bit not sent)
+	0,1,2: 0-0,   0, 1 ;
+	# First AC scan: send first 5 Y AC coefficients, minus 2 lowest bits:
+	0:     1-5,   0, 2 ;
+	# Send all Cr,Cb AC coefficients, minus lowest bit:
+	# (chroma data is usually too small to be worth subdividing further;
+	#  but note we send Cr first since eye is least sensitive to Cb)
+	2:     1-63,  0, 1 ;
+	1:     1-63,  0, 1 ;
+	# Send remaining Y AC coefficients, minus 2 lowest bits:
+	0:     6-63,  0, 2 ;
+	# Send next-to-lowest bit of all Y AC coefficients:
+	0:     1-63,  2, 1 ;
+	# At this point we've sent all but the lowest bit of all coefficients.
+	# Send lowest bit of DC coefficients
+	0,1,2: 0-0,   1, 0 ;
+	# Send lowest bit of AC coefficients
+	2:     1-63,  1, 0 ;
+	1:     1-63,  1, 0 ;
+	# Y AC lowest bit scan is last; it's usually the largest scan
+	0:     1-63,  1, 0 ;
+
+It may be worth pointing out that this script is tuned for quality settings
+of around 50 to 75.  For lower quality settings, you'd probably want to use
+a script with fewer stages of successive approximation (otherwise the
+initial scans will be really bad).  For higher quality settings, you might
+want to use more stages of successive approximation (so that the initial
+scans are not too large).

+ *
+ * GIF ordinarily uses variable-width symbols, and the decoder will expect
+ * to ratchet up the symbol width after a fixed number of symbols.
+ * To simplify the logic and keep the expansion penalty down, we emit a
+ * GIF Clear code to reset the decoder just before the width would ratchet up.
+ * Thus, all the symbols in the output file will have the same bit width.
+ * Note that emitting the Clear codes at the right times is a mere matter of
+ * counting output symbols and is in no way dependent on the LZW patent.
+ *
+ * With a small basic pixel width (low color count), Clear codes will be
+ * needed very frequently, causing the file to expand even more.  So this
+ * simplistic approach wouldn't work too well on bilevel images, for example.
+ * But for output of JPEG conversions the pixel width will usually be 8 bits
+ * (129 to 256 colors), so the overhead added by Clear symbols is only about
+ * one symbol in every 256.

+.TH WRJPGCOM 1 "15 June 1995"
+.SH NAME
+wrjpgcom \- insert text comments into a JPEG file
+.SH SYNOPSIS
+.B wrjpgcom
+[
+.B \-replace
+]
+[
+.BI \-comment " text"
+]
+[
+.BI \-cfile " name"
+]
+[
+.I filename
+]
+.LP
+.SH DESCRIPTION
+.LP
+.B wrjpgcom
+reads the named JPEG/JFIF file, or the standard input if no file is named,
+and generates a new JPEG/JFIF file on standard output.  A comment block is
+added to the file.
+.PP
+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.
+Although the standard doesn't actually define what COM blocks are for, they
+are widely used to hold user-supplied text strings.  This lets you add
+annotations, titles, index terms, etc to your JPEG files, and later retrieve
+them as text.  COM blocks do not interfere with the image stored in the JPEG
+file.  The maximum size of a COM block is 64K, but you can have as many of
+them as you like in one JPEG file.
+.PP
+.B wrjpgcom
+adds a COM block, containing text you provide, to a JPEG file.
+Ordinarily, the COM block is added after any existing COM blocks; but you
+can delete the old COM blocks if you wish.
+.SH OPTIONS
+Switch names may be abbreviated, and are not case sensitive.
+.TP
+.B \-replace
+Delete any existing COM blocks from the file.
+.TP
+.BI \-comment " text"
+Supply text for new COM block on command line.
+.TP
+.BI \-cfile " name"
+Read text for new COM block from named file.
+.PP
+If you have only one line of comment text to add, you can provide it on the
+command line with
+.BR \-comment .
+The comment text must be surrounded with quotes so that it is treated as a
+single argument.  Longer comments can be read from a text file.
+.PP
+If you give neither
+.B \-comment
+nor
+.BR \-cfile ,
+then
+.B wrjpgcom
+will read the comment text from standard input.  (In this case an input image
+file name MUST be supplied, so that the source JPEG file comes from somewhere
+else.)  You can enter multiple lines, up to 64KB worth.  Type an end-of-file
+indicator (usually control-D) to terminate the comment text entry.
+.PP
+.B wrjpgcom
+will not add a COM block if the provided comment string is empty.  Therefore
+\fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file.
+.SH EXAMPLES
+.LP
+Add a short comment to in.jpg, producing out.jpg:
+.IP
+.B wrjpgcom \-c
+\fI"View of my back yard" in.jpg
+.B >
+.I out.jpg
+.PP
+Attach a long comment previously stored in comment.txt:
+.IP
+.B wrjpgcom
+.I in.jpg
+.B <
+.I comment.txt
+.B >
+.I out.jpg
+.PP
+or equivalently
+.IP
+.B wrjpgcom
+.B -cfile
+.I comment.txt
+.B <
+.I in.jpg
+.B >
+.I out.jpg

+uzlib - Deflate/Zlib-compatible LZ77 compression/decompression library
+======================================================================
+
+uzlib is a library which can decompress any valid Deflate, Zlib, and Gzip
+(further called just "Deflate") bitstream, and compress data to Deflate-
+compatible bitstream, albeit with lower compression ratio than Zlib Deflate
+algorithm (very basic LZ77 compression algorithm is used instead, static
+Deflate Huffman tree encoding is used for bitstream).
+
+uzlib aims for minimal code size and runtime memory requirements, and thus
+suitable for (deeply) embedded systems.
+
+uzlib is based on:
+
+* tinf library by Joergen Ibsen (Deflate decompression)
+* Deflate Static Huffman tree routines by Simon Tatham
+* LZ77 compressor by Paul Sokolovsky
+
+Library integrated and maintained by Paul Sokolovsky.
+
+(c) 2014-2018 Paul Sokolovsky
+
+uzlib library is licensed under Zlib license.
+
+
+Decompressor features
+---------------------
+
+Handling of input (compressed) stream:
+
+* Can reside (fully) in memory.
+* Can be received, byte by byte, from an application-defined callback
+  function (which e.g. can read it from file or another I/O device).
+* Combination of the above: a chunk of input is buffered in memory,
+  when buffer is exhausted, the application callback is called to refill
+  it.
+
+Handling of output (decompressed) stream:
+
+* In-memory decompression, where output stream fully resides in memory.
+* Streaming decompression, which allows to process arbitrary-sized streams
+  (longer than available memory), but requires in-memory buffer for Deflate
+  dictionary window.
+* Application specifies number of output bytes it wants to decompress,
+  which can be as high as UINT_MAX to decompress everything into memory
+  at once, or as low as 1 to decompress byte by byte, or any other value
+  to decompress a chunk of that size.
+
+Note that in regard to input stream handling, uzlib employs callback-based,
+"pull-style" design. The control flow looks as follows:
+
+1. Application requests uzlib to decompress given number of bytes.
+2. uzlib performs decompression.
+3. If more input is needed to decompress given number of bytes, uzlib
+   calls back into application to provide more input bytes. (An
+   implication of this is that uzlib will always return given number of
+   output bytes, unless end of stream (or error) happens).
+
+The original Zlib library instead features "push-style" design:
+
+1. An application prepares arbitrary number of input bytes in a buffer,
+   and free space in output buffer, and calls Zlib with these buffers.
+2. Zlib tries to decode as much as possible input and produce as much
+   as possible output. It returns back to the application if input
+   buffer is exhausted, or output buffer is full, whatever happens
+   first.
+
+Currently, uzlib doesn't support push-style operation a-la Zlib.
+
+Compressor features
+-------------------
+
+Compressor uses very basic implementation of LZ77 algorithm using hash
+table to find repeating substrings. The size of the hash table (on which
+compression efficiency depends) is currently hardcoded at the compile-time.
+Likewise, the size of LZ77 dictionary is also hardcoded at compile time.
+Both settings should be made runtime-configurable. The hash table is
+allocated on the stack, instead it should be allocated by user and passed
+as an argument to the function (dependency injection pattern).
+
+Currently, compressor doesn't support streaming operation, both input and
+output must reside in memory. Neither it supports incremental operation,
+entire input buffer is compressed at once with a single call to uzlib.
+
+Binary sizes
+------------
+
+To give an impression of code/data sizes of uzlib, the following figures
+are provided. Numbers for *.o files are code sizes of individual
+components (tinflate.o is decompressor, genlz77.o and defl_static.o -
+compressor), and TINF_DATA is the size of the corresponding data
+structure. These numbers are provided for different architectures,
+with default uzlib configuration, and with compilers/their options
+as specified.

+tinf - tiny inflate library
+===========================
+
+Version 1.00
+
+Copyright (c) 2003 Joergen Ibsen
+
+<http://www.ibsensoftware.com/>
+
+
+About
+-----
+
+tinf is a small library implementing the decompression algorithm for the
+deflate compressed data format (called 'inflate'). Deflate compression is
+used in e.g. zlib, gzip, zip and png.
+
+I wrote it because I needed a small in-memory zlib decompressor for a self-
+extracting archive, and the zlib library added 15k to my program. The tinf
+code added only 2k.
+
+Naturally the size difference is insignificant in most cases. Also, the
+zlib library has many more features, is more secure, and mostly faster.
+But if you have a project that calls for a small and simple deflate
+decompressor, give it a try :-)
+
+While the implementation should be fairly compliant, it does assume it is
+given valid compressed data, and that there is sufficient space for the
+decompressed data.
+
+Simple wrappers for decompressing zlib streams and gzip'ed data in memory
+are supplied.
+
+tgunzip, an example command-line gzip decompressor in C, is included.
+
+The inflate algorithm and data format are from 'DEFLATE Compressed Data
+Format Specification version 1.3' ([RFC 1951][1]).
+
+The zlib data format is from 'ZLIB Compressed Data Format Specification
+version 3.3' ([RFC 1950][2]).
+
+The gzip data format is from 'GZIP file format specification version 4.3'
+([RFC 1952][3]).
+
+Ideas for future versions:
+
+- the fixed Huffman trees could be built by `tinf_decode_trees()`
+  using a small table
+- memory for the `TINF_DATA` object should be passed, to avoid using
+  more than 1k of stack space
+- wrappers for unpacking zip archives and png images
+- implement more in x86 assembler
+- more sanity checks
+- in `tinf_uncompress`, the (entry value of) `destLen` and `sourceLen`
+  are not used
+- blocking of some sort, so everything does not have to be in memory
+- optional table-based huffman decoder

+
+Functionality
+-------------
+
+    void tinf_init();
+
+Initialise the global uninitialised data used by the decompression code.
+This function must be called once before any calls to the decompression
+functions.
+
+    int tinf_uncompress(void *dest,
+                        unsigned int *destLen,
+                        const void *source,
+                        unsigned int sourceLen);
+
+Decompress data in deflate compressed format from `source[]` to `dest[]`.
+`destLen` is set to the length of the decompressed data. Returns `TINF_OK`
+on success, and `TINF_DATA_ERROR` on error.
+
+    int tinf_gzip_uncompress(void *dest,
+                             unsigned int *destLen,
+                             const void *source,
+                             unsigned int sourceLen);
+
+Decompress data in gzip compressed format from `source[]` to `dest[]`.
+`destLen` is set to the length of the decompressed data. Returns `TINF_OK`
+on success, and `TINF_DATA_ERROR` on error.
+
+    int tinf_zlib_uncompress(void *dest,
+                             unsigned int *destLen,
+                             const void *source,
+                             unsigned int sourceLen);
+
+Decompress data in zlib compressed format from `source[]` to `dest[]`.
+`destLen` is set to the length of the decompressed data. Returns `TINF_OK`
+on success, and `TINF_DATA_ERROR` on error.
+
+    unsigned int tinf_adler32(const void *data,
+                              unsigned int length);
+
+Computes the Adler-32 checksum of `length` bytes starting at `data`. Used by
+`tinf_zlib_uncompress()`.
+
+    unsigned int tinf_crc32(const void *data,
+                            unsigned int length);
+
+Computes the CRC32 checksum of `length` bytes starting at `data`. Used by
+`tinf_gzip_uncompress()`.
+
+
+Source Code
+-----------
+
+The source code is ANSI C, and assumes that int is 32-bit. It has been
+tested on the x86 platform under Windows and Linux.
+
+The decompression functions should be endian-neutral, and also reentrant
+and thread-safe (not tested).
+
+In src/nasm there are 32-bit x86 assembler (386+) versions of some of the
+files.
+
+Makefiles (GNU Make style) for a number of compilers are included.
+
+
+Frequently Asked Questions
+--------------------------
+
+Q: Is it really free? Can I use it in my commercial ExpenZip software?
+
+A: It's open-source software, available under the zlib license (see
+   later), which means you can use it for free -- even in commercial
+   products. If you do, please be kind enough to add an acknowledgement.
+
+Q: Did you just strip stuff from the zlib source to make it smaller?
+
+A: No, tinf was written from scratch, using the RFC documentation of
+   the formats it supports.
+
+Q: What do you mean by: 'the zlib library .. is more secure'?
+
+A: The zlib decompression code checks the compressed data for validity
+   while decompressing, so even on corrupted data it will not crash.
+   The tinf code assumes it is given valid compressed data.
+
+Q: I'm a Delphi programmer, can I use tinf?
+
+A: Sure, the object files produced by both Borland C and Watcom C should
+   be linkable with Delphi.
+
+Q: Will tinf work on UltraSTRANGE machines running WhackOS?
+
+A: I have no idea .. please try it out and let me know!
+
+Q: Why are all the makefiles in GNU Make style?
+
+A: I'm used to GNU Make, and it has a number of features that are missing
+   in some of the other Make utilities.
+
+Q: This is the first release, how can there be frequently asked questions?
+
+A: Ok, ok .. I made the questions up ;-)

+
+; define _ELF_ for ELF32 object files
+; define _OBJ_ for OMF object files
+; define _OBJ_ and _DLL_ for OMF object files for a dll (stdcall)
+; define _MSLIBS_ for MS style Win32 import libs (lcmwinextern)
+; default is DJGPP/WIN32 COFF object files
+
+; remember to do lcm*extern before lcmimport
+
+; ====================================================================
+;
+; There are differences between how the object formats that NASM
+; supports work, and what features they support. Similarly there
+; are differences between how complete and standard compliant the
+; support for these formats are in linkers.
+;
+; The NASM linker compatibility macros (nasmlcm) were put together
+; to ease my work by allowing a single source file to be assembled
+; for use with a number of compilers/linkers.
+;
+; Currently obj/omf, win32/coff, djgpp/coff and elf32 output formats
+; are supported. The following macros are available:
+;
+;   lcmtext       - section name for the code section
+;   lcmdata       - section name for the initialized data section
+;   lcmbss        - section name for the uninitialized data section
+;
+;   lcmglobal     - declare a function (two arguments) or data (one
+;                   argument) as global in the current format
+;   lcmcglobal    - same as lcmglobal, but uses C name decoration
+;
+;   lcmextern     - declare a function (two arguments) or data (one
+;                   argument) as extern in the current format
+;   lcmcextern    - same as lcmextern, but uses C name decoration
+;   lcmdllextern  - same as lcmextern, but uses dll name decoration
+;   lcmwinextern  - same as lcmextern, but uses name decoration for
+;                   calling Win32 Api functions (see _MSLIBS_)
+;
+;   lcmimport     - declares a function (two arguments) or data (one
+;                   argument) as imported in the current format
+;   lcmexport     - declares a function (two arguments) or data (one
+;                   argument) as exported in the current format
+;
+;   lcmlabel      - start label for a function in the current format
+;   lcmclabel     - start label for a function with C name decoration
+;   lcmadjust     - adjust stack after a function call in the current
+;                   format
+;   lcmret        - return from a function in the current format
+;   lcmcret       - return from a C function
+;
+; The following defines change the format and behaviour:
+;
+;   _ELF_     -  the lcm*global macro adds :function and :data type
+;                specifiers
+;
+;   _OBJ_     -  section names are similar to those produced by
+;                Borland tools to increase compatibility with
+;                various OMF compatible linkers
+;
+;   _DLL_     -  functions are exported and imported with added
+;                size specifiers (_SomeFunction@12), lcmret adjusts
+;                stack (stdcall)
+;
+;   _MSLIBS_  -  the lcmwinextern macro prepends an underscore and
+;                adds size specification for functions, allowing
+;                the object file to be linked with MS libraries.

+Bitsliced AES
+-------------
+
+Bitslicing is a technique to compute steps in an algorithm 1 bit at a time.  Each bit in a processor word would be a part
+of a different data stream for that particular algorithm.  It is attractive because then it can run many different streams 
+in parallel (depending on the word length).  E.g. a 32 bit word length can compute 32 different streams in parallel.
+
+Some encryption algorithms allow blocks to be operated on in parallel like AES CTR.  So if there is enough input, say 32 blocks,
+then a 32 bit processor can achieve full utilitization by filling all bits in word and enciphering all blocks in parallel.
+
+
+Research
+--------
+
+
+Bitslicing is not a new idea.  It was first done on DES by Eli Biham in 1997 as described by his paper "A Fast New DES Implementation in Software".
+Since then many implementations have been done on AES and other encryption algorithms.  However none are either pubicly available or easily portable.
+
+
+This bitsliced implementation
+-----------------------------
+
+This work exists for education and research.  This repository exists as a reference for people working on bitslicing.
+It is written entirely in C.
+
+Performance measurements done for AES-CTR on a 64 bit 4 GHz Intel 4790 and compiled with GCC 4.8.4.
+
+|                      |footprint | throughput |
+|----------------------|----------|------------|
+|Performance optimized |  12,150 bytes  | 51 cycles/byte |
+|Footprint optimized   | 8,526 bytes | 81 cycles/byte |
+
+Performance could be improved by about 5-10x by writting in assembly and ensuring
+more operations stay in registers rather then spill to memory.
+
+
+Compiling
+----------
+
+Compile the benchmarking program by running:
+
+```bash
+make
+```
+
+Benchmark program requires OpenSSL.
+
+
+Compile the test program by running:
+
+```bash
+make test
+```
+
+Change to the word length of your processor by editing the `WORD_SIZE` macro in bs.h.  Optimize for
+footprint by using `-O2` instead of `-O3` in the Makefile and also deleting the `-DUNROLL_TRANSPOSE` 
+flag.

-CHANGE LOG for Independent JPEG Group's JPEG software
-
-
-Version 6b  27-Mar-1998
------------------------
-
-jpegtran has new features for lossless image transformations (rotation
-and flipping) as well as "lossless" reduction to grayscale.
-
-jpegtran now copies comments by default; it has a -copy switch to enable
-copying all APPn blocks as well, or to suppress comments.  (Formerly it
-always suppressed comments and APPn blocks.)  jpegtran now also preserves
-JFIF version and resolution information.
-
-New decompressor library feature: COM and APPn markers found in the input
-file can be saved in memory for later use by the application.  (Before,
-you had to code this up yourself with a custom marker processor.)
-
-There is an unused field "void * client_data" now in compress and decompress
-parameter structs; this may be useful in some applications.
-
-JFIF version number information is now saved by the decoder and accepted by
-the encoder.  jpegtran uses this to copy the source file's version number,
-to ensure "jpegtran -copy all" won't create bogus files that contain JFXX
-extensions but claim to be version 1.01.  Applications that generate their
-own JFXX extension markers also (finally) have a supported way to cause the
-encoder to emit JFIF version number 1.02.
-
-djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather
-than as unknown APP0 markers.
-
-In -verbose mode, djpeg and rdjpgcom will try to print the contents of
-APP12 markers as text.  Some digital cameras store useful text information
-in APP12 markers.
-
-Handling of truncated data streams is more robust: blocks beyond the one in
-which the error occurs will be output as uniform gray, or left unchanged
-if decoding a progressive JPEG.  The appearance no longer depends on the
-Huffman tables being used.
-
-Huffman tables are checked for validity much more carefully than before.
-
-To avoid the Unisys LZW patent, djpeg's GIF output capability has been
-changed to produce "uncompressed GIFs", and cjpeg's GIF input capability
-has been removed altogether.  We're not happy about it either, but there
-seems to be no good alternative.
-
-The configure script now supports building libjpeg as a shared library
-on many flavors of Unix (all the ones that GNU libtool knows how to
-build shared libraries for).  Use "./configure --enable-shared" to
-try this out.
-
-New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio.
-Also, a jconfig file and a build script for Metrowerks CodeWarrior
-on Apple Macintosh.  makefile.dj has been updated for DJGPP v2, and there
-are miscellaneous other minor improvements in the makefiles.
-
-jmemmac.c now knows how to create temporary files following Mac System 7
-conventions.
-
-djpeg's -map switch is now able to read raw-format PPM files reliably.
-
-cjpeg -progressive -restart no longer generates any unnecessary DRI markers.
-
-Multiple calls to jpeg_simple_progression for a single JPEG object
-no longer leak memory.
-
-
-Version 6a  7-Feb-96
---------------------
-
-Library initialization sequence modified to detect version mismatches
-and struct field packing mismatches between library and calling application.
-This change requires applications to be recompiled, but does not require
-any application source code change.
-
-All routine declarations changed to the style "GLOBAL(type) name ...",
-that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the
-routine's return type as an argument.  This makes it possible to add
-Microsoft-style linkage keywords to all the routines by changing just
-these macros.  Note that any application code that was using these macros
-will have to be changed.
-
-DCT coefficient quantization tables are now stored in normal array order
-rather than zigzag order.  Application code that calls jpeg_add_quant_table,
-or otherwise manipulates quantization tables directly, will need to be
-changed.  If you need to make such code work with either older or newer
-versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is
-recommended.
-
-djpeg's trace capability now dumps DQT tables in natural order, not zigzag
-order.  This allows the trace output to be made into a "-qtables" file
-more easily.
-
-New system-dependent memory manager module for use on Apple Macintosh.
-
-Fix bug in cjpeg's -smooth option: last one or two scanlines would be
-duplicates of the prior line unless the image height mod 16 was 1 or 2.
-
-Repair minor problems in VMS, BCC, MC6 makefiles.
-
-New configure script based on latest GNU Autoconf.
-
-Correct the list of include files needed by MetroWerks C for ccommand().
-
-Numerous small documentation updates.
-
-
-Version 6  2-Aug-95
--------------------
-
-Progressive JPEG support: library can read and write full progressive JPEG
-files.  A "buffered image" mode supports incremental decoding for on-the-fly
-display of progressive images.  Simply recompiling an existing IJG-v5-based
-decoder with v6 should allow it to read progressive files, though of course
-without any special progressive display.
-
-New "jpegtran" application performs lossless transcoding between different
-JPEG formats; primarily, it can be used to convert baseline to progressive
-JPEG and vice versa.  In support of jpegtran, the library now allows lossless
-reading and writing of JPEG files as DCT coefficient arrays.  This ability
-may be of use in other applications.
-
-Notes for programmers:
-* We changed jpeg_start_decompress() to be able to suspend; this makes all
-decoding modes available to suspending-input applications.  However,
-existing applications that use suspending input will need to be changed
-to check the return value from jpeg_start_decompress().  You don't need to
-do anything if you don't use a suspending data source.
-* We changed the interface to the virtual array routines: access_virt_array
-routines now take a count of the number of rows to access this time.  The
-last parameter to request_virt_array routines is now interpreted as the
-maximum number of rows that may be accessed at once, but not necessarily
-the height of every access.
-
-
-Version 5b  15-Mar-95
----------------------
-
-Correct bugs with grayscale images having v_samp_factor > 1.
-
-jpeg_write_raw_data() now supports output suspension.
-
-Correct bugs in "configure" script for case of compiling in
-a directory other than the one containing the source files.
-
-Repair bug in jquant1.c: sometimes didn't use as many colors as it could.
-
-Borland C makefile and jconfig file work under either MS-DOS or OS/2.
-
-Miscellaneous improvements to documentation.
-
-
-Version 5a  7-Dec-94
---------------------
-
-Changed color conversion roundoff behavior so that grayscale values are
-represented exactly.  (This causes test image files to change.)
-
-Make ordered dither use 16x16 instead of 4x4 pattern for a small quality
-improvement.
-
-New configure script based on latest GNU Autoconf.
-Fix configure script to handle CFLAGS correctly.
-Rename *.auto files to *.cfg, so that configure script still works if
-file names have been truncated for DOS.
-
-Fix bug in rdbmp.c: didn't allow for extra data between header and image.
-
-Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data.
-
-Fix several bugs in rdrle.c.
-
-NEED_SHORT_EXTERNAL_NAMES option was broken.
-
-Revise jerror.h/jerror.c for more flexibility in message table.
-
-Repair oversight in jmemname.c NO_MKTEMP case: file could be there
-but unreadable.
-
-
-Version 5  24-Sep-94
---------------------
-
-Version 5 represents a nearly complete redesign and rewrite of the IJG
-software.  Major user-visible changes include:
-  * Automatic configuration simplifies installation for most Unix systems.
-  * A range of speed vs. image quality tradeoffs are supported.
-    This includes resizing of an image during decompression: scaling down
-    by a factor of 1/2, 1/4, or 1/8 is handled very efficiently.
-  * New programs rdjpgcom and wrjpgcom allow insertion and extraction
-    of text comments in a JPEG file.
-
-The application programmer's interface to the library has changed completely.
-Notable improvements include:
-  * We have eliminated the use of callback routines for handling the
-    uncompressed image data.  The application now sees the library as a
-    set of routines that it calls to read or write image data on a
-    scanline-by-scanline basis.
-  * The application image data is represented in a conventional interleaved-
-    pixel format, rather than as a separate array for each color channel.
-    This can save a copying step in many programs.
-  * The handling of compressed data has been cleaned up: the application can
-    supply routines to source or sink the compressed data.  It is possible to
-    suspend processing on source/sink buffer overrun, although this is not
-    supported in all operating modes.
-  * All static state has been eliminated from the library, so that multiple
-    instances of compression or decompression can be active concurrently.
-  * JPEG abbreviated datastream formats are supported, ie, quantization and
-    Huffman tables can be stored separately from the image data.
-  * And not only that, but the documentation of the library has improved
-    considerably!
-
-
-The last widely used release before the version 5 rewrite was version 4A of
-18-Feb-93.  Change logs before that point have been discarded, since they
-are not of much interest after the rewrite.

+   1. Non-recursive, using an explicit stack of pointer that store the

+      of space required to store an array of SIZE_MAX is allocated on the
+      stack.  Assuming a 32-bit (64 bit) integer for size_t, this needs
+      only 32 * sizeof(stack_node) == 256 bytes (for 64 bit: 1024 bytes).
+      Pretty cheap, actually.
+   2. Chose the pivot element using a median-of-three decision tree.
+      This reduces the probability of selecting a bad pivot value and
+      eliminates certain extraneous comparisons.
+   3. Only quicksorts TOTAL_ELEMS / MAX_THRESH partitions, leaving
+      insertion sort to order the MAX_THRESH items within each partition.
+      This is a big win, since insertion sort is faster for small, mostly
+      sorted array segments.
+   4. The larger of the two sub-partitions is always pushed onto the
+      stack first, with the algorithm then concentrating on the
+      smaller partition.  This *guarantees* no more than log (total_elems)
+      stack size is needed (actually O(1) in this case)!  */

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

-		    GHOSTSCRIPT GENERAL PUBLIC LICENSE
-		    (Clarified 11 Feb 1988)
-
- Copyright (C) 1988 Richard M. Stallman
- Everyone is permitted to copy and distribute verbatim copies of this
- license, but changing it is not allowed.  You can also use this wording
- to make the terms for other programs.
-
-  The license agreements of most software companies keep you at the
-mercy of those companies.  By contrast, our general public license is
-intended to give everyone the right to share Ghostscript.  To make sure
-that you get the rights we want you to have, we need to make
-restrictions that forbid anyone to deny you these rights or to ask you
-to surrender the rights.  Hence this license agreement.
-
-  Specifically, we want to make sure that you have the right to give
-away copies of Ghostscript, that you receive source code or else can get
-it if you want it, that you can change Ghostscript or use pieces of it
-in new free programs, and that you know you can do these things.
-
-  To make sure that everyone has such rights, we have to forbid you to
-deprive anyone else of these rights.  For example, if you distribute
-copies of Ghostscript, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must tell them their rights.
-
-  Also, for our own protection, we must make certain that everyone finds
-out that there is no warranty for Ghostscript.  If Ghostscript is
-modified by someone else and passed on, we want its recipients to know
-that what they have is not what we distributed, so that any problems
-introduced by others will not reflect on our reputation.
-
-  Therefore we (Richard M. Stallman and the Free Software Foundation,
-Inc.) make the following terms which say what you must do to be allowed
-to distribute or change Ghostscript.
-
-
-			COPYING POLICIES
-
-  1. You may copy and distribute verbatim copies of Ghostscript source
-code as you receive it, in any medium, provided that you conspicuously
-and appropriately publish on each copy a valid copyright and license
-notice "Copyright (C) 1989 Aladdin Enterprises.  All rights reserved.
-Distributed by Free Software Foundation, Inc." (or with whatever year is
-appropriate); keep intact the notices on all files that refer to this
-License Agreement and to the absence of any warranty; and give any other
-recipients of the Ghostscript program a copy of this License Agreement
-along with the program.  You may charge a distribution fee for the
-physical act of transferring a copy.
-
-  2. You may modify your copy or copies of Ghostscript or any portion of
-it, and copy and distribute such modifications under the terms of
-Paragraph 1 above, provided that you also do the following:
-
-    a) cause the modified files to carry prominent notices stating
-    that you changed the files and the date of any change; and
-
-    b) cause the whole of any work that you distribute or publish,
-    that in whole or in part contains or is a derivative of Ghostscript
-    or any part thereof, to be licensed at no charge to all third
-    parties on terms identical to those contained in this License
-    Agreement (except that you may choose to grant more extensive
-    warranty protection to some or all third parties, at your option).
-
-    c) You may charge a distribution fee for the physical act of
-    transferring a copy, and you may at your option offer warranty
-    protection in exchange for a fee.
-
-Mere aggregation of another unrelated program with this program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other program under the scope of these terms.
-
-  3. You may copy and distribute Ghostscript (or a portion or derivative
-of it, under Paragraph 2) in object code or executable form under the
-terms of Paragraphs 1 and 2 above provided that you also do one of the
-following:
-
-    a) accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    b) accompany it with a written offer, valid for at least three
-    years, to give any third party free (except for a nominal
-    shipping charge) a complete machine-readable copy of the
-    corresponding source code, to be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    c) accompany it with the information you received as to where the
-    corresponding source code may be obtained.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form alone.)
-
-For an executable file, complete source code means all the source code for
-all modules it contains; but, as a special exception, it need not include
-source code for modules which are standard libraries that accompany the
-operating system on which the executable file runs.
-
-  4. You may not copy, sublicense, distribute or transfer Ghostscript
-except as expressly provided under this License Agreement.  Any attempt
-otherwise to copy, sublicense, distribute or transfer Ghostscript is
-void and your rights to use the program under this License agreement
-shall be automatically terminated.  However, parties who have received
-computer software programs from you with this License Agreement will not
-have their licenses terminated so long as such parties remain in full
-compliance.
-
-  5. If you wish to incorporate parts of Ghostscript into other free
-programs whose distribution conditions are different, write to the Free
-Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not
-yet worked out a simple rule that can be stated here, but we will often
-permit this.  We will be guided by the two goals of preserving the free
-status of all derivatives of our free software and of promoting the
-sharing and reuse of software.
-
-Your comments and suggestions about our licensing policies and our
-software are welcome!  Please contact the Free Software Foundation,
-Inc., 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.

-  BECAUSE GHOSTSCRIPT IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY
-NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW.  EXCEPT
-WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, RICHARD

-PROVIDE GHOSTSCRIPT "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
-EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED

-/*
- * Usage:
-	ansi2knr input_file [output_file]
- * If no output_file is supplied, output goes to stdout.
- * There are no error messages.
- *
- * ansi2knr recognizes function definitions by seeing a non-keyword
- * identifier at the left margin, followed by a left parenthesis,
- * with a right parenthesis as the last character on the line,
- * and with a left brace as the first token on the following line
- * (ignoring possible intervening comments).
- * It will recognize a multi-line header provided that no intervening
- * line ends with a left or right brace or a semicolon.
- * These algorithms ignore whitespace and comments, except that
- * the function name must be the first thing on the line.
- * The following constructs will confuse it:
- *	- Any other construct that starts at the left margin and
- *	    follows the above syntax (such as a macro or function call).
- *	- Some macros that tinker with the syntax of the function header.
- */

-/*
- * The original and principal author of ansi2knr is L. Peter Deutsch
- * <ghost@aladdin.com>.  Other authors are noted in the change history
- * that follows (in reverse chronological order):
-	lpd 96-01-21 added code to cope with not HAVE_CONFIG_H and with
-		compilers that don't understand void, as suggested by
-		Tom Lane
-	lpd 96-01-15 changed to require that the first non-comment token
-		on the line following a function header be a left brace,
-		to reduce sensitivity to macros, as suggested by Tom Lane
-		<tgl@sss.pgh.pa.us>
-	lpd 95-06-22 removed #ifndefs whose sole purpose was to define
-		undefined preprocessor symbols as 0; changed all #ifdefs
-		for configuration symbols to #ifs
-	lpd 95-04-05 changed copyright notice to make it clear that
-		including ansi2knr in a program does not bring the entire
-		program under the GPL
-	lpd 94-12-18 added conditionals for systems where ctype macros
-		don't handle 8-bit characters properly, suggested by
-		Francois Pinard <pinard@iro.umontreal.ca>;
-		removed --varargs switch (this is now the default)
-	lpd 94-10-10 removed CONFIG_BROKETS conditional
-	lpd 94-07-16 added some conditionals to help GNU `configure',
-		suggested by Francois Pinard <pinard@iro.umontreal.ca>;
-		properly erase prototype args in function parameters,
-		contributed by Jim Avera <jima@netcom.com>;
-		correct error in writeblanks (it shouldn't erase EOLs)
-	lpd 89-xx-xx original version

- * guarantee that more than one character can be pushed back with ungetc.
- * Looking at additional bytes would require one of these approaches:
- *     1) assume we can fseek() the input file (fails for piped input);
- *     2) assume we can push back more than one character (works in
- *        some C implementations, but unportable);
- *     3) provide our own buffering (breaks input readers that want to use
- *        stdio directly, such as the RLE library);
- * or  4) don't put back the data, and modify the input_init methods to assume
- *        they start reading after the start of file (also breaks RLE library).
- * #1 is attractive for MS-DOS but is untenable on Unix.
- *
- * The most portable solution for file types that can't be identified by their
- * first byte is to make the user tell us what they are.  This is also the
- * only approach for "raw" file types that contain only arbitrary values.
- * We presently apply this method for Targa files.  Most of the time Targa
- * files start with 0x00, so we recognize that case.  Potentially, however,
- * a Targa file could start with any byte value (byte 0 is the length of the
- * seldom-used ID field), so we provide a switch to force Targa input mode.

- * This file contains a command-line user interface for the JPEG decompressor.
- * It should work on any system with Unix- or MS-DOS-style command lines.
- *
- * Two different command line styles are permitted, depending on the
- * compile-time switch TWO_FILE_COMMANDLINE:
- *	djpeg [options]  inputfile outputfile
- *	djpeg [options]  [inputfile]
- * In the second style, output is always to standard output, which you'd
- * normally redirect to a file or pipe to some other program.  Input is
- * either from a named file or from standard input (typically redirected).
- * The second style is convenient on Unix but is unhelpful on systems that
- * don't support pipes.  Also, you MUST use the first style if your system
- * doesn't do binary I/O to stdin/stdout.
- * To simplify script writing, the "-outfile" switch is provided.  The syntax
- *	djpeg [options]  -outfile outputfile  inputfile
- * works regardless of which command line style is used.

- * error_exit routine.  To do this, we make a private extension of the
- * standard JPEG error handler object.  (If we were using C++, we'd say we
- * were making a subclass of the regular error handler.)

+ * ERROR HANDLING:
+ *
+ * The JPEG library's standard error handler (jerror.c) is divided into
+ * several "methods" which you can override individually.  This lets you
+ * adjust the behavior without duplicating a lot of code, which you might
+ * have to update with each future release.
+ *
+ * Our example here shows how to override the "error_exit" method so that
+ * control is returned to the library's caller when a fatal error occurs,
+ * rather than calling exit() as the standard error_exit method does.
+ *
+ * We use C's setjmp/longjmp facility to return control.  This means that the
+ * routine which calls the JPEG library must first execute a setjmp() call to
+ * establish the return point.  We want the replacement error_exit to do a
+ * longjmp().  But we need to make the setjmp buffer accessible to the
+ * error_exit routine.  To do this, we make a private extension of the
+ * standard JPEG error handler object.  (If we were using C++, we'd say we
+ * were making a subclass of the regular error handler.)
+ *
+ * Here's the extended error handler struct:

+ * code would risk an out-of-memory error.  However, in general we don't

+ * call jpeg_calc_output_dimensions().  See libjpeg.doc for more about this.
+ *
+ * Scanlines are returned in the same order as they appear in the JPEG file,
+ * which is standardly top-to-bottom.  If you must emit data bottom-to-top,
+ * you can use one of the virtual arrays provided by the JPEG memory manager
+ * to invert the data.  See wrbmp.c for an example.
+ *
+ * As with compression, some operating modes may require temporary files.
+ * On some systems you may need to set up a signal handler to ensure that
+ * temporary files are deleted if the program is interrupted.  See libjpeg.doc.

- * About virtual array management:
- *
- * The above "normal" array routines are only used to allocate strip buffers
- * (as wide as the image, but just a few rows high).  Full-image-sized buffers
- * are handled as "virtual" arrays.  The array is still accessed a strip at a
- * time, but the memory manager must save the whole array for repeated
- * accesses.  The intended implementation is that there is a strip buffer in
- * memory (as high as is possible given the desired memory limit), plus a
- * backing file that holds the rest of the array.
- *
- * The request_virt_array routines are told the total size of the image and
- * the maximum number of rows that will be accessed at once.  The in-memory
- * buffer must be at least as large as the maxaccess value.
- *
- * The request routines create control blocks but not the in-memory buffers.
- * That is postponed until realize_virt_arrays is called.  At that time the
- * total amount of space needed is known (approximately, anyway), so free
- * memory can be divided up fairly.
- *
- * The access_virt_array routines are responsible for making a specific strip
- * area accessible (after reading or writing the backing file, if necessary).
- * Note that the access routines are told whether the caller intends to modify
- * the accessed strip; during a read-only pass this saves having to rewrite
- * data to disk.  The access routines are also responsible for pre-zeroing
- * any newly accessed rows, if pre-zeroing was requested.
- *
- * In current usage, the access requests are usually for nonoverlapping
- * strips; that is, successive access start_row numbers differ by exactly
- * num_rows = maxaccess.  This means we can get good performance with simple
- * buffer dump/reload logic, by making the in-memory buffer be a multiple
- * of the access height; then there will never be accesses across bufferload
- * boundaries.  The code will still work with overlapping access requests,
- * but it doesn't handle bufferload overlaps very efficiently.

+ * About virtual array management:
+ *
+ * The above "normal" array routines are only used to allocate strip buffers
+ * (as wide as the image, but just a few rows high).  Full-image-sized buffers
+ * are handled as "virtual" arrays.  The array is still accessed a strip at a
+ * time, but the memory manager must save the whole array for repeated
+ * accesses.  The intended implementation is that there is a strip buffer in
+ * memory (as high as is possible given the desired memory limit), plus a
+ * backing file that holds the rest of the array.
+ *
+ * The request_virt_array routines are told the total size of the image and
+ * the maximum number of rows that will be accessed at once.  The in-memory
+ * buffer must be at least as large as the maxaccess value.
+ *
+ * The request routines create control blocks but not the in-memory buffers.
+ * That is postponed until realize_virt_arrays is called.  At that time the
+ * total amount of space needed is known (approximately, anyway), so free
+ * memory can be divided up fairly.
+ *
+ * The access_virt_array routines are responsible for making a specific strip
+ * area accessible (after reading or writing the backing file, if necessary).
+ * Note that the access routines are told whether the caller intends to modify
+ * the accessed strip; during a read-only pass this saves having to rewrite
+ * data to disk.  The access routines are also responsible for pre-zeroing
+ * any newly accessed rows, if pre-zeroing was requested.
+ *
+ * In current usage, the access requests are usually for nonoverlapping
+ * strips; that is, successive access start_row numbers differ by exactly
+ * num_rows = maxaccess.  This means we can get good performance with simple
+ * buffer dump/reload logic, by making the in-memory buffer be a multiple
+ * of the access height; then there will never be accesses across bufferload
+ * boundaries.  The code will still work with overlapping access requests,
+ * but it doesn't handle bufferload overlaps very efficiently.

+# Documentation
+
+The most up-to-date documentation is supposed to be available on the
+[BearSSL Web site](https://www.bearssl.org/).
+
+# Disclaimer
+
+BearSSL is considered beta-level software. Most planned functionalities
+are implemented; new evolution may still break both source and binary
+compatibility.
+
+Using BearSSL for production purposes would be a relatively bold but not
+utterly crazy move. BearSSL is free, open-source software, provided
+without any guarantee of fitness or reliability. That being said, it
+appears to behave properly, and only minor issues have been found (and
+fixed) so far. You are encourage to inspect its API and code for
+learning, testing and possibly contributing.
+
+The usage license is explicited in the `LICENSE.txt` file. This is the
+"MIT license". It can be summarised in the following way:
+
+ - You can use and reuse the library as you wish, and modify it, and
+   integrate it in your own code, and distribute it as is or in any
+   modified form, and so on.
+
+ - The only obligation that the license terms put upon you is that you
+   acknowledge and make it clear that if anything breaks, it is not my
+   fault, and I am not liable for anything, regardless of the type and
+   amount of collateral damage. The license terms say that the copyright
+   notice "shall be included in all copies or substantial portions of
+   the Software": this is how the disclaimer is "made explicit".
+   Basically, I have put it in every source file, so just keep it there.
+
+# Installation
+
+Right now, BearSSL is a simple library, along with a few test and debug
+command-line tools. There is no installer yet. The library _can_ be
+compiled as a shared library on some systems, but since the binary API
+is not fully stabilised, this is not a very good idea to do that right
+now.
+
+To compile the code, just type `make`. This will try to use sane
+"default" values. On a Windows system with Visual Studio, run a console
+with the environment initialised for a specific version of the C compiler,
+and type `nmake`.
+
+To override the default settings, create a custom configuration file in
+the `conf` directory, and invoke `make` (or `nmake`) with an explicit
+`CONF=` parameter. For instance, to use the provided `samd20.mk`
+configuration file (that targets cross-compilation for an Atmel board
+that features a Cortex-M0+ CPU), type:
+
+    make CONF=samd20
+
+The `conf/samd20.mk` file includes the `Unix.mk` file and then overrides
+some of the parameters, including the destination directory. Any custom
+configuration can be made the same way.
+
+Some compile-time options can be set through macros, either on the
+compiler command-line, or in the `src/config.h` file. See the comments
+in that file. Some settings are autodetected but they can still be
+explicitly overridden.
+
+When compilation is done, the library (static and DLL, when appropriate)
+and the command-line tools can be found in the designated build
+directory (by default named `build`). The public headers (to be used
+by applications linked against BearSSL) are in the `inc/` directory.
+
+To run the tests:
+
+  - `testcrypto all` runs the cryptographic tests (test vectors on all
+    implemented cryptogaphic functions). It can be slow. You can also
+    run a selection of the tests by providing their names (run
+    `testcrypto` without any parameter to see the available names).
+
+  - `testspeed all` runs a number of performance benchmarks, there again
+    on cryptographic functions. It gives a taste of how things go on the
+    current platform. As for `testcrypto`, specific named benchmarks can
+    be executed.
+
+  - `testx509` runs X.509 validation tests. The test certificates are
+    all in `test/x509/`.
+
+The `brssl` command-line tool produced in the build directory is a
+stand-alone binary. It can exercise some of the functionalities of
+BearSSL, in particular running a test SSL client or server. It is not
+meant for production purposes (e.g. the SSL client has a mode where it
+disregards the inability to validate the server's certificate, which is
+inherently unsafe, but convenient for debug).
+
+**Using the library** means writing some application code that invokes
+it, and linking with the static library. The header files are all in the
+`inc` directory; copy them wherever makes sense (e.g. in the
+`/usr/local/include` directory). The library itself (`libbearssl.a`) is
+what you link against.
+
+Alternatively, you may want to copy the source files directly into your
+own application code. This will make integrating ulterior versions of
+BearSSL more difficult. If you still want to go down that road, then
+simply copy all the `*.h` and `*.c` files from the `src` and `inc`
+directories into your application source code. In the BearSSL source
+archive, the source files are segregated into various sub-directories,
+but this is for my convenience only. There is no technical requirement
+for that, and all files can be dumped together in a simple directory.
+
+Dependencies are simple and systematic:
+
+  - Each `*.c` file includes `inner.h`
+  - `inner.h` includes `config.h` and `bearssl.h`
+  - `bearssl.h` includes the other `bearssl_*.h`
+
+# Versioning
+
+I follow this simple version numbering scheme:
+
+ - Version numbers are `x.y` or `x.y.z` where `x`, `y` and `z` are
+   decimal integers (possibly greater than 10). When the `.z` part is
+   missing, it is equivalent to `.0`.
+
+ - Backward compatibility is maintained, at both source and binary levels,
+   for each major version: this means that if some application code was
+   designed for version `x.y`, then it should compile, link and run
+   properly with any version `x.y'` for any `y'` greater than `y`.
+
+   The major version `0` is an exception. You shall not expect that any
+   version that starts with `0.` offers any kind of compatibility,
+   either source or binary, with any other `0.` version. (Of course I
+   will try to maintain some decent level of source compatibility, but I
+   make no promise in that respect. Since the API uses caller-allocated
+   context structures, I already know that binary compatibility _will_
+   be broken.)
+
+ - Sub-versions (the `y` part) are about added functionality. That is,
+   it can be expected that `1.3` will contain some extra functions when
+   compared to `1.2`. The next version level (the `z` part) is for
+   bugfixes that do not add any functionality.

+ *
+ * # API Layout
+ *
+ * The functions and structures defined by the BearSSL API are located
+ * in various header files:
+ *
+ * | Header file     | Elements                                          |
+ * | :-------------- | :------------------------------------------------ |

+ * | bearssl_kdf.h   | Key Derivation Functions                          |
+ * | bearssl_rand.h  | Pseudorandom byte generators                      |
+ * | bearssl_prf.h   | PRF implementations (for SSL/TLS)                 |
+ * | bearssl_block.h | Symmetric encryption                              |
+ * | bearssl_aead.h  | AEAD algorithms (combined encryption + MAC)       |
+ * | bearssl_rsa.h   | RSA encryption and signatures                     |
+ * | bearssl_ec.h    | Elliptic curves support (including ECDSA)         |
+ * | bearssl_ssl.h   | SSL/TLS engine interface                          |
+ * | bearssl_x509.h  | X.509 certificate decoding and validation         |
+ * | bearssl_pem.h   | Base64/PEM decoding support functions             |
+ *
+ * Applications using BearSSL are supposed to simply include `bearssl.h`
+ * as follows:
+ *
+ *     #include <bearssl.h>
+ *
+ * The `bearssl.h` file itself includes all the other header files. It is
+ * possible to include specific header files, but it has no practical
+ * advantage for the application. The API is separated into separate
+ * header files only for documentation convenience.
+ *
+ *
+ * # Conventions
+ *
+ * ## MUST and SHALL
+ *
+ * In all descriptions, the usual "MUST", "SHALL", "MAY",... terminology
+ * is used. Failure to meet requirements expressed with a "MUST" or
+ * "SHALL" implies undefined behaviour, which means that segmentation
+ * faults, buffer overflows, and other similar adverse events, may occur.
+ *
+ * In general, BearSSL is not very forgiving of programming errors, and
+ * does not include much failsafes or error reporting when the problem
+ * does not arise from external transient conditions, and can be fixed
+ * only in the application code. This is done so in order to make the
+ * total code footprint lighter.
+ *
+ *
+ * ## `NULL` values
+ *
+ * Function parameters with a pointer type shall not be `NULL` unless
+ * explicitly authorised by the documentation. As an exception, when
+ * the pointer aims at a sequence of bytes and is accompanied with
+ * a length parameter, and the length is zero (meaning that there is
+ * no byte at all to retrieve), then the pointer may be `NULL` even if
+ * not explicitly allowed.
+ *
+ *
+ * ## Memory Allocation
+ *
+ * BearSSL does not perform dynamic memory allocation. This implies that
+ * for any functionality that requires a non-transient state, the caller
+ * is responsible for allocating the relevant context structure. Such
+ * allocation can be done in any appropriate area, including static data
+ * segments, the heap, and the stack, provided that proper alignment is
+ * respected. The header files define these context structures
+ * (including size and contents), so the C compiler should handle
+ * alignment automatically.
+ *
+ * Since there is no dynamic resource allocation, there is also nothing to
+ * release. When the calling code is done with a BearSSL feature, it
+ * may simple release the context structures it allocated itself, with
+ * no "close function" to call. If the context structures were allocated
+ * on the stack (as local variables), then even that release operation is
+ * implicit.
+ *
+ *
+ * ## Structure Contents
+ *
+ * Except when explicitly indicated, structure contents are opaque: they
+ * are included in the header files so that calling code may know the
+ * structure sizes and alignment requirements, but callers SHALL NOT
+ * access individual fields directly. For fields that are supposed to
+ * be read from or written to, the API defines accessor functions (the
+ * simplest of these accessor functions are defined as `static inline`
+ * functions, and the C compiler will optimise them away).
+ *
+ *
+ * # API Usage
+ *
+ * BearSSL usage for running a SSL/TLS client or server is described
+ * on the [BearSSL Web site](https://www.bearssl.org/api1.html). The
+ * BearSSL source archive also comes with sample code.

+ * # Authenticated Encryption with Additional Data
+ *
+ * This file documents the API for AEAD encryption.
+ *
+ *
+ * ## Procedural API
+ *
+ * An AEAD algorithm processes messages and provides confidentiality
+ * (encryption) and checked integrity (MAC). It uses the following
+ * parameters:
+ *
+ *   - A symmetric key. Exact size depends on the AEAD algorithm.
+ *
+ *   - A nonce (IV). Size depends on the AEAD algorithm; for most
+ *     algorithms, it is crucial for security that any given nonce
+ *     value is never used twice for the same key and distinct
+ *     messages.
+ *
+ *   - Data to encrypt and protect.
+ *
+ *   - Additional authenticated data, which is covered by the MAC but
+ *     otherwise left untouched (i.e. not encrypted).
+ *
+ * The AEAD algorithm encrypts the data, and produces an authentication
+ * tag. It is assumed that the encrypted data, the tag, the additional
+ * authenticated data and the nonce are sent to the receiver; the
+ * additional data and the nonce may be implicit (e.g. using elements of
+ * the underlying transport protocol, such as record sequence numbers).
+ * The receiver will recompute the tag value and compare it with the one
+ * received; if they match, then the data is correct, and can be
+ * decrypted and used; otherwise, at least one of the elements was
+ * altered in transit, normally leading to wholesale rejection of the
+ * complete message.
+ *
+ * For each AEAD algorithm, identified by a symbolic name (hereafter
+ * denoted as "`xxx`"), the following functions are defined:
+ *
+ *   - `br_xxx_init()`
+ *
+ *     Initialise the AEAD algorithm, on a provided context structure.
+ *     Exact parameters depend on the algorithm, and may include
+ *     pointers to extra implementations and context structures. The
+ *     secret key is provided at this point, either directly or
+ *     indirectly.
+ *
+ *   - `br_xxx_reset()`
+ *
+ *     Start a new AEAD computation. The nonce value is provided as
+ *     parameter to this function.
+ *
+ *   - `br_xxx_aad_inject()`
+ *
+ *     Inject some additional authenticated data. Additional data may
+ *     be provided in several chunks of arbitrary length.
+ *
+ *   - `br_xxx_flip()`
+ *
+ *     This function MUST be called after injecting all additional
+ *     authenticated data, and before beginning to encrypt the plaintext
+ *     (or decrypt the ciphertext).
+ *
+ *   - `br_xxx_run()`
+ *
+ *     Process some plaintext (to encrypt) or ciphertext (to decrypt).
+ *     Encryption/decryption is done in place. Data may be provided in
+ *     several chunks of arbitrary length.
+ *
+ *   - `br_xxx_get_tag()`
+ *
+ *     Compute the authentication tag. All message data (encrypted or
+ *     decrypted) must have been injected at that point. Also, this
+ *     call may modify internal context elements, so it may be called
+ *     only once for a given AEAD computation.
+ *
+ *   - `br_xxx_check_tag()`
+ *
+ *     An alternative to `br_xxx_get_tag()`, meant to be used by the
+ *     receiver: the authentication tag is internally recomputed, and
+ *     compared with the one provided as parameter.
+ *
+ * This API makes the following assumptions on the AEAD algorithm:
+ *
+ *   - Encryption does not expand the size of the ciphertext; there is
+ *     no padding. This is true of most modern AEAD modes such as GCM.
+ *
+ *   - The additional authenticated data must be processed first,
+ *     before the encrypted/decrypted data.
+ *
+ *   - Nonce, plaintext and additional authenticated data all consist
+ *     in an integral number of bytes. There is no provision to use
+ *     elements whose length in bits is not a multiple of 8.
+ *
+ * Each AEAD algorithm has its own requirements and limits on the sizes
+ * of additional data and plaintext. This API does not provide any
+ * way to report invalid usage; it is up to the caller to ensure that
+ * the provided key, nonce, and data elements all fit the algorithm's
+ * requirements.
+ *
+ *
+ * ## Object-Oriented API
+ *
+ * Each context structure begins with a field (called `vtable`) that
+ * points to an instance of a structure that references the relevant
+ * functions through pointers. Each such structure contains the
+ * following:
+ *
+ *   - `reset`
+ *
+ *     Pointer to the reset function, that allows starting a new
+ *     computation.
+ *
+ *   - `aad_inject`
+ *
+ *     Pointer to the additional authenticated data injection function.
+ *
+ *   - `flip`
+ *
+ *     Pointer to the function that transitions from additional data
+ *     to main message data processing.
+ *
+ *   - `get_tag`
+ *
+ *     Pointer to the function that computes and returns the tag.
+ *
+ *   - `check_tag`
+ *
+ *     Pointer to the function that computes and verifies the tag against
+ *     a received value.
+ *
+ * Note that there is no OOP method for context initialisation: the
+ * various AEAD algorithms have different requirements that would not
+ * map well to a single initialisation API.
+ *
+ * The OOP API is not provided for CCM, due to its specific requirements
+ * (length of plaintext must be known in advance).

+ * # Block Ciphers and Symmetric Ciphers
+ *
+ * This file documents the API for block ciphers and other symmetric
+ * ciphers.
+ *
+ *
+ * ## Procedural API
+ *
+ * For a block cipher implementation, up to three separate sets of
+ * functions are provided, for CBC encryption, CBC decryption, and CTR
+ * encryption/decryption. Each set has its own context structure,
+ * initialised with the encryption key.
+ *
+ * For CBC encryption and decryption, the data to encrypt or decrypt is
+ * referenced as a sequence of blocks. The implementations assume that
+ * there is no partial block; no padding is applied or removed. The
+ * caller is responsible for handling any kind of padding.
+ *
+ * Function for CTR encryption are defined only for block ciphers with
+ * blocks of 16 bytes or more (i.e. AES, but not DES/3DES).
+ *
+ * Each implemented block cipher is identified by an "internal name"
+ * from which are derived the names of structures and functions that
+ * implement the cipher. For the block cipher of internal name "`xxx`",
+ * the following are defined:
+ *
+ *   - `br_xxx_BLOCK_SIZE`
+ *
+ *     A macro that evaluates to the block size (in bytes) of the
+ *     cipher. For all implemented block ciphers, this value is a
+ *     power of two.
+ *
+ *   - `br_xxx_cbcenc_keys`
+ *
+ *     Context structure that contains the subkeys resulting from the key
+ *     expansion. These subkeys are appropriate for CBC encryption. The
+ *     structure first field is called `vtable` and points to the
+ *     appropriate OOP structure.
+ *
+ *   - `br_xxx_cbcenc_init(br_xxx_cbcenc_keys *ctx, const void *key, size_t len)`
+ *
+ *     Perform key expansion: subkeys for CBC encryption are computed and
+ *     written in the provided context structure. The key length MUST be
+ *     adequate for the implemented block cipher. This function also sets
+ *     the `vtable` field.
+ *
+ *   - `br_xxx_cbcenc_run(const br_xxx_cbcenc_keys *ctx, void *iv, void *data, size_t len)`
+ *
+ *     Perform CBC encryption of `len` bytes, in place. The encrypted data
+ *     replaces the cleartext. `len` MUST be a multiple of the block length
+ *     (if it is not, the function may loop forever or overflow a buffer).
+ *     The IV is provided with the `iv` pointer; it is also updated with
+ *     a copy of the last encrypted block.
+ *
+ *   - `br_xxx_cbcdec_keys`
+ *
+ *     Context structure that contains the subkeys resulting from the key
+ *     expansion. These subkeys are appropriate for CBC decryption. The
+ *     structure first field is called `vtable` and points to the
+ *     appropriate OOP structure.
+ *
+ *   - `br_xxx_cbcdec_init(br_xxx_cbcenc_keys *ctx, const void *key, size_t len)`
+ *
+ *     Perform key expansion: subkeys for CBC decryption are computed and
+ *     written in the provided context structure. The key length MUST be
+ *     adequate for the implemented block cipher. This function also sets
+ *     the `vtable` field.
+ *
+ *   - `br_xxx_cbcdec_run(const br_xxx_cbcdec_keys *ctx, void *iv, void *data, size_t num_blocks)`
+ *
+ *     Perform CBC decryption of `len` bytes, in place. The decrypted data
+ *     replaces the ciphertext. `len` MUST be a multiple of the block length
+ *     (if it is not, the function may loop forever or overflow a buffer).
+ *     The IV is provided with the `iv` pointer; it is also updated with
+ *     a copy of the last _encrypted_ block.
+ *
+ *   - `br_xxx_ctr_keys`
+ *
+ *     Context structure that contains the subkeys resulting from the key
+ *     expansion. These subkeys are appropriate for CTR encryption and
+ *     decryption. The structure first field is called `vtable` and
+ *     points to the appropriate OOP structure.
+ *
+ *   - `br_xxx_ctr_init(br_xxx_ctr_keys *ctx, const void *key, size_t len)`
+ *
+ *     Perform key expansion: subkeys for CTR encryption and decryption
+ *     are computed and written in the provided context structure. The
+ *     key length MUST be adequate for the implemented block cipher. This
+ *     function also sets the `vtable` field.
+ *
+ *   - `br_xxx_ctr_run(const br_xxx_ctr_keys *ctx, const void *iv, uint32_t cc, void *data, size_t len)` (returns `uint32_t`)
+ *
+ *     Perform CTR encryption/decryption of some data. Processing is done
+ *     "in place" (the output data replaces the input data). This function
+ *     implements the "standard incrementing function" from NIST SP800-38A,
+ *     annex B: the IV length shall be 4 bytes less than the block size
+ *     (i.e. 12 bytes for AES) and the counter is the 32-bit value starting
+ *     with `cc`. The data length (`len`) is not necessarily a multiple of
+ *     the block size. The new counter value is returned, which supports
+ *     chunked processing, provided that each chunk length (except possibly
+ *     the last one) is a multiple of the block size.
+ *
+ *   - `br_xxx_ctrcbc_keys`
+ *
+ *     Context structure that contains the subkeys resulting from the
+ *     key expansion. These subkeys are appropriate for doing combined
+ *     CTR encryption/decryption and CBC-MAC, as used in the CCM and EAX
+ *     authenticated encryption modes. The structure first field is
+ *     called `vtable` and points to the appropriate OOP structure.
+ *
+ *   - `br_xxx_ctrcbc_init(br_xxx_ctr_keys *ctx, const void *key, size_t len)`
+ *
+ *     Perform key expansion: subkeys for combined CTR
+ *     encryption/decryption and CBC-MAC are computed and written in the
+ *     provided context structure. The key length MUST be adequate for
+ *     the implemented block cipher. This function also sets the
+ *     `vtable` field.
+ *
+ *   - `br_xxx_ctrcbc_encrypt(const br_xxx_ctrcbc_keys *ctx, void *ctr, void *cbcmac, void *data, size_t len)`
+ *
+ *     Perform CTR encryption of some data, and CBC-MAC. Processing is
+ *     done "in place" (the output data replaces the input data). This
+ *     function applies CTR encryption on the data, using a full
+ *     block-size counter (i.e. for 128-bit blocks, the counter is
+ *     incremented as a 128-bit value). The 'ctr' array contains the
+ *     initial value for the counter (used in the first block) and it is
+ *     updated with the new value after data processing. The 'cbcmac'
+ *     value shall point to a block-sized value which is used as IV for
+ *     CBC-MAC, computed over the encrypted data (output of CTR
+ *     encryption); the resulting CBC-MAC is written over 'cbcmac' on
+ *     output.
+ *
+ *     The data length MUST be a multiple of the block size.
+ *
+ *   - `br_xxx_ctrcbc_decrypt(const br_xxx_ctrcbc_keys *ctx, void *ctr, void *cbcmac, void *data, size_t len)`
+ *
+ *     Perform CTR decryption of some data, and CBC-MAC. Processing is
+ *     done "in place" (the output data replaces the input data). This
+ *     function applies CTR decryption on the data, using a full
+ *     block-size counter (i.e. for 128-bit blocks, the counter is
+ *     incremented as a 128-bit value). The 'ctr' array contains the
+ *     initial value for the counter (used in the first block) and it is
+ *     updated with the new value after data processing. The 'cbcmac'
+ *     value shall point to a block-sized value which is used as IV for
+ *     CBC-MAC, computed over the encrypted data (input of CTR
+ *     encryption); the resulting CBC-MAC is written over 'cbcmac' on
+ *     output.
+ *
+ *     The data length MUST be a multiple of the block size.
+ *
+ *   - `br_xxx_ctrcbc_ctr(const br_xxx_ctrcbc_keys *ctx, void *ctr, void *data, size_t len)`
+ *
+ *     Perform CTR encryption or decryption of the provided data. The
+ *     data is processed "in place" (the output data replaces the input
+ *     data). A full block-sized counter is applied (i.e. for 128-bit
+ *     blocks, the counter is incremented as a 128-bit value). The 'ctr'
+ *     array contains the initial value for the counter (used in the
+ *     first block), and it is updated with the new value after data
+ *     processing.
+ *
+ *     The data length MUST be a multiple of the block size.
+ *
+ *   - `br_xxx_ctrcbc_mac(const br_xxx_ctrcbc_keys *ctx, void *cbcmac, const void *data, size_t len)`
+ *
+ *     Compute CBC-MAC over the provided data. The IV for CBC-MAC is
+ *     provided as 'cbcmac'; the output is written over the same array.
+ *     The data itself is untouched. The data length MUST be a multiple
+ *     of the block size.
+ *
+ *
+ * It shall be noted that the key expansion functions return `void`. If
+ * the provided key length is not allowed, then there will be no error
+ * reporting; implementations need not validate the key length, thus an
+ * invalid key length may result in undefined behaviour (e.g. buffer
+ * overflow).
+ *
+ * Subkey structures contain no interior pointer, and no external
+ * resources are allocated upon key expansion. They can thus be
+ * discarded without any explicit deallocation.
+ *
+ *
+ * ## Object-Oriented API
+ *
+ * Each context structure begins with a field (called `vtable`) that
+ * points to an instance of a structure that references the relevant
+ * functions through pointers. Each such structure contains the
+ * following:
+ *
+ *   - `context_size`
+ *
+ *     The size (in bytes) of the context structure for subkeys.
+ *
+ *   - `block_size`
+ *
+ *     The cipher block size (in bytes).
+ *
+ *   - `log_block_size`
+ *
+ *     The base-2 logarithm of cipher block size (e.g. 4 for blocks
+ *     of 16 bytes).
+ *
+ *   - `init`
+ *
+ *     Pointer to the key expansion function.
+ *
+ *   - `run`
+ *
+ *     Pointer to the encryption/decryption function.
+ *
+ * For combined CTR/CBC-MAC encryption, the `vtable` has a slightly
+ * different structure:
+ *
+ *   - `context_size`
+ *
+ *     The size (in bytes) of the context structure for subkeys.
+ *
+ *   - `block_size`
+ *
+ *     The cipher block size (in bytes).
+ *
+ *   - `log_block_size`
+ *
+ *     The base-2 logarithm of cipher block size (e.g. 4 for blocks
+ *     of 16 bytes).
+ *
+ *   - `init`
+ *
+ *     Pointer to the key expansion function.
+ *
+ *   - `encrypt`
+ *
+ *     Pointer to the CTR encryption + CBC-MAC function.
+ *
+ *   - `decrypt`
+ *
+ *     Pointer to the CTR decryption + CBC-MAC function.
+ *
+ *   - `ctr`
+ *
+ *     Pointer to the CTR encryption/decryption function.
+ *
+ *   - `mac`
+ *
+ *     Pointer to the CBC-MAC function.
+ *
+ * For block cipher "`xxx`", static, constant instances of these
+ * structures are defined, under the names:
+ *
+ *   - `br_xxx_cbcenc_vtable`
+ *   - `br_xxx_cbcdec_vtable`
+ *   - `br_xxx_ctr_vtable`
+ *   - `br_xxx_ctrcbc_vtable`
+ *
+ *
+ * ## Implemented Block Ciphers
+ * 
+ * Provided implementations are:
+ *
+ * | Name      | Function | Block Size (bytes) | Key lengths (bytes) |
+ * | :-------- | :------- | :----------------: | :-----------------: |
+ * | aes_big   | AES      |        16          | 16, 24 and 32       |
+ * | aes_small | AES      |        16          | 16, 24 and 32       |
+ * | aes_ct    | AES      |        16          | 16, 24 and 32       |
+ * | aes_ct64  | AES      |        16          | 16, 24 and 32       |
+ * | aes_x86ni | AES      |        16          | 16, 24 and 32       |
+ * | aes_pwr8  | AES      |        16          | 16, 24 and 32       |
+ * | des_ct    | DES/3DES |         8          | 8, 16 and 24        |
+ * | des_tab   | DES/3DES |         8          | 8, 16 and 24        |
+ *
+ * **Note:** DES/3DES nominally uses keys of 64, 128 and 192 bits (i.e. 8,
+ * 16 and 24 bytes), but some of the bits are ignored by the algorithm, so
+ * the _effective_ key lengths, from a security point of view, are 56,
+ * 112 and 168 bits, respectively.
+ *
+ * `aes_big` is a "classical" AES implementation, using tables. It
+ * is fast but not constant-time, since it makes data-dependent array
+ * accesses.
+ *
+ * `aes_small` is an AES implementation optimized for code size. It
+ * is substantially slower than `aes_big`; it is not constant-time
+ * either.
+ *
+ * `aes_ct` is a constant-time implementation of AES; its code is about
+ * as big as that of `aes_big`, while its performance is comparable to
+ * that of `aes_small`. However, it is constant-time. This
+ * implementation should thus be considered to be the "default" AES in
+ * BearSSL, to be used unless the operational context guarantees that a
+ * non-constant-time implementation is safe, or an architecture-specific
+ * constant-time implementation can be used (e.g. using dedicated
+ * hardware opcodes).
+ *
+ * `aes_ct64` is another constant-time implementation of AES. It is
+ * similar to `aes_ct` but uses 64-bit values. On 32-bit machines,
+ * `aes_ct64` is not faster than `aes_ct`, often a bit slower, and has
+ * a larger footprint; however, on 64-bit architectures, `aes_ct64`
+ * is typically twice faster than `aes_ct` for modes that allow parallel
+ * operations (i.e. CTR, and CBC decryption, but not CBC encryption).
+ *
+ * `aes_x86ni` exists only on x86 architectures (32-bit and 64-bit). It
+ * uses the AES-NI opcodes when available.
+ *
+ * `aes_pwr8` exists only on PowerPC / POWER architectures (32-bit and
+ * 64-bit, both little-endian and big-endian). It uses the AES opcodes
+ * present in POWER8 and later.
+ *
+ * `des_tab` is a classic, table-based implementation of DES/3DES. It
+ * is not constant-time.
+ *
+ * `des_ct` is an constant-time implementation of DES/3DES. It is
+ * substantially slower than `des_tab`.
+ *
+ * ## ChaCha20 and Poly1305
+ *
+ * ChaCha20 is a stream cipher. Poly1305 is a MAC algorithm. They
+ * are described in [RFC 7539](https://tools.ietf.org/html/rfc7539).
+ *
+ * Two function pointer types are defined:
+ *
+ *   - `br_chacha20_run` describes a function that implements ChaCha20
+ *     only.
+ *
+ *   - `br_poly1305_run` describes an implementation of Poly1305,
+ *     in the AEAD combination with ChaCha20 specified in RFC 7539
+ *     (the ChaCha20 implementation is provided as a function pointer).
+ *
+ * `chacha20_ct` is a straightforward implementation of ChaCha20 in
+ * plain C; it is constant-time, small, and reasonably fast.
+ *
+ * `chacha20_sse2` leverages SSE2 opcodes (on x86 architectures that
+ * support these opcodes). It is faster than `chacha20_ct`.
+ *
+ * `poly1305_ctmul` is an implementation of the ChaCha20+Poly1305 AEAD
+ * construction, where the Poly1305 part is performed with mixed 32-bit
+ * multiplications (operands are 32-bit, result is 64-bit).
+ *
+ * `poly1305_ctmul32` implements ChaCha20+Poly1305 using pure 32-bit
+ * multiplications (32-bit operands, 32-bit result). It is slower than
+ * `poly1305_ctmul`, except on some specific architectures such as
+ * the ARM Cortex M0+.
+ *
+ * `poly1305_ctmulq` implements ChaCha20+Poly1305 with mixed 64-bit
+ * multiplications (operands are 64-bit, result is 128-bit) on 64-bit
+ * platforms that support such operations.
+ *
+ * `poly1305_i15` implements ChaCha20+Poly1305 with the generic "i15"
+ * big integer implementation. It is meant mostly for testing purposes,
+ * although it can help with saving a few hundred bytes of code footprint
+ * on systems where code size is scarce.

+ * # Elliptic Curves
+ *
+ * This file documents the EC implementations provided with BearSSL, and
+ * ECDSA.
+ *
+ * ## Elliptic Curve API
+ *
+ * Only "named curves" are supported. Each EC implementation supports
+ * one or several named curves, identified by symbolic identifiers.
+ * These identifiers are small integers, that correspond to the values
+ * registered by the
+ * [IANA](http://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-8).
+ *
+ * Since all currently defined elliptic curve identifiers are in the 0..31
+ * range, it is convenient to encode support of some curves in a 32-bit
+ * word, such that bit x corresponds to curve of identifier x.
+ *
+ * An EC implementation is incarnated by a `br_ec_impl` instance, that
+ * offers the following fields:
+ *
+ *   - `supported_curves`
+ *
+ *      A 32-bit word that documents the identifiers of the curves supported
+ *      by this implementation.
+ *
+ *   - `generator()`
+ *
+ *      Callback method that returns a pointer to the conventional generator
+ *      point for that curve.
+ *
+ *   - `order()`
+ *
+ *      Callback method that returns a pointer to the subgroup order for
+ *      that curve. That value uses unsigned big-endian encoding.
+ *
+ *   - `xoff()`
+ *
+ *      Callback method that returns the offset and length of the X
+ *      coordinate in an encoded point.
+ *
+ *   - `mul()`
+ *
+ *      Multiply a curve point with an integer.
+ *
+ *   - `mulgen()`
+ *
+ *      Multiply the curve generator with an integer. This may be faster
+ *      than the generic `mul()`.
+ *
+ *   - `muladd()`
+ *
+ *      Multiply two curve points by two integers, and return the sum of
+ *      the two products.
+ *
+ * All curve points are represented in uncompressed format. The `mul()`
+ * and `muladd()` methods take care to validate that the provided points
+ * are really part of the relevant curve subgroup.
+ *
+ * For all point multiplication functions, the following holds:
+ *
+ *   - Functions validate that the provided points are valid members
+ *     of the relevant curve subgroup. An error is reported if that is
+ *     not the case.
+ *
+ *   - Processing is constant-time, even if the point operands are not
+ *     valid. This holds for both the source and resulting points, and
+ *     the multipliers (integers). Only the byte length of the provided
+ *     multiplier arrays (not their actual value length in bits) may
+ *     leak through timing-based side channels.
+ *
+ *   - The multipliers (integers) MUST be lower than the subgroup order.
+ *     If this property is not met, then the result is indeterminate,
+ *     but an error value is not ncessearily returned.
+ * 
+ *
+ * ## ECDSA
+ *
+ * ECDSA signatures have two standard formats, called "raw" and "asn1".
+ * Internally, such a signature is a pair of modular integers `(r,s)`.
+ * The "raw" format is the concatenation of the unsigned big-endian
+ * encodings of these two integers, possibly left-padded with zeros so
+ * that they have the same encoded length. The "asn1" format is the
+ * DER encoding of an ASN.1 structure that contains the two integer
+ * values:
+ *
+ *     ECDSASignature ::= SEQUENCE {
+ *         r   INTEGER,
+ *         s   INTEGER
+ *     }
+ *
+ * In general, in all of X.509 and SSL/TLS, the "asn1" format is used.
+ * BearSSL offers ECDSA implementations for both formats; conversion
+ * functions between the two formats are also provided. Conversion of a
+ * "raw" format signature into "asn1" may enlarge a signature by no more
+ * than 9 bytes for all supported curves; conversely, conversion of an
+ * "asn1" signature to "raw" may expand the signature but the "raw"
+ * length will never be more than twice the length of the "asn1" length
+ * (and usually it will be shorter).
+ *
+ * Note that for a given signature, the "raw" format is not fully
+ * deterministic, in that it does not enforce a minimal common length.
+ */

+ * # Hash Functions
+ *
+ * This file documents the API for hash functions.
+ *
+ *
+ * ## Procedural API
+ *
+ * For each implemented hash function, of name "`xxx`", the following
+ * elements are defined:
+ *
+ *   - `br_xxx_vtable`
+ *
+ *     An externally defined instance of `br_hash_class`.
+ *
+ *   - `br_xxx_SIZE`
+ *
+ *     A macro that evaluates to the output size (in bytes) of the
+ *     hash function.
+ *
+ *   - `br_xxx_ID`
+ *
+ *     A macro that evaluates to a symbolic identifier for the hash
+ *     function. Such identifiers are used with HMAC and signature
+ *     algorithm implementations.
+ *
+ *     NOTE: for the "standard" hash functions defined in [the TLS
+ *     standard](https://tools.ietf.org/html/rfc5246#section-7.4.1.4.1),
+ *     the symbolic identifiers match the constants used in TLS, i.e.
+ *     1 to 6 for MD5, SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512,
+ *     respectively.
+ *
+ *   - `br_xxx_context`
+ *
+ *     Context for an ongoing computation. It is allocated by the
+ *     caller, and a pointer to it is passed to all functions. A
+ *     context contains no interior pointer, so it can be moved around
+ *     and cloned (with a simple `memcpy()` or equivalent) in order to
+ *     capture the function state at some point. Computations that use
+ *     distinct context structures are independent of each other. The
+ *     first field of `br_xxx_context` is always a pointer to the
+ *     `br_xxx_vtable` structure; `br_xxx_init()` sets that pointer.
+ *
+ *   - `br_xxx_init(br_xxx_context *ctx)`
+ *
+ *     Initialise the provided context. Previous contents of the structure
+ *     are ignored. This calls resets the context to the start of a new
+ *     hash computation; it also sets the first field of the context
+ *     structure (called `vtable`) to a pointer to the statically
+ *     allocated constant `br_xxx_vtable` structure.
+ *
+ *   - `br_xxx_update(br_xxx_context *ctx, const void *data, size_t len)`
+ *
+ *     Add some more bytes to the hash computation represented by the
+ *     provided context.
+ *
+ *   - `br_xxx_out(const br_xxx_context *ctx, void *out)`
+ *
+ *     Complete the hash computation and write the result in the provided
+ *     buffer. The output buffer MUST be large enough to accommodate the
+ *     result. The context is NOT modified by this operation, so this
+ *     function can be used to get a "partial hash" while still keeping
+ *     the possibility of adding more bytes to the input.
+ *
+ *   - `br_xxx_state(const br_xxx_context *ctx, void *out)`
+ *
+ *     Get a copy of the "current state" for the computation so far. For
+ *     MD functions (MD5, SHA-1, SHA-2 family), this is the running state
+ *     resulting from the processing of the last complete input block.
+ *     Returned value is the current input length (in bytes).
+ *
+ *   - `br_xxx_set_state(br_xxx_context *ctx, const void *stb, uint64_t count)`
+ *
+ *     Set the internal state to the provided values. The 'stb' and
+ *     'count' values shall match that which was obtained from
+ *     `br_xxx_state()`. This restores the hash state only if the state
+ *     values were at an appropriate block boundary. This does NOT set
+ *     the `vtable` pointer in the context.
+ *
+ * Context structures can be discarded without any explicit deallocation.
+ * Hash function implementations are purely software and don't reserve
+ * any resources outside of the context structure itself.
+ *
+ *
+ * ## Object-Oriented API
+ *
+ * For each hash function that follows the procedural API described
+ * above, an object-oriented API is also provided. In that API, function
+ * pointers from the vtable (`br_xxx_vtable`) are used. The vtable
+ * incarnates object-oriented programming. An introduction on the OOP
+ * concept used here can be read on the BearSSL Web site:<br />
+ * &nbsp;&nbsp;&nbsp;[https://www.bearssl.org/oop.html](https://www.bearssl.org/oop.html)
+ *
+ * The vtable offers functions called `init()`, `update()`, `out()`,
+ * `set()` and `set_state()`, which are in fact the functions from
+ * the procedural API. That vtable also contains two informative fields:
+ *
+ *   - `context_size`
+ *
+ *     The size of the context structure (`br_xxx_context`), in bytes.
+ *     This can be used by generic implementations to perform dynamic
+ *     context allocation.
+ *
+ *   - `desc`
+ *
+ *     A "descriptor" field that encodes some information on the hash
+ *     function: symbolic identifier, output size, state size,
+ *     internal block size, details on the padding.
+ *
+ * Users of this object-oriented API (in particular generic HMAC
+ * implementations) may make the following assumptions:
+ *
+ *   - Hash output size is no more than 64 bytes.
+ *   - Hash internal state size is no more than 64 bytes.
+ *   - Internal block size is a power of two, no less than 16 and no more
+ *     than 256.
+ *
+ *
+ * ## Implemented Hash Functions
+ *
+ * Implemented hash functions are:
+ *
+ * | Function  | Name    | Output length | State length |
+ * | :-------- | :------ | :-----------: | :----------: |
+ * | MD5       | md5     |     16        |     16       |
+ * | SHA-1     | sha1    |     20        |     20       |
+ * | SHA-224   | sha224  |     28        |     32       |
+ * | SHA-256   | sha256  |     32        |     32       |
+ * | SHA-384   | sha384  |     48        |     64       |
+ * | SHA-512   | sha512  |     64        |     64       |
+ * | MD5+SHA-1 | md5sha1 |     36        |     36       |
+ *
+ * (MD5+SHA-1 is the concatenation of MD5 and SHA-1 computed over the
+ * same input; in the implementation, the internal data buffer is
+ * shared, thus making it more memory-efficient than separate MD5 and
+ * SHA-1. It can be useful in implementing SSL 3.0, TLS 1.0 and TLS
+ * 1.1.)
+ *
+ *
+ * ## Multi-Hasher
+ *
+ * An aggregate hasher is provided, that can compute several standard
+ * hash functions in parallel. It uses `br_multihash_context` and a
+ * procedural API. It is configured with the implementations (the vtables)
+ * that it should use; it will then compute all these hash functions in
+ * parallel, on the same input. It is meant to be used in cases when the
+ * hash of an object will be used, but the exact hash function is not
+ * known yet (typically, streamed processing on X.509 certificates).
+ *
+ * Only the standard hash functions (MD5, SHA-1, SHA-224, SHA-256, SHA-384
+ * and SHA-512) are supported by the multi-hasher.
+ *
+ *
+ * ## GHASH
+ *
+ * GHASH is not a generic hash function; it is a _universal_ hash function,
+ * which, as the name does not say, means that it CANNOT be used in most
+ * places where a hash function is needed. GHASH is used within the GCM
+ * encryption mode, to provide the checked integrity functionality.
+ *
+ * A GHASH implementation is basically a function that uses the type defined
+ * in this file under the name `br_ghash`:
+ *
+ *     typedef void (*br_ghash)(void *y, const void *h, const void *data, size_t len);
+ *
+ * The `y` pointer refers to a 16-byte value which is used as input, and
+ * receives the output of the GHASH invocation. `h` is a 16-byte secret
+ * value (that serves as key). `data` and `len` define the input data.
+ *
+ * Three GHASH implementations are provided, all constant-time, based on
+ * the use of integer multiplications with appropriate masking to cancel
+ * carry propagation.
+ */
+
+/**
+ * \brief Class type for hash function implementations.
+ *
+ * A `br_hash_class` instance references the methods implementing a hash
+ * function. Constant instances of this structure are defined for each
+ * implemented hash function. Such instances are also called "vtables".
+ *
+ * Vtables are used to support object-oriented programming, as
+ * described on [the BearSSL Web site](https://www.bearssl.org/oop.html).

+ *
+ * # Key Derivation Functions
+ *
+ * KDF are functions that takes a variable length input, and provide a
+ * variable length output, meant to be used to derive subkeys from a
+ * master key.
+ *
+ * ## HKDF
+ *
+ * HKDF is a KDF defined by [RFC 5869](https://tools.ietf.org/html/rfc5869).
+ * It is based on HMAC, itself using an underlying hash function. Any
+ * hash function can be used, as long as it is compatible with the rules
+ * for the HMAC implementation (i.e. output size is 64 bytes or less, hash
+ * internal state size is 64 bytes or less, and the internal block length is
+ * a power of 2 between 16 and 256 bytes). HKDF has two phases:
+ *
+ *  - HKDF-Extract: the input data in ingested, along with a "salt" value.
+ *
+ *  - HKDF-Expand: the output is produced, from the result of processing
+ *    the input and salt, and using an extra non-secret parameter called
+ *    "info".
+ *
+ * The "salt" and "info" strings are non-secret and can be empty. Their role
+ * is normally to bind the input and output, respectively, to conventional
+ * identifiers that qualifu them within the used protocol or application.
+ *
+ * The implementation defined in this file uses the following functions:
+ *
+ *  - `br_hkdf_init()`: initialize an HKDF context, with a hash function,
+ *    and the salt. This starts the HKDF-Extract process.
+ *
+ *  - `br_hkdf_inject()`: inject more input bytes. This function may be
+ *    called repeatedly if the input data is provided by chunks.
+ *
+ *  - `br_hkdf_flip()`: end the HKDF-Extract process, and start the
+ *    HKDF-Expand process.
+ *
+ *  - `br_hkdf_produce()`: get the next bytes of output. This function
+ *    may be called several times to obtain the full output by chunks.
+ *    For correct HKDF processing, the same "info" string must be
+ *    provided for each call.
+ *
+ * Note that the HKDF total output size (the number of bytes that
+ * HKDF-Expand is willing to produce) is limited: if the hash output size
+ * is _n_ bytes, then the maximum output size is _255*n_.
+ *
+ * ## SHAKE
+ *
+ * SHAKE is defined in
+ * [FIPS 202](https://csrc.nist.gov/publications/detail/fips/202/final)
+ * under two versions: SHAKE128 and SHAKE256, offering an alleged
+ * "security level" of 128 and 256 bits, respectively (SHAKE128 is
+ * about 20 to 25% faster than SHAKE256). SHAKE internally relies on
+ * the Keccak family of sponge functions, not on any externally provided
+ * hash function. Contrary to HKDF, SHAKE does not have a concept of
+ * either a "salt" or an "info" string. The API consists in four
+ * functions:
+ *
+ *  - `br_shake_init()`: initialize a SHAKE context for a given
+ *    security level.
+ *
+ *  - `br_shake_inject()`: inject more input bytes. This function may be
+ *    called repeatedly if the input data is provided by chunks.
+ *
+ *  - `br_shake_flip()`: end the data injection process, and start the
+ *    data production process.
+ *
+ *  - `br_shake_produce()`: get the next bytes of output. This function
+ *    may be called several times to obtain the full output by chunks.

+ * # PEM Support
+ *
+ * PEM is a traditional encoding layer use to store binary objects (in
+ * particular X.509 certificates, and private keys) in text files. While
+ * the acronym comes from an old, defunct standard ("Privacy Enhanced
+ * Mail"), the format has been reused, with some variations, by many
+ * systems, and is a _de facto_ standard, even though it is not, actually,
+ * specified in all clarity anywhere.
+ *
+ * ## Format Details
+ *
+ * BearSSL contains a generic, streamed PEM decoder, which handles the
+ * following format:
+ *
+ *   - The input source (a sequence of bytes) is assumed to be the
+ *     encoding of a text file in an ASCII-compatible charset. This
+ *     includes ISO-8859-1, Windows-1252, and UTF-8 encodings. Each
+ *     line ends on a newline character (U+000A LINE FEED). The
+ *     U+000D CARRIAGE RETURN characters are ignored, so the code
+ *     accepts both Windows-style and Unix-style line endings.
+ *
+ *   - Each object begins with a banner that occurs at the start of
+ *     a line; the first banner characters are "`-----BEGIN `" (five
+ *     dashes, the word "BEGIN", and a space). The banner matching is
+ *     not case-sensitive.
+ *
+ *   - The _object name_ consists in the characters that follow the
+ *     banner start sequence, up to the end of the line, but without
+ *     trailing dashes (in "normal" PEM, there are five trailing
+ *     dashes, but this implementation is not picky about these dashes).
+ *     The BearSSL decoder normalises the name characters to uppercase
+ *     (for ASCII letters only) and accepts names up to 127 characters.
+ *
+ *   - The object ends with a banner that again occurs at the start of
+ *     a line, and starts with "`-----END `" (again case-insensitive).
+ *
+ *   - Between that start and end banner, only Base64 data shall occur.
+ *     Base64 converts each sequence of three bytes into four
+ *     characters; the four characters are ASCII letters, digits, "`+`"
+ *     or "`-`" signs, and one or two "`=`" signs may occur in the last
+ *     quartet. Whitespace is ignored (whitespace is any ASCII character
+ *     of code 32 or less, so control characters are whitespace) and
+ *     lines may have arbitrary length; the only restriction is that the
+ *     four characters of a quartet must appear on the same line (no
+ *     line break inside a quartet).
+ *
+ *   - A single file may contain more than one PEM object. Bytes that
+ *     occur between objects are ignored.
+ *
+ *
+ * ## PEM Decoder API
+ *
+ * The PEM decoder offers a state-machine API. The caller allocates a
+ * decoder context, then injects source bytes. Source bytes are pushed
+ * with `br_pem_decoder_push()`. The decoder stops accepting bytes when
+ * it reaches an "event", which is either the start of an object, the
+ * end of an object, or a decoding error within an object.
+ *
+ * The `br_pem_decoder_event()` function is used to obtain the current
+ * event; it also clears it, thus allowing the decoder to accept more
+ * bytes. When a object start event is raised, the decoder context
+ * offers the found object name (normalised to ASCII uppercase).
+ *
+ * When an object is reached, the caller must set an appropriate callback
+ * function, which will receive (by chunks) the decoded object data.
+ *
+ * Since the decoder context makes no dynamic allocation, it requires
+ * no explicit deallocation.

+ *
+ * # Pseudo-Random Generators
+ *
+ * A PRNG is a state-based engine that outputs pseudo-random bytes on
+ * demand. It is initialized with an initial seed, and additional seed
+ * bytes can be added afterwards. Bytes produced depend on the seeds and
+ * also on the exact sequence of calls (including sizes requested for
+ * each call).
+ *
+ *
+ * ## Procedural and OOP API
+ *
+ * For the PRNG of name "`xxx`", two API are provided. The _procedural_
+ * API defined a context structure `br_xxx_context` and three functions:
+ *
+ *   - `br_xxx_init()`
+ *
+ *     Initialise the context with an initial seed.
+ *
+ *   - `br_xxx_generate()`
+ *
+ *     Produce some pseudo-random bytes.
+ *
+ *   - `br_xxx_update()`
+ *
+ *     Inject some additional seed.
+ *
+ * The initialisation function sets the first context field (`vtable`)
+ * to a pointer to the vtable that supports the OOP API. The OOP API
+ * provides access to the same functions through function pointers,
+ * named `init()`, `generate()` and `update()`.
+ *
+ * Note that the context initialisation method may accept additional
+ * parameters, provided as a 'const void *' pointer at API level. These
+ * additional parameters depend on the implemented PRNG.
+ *
+ *
+ * ## HMAC_DRBG
+ *
+ * HMAC_DRBG is defined in [NIST SP 800-90A Revision
+ * 1](http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-90Ar1.pdf).
+ * It uses HMAC repeatedly, over some configurable underlying hash
+ * function. In BearSSL, it is implemented under the "`hmac_drbg`" name.
+ * The "extra parameters" pointer for context initialisation should be
+ * set to a pointer to the vtable for the underlying hash function (e.g.
+ * pointer to `br_sha256_vtable` to use HMAC_DRBG with SHA-256).
+ *
+ * According to the NIST standard, each request shall produce up to
+ * 2<sup>19</sup> bits (i.e. 64 kB of data); moreover, the context shall
+ * be reseeded at least once every 2<sup>48</sup> requests. This
+ * implementation does not maintain the reseed counter (the threshold is
+ * too high to be reached in practice) and does not object to producing
+ * more than 64 kB in a single request; thus, the code cannot fail,
+ * which corresponds to the fact that the API has no room for error
+ * codes. However, this implies that requesting more than 64 kB in one
+ * `generate()` request, or making more than 2<sup>48</sup> requests
+ * without reseeding, is formally out of NIST specification. There is
+ * no currently known security penalty for exceeding the NIST limits,
+ * and, in any case, HMAC_DRBG usage in implementing SSL/TLS always
+ * stays much below these thresholds.
+ *
+ *
+ * ## AESCTR_DRBG
+ *
+ * AESCTR_DRBG is a custom PRNG based on AES-128 in CTR mode. This is
+ * meant to be used only in situations where you are desperate for
+ * speed, and have an hardware-optimized AES/CTR implementation. Whether
+ * this will yield perceptible improvements depends on what you use the
+ * pseudorandom bytes for, and how many you want; for instance, RSA key
+ * pair generation uses a substantial amount of randomness, and using
+ * AESCTR_DRBG instead of HMAC_DRBG yields a 15 to 20% increase in key
+ * generation speed on a recent x86 CPU (Intel Core i7-6567U at 3.30 GHz).
+ *
+ * Internally, it uses CTR mode with successive counter values, starting
+ * at zero (counter value expressed over 128 bits, big-endian convention).
+ * The counter is not allowed to reach 32768; thus, every 32768*16 bytes
+ * at most, the `update()` function is run (on an empty seed, if none is
+ * provided). The `update()` function computes the new AES-128 key by
+ * applying a custom hash function to the concatenation of a state-dependent
+ * word (encryption of an all-one block with the current key) and the new
+ * seed. The custom hash function uses Hirose's construction over AES-256;
+ * see the comments in `aesctr_drbg.c` for details.
+ *
+ * This DRBG does not follow an existing standard, and thus should be
+ * considered as inadequate for production use until it has been properly
+ * analysed.

+ *
+ * # RSA
+ *
+ * This file documents the RSA implementations provided with BearSSL.
+ * Note that the SSL engine accesses these implementations through a
+ * configurable API, so it is possible to, for instance, run a SSL
+ * server which uses a RSA engine which is not based on this code.
+ *
+ * ## Key Elements
+ *
+ * RSA public and private keys consist in lists of big integers. All
+ * such integers are represented with big-endian unsigned notation:
+ * first byte is the most significant, and the value is positive (so
+ * there is no dedicated "sign bit"). Public and private key structures
+ * thus contain, for each such integer, a pointer to the first value byte
+ * (`unsigned char *`), and a length (`size_t`) which is the number of
+ * relevant bytes. As a general rule, minimal-length encoding is not
+ * enforced: values may have extra leading bytes of value 0.
+ *
+ * RSA public keys consist in two integers:
+ *
+ *   - the modulus (`n`);
+ *   - the public exponent (`e`).
+ *
+ * RSA private keys, as defined in
+ * [PKCS#1](https://tools.ietf.org/html/rfc3447), contain eight integers:
+ *
+ *   - the modulus (`n`);
+ *   - the public exponent (`e`);
+ *   - the private exponent (`d`);
+ *   - the first prime factor (`p`);
+ *   - the second prime factor (`q`);
+ *   - the first reduced exponent (`dp`, which is `d` modulo `p-1`);
+ *   - the second reduced exponent (`dq`, which is `d` modulo `q-1`);
+ *   - the CRT coefficient (`iq`, the inverse of `q` modulo `p`).
+ *
+ * However, the implementations defined in BearSSL use only five of
+ * these integers: `p`, `q`, `dp`, `dq` and `iq`.
+ *
+ * ## Security Features and Limitations
+ *
+ * The implementations contained in BearSSL have the following limitations
+ * and features:
+ *
+ *   - They are constant-time. This means that the execution time and
+ *     memory access pattern may depend on the _lengths_ of the private
+ *     key components, but not on their value, nor on the value of
+ *     the operand. Note that this property is not achieved through
+ *     random masking, but "true" constant-time code.
+ *
+ *   - They support only private keys with two prime factors. RSA private
+ *     keys with three or more prime factors are nominally supported, but
+ *     rarely used; they may offer faster operations, at the expense of
+ *     more code and potentially a reduction in security if there are
+ *     "too many" prime factors.
+ *
+ *   - The public exponent may have arbitrary length. Of course, it is
+ *     a good idea to keep public exponents small, so that public key
+ *     operations are fast; but, contrary to some widely deployed
+ *     implementations, BearSSL has no problem with public exponents
+ *     longer than 32 bits.
+ *
+ *   - The two prime factors of the modulus need not have the same length
+ *     (but severely imbalanced factor lengths might reduce security).
+ *     Similarly, there is no requirement that the first factor (`p`)
+ *     be greater than the second factor (`q`).
+ *
+ *   - Prime factors and modulus must be smaller than a compile-time limit.
+ *     This is made necessary by the use of fixed-size stack buffers, and
+ *     the limit has been adjusted to keep stack usage under 2 kB for the
+ *     RSA operations. Currently, the maximum modulus size is 4096 bits,
+ *     and the maximum prime factor size is 2080 bits.
+ *
+ *   - The RSA functions themselves do not enforce lower size limits,
+ *     except that which is absolutely necessary for the operation to
+ *     mathematically make sense (e.g. a PKCS#1 v1.5 signature with
+ *     SHA-1 requires a modulus of at least 361 bits). It is up to users
+ *     of this code to enforce size limitations when appropriate (e.g.
+ *     the X.509 validation engine, by default, rejects RSA keys of
+ *     less than 1017 bits).
+ *
+ *   - Within the size constraints expressed above, arbitrary bit lengths
+ *     are supported. There is no requirement that prime factors or
+ *     modulus have a size multiple of 8 or 16.
+ *
+ *   - When verifying PKCS#1 v1.5 signatures, both variants of the hash
+ *     function identifying header (with and without the ASN.1 NULL) are
+ *     supported. When producing such signatures, the variant with the
+ *     ASN.1 NULL is used.
+ *
+ * ## Implementations
+ *
+ * Three RSA implementations are included:
+ *
+ *   - The **i32** implementation internally represents big integers
+ *     as arrays of 32-bit integers. It is perfunctory and portable,
+ *     but not very efficient.
+ *
+ *   - The **i31** implementation uses 32-bit integers, each containing
+ *     31 bits worth of integer data. The i31 implementation is somewhat
+ *     faster than the i32 implementation (the reduced integer size makes
+ *     carry propagation easier) for a similar code footprint, but uses
+ *     very slightly larger stack buffers (about 4% bigger).
+ *
+ *   - The **i62** implementation is similar to the i31 implementation,
+ *     except that it internally leverages the 64x64->128 multiplication
+ *     opcode. This implementation is available only on architectures
+ *     where such an opcode exists. It is much faster than i31.
+ *
+ *   - The **i15** implementation uses 16-bit integers, each containing
+ *     15 bits worth of integer data. Multiplication results fit on
+ *     32 bits, so this won't use the "widening" multiplication routine
+ *     on ARM Cortex M0/M0+, for much better performance and constant-time
+ *     execution.

+ * For all private keys produced by the key generator functions

+ *
+ * The encoded private exponent is written in `d` (unsigned big-endian
+ * convention), and the length (in bytes) is returned. If `d` is `NULL`,
+ * then the exponent is not written anywhere, but the length is still
+ * returned. On error, 0 is returned.
+ *
+ * Not all error conditions are detected when `d` is `NULL`; therefore, the
+ * returned value shall be checked also when actually producing the value.

+ *
+ *   - The `len` parameter is never zero, and is always lower than 20000.

+ *   - The number of processed bytes (read or written) is returned. Since
+ *     that number is less than 20000, it always fits on an `int`.
+ *
+ *   - On error, the callbacks return -1. Reaching end-of-stream is an

+ *     time until at least one byte can be sent or received (if a
+ *     callback returns 0, then the wrapper invokes it again

+ *
+ *   - Callbacks MAY return as soon as at least one byte is processed;
+ *     they MAY also insist on reading or writing _all_ requested bytes.
+ *     Since SSL is a self-terminated protocol (each record has a length

+ *
+ * # X.509 Certificate Chain Processing
+ *
+ * An X.509 processing engine receives an X.509 chain, chunk by chunk,
+ * as received from a SSL/TLS client or server (the client receives the
+ * server's certificate chain, and the server receives the client's
+ * certificate chain if it requested a client certificate). The chain
+ * is thus injected in the engine in SSL order (end-entity first).
+ *
+ * The engine's job is to return the public key to use for SSL/TLS.
+ * How exactly that key is obtained and verified is entirely up to the
+ * engine.
+ *
+ * **The "known key" engine** returns a public key which is already known
+ * from out-of-band information (e.g. the client _remembers_ the key from
+ * a previous connection, as in the usual SSH model). This is the simplest
+ * engine since it simply ignores the chain, thereby avoiding the need
+ * for any decoding logic.
+ *
+ * **The "minimal" engine** implements minimal X.509 decoding and chain
+ * validation:
+ *
+ *   - The provided chain should validate "as is". There is no attempt
+ *     at reordering, skipping or downloading extra certificates.
+ *
+ *   - X.509 v1, v2 and v3 certificates are supported.
+ *
+ *   - Trust anchors are a DN and a public key. Each anchor is either a
+ *     "CA" anchor, or a non-CA.
+ *
+ *   - If the end-entity certificate matches a non-CA anchor (subject DN
+ *     is equal to the non-CA name, and public key is also identical to
+ *     the anchor key), then this is a _direct trust_ case and the
+ *     remaining certificates are ignored.
+ *
+ *   - Unless direct trust is applied, the chain must be verifiable up to
+ *     a certificate whose issuer DN matches the DN from a "CA" trust anchor,
+ *     and whose signature is verifiable against that anchor's public key.
+ *     Subsequent certificates in the chain are ignored.
+ *
+ *   - The engine verifies subject/issuer DN matching, and enforces
+ *     processing of Basic Constraints and Key Usage extensions. The
+ *     Authority Key Identifier, Subject Key Identifier, Issuer Alt Name,
+ *     Subject Directory Attribute, CRL Distribution Points, Freshest CRL,
+ *     Authority Info Access and Subject Info Access extensions are
+ *     ignored. The Subject Alt Name is decoded for the end-entity
+ *     certificate under some conditions (see below). Other extensions
+ *     are ignored if non-critical, or imply chain rejection if critical.
+ *
+ *   - The Subject Alt Name extension is parsed for names of type `dNSName`
+ *     when decoding the end-entity certificate, and only if there is a
+ *     server name to match. If there is no SAN extension, then the
+ *     Common Name from the subjectDN is used. That name matching is
+ *     case-insensitive and honours a single starting wildcard (i.e. if
+ *     the name in the certificate starts with "`*.`" then this matches
+ *     any word as first element). Note: this name matching is performed
+ *     also in the "direct trust" model.
+ *
+ *   - DN matching is byte-to-byte equality (a future version might
+ *     include some limited processing for case-insensitive matching and
+ *     whitespace normalisation).
+ *
+ *   - Successful validation produces a public key type but also a set
+ *     of allowed usages (`BR_KEYTYPE_KEYX` and/or `BR_KEYTYPE_SIGN`).
+ *     The caller is responsible for checking that the key type and
+ *     usages are compatible with the expected values (e.g. with the
+ *     selected cipher suite, when the client validates the server's
+ *     certificate).
+ *
+ * **Important caveats:**
+ *
+ *   - The "minimal" engine does not check revocation status. The relevant
+ *     extensions are ignored, and CRL or OCSP responses are not gathered
+ *     or checked.
+ *
+ *   - The "minimal" engine does not currently support Name Constraints
+ *     (some basic functionality to handle sub-domains may be added in a
+ *     later version).
+ *
+ *   - The decoder is not "validating" in the sense that it won't reject
+ *     some certificates with invalid field values when these fields are
+ *     not actually processed.

+This directory contains sample code for using BearSSL.
+
+client_basic.c
+
+   A sample client code, that connects to a server, performs a SSL
+   handshake, sends a basic HTTP GET request, and dumps the complete
+   answer on stdout.
+
+   Compile it against BearSSL headers (in the ../inc directory) and
+   library (libbearssl.a). This code will validate the server
+   certificate against two hardcoded trust anchors.
+
+server_basic.c
+
+   A sample SSL server, that serves one client at a time. It reads a
+   single HTTP request (that it does not really parse; it just waits for
+   the two successive line endings that mark the end of the request),
+   and pushes a basic response.
+
+   Compile it against BearSSL headers (in the ../inc directory) and
+   library (libbearssl.a). Depending on compilation options (see the
+   code), it will use one of several certificate chains, that exercise
+   various combinations of RSA and EC keys and signatures. These
+   certificate chains link to the trust anchors that are hardcoded
+   in client_basic.c, so the sample client and the sample server can
+   be tested against each other.
+
+custom_profile.c
+
+   A sample C source file that shows how to write your own client or
+   server profiles (selections of cipher suites and algorithms).
+
+
+The .pem files are certificate and keys corresponding to the chains
+and anchors used by the sample client and server. They are provided
+for reference only; these files are not used by the examples.

+ * Implementation Notes
+ * ====================
+ *
+ * The combined CTR + CBC-MAC functions can only handle full blocks,
+ * so some buffering is necessary. Moreover, EAX has a special padding
+ * rule for CBC-MAC, which implies that we cannot compute the MAC over
+ * the last received full block until we know whether we are at the
+ * end of the data or not.
+ *
+ *  - 'ptr' contains a value from 1 to 16, which is the number of bytes
+ *    accumulated in buf[] that still needs to be processed with the
+ *    current OMAC computation. Beware that this can go to 16: a
+ *    complete block cannot be processed until it is known whether it
+ *    is the last block or not. However, it can never be 0, because
+ *    OMAC^t works on an input that is at least one-block long.
+ *
+ *  - When processing the message itself, CTR encryption/decryption is
+ *    also done at the same time. The first 'ptr' bytes of buf[] then
+ *    contains the encrypted bytes, while the last '16 - ptr' bytes of
+ *    buf[] are the remnants of the stream block, to be used against
+ *    the next input bytes, when available.
+ *
+ *  - The current counter and running CBC-MAC values are kept in 'ctr'
+ *    and 'cbcmac', respectively.
+ *
+ *  - The derived keys for padding are kept in L2 and L4 (double and
+ *    quadruple of Enc_K(0^n), in GF(2^128), respectively).

+ * Implementation Notes
+ * ====================
+ *
+ * Since CTR and GHASH implementations can handle only full blocks, a
+ * 16-byte buffer (buf[]) is maintained in the context:
+ *
+ *  - When processing AAD, buf[] contains the 0-15 unprocessed bytes.
+ *
+ *  - When doing CTR encryption / decryption, buf[] contains the AES output
+ *    for the last partial block, to be used with the next few bytes of
+ *    data, as well as the already encrypted bytes. For instance, if the
+ *    processed data length so far is 21 bytes, then buf[0..4] contains
+ *    the five last encrypted bytes, and buf[5..15] contains the next 11
+ *    AES output bytes to be XORed with the next 11 bytes of input.
+ *
+ *    The recorded AES output bytes are used to complete the block when
+ *    the corresponding bytes are obtained. Note that buf[] always
+ *    contains the _encrypted_ bytes, whether we apply encryption or
+ *    decryption: these bytes are used as input to GHASH when the block
+ *    is complete.
+ *
+ * In both cases, the low bits of the data length counters (count_aad,
+ * count_ctr) are used to work out the current situation.

+	 * we have z1, z2, z3, and z4, and want to invert all of them,
+	 * we compute u = 1/(z1*z2*z3*z4), and then we have:
+	 *   1/z1 = u*z2*z3*z4
+	 *   1/z2 = u*z1*z3*z4
+	 *   1/z3 = u*z1*z2*z4
+	 *   1/z4 = u*z1*z2*z3
+	 *
+	 * The partial products are computed recursively:
+	 *
+	 *  - on input (z_1,z_2), return (z_2,z_1) and z_1*z_2
+	 *  - on input (z_1,z_2,... z_n):
+	 *       recurse on (z_1,z_2,... z_(n/2)) -> r1 and m1
+	 *       recurse on (z_(n/2+1),z_(n/2+2)... z_n) -> r2 and m2
+	 *       multiply elements of r1 by m2 -> s1
+	 *       multiply elements of r2 by m1 -> s2
+	 *       return r1||r2 and m1*m2
+	 *
+	 * In the example below, we suppose that we have 14 elements.
+	 * Let z1, z2,... zE be the 14 values to invert (index noted in
+	 * hexadecimal, starting at 1).

+ * GHASH is defined over elements of GF(2^128) with "full little-endian"
+ * representation: leftmost byte is least significant, and, within each
+ * byte, leftmost _bit_ is least significant. The natural ordering in
+ * x86 is "mixed little-endian": bytes are ordered from least to most
+ * significant, but bits within a byte are in most-to-least significant
+ * order. Going to full little-endian representation would require
+ * reversing bits within each byte, which is doable but expensive.
+ *
+ * Instead, we go to full big-endian representation, by swapping bytes
+ * around, which is done with a single _mm_shuffle_epi8() opcode (it
+ * comes with SSSE3; all CPU that offer pclmulqdq also have SSSE3). We
+ * can use a full big-endian representation because in a carryless
+ * multiplication, we have a nice bit reversal property:
+ *
+ *    rev_128(x) * rev_128(y) = rev_255(x * y)
+ *
+ * So by using full big-endian, we still get the right result, except
+ * that it is right-shifted by 1 bit. The left-shift is relatively
+ * inexpensive, and it can be mutualised.
+ *
+ *
+ * Since SSE2 opcodes do not have facilities for shitfting full 128-bit

+ * chunks. We number chunks from 0 to 3 in left to right order.

+	 *   a = y
+	 *   b = m
+	 *   u = x
+	 *   v = 0
+	 *
+	 * The formal definition of the algorithm is a sequence of steps:

+	 *   - If a is even, then a <- a/2 and u <- u/2 mod m.
+	 *   - Otherwise, if b is even, then b <- b/2 and v <- v/2 mod m.

+	 *   - Otherwise, b <- (b-a)/2 and v <- (v-u)/2 mod m.
+	 *
+	 * Algorithm stops when a = b. At that point, they both are equal
+	 * to GCD(y,m); the modular division succeeds if that value is 1.
+	 * The result of the modular division is then u (or v: both are
+	 * equal at that point).
+	 *
+	 * Each step makes either a or b shrink by at least one bit; hence,
+	 * if m has bit length k bits, then 2k-2 steps are sufficient.
+	 *
+	 *
+	 * Though complexity is quadratic in the size of m, the bit-by-bit
+	 * processing is not very efficient. We can speed up processing by
+	 * remarking that the decisions are taken based only on observation
+	 * of the top and low bits of a and b.
+	 *
+	 * In the loop below, at each iteration, we use the two top words
+	 * of a and b, and the low words of a and b, to compute reduction
+	 * parameters pa, pb, qa and qb such that the new values for a
+	 * and b are:
+	 *
+	 *   a' = (a*pa + b*pb) / (2^15)
+	 *   b' = (a*qa + b*qb) / (2^15)
+	 *
+	 * the division being exact.
+	 *
+	 * Since the choices are based on the top words, they may be slightly
+	 * off, requiring an optional correction: if a' < 0, then we replace
+	 * pa with -pa, and pb with -pb. The total length of a and b is
+	 * thus reduced by at least 14 bits at each iteration.
+	 *

+	 * remarking that the decisions are taken based only on observation
+	 * of the top and low bits of a and b.

+	 * The stopping conditions are still the same, though: when a

+	 *
+	 * Instead, we first use one step of the extended GCD:

+	 *     enforce non-ridiculously-small factors.

+	 *     binary GCD; we can arrange for u < r and v < e, i.e. all
+	 *     values fit on 32 bits).

+	 *   a = e    u0 = 1   v0 = 0
+	 *   b = r    u1 = r   v1 = e-1
+	 * The following invariants are maintained:
+	 *   a = u0*e - v0*r
+	 *   b = u1*e - v1*r
+	 *   0 < a <= e
+	 *   0 < b <= r
+	 *   0 <= u0 <= r
+	 *   0 <= v0 <= e
+	 *   0 <= u1 <= r
+	 *   0 <= v1 <= e
+	 *
+	 * At each iteration, we reduce either a or b by one bit, and
+	 * adjust u0, u1, v0 and v1 to maintain the invariants:
+	 *  - if a is even, then a <- a/2
+	 *  - otherwise, if b is even, then b <- b/2
+	 *  - otherwise, if a > b, then a <- (a-b)/2
+	 *  - otherwise, if b > a, then b <- (b-a)/2
+	 * Algorithm stops when a = b. At that point, the common value
+	 * is the GCD of e and r; it must be 1 (otherwise, the private
+	 * key or public exponent is not valid). The (u0,v0) or (u1,v1)
+	 * pairs are the solution we are looking for.
+	 *
+	 * Since either a or b is reduced by at least 1 bit at each
+	 * iteration, 62 iterations are enough to reach the end
+	 * condition.
+	 *
+	 * To maintain the invariants, we must compute the same operations
+	 * on the u* and v* values that we do on a and b:
+	 *  - When a is divided by 2, u0 and v0 must be divided by 2.
+	 *  - When b is divided by 2, u1 and v1 must be divided by 2.
+	 *  - When b is subtracted from a, u1 and v1 are subtracted from
+	 *    u0 and v0, respectively.
+	 *  - When a is subtracted from b, u0 and v0 are subtracted from
+	 *    u1 and v1, respectively.
+	 *
+	 * However, we want to keep the u* and v* values in their proper
+	 * ranges. The following remarks apply:
+	 *
+	 *  - When a is divided by 2, then a is even. Therefore:
+	 *
+	 *     * If r is odd, then u0 and v0 must have the same parity;
+	 *       if they are both odd, then adding r to u0 and e to v0
+	 *       makes them both even, and the division by 2 brings them
+	 *       back to the proper range.
+	 *
+	 *     * If r is even, then u0 must be even; if v0 is odd, then
+	 *       adding r to u0 and e to v0 makes them both even, and the
+	 *       division by 2 brings them back to the proper range.
+	 *
+	 *    Thus, all we need to do is to look at the parity of v0,
+	 *    and add (r,e) to (u0,v0) when v0 is odd. In order to avoid
+	 *    a 32-bit overflow, we can add ((r+1)/2,(e/2)+1) after the
+	 *    division (r+1 does not overflow since r < e; and (e/2)+1
+	 *    is equal to (e+1)/2 since e is odd).
+	 *
+	 *  - When we subtract b from a, three cases may occur:
+	 *
+	 *     * u1 <= u0 and v1 <= v0: just do the subtractions
+	 *
+	 *     * u1 > u0 and v1 > v0: compute:
+	 *         (u0, v0) <- (u0 + r - u1, v0 + e - v1)
+	 *
+	 *     * u1 <= u0 and v1 > v0: compute:
+	 *         (u0, v0) <- (u0 + r - u1, v0 + e - v1)
+	 *
+	 *    The fourth case (u1 > u0 and v1 <= v0) is not possible
+	 *    because it would contradict "b < a" (which is the reason
+	 *    why we subtract b from a).
+	 *
+	 *    The tricky case is the third one: from the equations, it
+	 *    seems that u0 may go out of range. However, the invariants
+	 *    and ranges of other values imply that, in that case, the
+	 *    new u0 does not actually exceed the range.
+	 *
+	 *    We can thus handle the subtraction by adding (r,e) based
+	 *    solely on the comparison between v0 and v1.

+	 *   a = e    u0 = 1   v0 = 0
+	 *   b = r    u1 = r   v1 = e-1
+	 * The following invariants are maintained:

+	 *   0 < a <= e

+	 *   0 <= u0 <= r
+	 *   0 <= v0 <= e
+	 *   0 <= u1 <= r
+	 *   0 <= v1 <= e
+	 *
+	 * At each iteration, we reduce either a or b by one bit, and

+	 *  - if a is even, then a <- a/2
+	 *  - otherwise, if b is even, then b <- b/2
+	 *  - otherwise, if a > b, then a <- (a-b)/2
+	 *  - otherwise, if b > a, then b <- (b-a)/2
+	 * Algorithm stops when a = b. At that point, the common value
+	 * is the GCD of e and r; it must be 1 (otherwise, the private
+	 * key or public exponent is not valid). The (u0,v0) or (u1,v1)
+	 * pairs are the solution we are looking for.
+	 *
+	 * Since either a or b is reduced by at least 1 bit at each
+	 * iteration, 62 iterations are enough to reach the end
+	 * condition.
+	 *
+	 * To maintain the invariants, we must compute the same operations
+	 * on the u* and v* values that we do on a and b:
+	 *  - When a is divided by 2, u0 and v0 must be divided by 2.
+	 *  - When b is divided by 2, u1 and v1 must be divided by 2.
+	 *  - When b is subtracted from a, u1 and v1 are subtracted from
+	 *    u0 and v0, respectively.
+	 *  - When a is subtracted from b, u0 and v0 are subtracted from
+	 *    u1 and v1, respectively.
+	 *
+	 * However, we want to keep the u* and v* values in their proper
+	 * ranges. The following remarks apply:
+	 *
+	 *  - When a is divided by 2, then a is even. Therefore:
+	 *
+	 *     * If r is odd, then u0 and v0 must have the same parity;
+	 *       if they are both odd, then adding r to u0 and e to v0
+	 *       makes them both even, and the division by 2 brings them
+	 *       back to the proper range.
+	 *
+	 *     * If r is even, then u0 must be even; if v0 is odd, then
+	 *       adding r to u0 and e to v0 makes them both even, and the
+	 *       division by 2 brings them back to the proper range.
+	 *
+	 *    Thus, all we need to do is to look at the parity of v0,
+	 *    and add (r,e) to (u0,v0) when v0 is odd. In order to avoid
+	 *    a 32-bit overflow, we can add ((r+1)/2,(e/2)+1) after the
+	 *    division (r+1 does not overflow since r < e; and (e/2)+1
+	 *    is equal to (e+1)/2 since e is odd).
+	 *
+	 *  - When we subtract b from a, three cases may occur:
+	 *
+	 *     * u1 <= u0 and v1 <= v0: just do the subtractions
+	 *
+	 *     * u1 > u0 and v1 > v0: compute:
+	 *         (u0, v0) <- (u0 + r - u1, v0 + e - v1)
+	 *
+	 *     * u1 <= u0 and v1 > v0: compute:
+	 *         (u0, v0) <- (u0 + r - u1, v0 + e - v1)
+	 *
+	 *    The fourth case (u1 > u0 and v1 <= v0) is not possible
+	 *    because it would contradict "b < a" (which is the reason
+	 *    why we subtract b from a).
+	 *
+	 *    The tricky case is the third one: from the equations, it
+	 *    seems that u0 may go out of range. However, the invariants
+	 *    and ranges of other values imply that, in that case, the
+	 *    new u0 does not actually exceed the range.
+	 *
+	 *    We can thus handle the subtraction by adding (r,e) based
+	 *    solely on the comparison between v0 and v1.

+/* ==================================================================== */
+/*
+ * This part of the file does the low-level record management.
+ */
+
+/*
+ * IMPLEMENTATION NOTES
+ * ====================
+ *
+ * In this file, we designate by "input" (and the "i" letter) the "recv"
+ * operations: incoming records from the peer, from which payload data
+ * is obtained, and must be extracted by the application (or the SSL
+ * handshake engine). Similarly, "output" (and the "o" letter) is for
+ * "send": payload data injected by the application (and SSL handshake
+ * engine), to be wrapped into records, that are then conveyed to the
+ * peer over the transport medium.
+ *
+ * The input and output buffers may be distinct or shared. When
+ * shared, input and output cannot occur concurrently; the caller
+ * must make sure that it never needs to output data while input
+ * data has been received. In practice, a shared buffer prevents
+ * pipelining of HTTP requests, or similar protocols; however, a
+ * shared buffer saves RAM.
+ *
+ * The input buffer is pointed to by 'ibuf' and has size 'ibuf_len';
+ * the output buffer is pointed to by 'obuf' and has size 'obuf_len'.
+ * From the size of these buffers is derived the maximum fragment
+ * length, which will be honoured upon sending records; regardless of
+ * that length, incoming records will be processed as long as they
+ * fit in the input buffer, and their length still complies with the
+ * protocol specification (maximum plaintext payload length is 16384
+ * bytes).
+ *
+ * Three registers are used to manage buffering in ibuf, called ixa,
+ * ixb and ixc. Similarly, three registers are used to manage buffering
+ * in obuf, called oxa, oxb and oxc.
+ *
+ *
+ * At any time, the engine is in one of the following modes:
+ * -- Failed mode: an error occurs, no I/O can happen.
+ * -- Input mode: the engine can either receive record bytes from the
+ * transport layer, or it has some buffered payload bytes to yield.
+ * -- Output mode: the engine can either receive payload bytes, or it
+ * has some record bytes to send to the transport layer.
+ * -- Input/Output mode: both input and output modes are active. When
+ * the buffer is shared, this can happen only when the buffer is empty
+ * (no buffered payload bytes or record bytes in either direction).
+ *
+ *
+ * Failed mode:
+ * ------------
+ *
+ * I/O failed for some reason (invalid received data, not enough room
+ * for the next record...). No I/O may ever occur again for this context,
+ * until an explicit reset is performed. This mode, and the error code,
+ * are also used for protocol errors, especially handshake errors.
+ *
+ *
+ * Input mode:
+ * -----------
+ *
+ *  ixa   index within ibuf[] for the currently read data
+ *  ixb   maximum index within ibuf[] for the currently read data
+ *  ixc   number of bytes not yet received for the current record
+ * 
+ * -- When ixa == ixb, there is no available data for readers. When
+ * ixa != ixb, there is available data and it starts at offset ixa.
+ *
+ * -- When waiting for the next record header, ixa and ixb are equal
+ * and contain a value ranging from 0 to 4; ixc is equal to 5-ixa.
+ *
+ * -- When the header has been received, record data is obtained. The
+ * ixc field records how many bytes are still needed to reach the
+ * end of the current record.
+ *
+ *    ** If encryption is active, then ixa and ixb are kept equal, and
+ *    point to the end of the currently received record bytes. When
+ *    ixc reaches 0, decryption/MAC is applied, and ixa and ixb are
+ *    adjusted.
+ *
+ *    ** If encryption is not active, then ixa and ixb are distinct
+ *    and data can be read right away. Additional record data is
+ *    obtained only when ixa == ixb.
+ *
+ * Note: in input mode and no encryption, records larger than the buffer
+ * size are allowed. When encryption is active, the complete record must
+ * fit within the buffer, since it cannot be decrypted/MACed until it
+ * has been completely received.
+ *
+ * -- When receiving the next record header, 'version_in' contains the
+ * expected input version (0 if not expecting a specific version); on
+ * mismatch, the mode switches to 'failed'.
+ *
+ * -- When the header has been received, 'version_in' contains the received
+ * version. It is up to the caller to check and adjust the 'version_in' field
+ * to implement the required semantics.
+ *
+ * -- The 'record_type_in' field is updated with the incoming record type
+ * when the next record header has been received.
+ *
+ *
+ * Output mode:
+ * ------------
+ *
+ *  oxa   index within obuf[] for the currently accumulated data
+ *  oxb   maximum index within obuf[] for record data
+ *  oxc   pointer for start of record data, and for record sending
+ *
+ * -- When oxa != oxb, more data can be accumulated into the current
+ * record; when oxa == oxb, a closed record is being sent.
+ *
+ * -- When accumulating data, oxc points to the start of the data.
+ *
+ * -- During record sending, oxa (and oxb) point to the next record byte
+ * to send, and oxc indicates the end of the current record.
+ *
+ * Note: sent records must fit within the buffer, since the header is
+ * adjusted only when the complete record has been assembled.
+ *
+ * -- The 'version_out' and 'record_type_out' fields are used to build the
+ * record header when the mode is switched to 'sending'.
+ *
+ *
+ * Modes:
+ * ------
+ *
+ * The state register iomode contains one of the following values:
+ *
+ *  BR_IO_FAILED   I/O failed
+ *  BR_IO_IN       input mode
+ *  BR_IO_OUT      output mode
+ *  BR_IO_INOUT    input/output mode
+ *
+ * Whether encryption is active on incoming records is indicated by the
+ * incrypt flag. For outgoing records, there is no such flag; "encryption"
+ * is always considered active, but initially uses functions that do not
+ * encrypt anything. The 'incrypt' flag is needed because when there is
+ * no active encryption, records larger than the I/O buffer are accepted.
+ *
+ * Note: we do not support no-encryption modes (MAC only).
+ *
+ * TODO: implement GCM support
+ *
+ *
+ * Misc:
+ * -----
+ *
+ * 'max_frag_len' is the maximum plaintext size for an outgoing record.
+ * By default, it is set to the maximum value that fits in the provided
+ * buffers, in the following list: 512, 1024, 2048, 4096, 16384. The
+ * caller may change it if needed, but the new value MUST still fit in
+ * the buffers, and it MUST be one of the list above for compatibility
+ * with the Maximum Fragment Length extension.
+ *
+ * For incoming records, only the total buffer length and current
+ * encryption mode impact the maximum length for incoming records. The
+ * 'max_frag_len' value is still adjusted so that records up to that
+ * length can be both received and sent.
+ *
+ *
+ * Offsets and lengths:
+ * --------------------
+ *
+ * When sending fragments with TLS-1.1+, the maximum overhead is:
+ *   5 bytes for the record header
+ *   16 bytes for the explicit IV
+ *   48 bytes for the MAC (HMAC/SHA-384)
+ *   16 bytes for the padding (AES)
+ * so a total of 85 extra bytes. Note that we support block cipher sizes
+ * up to 16 bytes (AES) and HMAC output sizes up to 48 bytes (SHA-384).
+ *
+ * With TLS-1.0 and CBC mode, we apply a 1/n-1 split, for a maximum
+ * overhead of:
+ *   5 bytes for the first record header
+ *   32 bytes for the first record payload (AES-CBC + HMAC/SHA-1)
+ *   5 bytes for the second record header
+ *   20 bytes for the MAC (HMAC/SHA-1)
+ *   16 bytes for the padding (AES)
+ *   -1 byte to account for the payload byte in the first record
+ * so a total of 77 extra bytes at most, less than the 85 bytes above.
+ * Note that with TLS-1.0, the MAC is HMAC with either MD5 or SHA-1, but
+ * no other hash function.
+ *
+ * The implementation does not try to send larger records when the current
+ * encryption mode has less overhead.
+ *
+ * Maximum input record overhead is:
+ *   5 bytes for the record header
+ *   16 bytes for the explicit IV (TLS-1.1+)
+ *   48 bytes for the MAC (HMAC/SHA-384)
+ *   256 bytes for the padding
+ * so a total of 325 extra bytes.
+ *
+ * When receiving the next record header, it is written into the buffer
+ * bytes 0 to 4 (inclusive). Record data is always written into buf[]
+ * starting at offset 5. When encryption is active, the plaintext data
+ * may start at a larger offset (e.g. because of an explicit IV).

+ * IMPLEMENTATION NOTES
+ * ====================
+ *
+ * The handshake processor is written in T0 and runs as a coroutine.
+ * It receives the contents of all records except application data, and
+ * is responsible for producing the contents of all records except
+ * application data.
+ *
+ * A state flag is maintained, which specifies whether application data
+ * is acceptable or not. When it is set:
+ *
+ * -- Application data can be injected as payload data (provided that
+ *    the output buffer is ready for that).
+ *
+ * -- Incoming application data records are accepted, and yield data
+ *    that the caller may retrieve.
+ *
+ * When the flag is cleared, application data is not accepted from the
+ * application, and incoming application data records trigger an error.
+ *
+ *
+ * Records of type handshake, alert or change-cipher-spec are handled
+ * by the handshake processor. The handshake processor is written in T0
+ * and runs as a coroutine; it gets invoked whenever one of the following
+ * situations is reached:
+ *
+ * -- An incoming record has type handshake, alert or change-cipher-spec,
+ *    and yields data that can be read (zero-length records are thus
+ *    ignored).
+ *
+ * -- An outgoing record has just finished being sent, and the "application
+ *    data" flag is cleared.
+ *
+ * -- The caller wishes to perform a close (call to br_ssl_engine_close()).
+ *
+ * -- The caller wishes to perform a renegotiation (call to
+ *    br_ssl_engine_renegotiate()).
+ *
+ * Whenever the handshake processor is entered, access to the payload
+ * buffers is provided, along with some information about explicit
+ * closures or renegotiations.

+\ IMPLEMENTATION NOTES
+\ ====================
+\
+\ This code handles all records except application data records.
+\ Application data is accepted (incoming records, outgoing payload data)
+\ only when the application_data flag is set, which is done at the end
+\ of the handshake; and it is cleared whenever a renegotiation or a
+\ closure takes place.
+\
+\ Incoming alerts are processed on the fly; fatal alerts terminate the
+\ context, while warnings are ignored, except for close_notify, which
+\ triggers the closure procedure. That procedure never returns (it ends
+\ with an 'ERR_OK fail' call). We can thus make this processing right
+\ into the read functions.
+\
+\ Specific actions from the caller (closure or renegotiation) may happen
+\ only when jumping back into the T0 code, i.e. just after a 'co' call.
+\ Similarly, incoming record type may change only while the caller has
+\ control, so we need to check that type only when returning from a 'co'.
+\
+\ The handshake processor needs to defer back to the caller ('co') only
+\ in one of the following situations:
+\
+\ -- Some handshake data is expected.
+\
+\ -- The handshake is finished, and application data may flow. There may
+\    be some incoming handshake data (HelloRequest from the server). This
+\    is the only situation where a renegotiation call won't be ignored.
+\
+\ -- Some change-cipher-spec data is expected.
+\
+\ -- An alert record is expected. Other types of incoming records will be
+\    skipped.
+\
+\ -- Waiting for the currently accumulated record to be sent and the
+\    output buffer to become free again for another record.
+

+\ performed with a binary search (not implemented for the moment, since it
+\ does not appear to matter much in practice).

+ * Each entry consists in a fixed number of bytes. Entries are concatenated

+ * expressed over 32 bits (so the cache may have size at most 4 GB, which
+ * "ought to be enough for everyone"). The "null address" is 0xFFFFFFFF.
+ * Note that since the storage block alignment is in no way guaranteed, we
+ * perform only accesses that can handle unaligned data.
+ *
+ * Two concurrent data structures are maintained:
+ *
+ * -- Entries are organised in a doubly-linked list; saved entries are added
+ * at the head, and loaded entries are moved to the head. Eviction uses
+ * the list tail (this is the LRU algorithm).
+ *
+ * -- Entries are indexed with a binary tree: all left descendants of a
+ * node have a lower session ID (in lexicographic order), while all
+ * right descendants have a higher session ID. The tree is heuristically
+ * balanced.
+ *
+ * Entry format:
+ *
+ *   session ID          32 bytes
+ *   master secret       48 bytes
+ *   protocol version    2 bytes (big endian)
+ *   cipher suite        2 bytes (big endian)
+ *   list prev           4 bytes (big endian)
+ *   list next           4 bytes (big endian)
+ *   tree left child     4 bytes (big endian)
+ *   tree right child    4 bytes (big endian)
+ *
+ * If an entry has a protocol version set to 0, then it is "disabled":
+ * it was a session pushed to the cache at some point, but it has
+ * been explicitly removed.
+ *
+ * We need to keep the tree balanced because an attacker could make
+ * handshakes, selecting some specific sessions (by reusing them) to
+ * try to make us make an imbalanced tree that makes lookups expensive
+ * (a denial-of-service attack that would persist as long as the cache
+ * remains, i.e. even after the attacker made all his connections).
+ * To do that, we replace the session ID (or the start of the session ID)
+ * with a HMAC value computed over the replaced part; the hash function
+ * implementation and the key are obtained from the server context upon
+ * first save() call.
+ *
+ * Theoretically, an attacker could use the exact timing of the lookup
+ * to infer the current tree topology, and try to revive entries to make
+ * it as unbalanced as possible. However, since the session ID are
+ * chosen randomly by the server, and the attacker cannot see the
+ * indexing values and must thus rely on blind selection, it should be
+ * exponentially difficult for the attacker to maintain a large
+ * imbalance.

+ * The "accumulator" word is nominally a 130-bit value. We split it into
+ * words of 44 bits, each held in a 64-bit variable.
+ *
+ * If the current accumulator is a = a0 + a1*W + a2*W^2 (where W = 2^44)
+ * and r = r0 + r1*W + r2*W^2, then:
+ *
+ *   a*r = (a0*r0)
+ *       + (a0*r1 + a1*r0) * W
+ *       + (a0*r2 + a1*r1 + a2*r0) * W^2
+ *       + (a1*r2 + a2*r1) * W^3
+ *       + (a2*r2) * W^4
+ *
+ * We want to reduce that value modulo p = 2^130-5, so W^3 = 20 mod p,
+ * and W^4 = 20*W mod p. Thus, if we define u1 = 20*r1 and u2 = 20*r2,
+ * then the equations above become:
+ *
+ *  b0 = a0*r0 + a1*u2 + a2*u1
+ *  b1 = a0*r1 + a1*r0 + a2*u2
+ *  b2 = a0*r2 + a1*r1 + a2*r0
+ *
+ * In order to make u1 fit in 44 bits, we can change these equations
+ * into:
+ *
+ *  b0 = a0*r0 + a1*u2 + a2*t1
+ *  b1 = a0*r1 + a1*r0 + a2*t2
+ *  b2 = a0*r2 + a1*r1 + a2*r0
+ *
+ * Where t1 is u1 truncated to 44 bits, and t2 is u2 added to the extra
+ * bits of u1. Note that since r is clamped down to a 124-bit value, the
+ * values u2 and t2 fit on 44 bits too.
+ *
+ * The bx values are larger than 44 bits, so we may split them into a
+ * lower half (cx, 44 bits) and an upper half (dx). The new values for
+ * the accumulator are then:
+ *
+ *  e0 = c0 + 20*d2
+ *  e1 = c1 + d0
+ *  e2 = c2 + d1
+ *
+ * The equations allow for some room, i.e. the ax values may be larger
+ * than 44 bits. Similarly, the ex values will usually be larger than
+ * the ax. Thus, some sort of carry propagation must be done regularly,
+ * though not necessarily at each iteration. In particular, we do not
+ * need to compute the additions (for the bx values) over 128-bit
+ * quantities; we can stick to 64-bit computations.
+ *
+ *
+ * Since the 128-bit result of a 64x64 multiplication is actually
+ * represented over two 64-bit registers, it is cheaper to arrange for
+ * any split that happens between the "high" and "low" halves to be on
+ * that 64-bit boundary. This is done by left shifting the rx, ux and tx
+ * by 20 bits (since they all fit on 44 bits each, this shift is
+ * always possible).

+\
+\ -- In the preamble, a macro called "CONTEXT_NAME" that evaluates to the

+\ -- A word called "read-blob-inner" ( addr len -- addr len ) that is

+ * Implementation Notes
+ * --------------------
+ *
+ * The C code pushes the data by chunks; all decoding is done in the
+ * T0 code. The cert_length value is set to the certificate length when
+ * a new certificate is started; the T0 code picks it up as outer limit,
+ * and decoding functions use it to ensure that no attempt is made at
+ * reading past it. The T0 code also checks that once the certificate is
+ * decoded, there are no trailing bytes.
+ *
+ * The T0 code sets cert_length to 0 when the certificate is fully
+ * decoded.
+ *
+ * The C code must still perform two checks:
+ *
+ *  -- If the certificate length is 0, then the T0 code will not be
+ *  invoked at all. This invalid condition must thus be reported by the
+ *  C code.
+ *
+ *  -- When reaching the end of certificate, the C code must verify that
+ *  the certificate length has been set to 0, thereby signaling that
+ *  the T0 code properly decoded a certificate.
+ *
+ * Processing of a chain works in the following way:
+ *
+ *  -- The error flag is set to a non-zero value when validation is
+ *  finished. The value is either BR_ERR_X509_OK (validation is
+ *  successful) or another non-zero error code. When a non-zero error
+ *  code is obtained, the remaining bytes in the current certificate and
+ *  the subsequent certificates (if any) are completely ignored.
+ *
+ *  -- Each certificate is decoded in due course, with the following
+ *  "interesting points":
+ *
+ *     -- Start of the TBS: the multihash engine is reset and activated.
+ *
+ *     -- Start of the issuer DN: the secondary hash engine is started,
+ *     to process the encoded issuer DN.
+ *
+ *     -- End of the issuer DN: the secondary hash engine is stopped. The
+ *     resulting hash value is computed and then copied into the
+ *     next_dn_hash[] buffer.
+ *
+ *     -- Start of the subject DN: the secondary hash engine is started,
+ *     to process the encoded subject DN.
+ *
+ *     -- For the EE certificate only: the Common Name, if any, is matched
+ *     against the expected server name.
+ *
+ *     -- End of the subject DN: the secondary hash engine is stopped. The
+ *     resulting hash value is computed into the pad. It is then processed:
+ *
+ *        -- If this is the EE certificate, then the hash is ignored
+ *        (except for direct trust processing, see later; the hash is
+ *        simply left in current_dn_hash[]).
+ *
+ *        -- Otherwise, the hashed subject DN is compared with the saved
+ *        hash value (in saved_dn_hash[]). They must match.
+ *
+ *     Either way, the next_dn_hash[] value is then copied into the
+ *     saved_dn_hash[] value. Thus, at that point, saved_dn_hash[]
+ *     contains the hash of the issuer DN for the current certificate,
+ *     and current_dn_hash[] contains the hash of the subject DN for the
+ *     current certificate.
+ *
+ *     -- Public key: it is decoded into the cert_pkey[] buffer. Unknown
+ *     key types are reported at that point.
+ *
+ *        -- If this is the EE certificate, then the key type is compared
+ *        with the expected key type (initialization parameter). The public
+ *        key data is copied to ee_pkey_data[]. The key and hashed subject
+ *        DN are also compared with the "direct trust" keys; if the key
+ *        and DN are matched, then validation ends with a success.
+ *
+ *        -- Otherwise, the saved signature (cert_sig[]) is verified
+ *        against the saved TBS hash (tbs_hash[]) and that freshly
+ *        decoded public key. Failure here ends validation with an error.
+ *
+ *     -- Extensions: extension values are processed in due order.
+ *
+ *        -- Basic Constraints: for all certificates except EE, must be
+ *        present, indicate a CA, and have a path legnth compatible with
+ *        the chain length so far.
+ *
+ *        -- Key Usage: for the EE, if present, must allow signatures
+ *        or encryption/key exchange, as required for the cipher suite.
+ *        For non-EE, if present, must have the "certificate sign" bit.
+ *
+ *        -- Subject Alt Name: for the EE, dNSName names are matched
+ *        against the server name. Ignored for non-EE.
+ *
+ *        -- Authority Key Identifier, Subject Key Identifier, Issuer
+ *        Alt Name, Subject Directory Attributes, CRL Distribution Points
+ *        Freshest CRL, Authority Info Access and Subject Info Access
+ *        extensions are always ignored: they either contain only
+ *        informative data, or they relate to revocation processing, which
+ *        we explicitly do not support.
+ *
+ *        -- All other extensions are ignored if non-critical. If a
+ *        critical extension other than the ones above is encountered,
+ *        then a failure is reported.
+ *
+ *     -- End of the TBS: the multihash engine is stopped.
+ *
+ *     -- Signature algorithm: the signature algorithm on the
+ *     certificate is decoded. A failure is reported if that algorithm

+/*
+ * Implementation Notes
+ * --------------------
+ *
+ * The C code pushes the data by chunks; all decoding is done in the
+ * T0 code. The cert_length value is set to the certificate length when
+ * a new certificate is started; the T0 code picks it up as outer limit,
+ * and decoding functions use it to ensure that no attempt is made at
+ * reading past it. The T0 code also checks that once the certificate is
+ * decoded, there are no trailing bytes.
+ *
+ * The T0 code sets cert_length to 0 when the certificate is fully
+ * decoded.
+ *
+ * The C code must still perform two checks:
+ *
+ *  -- If the certificate length is 0, then the T0 code will not be
+ *  invoked at all. This invalid condition must thus be reported by the
+ *  C code.
+ *
+ *  -- When reaching the end of certificate, the C code must verify that
+ *  the certificate length has been set to 0, thereby signaling that
+ *  the T0 code properly decoded a certificate.
+ *
+ * Processing of a chain works in the following way:
+ *
+ *  -- The error flag is set to a non-zero value when validation is
+ *  finished. The value is either BR_ERR_X509_OK (validation is
+ *  successful) or another non-zero error code. When a non-zero error
+ *  code is obtained, the remaining bytes in the current certificate and
+ *  the subsequent certificates (if any) are completely ignored.
+ *
+ *  -- Each certificate is decoded in due course, with the following
+ *  "interesting points":
+ *
+ *     -- Start of the TBS: the multihash engine is reset and activated.
+ *
+ *     -- Start of the issuer DN: the secondary hash engine is started,
+ *     to process the encoded issuer DN.
+ *
+ *     -- End of the issuer DN: the secondary hash engine is stopped. The
+ *     resulting hash value is computed and then copied into the
+ *     next_dn_hash[] buffer.
+ *
+ *     -- Start of the subject DN: the secondary hash engine is started,
+ *     to process the encoded subject DN.
+ *
+ *     -- For the EE certificate only: the Common Name, if any, is matched
+ *     against the expected server name.
+ *
+ *     -- End of the subject DN: the secondary hash engine is stopped. The
+ *     resulting hash value is computed into the pad. It is then processed:
+ *
+ *        -- If this is the EE certificate, then the hash is ignored
+ *        (except for direct trust processing, see later; the hash is
+ *        simply left in current_dn_hash[]).
+ *
+ *        -- Otherwise, the hashed subject DN is compared with the saved
+ *        hash value (in saved_dn_hash[]). They must match.
+ *
+ *     Either way, the next_dn_hash[] value is then copied into the
+ *     saved_dn_hash[] value. Thus, at that point, saved_dn_hash[]
+ *     contains the hash of the issuer DN for the current certificate,
+ *     and current_dn_hash[] contains the hash of the subject DN for the
+ *     current certificate.
+ *
+ *     -- Public key: it is decoded into the cert_pkey[] buffer. Unknown
+ *     key types are reported at that point.
+ *
+ *        -- If this is the EE certificate, then the key type is compared
+ *        with the expected key type (initialization parameter). The public
+ *        key data is copied to ee_pkey_data[]. The key and hashed subject
+ *        DN are also compared with the "direct trust" keys; if the key
+ *        and DN are matched, then validation ends with a success.
+ *
+ *        -- Otherwise, the saved signature (cert_sig[]) is verified
+ *        against the saved TBS hash (tbs_hash[]) and that freshly
+ *        decoded public key. Failure here ends validation with an error.
+ *
+ *     -- Extensions: extension values are processed in due order.
+ *
+ *        -- Basic Constraints: for all certificates except EE, must be
+ *        present, indicate a CA, and have a path legnth compatible with
+ *        the chain length so far.
+ *
+ *        -- Key Usage: for the EE, if present, must allow signatures
+ *        or encryption/key exchange, as required for the cipher suite.
+ *        For non-EE, if present, must have the "certificate sign" bit.
+ *
+ *        -- Subject Alt Name: for the EE, dNSName names are matched
+ *        against the server name. Ignored for non-EE.
+ *
+ *        -- Authority Key Identifier, Subject Key Identifier, Issuer
+ *        Alt Name, Subject Directory Attributes, CRL Distribution Points
+ *        Freshest CRL, Authority Info Access and Subject Info Access
+ *        extensions are always ignored: they either contain only
+ *        informative data, or they relate to revocation processing, which
+ *        we explicitly do not support.
+ *
+ *        -- All other extensions are ignored if non-critical. If a
+ *        critical extension other than the ones above is encountered,
+ *        then a failure is reported.
+ *
+ *     -- End of the TBS: the multihash engine is stopped.
+ *
+ *     -- Signature algorithm: the signature algorithm on the
+ *     certificate is decoded. A failure is reported if that algorithm
+ *     is unknown. The hashed TBS corresponding to the signature hash
+ *     function is computed and stored in tbs_hash[] (if not supported,
+ *     then a failure is reported). The hash OID and length are stored
+ *     in cert_sig_hash_oid and cert_sig_hash_len.
+ *
+ *     -- Signature value: the signature value is copied into the
+ *     cert_sig[] array.
+ *
+ *     -- Certificate end: the hashed issuer DN (saved_dn_hash[]) is
+ *     looked up in the trust store (CA trust anchors only); for all
+ *     that match, the signature (cert_sig[]) is verified against the
+ *     anchor public key (hashed TBS is in tbs_hash[]). If one of these
+ *     signatures is valid, then validation ends with a success.
+ *
+ *  -- If the chain end is reached without obtaining a validation success,
+ *  then validation is reported as failed.

+# About
+
+This is version 4.2 of (N)compress (an improved version of compress 4.1).
+
+Compress is a fast, simple LZW file compressor.  Compress does not have
+the highest compression rate, but it is one of the fastest programs to
+compress data.  Compress is the defacto standard in the UNIX community
+for compressing files.
+
+(N)compress 4.2 has a special, fast compression hash algorithm.  This
+algorithm uses more memory than the old hash table. If you don't want
+the faster hash table algorithm set 'Memory free for compress' below
+800000.
+
+zcmp, zdiff, zmore were copied from version 4.1 without any changes.
+
+The output of (N)compress 4.2 is fully compatible with that of compress 3.0.
+In other words, the output of (N)compress 4.2 may be fed into uncompress 3.0 or
+the output of compress 3.0 may be fed into uncompress 4.2.
+
+The output of (N)compress 4.2 is not compatible with that of
+compress 2.0.  However, compress 4.2 still accepts the output of
+compress 2.0.  To generate output that is compatible with compress
+2.0, use the undocumented "-C" flag.
+
+# Building
+
+For recent systems with GNU make, you can simply run `make` as the default
+'GNUMakefile' will get picked up.
+
+'build' is a menu driven shell script for compiling, testing and
+installing (N)compress. So to build and install (N)compress all you have to
+do is run build.  Build will first test your system for default
+settings. The current compile settings are stored in a special file
+called compress.def.
+
+For user with problems with build there is a default makefile included
+called 'Makefile.def'. Also build is capable of generating a Makefile with
+all options (option genmake).
+
+# Support
+
+[![Build Status](https://travis-ci.org/vapier/ncompress.svg?branch=ncompress-4.2.4)](https://travis-ci.org/vapier/ncompress)
+
+Send comments, complaints and especially patches relating to
+    https://github.com/vapier/ncompress/issues
+
+# Licensing
+
+The ncompress code is released into the public domain.  See the
+[UNLICENSE](UNLICENSE) file for more details.
+
+# Patents
+
+All existing patents on the LZW algorithm have
+[expired world-wide](http://en.wikipedia.org/wiki/LZW#Patent_issues).
+So LZW is now patent free.
+
+# Remarks
+
+- Build is a bourne shell script. On some system it is necessary to type
+  'sh build'.
+
+- The build script usages tput for nice screen handling of the script.
+  If your system has no tput no problems.
+
+- For configuration testing build uses a lot of small C programs. During
+  those test stderr is redirected to /dev/null.
+  During the compilation of compress output is NOT redirected.
+
+- The /bin/sh under Ultrix can't handle ${var:-str} so use ksh for the
+  build script.
+
+- The output if (N)compress 4.2 is not exactly the same as compress 4.0
+  because of different table reset point. The output of (N)compress 4.2
+  is 100% compatible with compress 4.0
+
+- Some systems has performance problems with reads bigger than BUFSIZ
+  (The read a head function is not working as expected). For those
+  system use the default BSIZE input buffer size.
+
+- (N)compress can by slower on small files (<10Kb) because of a great
+  table reset overhead. Use cpio or tar to make 1 bigger file if
+  possible, it is faster and also gives a better compression ratio most
+  of the time.
+
+- (N)compress is slower in vax systems because of removing some
+  undocumented inline assembler.
+
+- files compressed on a large machine with more bits than allowed by
+  a version of compress on a smaller machine cannot be decompressed!  Use the
+  "-b12" flag to generate a file on a large machine that can be uncompressed
+  on a 16-bit machine.
+
+- compatibility with compress 3.0 has not been tested in the 4.2 release of
+  (N)compress.
+
+- There has been 1 problem report in relation to GCC 2.0 on a sparc
+  workstation. GCC 2.0 seems to generate a bad compress. Use the
+  standard c compiler 'cc'.

+ *                       (peter@ncs.nl)
+ *
+ * Revision 4.2.3  92/03/14 peter@ncs.nl
+ *   Optimise compress and decompress function and a lot of cleanups.
+ *   New fast hash algoritme added (if more than 800Kb available).
+ *
+ * Revision 4.1  91/05/26 csu@alembic.acs.com
+ *   Modified to recursively compress directories ('r' flag). As a side
+ *   effect, compress will no longer attempt to compress things that
+ *   aren't "regular" files. See Changes.
+ *
+ * Revision 4.0  85/07/30  12:50:00  joe
+ *   Removed ferror() calls in output routine on every output except first.
+ *   Prepared for release to the world.
+ * 
+ * Revision 3.6  85/07/04  01:22:21  joe
+ *   Remove much wasted storage by overlaying hash table with the tables
+ *   used by decompress: tab_suffix[1<<BITS], stack[8000].  Updated USERMEM
+ *   computations.  Fixed dump_tab() DEBUG routine.
+ *
+ * Revision 3.5  85/06/30  20:47:21  jaw
+ *   Change hash function to use exclusive-or.  Rip out hash cache.  These
+ *   speedups render the megamemory version defunct, for now.  Make decoder
+ *   stack global.  Parts of the RCS trunks 2.7, 2.6, and 2.1 no longer apply.
+ *
+ * Revision 3.4  85/06/27  12:00:00  ken
+ *   Get rid of all floating-point calculations by doing all compression ratio
+ *   calculations in fixed point.
+ *
+ * Revision 3.3  85/06/24  21:53:24  joe
+ *   Incorporate portability suggestion for M_XENIX.  Got rid of text on #else
+ *   and #endif lines.  Cleaned up #ifdefs for vax and interdata.
+ *
+ * Revision 3.2  85/06/06  21:53:24  jaw
+ *   Incorporate portability suggestions for Z8000, IBM PC/XT from mailing list.
+ *   Default to "quiet" output (no compression statistics).
+ *
+ * Revision 3.1  85/05/12  18:56:13  jaw
+ *   Integrate decompress() stack speedups (from early pointer mods by McKie).
+ *   Repair multi-file USERMEM gaffe.  Unify 'force' flags to mimic semantics
+ *   of SVR2 'pack'.  Streamline block-compress table clear logic.  Increase 
+ *   output byte count by magic number size.
+ * 
+ * Revision 3.0   84/11/27  11:50:00  petsd!joe
+ *   Set HSIZE depending on BITS.  Set BITS depending on USERMEM.  Unrolled
+ *   loops in clear routines.  Added "-C" flag for 2.0 compatibility.  Used
+ *   unsigned compares on Perkin-Elmer.  Fixed foreground check.
+ *
+ * Revision 2.7   84/11/16  19:35:39  ames!jaw
+ *   Cache common hash codes based on input statistics; this improves
+ *   performance for low-density raster images.  Pass on #ifdef bundle
+ *   from Turkowski.
+ *
+ * Revision 2.6   84/11/05  19:18:21  ames!jaw
+ *   Vary size of hash tables to reduce time for small files.
+ *   Tune PDP-11 hash function.
+ *
+ * Revision 2.5   84/10/30  20:15:14  ames!jaw
+ *   Junk chaining; replace with the simpler (and, on the VAX, faster)
+ *   double hashing, discussed within.  Make block compression standard.
+ *
+ * Revision 2.4   84/10/16  11:11:11  ames!jaw
+ *   Introduce adaptive reset for block compression, to boost the rate
+ *   another several percent.  (See mailing list notes.)
+ *
+ * Revision 2.3   84/09/22  22:00:00  petsd!joe
+ *   Implemented "-B" block compress.  Implemented REVERSE sorting of tab_next.
+ *   Bug fix for last bits.  Changed fwrite to putchar loop everywhere.
+ *
+ * Revision 2.2   84/09/18  14:12:21  ames!jaw
+ *   Fold in news changes, small machine typedef from thomas,
+ *   #ifdef interdata from joe.
+ *
+ * Revision 2.1   84/09/10  12:34:56  ames!jaw
+ *   Configured fast table lookup for 32-bit machines.
+ *   This cuts user time in half for b <= FBITS, and is useful for news batching
+ *   from VAX to PDP sites.  Also sped up decompress() [fwrite->putc] and
+ *   added signal catcher [plus beef in write_error()] to delete effluvia.
+ *
+ * Revision 2.0   84/08/28  22:00:00  petsd!joe
+ *   Add check for foreground before prompting user.  Insert maxbits into
+ *   compressed file.  Force file being uncompressed to end with ".Z".
+ *   Added "-c" flag and "zcat".  Prepared for release.
+ *
+ * Revision 1.10  84/08/24  18:28:00  turtlevax!ken
+ *   Will only compress regular files (no directories), added a magic number
+ *   header (plus an undocumented -n flag to handle old files without headers),
+ *   added -f flag to force overwriting of possibly existing destination file,
+ *   otherwise the user is prompted for a response.  Will tack on a .Z to a
+ *   filename if it doesn't have one when decompressing.  Will only replace
+ *   file if it was compressed.
+ *
+ * Revision 1.9  84/08/16  17:28:00  turtlevax!ken
+ *   Removed scanargs(), getopt(), added .Z extension and unlimited number of
+ *   filenames to compress.  Flags may be clustered (-Ddvb12) or separated
+ *   (-D -d -v -b 12), or combination thereof.  Modes and other status is
+ *   copied with copystat().  -O bug for 4.2 seems to have disappeared with
+ *   1.8.
+ *
+ * Revision 1.8  84/08/09  23:15:00  joe
+ *   Made it compatible with vax version, installed jim's fixes/enhancements
+ *
+ * Revision 1.6  84/08/01  22:08:00  joe
+ *   Sped up algorithm significantly by sorting the compress chain.
+ *
+ * Revision 1.5  84/07/13  13:11:00  srd
+ *   Added C version of vax asm routines.  Changed structure to arrays to
+ *   save much memory.  Do unsigned compares where possible (faster on
+ *   Perkin-Elmer)
+ *
+ * Revision 1.4  84/07/05  03:11:11  thomas
+ *   Clean up the code a little and lint it.  (Lint complains about all
+ *   the regs used in the asm, but I'm not going to "fix" this.)
+ *
+ * Revision 1.3  84/07/05  02:06:54  thomas
+ *   Minor fixes.
+ *
+ * Revision 1.2  84/07/05  00:27:27  thomas
+ *   Add variable bit length output.

+/*****************************************************************
+ * TAG( main )
+ *
+ * Algorithm from "A Technique for High Performance Data Compression",
+ * Terry A. Welch, IEEE Computer Vol 17, No 6 (June 1984), pp 8-19.
+ *
+ * Usage: compress [-dfvc] [-b bits] [file ...]
+ * Inputs:
+ *   -d:     If given, decompression is done instead.
+ *
+ *   -c:     Write output on stdout, don't remove original.
+ *
+ *   -b:     Parameter limits the max number of bits/code.
+ *
+ *   -f:     Forces output file to be generated, even if one already
+ *           exists, and even if no space is saved by compressing.
+ *           If -f is not used, the user will be prompted if stdin is
+ *           a tty, otherwise, the output file will not be overwritten.
+ *
+ *   -v:     Write compression statistics
+ *
+ *   -r:     Recursive. If a filename is a directory, descend
+ *           into it and compress everything in it.
+ *
+ * file ...:
+ *           Files to be compressed.  If none specified, stdin is used.
+ * Outputs:
+ *   file.Z:     Compressed form of file with same mode, owner, and utimes
+ *   or stdout   (if stdin used as input)
+ *
+ * Assumptions:
+ *   When filenames are given, replaces with the compressed version
+ *   (.Z suffix) only if the file decreases in size.
+ *
+ * Algorithm:
+ *   Modified Lempel-Ziv method (LZW).  Basically finds common
+ *   substrings and replaces them with a variable size code.  This is
+ *   deterministic, and can be done on the fly.  Thus, the decompression
+ *   procedure needs no input table, but tracks the way the table was built.

+ *	idea.c - C source code for IDEA block cipher.
+ *	IDEA (International Data Encryption Algorithm), formerly known as 
+ *	IPES (Improved Proposed Encryption Standard).
+ *	Algorithm developed by Xuejia Lai and James L. Massey, of ETH Zurich.
+ *	This implementation modified and derived from original C code 
+ *	developed by Xuejia Lai.  
+ *	Zero-based indexing added, names changed from IPES to IDEA.
+ *	CFB functions added.  Random number routines added.
+ *
+ *	Extensively optimized and restructured by Colin Plumb.
+ *
+ *	There are two adjustments that can be made to this code to
+ *	speed it up.  Defaults may be used for PCs.  Only the -DIDEA32
+ *	pays off significantly if selectively set or not set.
+ *	Experiment to see what works best for your machine.
+ *
+ *	Multiplication: default is inline, -DAVOID_JUMPS uses a
+ *		different version that does not do any conditional
+ *		jumps (a few percent worse on a SPARC), while
+ *		-DSMALL_CACHE takes it out of line to stay
+ *		within a small on-chip code cache.
+ *	Variables: normally, 16-bit variables are used, but some
+ *		machines (notably RISCs) do not have 16-bit registers,
+ *		so they do a great deal of masking.  -DIDEA32 uses "int"
+ *		register variables and masks explicitly only where
+ *		necessary.  On a SPARC, for example, this boosts
+ *		performace by 30%.
+ *
+ *	The IDEA(tm) block cipher is covered by patents held by ETH and a
+ *	Swiss company called Ascom-Tech AG.  The Swiss patent number is
+ *	PCT/CH91/00117, the European patent number is EP 0 482 154 B1, and
+ *	the U.S. patent number is US005214703.  IDEA(tm) is a trademark of
+ *	Ascom-Tech AG.  There is no license fee required for noncommercial
+ *	use.  Commercial users may obtain licensing details from Dieter
+ *	Profos, Ascom Tech AG, Solothurn Lab, Postfach 151, 4502 Solothurn,
+ *	Switzerland, Tel +41 65 242885, Fax +41 65 235761.
+ *
+ *	The IDEA block cipher uses a 64-bit block size, and a 128-bit key 
+ *	size.  It breaks the 64-bit cipher block into four 16-bit words
+ *	because all of the primitive inner operations are done with 16-bit 
+ *	arithmetic.  It likewise breaks the 128-bit cipher key into eight 
+ *	16-bit words.
+ *
+ *	For further information on the IDEA cipher, see the book:
+ *	  Xuejia Lai, "On the Design and Security of Block Ciphers",
+ *	  ETH Series on Information Processing (ed. J.L. Massey) Vol 1,
+ *	  Hartung-Gorre Verlag, Konstanz, Switzerland, 1992.  ISBN
+ *	  3-89191-573-X.
+ *
+ *	This code runs on arrays of bytes by taking pairs in big-endian
+ *	order to make the 16-bit words that IDEA uses internally.  This
+ *	produces the same result regardless of the byte order of the
+ *	native CPU.

- * This file is part of the Independent JPEG Group's software.

- *
- * This file contains a command-line user interface for the JPEG compressor.
- * It should work on any system with Unix- or MS-DOS-style command lines.
- *
- * Two different command line styles are permitted, depending on the
- * compile-time switch TWO_FILE_COMMANDLINE:
- *	cjpeg [options]  inputfile outputfile
- *	cjpeg [options]  [inputfile]
- * In the second style, output is always to standard output, which you'd
- * normally redirect to a file or pipe to some other program.  Input is
- * either from a named file or from standard input (typically redirected).
- * The second style is convenient on Unix but is unhelpful on systems that
- * don't support pipes.  Also, you MUST use the first style if your system
- * doesn't do binary I/O to stdin/stdout.
- * To simplify script writing, the "-outfile" switch is provided.  The syntax
- *	cjpeg [options]  -outfile outputfile  inputfile
- * works regardless of which command line style is used.

- * This routine determines what format the input file is,
- * and selects the appropriate input-reading module.
- *
- * To determine which family of input formats the file belongs to,
- * we may look only at the first byte of the file, since C does not
- * guarantee that more than one character can be pushed back with ungetc.
- * Looking at additional bytes would require one of these approaches:
- *     1) assume we can fseek() the input file (fails for piped input);
- *     2) assume we can push back more than one character (works in
- *        some C implementations, but unportable);
- *     3) provide our own buffering (breaks input readers that want to use
- *        stdio directly, such as the RLE library);
- * or  4) don't put back the data, and modify the input_init methods to assume
- *        they start reading after the start of file (also breaks RLE library).
- * #1 is attractive for MS-DOS but is untenable on Unix.
- *
- * The most portable solution for file types that can't be identified by their
- * first byte is to make the user tell us what they are.  This is also the
- * only approach for "raw" file types that contain only arbitrary values.
- * We presently apply this method for Targa files.  Most of the time Targa
- * files start with 0x00, so we recognize that case.  Potentially, however,
- * a Targa file could start with any byte value (byte 0 is the length of the
- * seldom-used ID field), so we provide a switch to force Targa input mode.

+ * #1 is attractive for MS-DOS but is untenable on Unix.
+ *
+ * The most portable solution for file types that can't be identified by their
+ * first byte is to make the user tell us what they are.  This is also the

- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains a command-line user interface for the JPEG decompressor.
- * It should work on any system with Unix- or MS-DOS-style command lines.
- *
- * Two different command line styles are permitted, depending on the
- * compile-time switch TWO_FILE_COMMANDLINE:
- *	djpeg [options]  inputfile outputfile
- *	djpeg [options]  [inputfile]
- * In the second style, output is always to standard output, which you'd
- * normally redirect to a file or pipe to some other program.  Input is
- * either from a named file or from standard input (typically redirected).
- * The second style is convenient on Unix but is unhelpful on systems that
- * don't support pipes.  Also, you MUST use the first style if your system
- * doesn't do binary I/O to stdin/stdout.
- * To simplify script writing, the "-outfile" switch is provided.  The syntax
- *	djpeg [options]  -outfile outputfile  inputfile
- * works regardless of which command line style is used.

- * On some systems you may need to set up a signal handler to ensure that
- * temporary files are deleted if the program is interrupted.  See libjpeg.doc.

- * Scanlines MUST be supplied in top-to-bottom order if you want your JPEG
- * files to be compatible with everyone else's.  If you cannot readily read

- * ERROR HANDLING:

- * have to update with each future release.
- *
- * Our example here shows how to override the "error_exit" method so that
- * control is returned to the library's caller when a fatal error occurs,
- * rather than calling exit() as the standard error_exit method does.
- *
- * We use C's setjmp/longjmp facility to return control.  This means that the
- * routine which calls the JPEG library must first execute a setjmp() call to
- * establish the return point.  We want the replacement error_exit to do a
- * longjmp().  But we need to make the setjmp buffer accessible to the
- * error_exit routine.  To do this, we make a private extension of the
- * standard JPEG error handler object.  (If we were using C++, we'd say we
- * were making a subclass of the regular error handler.)

+ * establish the return point.  We want the replacement error_exit to do a
+ * longjmp().  But we need to make the setjmp buffer accessible to the
+ * error_exit routine.  To do this, we make a private extension of the
+ * standard JPEG error handler object.  (If we were using C++, we'd say we
+ * were making a subclass of the regular error handler.)

- * About virtual array management:
- *
- * The above "normal" array routines are only used to allocate strip buffers
- * (as wide as the image, but just a few rows high).  Full-image-sized buffers
- * are handled as "virtual" arrays.  The array is still accessed a strip at a
- * time, but the memory manager must save the whole array for repeated
- * accesses.  The intended implementation is that there is a strip buffer in
- * memory (as high as is possible given the desired memory limit), plus a
- * backing file that holds the rest of the array.
- *
- * The request_virt_array routines are told the total size of the image and
- * the maximum number of rows that will be accessed at once.  The in-memory
- * buffer must be at least as large as the maxaccess value.
- *
- * The request routines create control blocks but not the in-memory buffers.
- * That is postponed until realize_virt_arrays is called.  At that time the
- * total amount of space needed is known (approximately, anyway), so free
- * memory can be divided up fairly.
- *
- * The access_virt_array routines are responsible for making a specific strip
- * area accessible (after reading or writing the backing file, if necessary).
- * Note that the access routines are told whether the caller intends to modify
- * the accessed strip; during a read-only pass this saves having to rewrite
- * data to disk.  The access routines are also responsible for pre-zeroing
- * any newly accessed rows, if pre-zeroing was requested.
- *
- * In current usage, the access requests are usually for nonoverlapping
- * strips; that is, successive access start_row numbers differ by exactly
- * num_rows = maxaccess.  This means we can get good performance with simple
- * buffer dump/reload logic, by making the in-memory buffer be a multiple
- * of the access height; then there will never be accesses across bufferload
- * boundaries.  The code will still work with overlapping access requests,
- * but it doesn't handle bufferload overlaps very efficiently.

+ * About virtual array management:
+ *
+ * The above "normal" array routines are only used to allocate strip buffers
+ * (as wide as the image, but just a few rows high).  Full-image-sized buffers
+ * are handled as "virtual" arrays.  The array is still accessed a strip at a
+ * time, but the memory manager must save the whole array for repeated
+ * accesses.  The intended implementation is that there is a strip buffer in
+ * memory (as high as is possible given the desired memory limit), plus a
+ * backing file that holds the rest of the array.
+ *
+ * The request_virt_array routines are told the total size of the image and
+ * the maximum number of rows that will be accessed at once.  The in-memory
+ * buffer must be at least as large as the maxaccess value.
+ *
+ * The request routines create control blocks but not the in-memory buffers.
+ * That is postponed until realize_virt_arrays is called.  At that time the
+ * total amount of space needed is known (approximately, anyway), so free
+ * memory can be divided up fairly.
+ *
+ * The access_virt_array routines are responsible for making a specific strip
+ * area accessible (after reading or writing the backing file, if necessary).
+ * Note that the access routines are told whether the caller intends to modify
+ * the accessed strip; during a read-only pass this saves having to rewrite
+ * data to disk.  The access routines are also responsible for pre-zeroing
+ * any newly accessed rows, if pre-zeroing was requested.
+ *
+ * In current usage, the access requests are usually for nonoverlapping
+ * strips; that is, successive access start_row numbers differ by exactly
+ * num_rows = maxaccess.  This means we can get good performance with simple
+ * buffer dump/reload logic, by making the in-memory buffer be a multiple
+ * of the access height; then there will never be accesses across bufferload
+ * boundaries.  The code will still work with overlapping access requests,
+ * but it doesn't handle bufferload overlaps very efficiently.

+                 MW = caml_stat_heap_wsz * 100 / (100 + caml_percent_free)
+                      + caml_incremental_roots_count
+     Amount of sweeping work for the GC cycle:
+                 SW = caml_stat_heap_wsz
+
+     In order to finish marking with a non-empty free list, we will
+     use 40% of the time for marking, and 60% for sweeping.
+
+     Let MT be the time spent marking, ST the time spent sweeping, and TT
+     the total time for this cycle. We have:
+                 MT = 40/100 * TT
+                 ST = 60/100 * TT
+
+     Amount of time to spend on this slice:
+                 T  = P * TT = P * MT / (40/100) = P * ST / (60/100)
+
+     Since we must do MW work in MT time or SW work in ST time, the amount
+     of work for this slice is:
+                 MS = P * MW / (40/100)  if marking
+                 SS = P * SW / (60/100)  if sweeping
+
+     Amount of marking work for a marking slice:
+                 MS = P * MW / (40/100)
+                 MS = P * (caml_stat_heap_wsz * 250 / (100 + caml_percent_free)
+                           + 2.5 * caml_incremental_roots_count)
+     Amount of sweeping work for a sweeping slice:
+                 SS = P * SW / (60/100)
+                 SS = P * caml_stat_heap_wsz * 5 / 3
+
+     This slice will either mark MS words or sweep SS words.

+   A specific phase of the GC is dedicated to this, Phase_clean. This
+   phase is just after the mark phase, so the white values are dead
+   values. It iterates the function caml_ephe_clean through all the
+   ephemerons.
+
+   However the GC is incremental and ocaml code can run on the middle
+   of this cleaning phase. In order to respect the semantic of the
+   ephemerons concerning dead values, the getter and setter must work
+   as if the cleaning of all the ephemerons have been done at once.
+
+   - key getter: Even if a dead key have not yet been replaced by
+     caml_ephe_none, getting it should return none.
+   - key setter: If we replace a dead key we need to set the data to
+     caml_ephe_none and clean the ephemeron.
+
+     This two cases are dealt by a call to do_check_key_clean that
+     trigger the cleaning of the ephemerons when the accessed key is
+     dead. This test is fast.
+
+     In the case of value getter and value setter, there is no fast
+     test because the removing of the data depend of the deadliness of the keys.
+     We must always try to clean the ephemerons.

+ * Based on code provided by Olivier Andrieu.
+
+ * An EXCEPTION_STACK_OVERFLOW is signaled when the guard page at the
+ * end of the stack has been accessed. Windows clears the PAGE_GUARD
+ * protection (making it a regular PAGE_READWRITE) and then calls our
+ * exception handler. This means that although we're handling an "out
+ * of stack" condition, there is a bit of stack available to call
+ * functions and allocate temporaries.
+ *
+ * PAGE_GUARD is a one-shot access protection mechanism: we need to
+ * restore the PAGE_GUARD protection on this page otherwise the next
+ * stack overflow won't be detected and the program will abruptly exit
+ * with STATUS_ACCESS_VIOLATION.
+ *
+ * Visual Studio 2003 and later (_MSC_VER >= 1300) have a
+ * _resetstkoflw() function that resets this protection.
+ * Unfortunately, it cannot work when called directly from the
+ * exception handler because at this point we are using the page that
+ * is to be protected.
+ *
+ * A solution is to use an alternate stack when restoring the
+ * protection. However it's not possible to use _resetstkoflw() then
+ * since it determines the stack pointer by calling alloca(): it would
+ * try to protect the alternate stack.
+ *
+ * Finally, we call caml_raise_stack_overflow; it will either call
+ * caml_raise_exception which switches back to the normal stack, or
+ * call caml_fatal_uncaught_exception which terminates the program
+ * quickly.

-/* Handling of system stack overflow.
- * Based on code provided by Olivier Andrieu.
-
- * An EXCEPTION_STACK_OVERFLOW is signaled when the guard page at the
- * end of the stack has been accessed. Windows clears the PAGE_GUARD
- * protection (making it a regular PAGE_READWRITE) and then calls our
- * exception handler. This means that although we're handling an "out
- * of stack" condition, there is a bit of stack available to call
- * functions and allocate temporaries.
- *
- * PAGE_GUARD is a one-shot access protection mechanism: we need to
- * restore the PAGE_GUARD protection on this page otherwise the next
- * stack overflow won't be detected and the program will abruptly exit
- * with STATUS_ACCESS_VIOLATION.
- *
- * Visual Studio 2003 and later (_MSC_VER >= 1300) have a
- * _resetstkoflw() function that resets this protection.
- * Unfortunately, it cannot work when called directly from the
- * exception handler because at this point we are using the page that
- * is to be protected.
- *
- * A solution is to use an alternate stack when restoring the
- * protection. However it's not possible to use _resetstkoflw() then
- * since it determines the stack pointer by calling alloca(): it would
- * try to protect the alternate stack.
- *
- * Finally, we call caml_raise_stack_overflow; it will either call
- * caml_raise_exception which switches back to the normal stack, or
- * call caml_fatal_uncaught_exception which terminates the program
- * quickly.

+/* PCRE2 is written in Standard C, but there are a few non-standard things it
+can cope with, allowing it to run on SunOS4 and other "close to standard"
+systems.
+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,
+config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
+hand" without using "configure" or CMake, you should copy the distributed
+config.h.generic to config.h, and edit the macro definitions to be the way you
+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
+defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
+such macros are listed as a commented #undef in config.h.generic. Macros such
+as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
+
+PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
+sure both macros are undefined; an emulation function will then be used. */
+
+/* By default, the \R escape sequence matches any Unicode line ending
+   character or sequence of characters. If BSR_ANYCRLF is defined (to any

+*           Check for POSIX class syntax         *
+*************************************************/
+
+/* This function is called when the sequence "[:" or "[." or "[=" is
+encountered in a character class. It checks whether this is followed by a
+sequence of characters terminated by a matching ":]" or ".]" or "=]". If we
+reach an unescaped ']' without the special preceding character, return FALSE.
+
+Originally, this function only recognized a sequence of letters between the
+terminators, but it seems that Perl recognizes any sequence of characters,
+though of course unknown POSIX names are subsequently rejected. Perl gives an
+"Unknown POSIX class" error for [:f\oo:] for example, where previously PCRE
+didn't consider this to be a POSIX class. Likewise for [:1234:].
+
+The problem in trying to be exactly like Perl is in the handling of escapes. We
+have to be sure that [abc[:x\]pqr] is *not* treated as containing a POSIX
+class, but [abc[:x\]pqr:]] is (so that an error can be generated). The code
+below handles the special cases \\ and \], but does not try to do any other
+escape processing. This makes it different from Perl for cases such as
+[:l\ower:] where Perl recognizes it as the POSIX class "lower" but PCRE does
+not recognize "l\ower". This is a lesser evil than not diagnosing bad classes
+when Perl does, I think.
+
+A user pointed out that PCRE was rejecting [:a[:digit:]] whereas Perl was not.
+It seems that the appearance of a nested POSIX class supersedes an apparent
+external class. For example, [:a[:digit:]b:] matches "a", "b", ":", or
+a digit. This is handled by returning FALSE if the start of a new group with
+the same terminator is encountered, since the next closing sequence must close
+the nested group, not the outer one.
+
+In Perl, unescaped square brackets may also appear as part of class names. For
+example, [:a[:abc]b:] gives unknown POSIX class "[:abc]b:]". However, for
+[:a[:abc]b][b:] it gives unknown POSIX class "[:abc]b][b:]", which does not
+seem right at all. PCRE does not allow closing square brackets in POSIX class
+names.

+/* This module contains the external function pcre2_dfa_match(), which is an
+alternative matching function that uses a sort of DFA algorithm (not a true
+FSM). This is NOT Perl-compatible, but it has advantages in certain
+applications. */
+
+
+/* NOTE ABOUT PERFORMANCE: A user of this function sent some code that improved
+the performance of his patterns greatly. I could not use it as it stood, as it
+was not thread safe, and made assumptions about pattern sizes. Also, it caused
+test 7 to loop, and test 9 to crash with a segfault.
+
+The issue is the check for duplicate states, which is done by a simple linear
+search up the state list. (Grep for "duplicate" below to find the code.) For
+many patterns, there will never be many states active at one time, so a simple
+linear search is fine. In patterns that have many active states, it might be a
+bottleneck. The suggested code used an indexing scheme to remember which states
+had previously been used for each character, and avoided the linear search when
+it knew there was no chance of a duplicate. This was implemented when adding
+states to the state lists.
+
+I wrote some thread-safe, not-limited code to try something similar at the time
+of checking for duplicates (instead of when adding states), using index vectors
+on the stack. It did give a 13% improvement with one specially constructed
+pattern for certain subject strings, but on other strings and on many of the
+simpler patterns in the test suite it did worse. The major problem, I think,
+was the extra time to initialize the index. This had to be done for each call
+of internal_dfa_match(). (The supplied patch used a static vector, initialized
+only once - I suspect this was the cause of the problems with the tests.)
+
+Overall, I concluded that the gains in some cases did not outweigh the losses
+in others, so I abandoned this code. */

+the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
+is enabled. When UTF-8 support is not enabled, the definitions use character
+literals. Both character and string versions of each character are needed, and
+there are some longer strings as well.
+
+This means that, on EBCDIC platforms, the PCRE2 library can handle either
+EBCDIC, or UTF-8, but not both. To support both in the same compiled library
+would need different lookups depending on whether PCRE2_UTF was set or not.
+This would make it impossible to use characters in switch/case statements,
+which would reduce performance. For a theoretical use (which nobody has asked
+for) in a minority area (EBCDIC platforms), this is not sensible. Any
+application that did need both could compile two versions of the library, using
+macros to give the functions distinct names. */

+(always stored in big-endian order in 8-bit mode) by default. These are used,
+for example, to link from the start of a subpattern to its alternatives and its
+end. The use of 16 bits per offset limits the size of an 8-bit compiled regex
+to around 64K, which is big enough for almost everybody. However, I received a
+request for an even bigger limit. For this reason, and also to make the code
+easier to maintain, the storing and loading of offsets from the compiled code

+Short summary about the backtracking mechanism empolyed by the jit code generator:
+
+The code generator follows the recursive nature of the PERL compatible regular
+expressions. The basic blocks of regular expressions are condition checkers
+whose execute different commands depending on the result of the condition check.
+The relationship between the operators can be horizontal (concatenation) and
+vertical (sub-expression) (See struct backtrack_common for more details).
+
+  'ab' - 'a' and 'b' regexps are concatenated
+  'a+' - 'a' is the sub-expression of the '+' operator
+
+The condition checkers are boolean (true/false) checkers. Machine code is generated
+for the checker itself and for the actions depending on the result of the checker.
+The 'true' case is called as the matching path (expected path), and the other is called as
+the 'backtrack' path. Branch instructions are expesive for all CPUs, so we avoid taken
+branches on the matching path.
+
+ Greedy star operator (*) :
+   Matching path: match happens.
+   Backtrack path: match failed.
+ Non-greedy star operator (*?) :
+   Matching path: no need to perform a match.
+   Backtrack path: match is required.
+
+The following example shows how the code generated for a capturing bracket
+with two alternatives. Let A, B, C, D are arbirary regular expressions, and
+we have the following regular expression:
+
+   A(B|C)D
+
+The generated code will be the following:
+
+ A matching path
+ '(' matching path (pushing arguments to the stack)
+ B matching path
+ ')' matching path (pushing arguments to the stack)
+ D matching path
+ return with successful match
+
+ D backtrack path
+ ')' backtrack path (If we arrived from "C" jump to the backtrack of "C")
+ B backtrack path
+ C expected path
+ jump to D matching path
+ C backtrack path
+ A backtrack path
+
+ Notice, that the order of backtrack code paths are the opposite of the fast
+ code paths. In this way the topmost value on the stack is always belong
+ to the current backtrack code path. The backtrack path must check
+ whether there is a next alternative. If so, it needs to jump back to
+ the matching path eventually. Otherwise it needs to clear out its own stack
+ frame and continue the execution on the backtrack code paths.
+*/
+
+/*
+Saved stack frames:
+
+Atomic blocks and asserts require reloading the values of private data
+when the backtrack mechanism performed. Because of OP_RECURSE, the data
+are not necessarly known in compile time, thus we need a dynamic restore
+mechanism.
+
+The stack frames are stored in a chain list, and have the following format:
+([ capturing bracket offset ][ start value ][ end value ])+ ... [ 0 ] [ previous head ]
+
+Thus we can restore the private data to a particular point in the stack.

+
+The original match() function was highly recursive, but this proved to be the
+source of a number of problems over the years, mostly because of the relatively
+small system stacks that are commonly found. As new features were added to
+patterns, various kludges were invented to reduce the amount of stack used,
+making the code hard to understand in places.
+
+A version did exist that used individual frames on the heap instead of calling
+match() recursively, but this ran substantially slower. The current version is
+a refactoring that uses a vector of frames to remember backtracking points.
+This runs no slower, and possibly even a bit faster than the original recursive
+implementation. An initial vector of size START_FRAMES_SIZE (enough for maybe
+50 frames) is allocated on the system stack. If this is not big enough, the
+heap is used for a larger vector.

+*************************************************/
+
+/* This function applies a compiled pattern to a subject string and picks out
+portions of the string if it matches. Two elements in the vector are set for
+each substring: the offsets to the start and end of the substring.
+
+Arguments:
+  code            points to the compiled expression
+  subject         points to the subject string
+  length          length of subject string (may contain binary zeros)
+  start_offset    where to start in the subject string
+  options         option bits
+  match_data      points to a match_data block
+  mcontext        points a PCRE2 context
+
+Returns:          > 0 => success; value is the number of ovector pairs filled
+                  = 0 => success, but ovector is not big enough
+                   -1 => failed to match (PCRE2_ERROR_NOMATCH)
+                   -2 => partial match (PCRE2_ERROR_PARTIAL)

+10 and 11. The 2-dimensional table is indexed by the properties of two adjacent
+code points. The left property selects a word from the table, and the right
+property selects a bit from that word like this:
+
+  PRIV(ucp_gbtable)[left-property] & (1 << right-property)
+
+The value is non-zero if a grapheme break is NOT permitted between the relevant
+two code points. The breaking rules are as follows:
+
+1. Break at the start and end of text (pretty obviously).
+
+2. Do not break between a CR and LF; otherwise, break before and after
+   controls.
+
+3. Do not break Hangul syllable sequences, the rules for which are:
+
+    L may be followed by L, V, LV or LVT
+    LV or V may be followed by V or T
+    LVT or T may be followed by T
+
+4. Do not break before extending characters or zero-width-joiner (ZWJ).
+
+The following rules are only for extended grapheme clusters (but that's what we
+are implementing).
+
+5. Do not break before SpacingMarks.
+
+6. Do not break after Prepend characters.
+
+7. Do not break within emoji modifier sequences or emoji zwj sequences. That
+   is, do not break between characters with the Extended_Pictographic property.
+   Extend and ZWJ characters are allowed between the characters; this cannot be
+   represented in this table, the code has to deal with it.
+
+8. Do not break within emoji flag sequences. That is, do not break between
+   regional indicator (RI) symbols if there are an odd number of RI characters
+   before the break point. This table encodes "join RI characters"; the code
+   has to deal with checking for previous adjoining RIs.
+
+9. Otherwise, break everywhere.

+*************************************************/
+
+/* In UTF mode the input is always interpreted as a string of UTF-8 bytes using
+the original UTF-8 definition of RFC 2279, which allows for up to 6 bytes, and
+code values from 0 to 0x7fffffff. However, values greater than the later UTF
+limit of 0x10ffff cause an error.
+
+In non-UTF mode the input is interpreted as UTF-8 if the utf8_input modifier
+is set, and no limit is imposed. There is special interpretation of the 0xff
+byte (which is illegal in UTF-8) in this case: it causes the top bit of the
+next character to be set. This provides a way of generating 32-bit characters
+greater than 0x7fffffff.
+
+If all the input bytes are ASCII, the space needed for a 32-bit string is
+exactly four times the 8-bit size. Otherwise, the size needed for a 32-bit
+string is no more than four times, because the number of characters must be
+less than the number of bytes. The result is always left in pbuffer32. Impose a
+minimum size to save repeated re-sizing.
+
+Note that this function does not object to surrogate values. This is
+deliberate; it makes it possible to construct UTF-32 strings that are invalid,
+for the purpose of testing that they are correctly faulted.
+
+Arguments:

+ This program is part of the TACLeBench benchmark suite.
+ Version V 1.x
+
+ Name: powerwindow
+
+ Author: CoSys-Lab, University of Antwerp
+
+ Function: powerwindow implement the powerwindow that can be seen in cars nowadays.
+	The window can be controlled by either driver or passenger. When an object is
+	detected between the window frame and the glass during the raising of the glass,
+	the glass will lower down for some distance. This benchmark contains 4 tasks which includes the
+	driver side powerwindow, front passenger side powerwindow, back-left passenger side powerwindow,
+	back-right passenger side powerwindow. These 4 tasks can be easily adjusted to execute in
+	sequential order parallel on single or muti core.

Subject: If-conversion optimization

Extends the instruction selection pass with an if-conversion optimization:
some if/then/else statements are converted into "select" operations,
which in turn can be compiled down to branchless instruction sequences
if the target architecture supports them.

The statements that are converted are of the form

        if (cond) { x = a1; } else { x = a2; }
        if (cond) { x = a1; }
        if (cond) { /*skip*/; } else { x = a2; }

where a1, a2 are "safe" expressions, containing no operations that can
fail at run-time, such as memory loads or integer divisions.

A heuristic in backend/Selectionaux.ml controls when the optimization occurs,
depending on command-line flags and the complexity of the "then" and "else"
branches.

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is

+ * Given a representation of the nonzero pattern of a symmetric matrix, A,
+ * (excluding the diagonal) perform an approximate minimum (UMFPACK/MA38-style)
+ * degree ordering to compute a pivot order such that the introduction of
+ * nonzeros (fill-in) in the Cholesky factors A = LL' is kept low.  At each
+ * step, the pivot selected is the one with the minimum UMFAPACK/MA38-style
+ * upper-bound on the external degree.  This routine can optionally perform
+ * aggresive absorption (as done by MC47B in the Harwell Subroutine
+ * Library).
+ *
+ * The approximate degree algorithm implemented here is the symmetric analog of
+ * the degree update algorithm in MA38 and UMFPACK (the Unsymmetric-pattern
+ * MultiFrontal PACKage, both by Davis and Duff).  The routine is based on the
+ * MA27 minimum degree ordering algorithm by Iain Duff and John Reid.
+ *
+ * This routine is a translation of the original AMDBAR and MC47B routines,
+ * in Fortran, with the following modifications:
+ *
+ * (1) dense rows/columns are removed prior to ordering the matrix, and placed
+ *      last in the output order.  The presence of a dense row/column can
+ *      increase the ordering time by up to O(n^2), unless they are removed
+ *      prior to ordering.
+ *
+ * (2) the minimum degree ordering is followed by a postordering (depth-first
+ *      search) of the assembly tree.  Note that mass elimination (discussed
+ *      below) combined with the approximate degree update can lead to the mass
+ *      elimination of nodes with lower exact degree than the current pivot
+ *      element.  No additional fill-in is caused in the representation of the
+ *      Schur complement.  The mass-eliminated nodes merge with the current
+ *      pivot element.  They are ordered prior to the current pivot element.
+ *      Because they can have lower exact degree than the current element, the
+ *      merger of two or more of these nodes in the current pivot element can
+ *      lead to a single element that is not a "fundamental supernode".  The
+ *      diagonal block can have zeros in it.  Thus, the assembly tree used here
+ *      is not guaranteed to be the precise supernodal elemination tree (with
+ *      "funadmental" supernodes), and the postordering performed by this
+ *      routine is not guaranteed to be a precise postordering of the
+ *      elimination tree.
+ *
+ * (3) input parameters are added, to control aggressive absorption and the
+ *      detection of "dense" rows/columns of A.
+ *
+ * (4) additional statistical information is returned, such as the number of
+ *      nonzeros in L, and the flop counts for subsequent LDL' and LU
+ *      factorizations.  These are slight upper bounds, because of the mass
+ *      elimination issue discussed above.
+ *
+ * (5) additional routines are added to interface this routine to MATLAB

+ *      We list below the features mentioned in that paper that this code
+ *      includes:
+ *
+ *      mass elimination:
+ *          Yes.  MA27 relied on supervariable detection for mass elimination.
+ *
+ *      indistinguishable nodes:
+ *          Yes (we call these "supervariables").  This was also in the MA27
+ *          code - although we modified the method of detecting them (the
+ *          previous hash was the true degree, which we no longer keep track
+ *          of).  A supervariable is a set of rows with identical nonzero
+ *          pattern.  All variables in a supervariable are eliminated together.
+ *          Each supervariable has as its numerical name that of one of its
+ *          variables (its principal variable).
+ *
+ *      quotient graph representation:
+ *          Yes.  We use the term "element" for the cliques formed during
+ *          elimination.  This was also in the MA27 code.  The algorithm can
+ *          operate in place, but it will work more efficiently if given some
+ *          "elbow room."
+ *
+ *      element absorption:
+ *          Yes.  This was also in the MA27 code.
+ *
+ *      external degree:
+ *          Yes.  The MA27 code was based on the true degree.
+ *
+ *      incomplete degree update and multiple elimination:
+ *          No.  This was not in MA27, either.  Our method of degree update
+ *          within MC47B is element-based, not variable-based.  It is thus
+ *          not well-suited for use with incomplete degree update or multiple
+ *          elimination.

+
+ * ----------------------------------------------------------------------------
+ * INPUT ARGUMENTS (unaltered):
+ * ----------------------------------------------------------------------------
+
+ * n:  The matrix order.  Restriction:  n >= 1.
+ *
+ * iwlen:  The size of the Iw array.  On input, the matrix is stored in
+ *      Iw [0..pfree-1].  However, Iw [0..iwlen-1] should be slightly larger
+ *      than what is required to hold the matrix, at least iwlen >= pfree + n.
+ *      Otherwise, excessive compressions will take place.  The recommended
+ *      value of iwlen is 1.2 * pfree + n, which is the value used in the
+ *      user-callable interface to this routine (amd_order.c).  The algorithm
+ *      will not run at all if iwlen < pfree.  Restriction: iwlen >= pfree + n.
+ *      Note that this is slightly more restrictive than the actual minimum
+ *      (iwlen >= pfree), but AMD_2 will be very slow with no elbow room.
+ *      Thus, this routine enforces a bare minimum elbow room of size n.
+ *
+ * pfree: On input the tail end of the array, Iw [pfree..iwlen-1], is empty,
+ *      and the matrix is stored in Iw [0..pfree-1].  During execution,
+ *      additional data is placed in Iw, and pfree is modified so that
+ *      Iw [pfree..iwlen-1] is always the unused part of Iw.
+ *
+ * Control:  A double array of size AMD_CONTROL containing input parameters
+ *      that affect how the ordering is computed.  If NULL, then default
+ *      settings are used.
+ *
+ *      Control [AMD_DENSE] is used to determine whether or not a given input
+ *      row is "dense".  A row is "dense" if the number of entries in the row
+ *      exceeds Control [AMD_DENSE] times sqrt (n), except that rows with 16 or
+ *      fewer entries are never considered "dense".  To turn off the detection
+ *      of dense rows, set Control [AMD_DENSE] to a negative number, or to a
+ *      number larger than sqrt (n).  The default value of Control [AMD_DENSE]
+ *      is AMD_DEFAULT_DENSE, which is defined in amd.h as 10.
+ *
+ *      Control [AMD_AGGRESSIVE] is used to determine whether or not aggressive
+ *      absorption is to be performed.  If nonzero, then aggressive absorption
+ *      is performed (this is the default).
+
+ * ----------------------------------------------------------------------------
+ * INPUT/OUPUT ARGUMENTS:
+ * ----------------------------------------------------------------------------
+ *
+ * Pe:  An integer array of size n.  On input, Pe [i] is the index in Iw of
+ *      the start of row i.  Pe [i] is ignored if row i has no off-diagonal
+ *      entries.  Thus Pe [i] must be in the range 0 to pfree-1 for non-empty
+ *      rows.
+ *
+ *      During execution, it is used for both supervariables and elements:
+ *
+ *      Principal supervariable i:  index into Iw of the description of
+ *          supervariable i.  A supervariable represents one or more rows of
+ *          the matrix with identical nonzero pattern.  In this case,
+ *          Pe [i] >= 0.
+ *
+ *      Non-principal supervariable i:  if i has been absorbed into another
+ *          supervariable j, then Pe [i] = FLIP (j), where FLIP (j) is defined
+ *          as (-(j)-2).  Row j has the same pattern as row i.  Note that j
+ *          might later be absorbed into another supervariable j2, in which
+ *          case Pe [i] is still FLIP (j), and Pe [j] = FLIP (j2) which is
+ *          < EMPTY, where EMPTY is defined as (-1) in amd_internal.h.
+ *
+ *      Unabsorbed element e:  the index into Iw of the description of element
+ *          e, if e has not yet been absorbed by a subsequent element.  Element
+ *          e is created when the supervariable of the same name is selected as
+ *          the pivot.  In this case, Pe [i] >= 0.
+ *
+ *      Absorbed element e:  if element e is absorbed into element e2, then
+ *          Pe [e] = FLIP (e2).  This occurs when the pattern of e (which we
+ *          refer to as Le) is found to be a subset of the pattern of e2 (that
+ *          is, Le2).  In this case, Pe [i] < EMPTY.  If element e is "null"
+ *          (it has no nonzeros outside its pivot block), then Pe [e] = EMPTY,
+ *          and e is the root of an assembly subtree (or the whole tree if
+ *          there is just one such root).
+ *
+ *      Dense variable i:  if i is "dense", then Pe [i] = EMPTY.
+ *
+ *      On output, Pe holds the assembly tree/forest, which implicitly
+ *      represents a pivot order with identical fill-in as the actual order
+ *      (via a depth-first search of the tree), as follows.  If Nv [i] > 0,
+ *      then i represents a node in the assembly tree, and the parent of i is
+ *      Pe [i], or EMPTY if i is a root.  If Nv [i] = 0, then (i, Pe [i])
+ *      represents an edge in a subtree, the root of which is a node in the
+ *      assembly tree.  Note that i refers to a row/column in the original
+ *      matrix, not the permuted matrix.
+ *
+ * Info:  A double array of size AMD_INFO.  If present, (that is, not NULL),
+ *      then statistics about the ordering are returned in the Info array.
+ *      See amd.h for a description.
+
+ * ----------------------------------------------------------------------------
+ * INPUT/MODIFIED (undefined on output):
+ * ----------------------------------------------------------------------------
+ *
+ * Len:  An integer array of size n.  On input, Len [i] holds the number of
+ *      entries in row i of the matrix, excluding the diagonal.  The contents
+ *      of Len are undefined on output.
+ *
+ * Iw:  An integer array of size iwlen.  On input, Iw [0..pfree-1] holds the
+ *      description of each row i in the matrix.  The matrix must be symmetric,
+ *      and both upper and lower triangular parts must be present.  The
+ *      diagonal must not be present.  Row i is held as follows:
+ *
+ *          Len [i]:  the length of the row i data structure in the Iw array.
+ *          Iw [Pe [i] ... Pe [i] + Len [i] - 1]:
+ *              the list of column indices for nonzeros in row i (simple
+ *              supervariables), excluding the diagonal.  All supervariables
+ *              start with one row/column each (supervariable i is just row i).
+ *              If Len [i] is zero on input, then Pe [i] is ignored on input.
+ *
+ *          Note that the rows need not be in any particular order, and there
+ *          may be empty space between the rows.
+ *
+ *      During execution, the supervariable i experiences fill-in.  This is
+ *      represented by placing in i a list of the elements that cause fill-in
+ *      in supervariable i:
+ *
+ *          Len [i]:  the length of supervariable i in the Iw array.
+ *          Iw [Pe [i] ... Pe [i] + Elen [i] - 1]:
+ *              the list of elements that contain i.  This list is kept short
+ *              by removing absorbed elements.
+ *          Iw [Pe [i] + Elen [i] ... Pe [i] + Len [i] - 1]:
+ *              the list of supervariables in i.  This list is kept short by
+ *              removing nonprincipal variables, and any entry j that is also
+ *              contained in at least one of the elements (j in Le) in the list
+ *              for i (e in row i).
+ *
+ *      When supervariable i is selected as pivot, we create an element e of
+ *      the same name (e=i):
+ *
+ *          Len [e]:  the length of element e in the Iw array.
+ *          Iw [Pe [e] ... Pe [e] + Len [e] - 1]:
+ *              the list of supervariables in element e.
+ *
+ *      An element represents the fill-in that occurs when supervariable i is
+ *      selected as pivot (which represents the selection of row i and all
+ *      non-principal variables whose principal variable is i).  We use the
+ *      term Le to denote the set of all supervariables in element e.  Absorbed
+ *      supervariables and elements are pruned from these lists when
+ *      computationally convenient.
+ *
+ *  CAUTION:  THE INPUT MATRIX IS OVERWRITTEN DURING COMPUTATION.
+ *  The contents of Iw are undefined on output.
+
+ * ----------------------------------------------------------------------------
+ * OUTPUT (need not be set on input):
+ * ----------------------------------------------------------------------------
+ *
+ * Nv:  An integer array of size n.  During execution, ABS (Nv [i]) is equal to
+ *      the number of rows that are represented by the principal supervariable
+ *      i.  If i is a nonprincipal or dense variable, then Nv [i] = 0.
+ *      Initially, Nv [i] = 1 for all i.  Nv [i] < 0 signifies that i is a
+ *      principal variable in the pattern Lme of the current pivot element me.
+ *      After element me is constructed, Nv [i] is set back to a positive
+ *      value.
+ *
+ *      On output, Nv [i] holds the number of pivots represented by super
+ *      row/column i of the original matrix, or Nv [i] = 0 for non-principal
+ *      rows/columns.  Note that i refers to a row/column in the original
+ *      matrix, not the permuted matrix.
+ *
+ * Elen:  An integer array of size n.  See the description of Iw above.  At the
+ *      start of execution, Elen [i] is set to zero for all rows i.  During
+ *      execution, Elen [i] is the number of elements in the list for
+ *      supervariable i.  When e becomes an element, Elen [e] = FLIP (esize) is
+ *      set, where esize is the size of the element (the number of pivots, plus
+ *      the number of nonpivotal entries).  Thus Elen [e] < EMPTY.
+ *      Elen (i) = EMPTY set when variable i becomes nonprincipal.
+ *
+ *      For variables, Elen (i) >= EMPTY holds until just before the
+ *      postordering and permutation vectors are computed.  For elements,
+ *      Elen [e] < EMPTY holds.
+ *
+ *      On output, Elen [i] is the degree of the row/column in the Cholesky
+ *      factorization of the permuted matrix, corresponding to the original row
+ *      i, if i is a super row/column.  It is equal to EMPTY if i is
+ *      non-principal.  Note that i refers to a row/column in the original
+ *      matrix, not the permuted matrix.
+ *
+ *      Note that the contents of Elen on output differ from the Fortran
+ *      version (Elen holds the inverse permutation in the Fortran version,
+ *      which is instead returned in the Next array in this C version,
+ *      described below).
+ *
+ * Last: In a degree list, Last [i] is the supervariable preceding i, or EMPTY
+ *      if i is the head of the list.  In a hash bucket, Last [i] is the hash
+ *      key for i.
+ *
+ *      Last [Head [hash]] is also used as the head of a hash bucket if
+ *      Head [hash] contains a degree list (see the description of Head,
+ *      below).
+ *
+ *      On output, Last [0..n-1] holds the permutation.  That is, if
+ *      i = Last [k], then row i is the kth pivot row (where k ranges from 0 to
+ *      n-1).  Row Last [k] of A is the kth row in the permuted matrix, PAP'.
+ *
+ * Next: Next [i] is the supervariable following i in a link list, or EMPTY if
+ *      i is the last in the list.  Used for two kinds of lists:  degree lists
+ *      and hash buckets (a supervariable can be in only one kind of list at a
+ *      time).
+ *
+ *      On output Next [0..n-1] holds the inverse permutation.  That is, if
+ *      k = Next [i], then row i is the kth pivot row. Row i of A appears as
+ *      the (Next[i])-th row in the permuted matrix, PAP'.
+ *
+ *      Note that the contents of Next on output differ from the Fortran
+ *      version (Next is undefined on output in the Fortran version).
+
+ * ----------------------------------------------------------------------------
+ * LOCAL WORKSPACE (not input or output - used only during execution):
+ * ----------------------------------------------------------------------------
+ *
+ * Degree:  An integer array of size n.  If i is a supervariable, then
+ *      Degree [i] holds the current approximation of the external degree of
+ *      row i (an upper bound).  The external degree is the number of nonzeros
+ *      in row i, minus ABS (Nv [i]), the diagonal part.  The bound is equal to
+ *      the exact external degree if Elen [i] is less than or equal to two.
+ *
+ *      We also use the term "external degree" for elements e to refer to
+ *      |Le \ Lme|.  If e is an element, then Degree [e] is |Le|, which is the
+ *      degree of the off-diagonal part of the element e (not including the
+ *      diagonal part).
+ *
+ * Head:   An integer array of size n.  Head is used for degree lists.
+ *      Head [deg] is the first supervariable in a degree list.  All
+ *      supervariables i in a degree list Head [deg] have the same approximate
+ *      degree, namely, deg = Degree [i].  If the list Head [deg] is empty then
+ *      Head [deg] = EMPTY.
+ *
+ *      During supervariable detection Head [hash] also serves as a pointer to
+ *      a hash bucket.  If Head [hash] >= 0, there is a degree list of degree
+ *      hash.  The hash bucket head pointer is Last [Head [hash]].  If
+ *      Head [hash] = EMPTY, then the degree list and hash bucket are both
+ *      empty.  If Head [hash] < EMPTY, then the degree list is empty, and
+ *      FLIP (Head [hash]) is the head of the hash bucket.  After supervariable
+ *      detection is complete, all hash buckets are empty, and the
+ *      (Last [Head [hash]] = EMPTY) condition is restored for the non-empty
+ *      degree lists.
+ *
+ * W:  An integer array of size n.  The flag array W determines the status of
+ *      elements and variables, and the external degree of elements.
+ *
+ *      for elements:
+ *          if W [e] = 0, then the element e is absorbed.
+ *          if W [e] >= wflg, then W [e] - wflg is the size of the set
+ *              |Le \ Lme|, in terms of nonzeros (the sum of ABS (Nv [i]) for
+ *              each principal variable i that is both in the pattern of
+ *              element e and NOT in the pattern of the current pivot element,
+ *              me).
+ *          if wflg > W [e] > 0, then e is not absorbed and has not yet been
+ *              seen in the scan of the element lists in the computation of
+ *              |Le\Lme| in Scan 1 below.
+ *
+ *      for variables:
+ *          during supervariable detection, if W [j] != wflg then j is
+ *          not in the pattern of variable i.
+ *
+ *      The W array is initialized by setting W [i] = 1 for all i, and by
+ *      setting wflg = 2.  It is reinitialized if wflg becomes too large (to
+ *      ensure that wflg+n does not cause integer overflow).

+*  glp_asnprob_hall - find bipartite matching of maximum cardinality
+*
+*  SYNOPSIS
+*
+*  int glp_asnprob_hall(glp_graph *G, int v_set, int a_x);
+*
+*  DESCRIPTION
+*
+*  The routine glp_asnprob_hall finds a matching of maximal cardinality
+*  in the specified bipartite graph G. It uses a version of the Fortran
+*  routine MC21A developed by I.S.Duff [1], which implements Hall's
+*  algorithm [2].
+*
+*  RETURNS
+*
+*  The routine glp_asnprob_hall returns the cardinality of the matching
+*  found. However, if the specified graph is incorrect (as detected by
+*  the routine glp_check_asnprob), the routine returns negative value.

+*  The routine glp_read_lp reads problem data in CPLEX LP format from

+*
+*  The parameter parm is a pointer to the structure glp_cpxcp, which
+*  specifies control parameters used by the routine. If parm is NULL,
+*  the routine uses default settings.
+*
+*  The character string fname specifies a name of the text file to be

+*
+*  Note that before reading data the current content of the problem
+*  object is completely erased with the routine glp_erase_prob.
+*
+*  RETURNS
+*
+*  If the operation was successful, the routine glp_read_lp returns

+*
+*  SYNOPSIS
+*
+*  int glp_write_lp(glp_prob *P, const glp_cpxcp *parm, const char
+*     *fname);
+*
+*  DESCRIPTION
+*
+*  The routine glp_write_lp writes problem data in CPLEX LP format to
+*  a text file.
+*
+*  The parameter parm is a pointer to the structure glp_cpxcp, which
+*  specifies control parameters used by the routine. If parm is NULL,
+*  the routine uses default settings.
+*
+*  The character string fname specifies a name of the text file to be
+*  written.
+*
+*  RETURNS
+*
+*  If the operation was successful, the routine glp_write_lp returns
+*  zero. Otherwise, it prints an error message and returns non-zero. */

+*
+*  glp_cpp - solve critical path problem
+*
+*  SYNOPSIS
+*
+*  double glp_cpp(glp_graph *G, int v_t, int v_es, int v_ls);
+*
+*  DESCRIPTION
+*
+*  The routine glp_cpp solves the critical path problem represented in
+*  the form of the project network.
+*
+*  The parameter G is a pointer to the graph object, which specifies
+*  the project network. This graph must be acyclic. Multiple arcs are
+*  allowed being considered as single arcs.
+*
+*  The parameter v_t specifies an offset of the field of type double
+*  in the vertex data block, which contains time t[i] >= 0 needed to
+*  perform corresponding job j. If v_t < 0, it is assumed that t[i] = 1
+*  for all jobs.
+*
+*  The parameter v_es specifies an offset of the field of type double
+*  in the vertex data block, to which the routine stores earliest start
+*  time for corresponding job. If v_es < 0, this time is not stored.
+*
+*  The parameter v_ls specifies an offset of the field of type double
+*  in the vertex data block, to which the routine stores latest start
+*  time for corresponding job. If v_ls < 0, this time is not stored.
+*
+*  RETURNS
+*
+*  The routine glp_cpp returns the minimal project duration, that is,
+*  minimal time needed to perform all jobs in the project. */

+*  NAME
+*
+*  glp_gridgen - grid-like network problem generator
+*
+*  SYNOPSIS
+*
+*  int glp_gridgen(glp_graph *G, int v_rhs, int a_cap, int a_cost,
+*     const int parm[1+14]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_gridgen is a grid-like network problem generator
+*  developed by Yusin Lee and Jim Orlin.
+*
+*  The parameter G specifies the graph object, to which the generated
+*  problem data have to be stored. Note that on entry the graph object
+*  is erased with the routine glp_erase_graph.
+*
+*  The parameter v_rhs specifies an offset of the field of type double
+*  in the vertex data block, to which the routine stores the supply or
+*  demand value. If v_rhs < 0, the value is not stored.
+*
+*  The parameter a_cap specifies an offset of the field of type double
+*  in the arc data block, to which the routine stores the arc capacity.
+*  If a_cap < 0, the capacity is not stored.
+*
+*  The parameter a_cost specifies an offset of the field of type double
+*  in the arc data block, to which the routine stores the per-unit cost
+*  if the arc flow. If a_cost < 0, the cost is not stored.
+*
+*  The array parm contains description of the network to be generated:
+*
+*  parm[0]  not used
+*  parm[1]  two-ways arcs indicator:
+*           1 - if links in both direction should be generated
+*           0 - otherwise
+*  parm[2]  random number seed (a positive integer)
+*  parm[3]  number of nodes (the number of nodes generated might be
+*           slightly different to make the network a grid)
+*  parm[4]  grid width
+*  parm[5]  number of sources
+*  parm[6]  number of sinks
+*  parm[7]  average degree
+*  parm[8]  total flow
+*  parm[9]  distribution of arc costs:
+*           1 - uniform
+*           2 - exponential
+*  parm[10] lower bound for arc cost (uniform)
+*           100 * lambda (exponential)
+*  parm[11] upper bound for arc cost (uniform)
+*           not used (exponential)
+*  parm[12] distribution of arc capacities:
+*           1 - uniform
+*           2 - exponential
+*  parm[13] lower bound for arc capacity (uniform)
+*           100 * lambda (exponential)
+*  parm[14] upper bound for arc capacity (uniform)
+*           not used (exponential)
+*
+*  RETURNS
+*
+*  If the instance was successfully generated, the routine glp_gridgen
+*  returns zero; otherwise, if specified parameters are inconsistent,
+*  the routine returns a non-zero error code.
+*
+*  COMMENTS
+*
+*  This network generator generates a grid-like network plus a super
+*  node. In additional to the arcs connecting the nodes in the grid,
+*  there is an arc from each supply node to the super node and from the
+*  super node to each demand node to guarantee feasiblity. These arcs
+*  have very high costs and very big capacities.
+*
+*  The idea of this network generator is as follows: First, a grid of
+*  n1 * n2 is generated. For example, 5 * 3. The nodes are numbered as
+*  1 to 15, and the supernode is numbered as n1*n2+1. Then arcs between
+*  adjacent nodes are generated. For these arcs, the user is allowed to
+*  specify either to generate two-way arcs or one-way arcs. If two-way
+*  arcs are to be generated, two arcs, one in each direction, will be
+*  generated between each adjacent node pairs. Otherwise, only one arc
+*  will be generated. If this is the case, the arcs will be generated
+*  in alterntive directions as shown below.
+*
+*      1 ---> 2 ---> 3 ---> 4 ---> 5
+*      |      ^      |      ^      |
+*      |      |      |      |      |
+*      V      |      V      |      V
+*      6 <--- 7 <--- 8 <--- 9 <--- 10
+*      |      ^      |      ^      |
+*      |      |      |      |      |
+*      V      |      V      |      V
+*     11 --->12 --->13 --->14 ---> 15
+*
+*  Then the arcs between the super node and the source/sink nodes are
+*  added as mentioned before. If the number of arcs still doesn't reach
+*  the requirement, additional arcs will be added by uniformly picking
+*  random node pairs. There is no checking to prevent multiple arcs
+*  between any pair of nodes. However, there will be no self-arcs (arcs
+*  that poins back to its tail node) in the network.
+*
+*  The source and sink nodes are selected uniformly in the network, and
+*  the imbalances of each source/sink node are also assigned by uniform
+*  distribution. */

+*  SYNOPSIS
+*
+*  int glp_read_mps(glp_prob *P, int fmt, const glp_mpscp *parm,
+*     const char *fname);
+*
+*  DESCRIPTION
+*
+*  The routine glp_read_mps reads problem data in MPS format from a
+*  text file.
+*
+*  The parameter fmt specifies the version of MPS format:
+*
+*  GLP_MPS_DECK - fixed (ancient) MPS format;
+*  GLP_MPS_FILE - free (modern) MPS format.
+*
+*  The parameter parm is a pointer to the structure glp_mpscp, which
+*  specifies control parameters used by the routine. If parm is NULL,
+*  the routine uses default settings.
+*
+*  The character string fname specifies a name of the text file to be
+*  read.
+*
+*  Note that before reading data the current content of the problem
+*  object is completely erased with the routine glp_erase_prob.
+*
+*  RETURNS
+*
+*  If the operation was successful, the routine glp_read_mps returns
+*  zero. Otherwise, it prints an error message and returns non-zero. */

+*  NAME
+*
+*  glp_write_mps - write problem data in MPS format
+*
+*  SYNOPSIS
+*
+*  int glp_write_mps(glp_prob *P, int fmt, const glp_mpscp *parm,
+*     const char *fname);
+*
+*  DESCRIPTION
+*
+*  The routine glp_write_mps writes problem data in MPS format to a
+*  text file.
+*
+*  The parameter fmt specifies the version of MPS format:
+*
+*  GLP_MPS_DECK - fixed (ancient) MPS format;
+*  GLP_MPS_FILE - free (modern) MPS format.
+*
+*  The parameter parm is a pointer to the structure glp_mpscp, which
+*  specifies control parameters used by the routine. If parm is NULL,
+*  the routine uses default settings.
+*
+*  The character string fname specifies a name of the text file to be
+*  written.
+*
+*  RETURNS
+*
+*  If the operation was successful, the routine glp_read_mps returns
+*  zero. Otherwise, it prints an error message and returns non-zero. */

+*  NAME
+*
+*  glp_netgen - Klingman's network problem generator
+*
+*  SYNOPSIS
+*
+*  int glp_netgen(glp_graph *G, int v_rhs, int a_cap, int a_cost,
+*     const int parm[1+15]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_netgen is a network problem generator developed by
+*  Dr. Darwin Klingman. It can create capacitated and uncapacitated
+*  minimum cost flow (or transshipment), transportation, and assignment
+*  problems.
+*
+*  The parameter G specifies the graph object, to which the generated
+*  problem data have to be stored. Note that on entry the graph object
+*  is erased with the routine glp_erase_graph.
+*
+*  The parameter v_rhs specifies an offset of the field of type double
+*  in the vertex data block, to which the routine stores the supply or
+*  demand value. If v_rhs < 0, the value is not stored.
+*
+*  The parameter a_cap specifies an offset of the field of type double
+*  in the arc data block, to which the routine stores the arc capacity.
+*  If a_cap < 0, the capacity is not stored.
+*
+*  The parameter a_cost specifies an offset of the field of type double
+*  in the arc data block, to which the routine stores the per-unit cost
+*  if the arc flow. If a_cost < 0, the cost is not stored.
+*
+*  The array parm contains description of the network to be generated:
+*
+*  parm[0]           not used
+*  parm[1]  (iseed)  8-digit positive random number seed
+*  parm[2]  (nprob)  8-digit problem id number
+*  parm[3]  (nodes)  total number of nodes
+*  parm[4]  (nsorc)  total number of source nodes (including
+*                    transshipment nodes)
+*  parm[5]  (nsink)  total number of sink nodes (including
+*                    transshipment nodes)
+*  parm[6]  (iarcs)  number of arcs
+*  parm[7]  (mincst) minimum cost for arcs
+*  parm[8]  (maxcst) maximum cost for arcs
+*  parm[9]  (itsup)  total supply
+*  parm[10] (ntsorc) number of transshipment source nodes
+*  parm[11] (ntsink) number of transshipment sink nodes
+*  parm[12] (iphic)  percentage of skeleton arcs to be given
+*                    the maximum cost
+*  parm[13] (ipcap)  percentage of arcs to be capacitated
+*  parm[14] (mincap) minimum upper bound for capacitated arcs
+*  parm[15] (maxcap) maximum upper bound for capacitated arcs
+*
+*  The routine generates a transportation problem if:
+*
+*     nsorc + nsink = nodes, ntsorc = 0, and ntsink = 0.
+*
+*  The routine generates an assignment problem if the requirements for
+*  a transportation problem are met and:
+*
+*     nsorc = nsink and itsup = nsorc.
+*
+*  RETURNS
+*
+*  If the instance was successfully generated, the routine glp_netgen
+*  returns zero; otherwise, if specified parameters are inconsistent,
+*  the routine returns a non-zero error code.

+*
+*  SYNOPSIS
+*
+*  int glp_check_dup(int m, int n, int ne, const int ia[],
+*     const int ja[]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_check_dup checks for duplicate elements (that is,
+*  elements with identical indices) in a sparse matrix specified in the
+*  coordinate format.
+*
+*  The parameters m and n specifies, respectively, the number of rows
+*  and columns in the matrix, m >= 0, n >= 0.
+*
+*  The parameter ne specifies the number of (structurally) non-zero
+*  elements in the matrix, ne >= 0.
+*
+*  Elements of the matrix are specified as doublets (ia[k],ja[k]) for
+*  k = 1,...,ne, where ia[k] is a row index, ja[k] is a column index.
+*
+*  The routine glp_check_dup can be used prior to a call to the routine
+*  glp_load_matrix to check that the constraint matrix to be loaded has
+*  no duplicate elements.
+*
+*  RETURNS
+*
+*  The routine glp_check_dup returns one of the following values:
+*
+*   0 - the matrix has no duplicate elements;
+*
+*  -k - indices ia[k] or/and ja[k] are out of range;
+*
+*  +k - element (ia[k],ja[k]) is duplicate. */

+*  NAME
+*
+*  glp_rmfgen - Goldfarb's maximum flow problem generator
+*
+*  SYNOPSIS
+*
+*  int glp_rmfgen(glp_graph *G, int *s, int *t, int a_cap,
+*     const int parm[1+5]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_rmfgen is a maximum flow problem generator developed
+*  by D.Goldfarb and M.Grigoriadis.
+*
+*  The parameter G specifies the graph object, to which the generated
+*  problem data have to be stored. Note that on entry the graph object
+*  is erased with the routine glp_erase_graph.
+*
+*  The pointer s specifies a location, to which the routine stores the
+*  source node number. If s is NULL, the node number is not stored.
+*
+*  The pointer t specifies a location, to which the routine stores the
+*  sink node number. If t is NULL, the node number is not stored.
+*
+*  The parameter a_cap specifies an offset of the field of type double
+*  in the arc data block, to which the routine stores the arc capacity.
+*  If a_cap < 0, the capacity is not stored.
+*
+*  The array parm contains description of the network to be generated:
+*
+*  parm[0]  not used
+*  parm[1]  (seed)   random number seed (a positive integer)
+*  parm[2]  (a)      frame size
+*  parm[3]  (b)      depth
+*  parm[4]  (c1)     minimal arc capacity
+*  parm[5]  (c2)     maximal arc capacity
+*
+*  RETURNS
+*
+*  If the instance was successfully generated, the routine glp_netgen
+*  returns zero; otherwise, if specified parameters are inconsistent,
+*  the routine returns a non-zero error code.
+*
+*  COMMENTS
+*
+*  The generated network is as follows. It has b pieces of frames of
+*  size a * a. (So alltogether the number of vertices is a * a * b)
+*
+*  In each frame all the vertices are connected with their neighbours
+*  (forth and back). In addition the vertices of a frame are connected
+*  one to one with the vertices of next frame using a random permutation
+*  of those vertices.
+*
+*  The source is the lower left vertex of the first frame, the sink is
+*  the upper right vertex of the b'th frame.

+*
+*  The routine glp_top_sort performs topological sorting of vertices of

+*
+*  The parameter v_num specifies an offset of the field of type int in

+*  assigned. If v_num < 0, vertex numbers are not stored.
+*
+*  The vertices are numbered from 1 to n, where n is the total number
+*  of vertices in the graph. The vertex numbering has the property that
+*  for every arc (i->j) in the graph the condition num(i) < num(j)
+*  holds. Special case num(i) = 0 means that vertex i is not assigned a
+*  number, because the graph is *not* acyclic.
+*
+*  RETURNS
+*
+*  If the graph is acyclic and therefore all the vertices have been
+*  assigned numbers, the routine glp_top_sort returns zero. Otherwise,
+*  if the graph is not acyclic, the routine returns the number of
+*  vertices which have not been numbered, i.e. for which num(i) = 0. */

+*
+*  SYNOPSIS
+*
+*  int glp_weak_comp(glp_graph *G, int v_num);
+*
+*  DESCRIPTION
+*
+*  The routine glp_weak_comp finds all weakly connected components of
+*  the specified graph.
+*
+*  The parameter v_num specifies an offset of the field of type int
+*  in the vertex data block, to which the routine stores the number of
+*  a (weakly) connected component containing that vertex. If v_num < 0,
+*  no component numbers are stored.
+*
+*  The components are numbered in arbitrary order from 1 to nc, where
+*  nc is the total number of components found, 0 <= nc <= |V|.
+*
+*  RETURNS
+*
+*  The routine returns nc, the total number of components found. */

+/***********************************************************************
+*  The structure BTF describes BT-factorization, which is sparse block
+*  triangular LU-factorization.
+*
+*  The BT-factorization has the following format:
+*
+*     A = P * A~ * Q,                                                (1)
+*
+*  where A is a given (unsymmetric) square matrix, A~ is an upper block
+*  triangular matrix (see below), P and Q are permutation matrices. All
+*  the matrices have the same order n.
+*
+*  The matrix A~, which is a permuted version of the original matrix A,
+*  has the following structure:
+*
+*     A~[1,1]  A~[1,2]  ...  A~[1,num-1]      A~[1,num]
+*
+*              A~[2,2]  ...  A~[2,num-1]      A~[2,num]
+*
+*                       . . . . . . . . .                            (2)
+*
+*                        A~[num-1,num-1]  A~[num-1,num]
+*
+*                                           A~[num,num]
+*
+*  where A~[i,j] is a submatrix called a "block," num is the number of
+*  blocks. Each diagonal block A~[k,k] is a non-singular square matrix,
+*  and each subdiagonal block A~[i,j], i > j, is a zero submatrix, thus
+*  A~ is an upper block triangular matrix.
+*
+*  Permutation matrices P and Q are stored in ordinary arrays in both
+*  row- and column-like formats.
+*
+*  The original matrix A is stored in both row- and column-wise sparse
+*  formats in the associated sparse vector area (SVA). Should note that
+*  elements of all diagonal blocks A~[k,k] in matrix A are set to zero
+*  (i.e. removed), so only elements of non-diagonal blocks are stored.
+*
+*  Each diagonal block A~[k,k], 1 <= k <= num, is stored in the form of
+*  LU-factorization (see the module LUF). */

+*  fhv_ft_update - update FHV-factorization (Forrest-Tomlin)
+*
+*  This routine updates FHV-factorization of the original matrix A
+*  after replacing its j-th column by a new one. The routine is based
+*  on the method proposed by Forrest and Tomlin [1].
+*
+*  The parameter q specifies the number of column of A, which has been
+*  replaced, 1 <= q <= n, where n is the order of A.
+*
+*  Row indices and numerical values of non-zero elements of the new
+*  j-th column of A should be placed in locations aq_ind[1], ...,
+*  aq_ind[aq_len] and aq_val[1], ..., aq_val[aq_len], respectively,
+*  where aq_len is the number of non-zeros. Neither zero nor duplicate
+*  elements are allowed.
+*
+*  The working arrays ind, val, and work should have at least 1+n
+*  elements (0-th elements are not used).
+*
+*  RETURNS
+*
+*  0  The factorization has been successfully updated.
+*
+*  1  New matrix U = P'* V * Q' is upper triangular with zero diagonal
+*     element u[s,s]. (Elimination was not performed.)
+*
+*  2  New matrix U = P'* V * Q' is upper triangular, and its diagonal
+*     element u[s,s] or u[t,t] is too small in magnitude. (Elimination
+*     was not performed.)
+*
+*  3  The same as 2, but after performing elimination.
+*
+*  4  The factorization has not been updated, because maximal number of
+*     updates has been reached.
+*
+*  5  Accuracy test failed for the updated factorization.
+*
+*  BACKGROUND
+*
+*  The routine is based on the updating method proposed by Forrest and
+*  Tomlin [1].
+*
+*  Let q-th column of the original matrix A have been replaced by new
+*  column A[q]. Then, to keep the equality A = F * H * V, q-th column
+*  of matrix V should be replaced by column V[q] = inv(F * H) * A[q].
+*  From the standpoint of matrix U = P'* V * Q' such replacement is
+*  equivalent to replacement of s-th column of matrix U, where s is
+*  determined from q by permutation matrix Q. Thus, matrix U loses its
+*  upper triangular form and becomes the following:
+*
+*        1   s       t   n
+*     1  x x * x x x x x x
+*        . x * x x x x x x
+*     s  . . * x x x x x x
+*        . . * x x x x x x
+*        . . * . x x x x x
+*        . . * . . x x x x
+*     t  . . * . . . x x x
+*        . . . . . . . x x
+*     n  . . . . . . . . x
+*
+*  where t is largest row index of a non-zero element in s-th column.
+*
+*  The routine makes matrix U upper triangular as follows. First, it
+*  moves rows and columns s+1, ..., t by one position to the left and
+*  upwards, resp., and moves s-th row and s-th column to position t.
+*  Due to such symmetric permutations matrix U becomes the following
+*  (note that all diagonal elements remain on the diagonal, and element
+*  u[s,s] becomes u[t,t]):
+*
+*        1   s       t   n
+*     1  x x x x x x * x x
+*        . x x x x x * x x
+*     s  . . x x x x * x x
+*        . . . x x x * x x
+*        . . . . x x * x x
+*        . . . . . x * x x
+*     t  . . x x x x * x x
+*        . . . . . . . x x
+*     n  . . . . . . . . x
+*
+*  Then the routine performs gaussian elimination to eliminate
+*  subdiagonal elements u[t,s], ..., u[t,t-1] using diagonal elements
+*  u[s,s], ..., u[t-1,t-1] as pivots. During the elimination process
+*  the routine permutes neither rows nor columns, so only t-th row is
+*  changed. Should note that actually all operations are performed on
+*  matrix V = P * U * Q, since matrix U is not stored.
+*
+*  To keep the equality A = F * H * V, the routine appends new row-like
+*  factor H[k] to matrix H, and every time it applies elementary
+*  gaussian transformation to eliminate u[t,j'] = v[p,j] using pivot
+*  u[j',j'] = v[i,j], it also adds new element f[p,j] = v[p,j] / v[i,j]
+*  (gaussian multiplier) to factor H[k], which initially is a unity
+*  matrix. At the end of elimination process the row-like factor H[k]
+*  may look as follows:
+*
+*        1               n          1   s       t   n
+*     1  1 . . . . . . . .       1  1 . . . . . . . .
+*        . 1 . . . . . . .          . 1 . . . . . . .
+*        . . 1 . . . . . .       s  . . 1 . . . . . .
+*     p  . x x 1 . x . x .          . . . 1 . . . . .
+*        . . . . 1 . . . .          . . . . 1 . . . .
+*        . . . . . 1 . . .          . . . . . 1 . . .
+*        . . . . . . 1 . .       t  . . x x x x 1 . .
+*        . . . . . . . 1 .          . . . . . . . 1 .

+*
+*              H[k]                 inv(P) * H[k] * P
+*
+*  If, however, s = t, no elimination is needed, in which case no new
+*  row-like factor is created.

+*  The structure LUF describes sparse LU-factorization.
+*
+*  The LU-factorization has the following format:
+*
+*     A = F * V = P * L * U * Q,                                     (1)

+*
+*     V = P * U * Q,                                                 (3)
+*
+*  where A is a given (unsymmetric) square matrix, F and V are matrix
+*  factors actually computed, L is a lower triangular matrix with unity
+*  diagonal, U is an upper triangular matrix, P and Q are permutation
+*  matrices, P' is a matrix transposed to P. All the matrices have the
+*  same order n.
+*
+*  Matrices F and V are stored in both row- and column-wise sparse
+*  formats in the associated sparse vector area (SVA). Unity diagonal
+*  elements of matrix F are not stored. Pivot elements of matrix V
+*  (which correspond to diagonal elements of matrix U) are stored in
+*  a separate ordinary array.
+*
+*  Permutation matrices P and Q are stored in ordinary arrays in both
+*  row- and column-like formats.
+*
+*  Matrices L and U are completely defined by matrices F, V, P, and Q,
+*  and therefore not stored explicitly. */

+*  sgf_reduce_nuc - initial reordering to minimize nucleus size
+*
+*  On entry to this routine it is assumed that V = A and F = P = Q = I,
+*  where A is the original matrix to be factorized. It is also assumed
+*  that matrix V = A is stored in both row- and column-wise formats.
+*
+*  This routine performs (implicit) non-symmetric permutations of rows
+*  and columns of matrix U = P'* V * Q' to reduce it to the form:
+*
+*        1     k1    k2    n
+*     1  x x x x x x x x x x
+*        . x x x x x x x x x
+*        . . x x x x x x x x
+*     k1 . . . * * * * x x x
+*        . . . * * * * x x x
+*        . . . * * * * x x x

+*        . . . . . . . x x x
+*        . . . . . . . . x x
+*     n  . . . . . . . . . x
+*
+*  where non-zeros in rows and columns k1, k1+1, ..., k2 constitute so
+*  called nucleus ('*'), whose size is minimized by the routine.
+*
+*  The numbers k1 and k2 are returned by the routine on exit. Usually,
+*  if the nucleus exists, 1 <= k1 < k2 <= n. However, if the resultant
+*  matrix U is upper triangular (has no nucleus), k1 = n+1 and k2 = n.
+*
+*  Note that the routines sgf_choose_pivot and sgf_eliminate perform
+*  exactly the same transformations (by processing row and columns
+*  singletons), so preliminary minimization of the nucleus may not be
+*  used. However, processing row and column singletons by the routines

+*  sgf_singl_phase - compute LU-factorization (singleton phase)
+*
+*  It is assumed that on entry to the routine L = P'* F * P = F = I
+*  and matrix U = P'* V * Q' has the following structure (provided by
+*  the routine sgf_reduce_nuc):
+*
+*        1     k1    k2    n
+*     1  a a a b b b b c c c

+*
+*  First, the routine performs (implicit) symmetric permutations of
+*  rows and columns of matrix U to place them in the following order:
+*
+*     1, 2, ..., k1-1; n, n-1, ..., k2+1; k1, k1+1, ..., k2
+*
+*  This changes the structure of matrix U as follows:
+*
+*        1     k1    k2'   n
+*     1  a a a c c c b b b b

+*     n  . . . d d d * * * *
+*
+*  where k2' = n - k2 + k1.
+*
+*  Then the routine performs elementary gaussian transformations to
+*  eliminate subdiagonal elements in columns k1, ..., k2'-1 of U. The
+*  effect is the same as if the routine sgf_eliminate would be called
+*  for k = 1, ..., k2'-1 using diagonal elements u[k,k] as pivots.
+*
+*  After elimination matrices L and U becomes the following:
+*

+/***********************************************************************
+*  sgf_choose_pivot - choose pivot element v[p,q]
+*
+*  This routine chooses pivot element v[p,q], k <= p, q <= n, in the
+*  active submatrix of matrix V = P * U * Q, where k is the number of
+*  current elimination step, 1 <= k <= n.
+*
+*  It is assumed that on entry to the routine matrix U = P'* V * Q' has
+*  the following partially triangularized form:
+*
+*        1       k         n
+*     1  x x x x x x x x x x
+*        . x x x x x x x x x
+*        . . x x x x x x x x
+*        . . . x x x x x x x
+*     k  . . . . * * * * * *
+*        . . . . * * * * * *
+*        . . . . * * * * * *
+*        . . . . * * * * * *
+*        . . . . * * * * * *
+*     n  . . . . * * * * * *
+*
+*  where rows and columns k, k+1, ..., n belong to the active submatrix
+*  (its elements are marked by '*').
+*
+*  Since the matrix U is not stored, the routine works with the matrix
+*  V = P * U * Q. It is assumed that the row-wise representation
+*  corresponds to the matrix V, but the column-wise representation
+*  corresponds to the active submatrix of the matrix V, i.e. elements,
+*  which are not in the active submatrix, are not included in column
+*  vectors. It is also assumed that each active row of the matrix V is
+*  in the set R[len], where len is the number of non-zeros in the row,
+*  and each active column of the matrix V is in the set C[len], where
+*  len is the number of non-zeros in the column (in the latter case
+*  only elements of the active submatrix are counted; such elements are
+*  marked by '*' on the figure above).
+*
+*  For the reason of numerical stability the routine applies so called
+*  threshold pivoting proposed by J.Reid. It is assumed that an element
+*  v[i,j] can be selected as a pivot candidate if it is not very small
+*  (in magnitude) among other elements in the same row, i.e. if it
+*  satisfies to the stability condition |v[i,j]| >= tol * max|v[i,*]|,
+*  where 0 < tol < 1 is a given tolerance.
+*
+*  In order to keep sparsity of the matrix V the routine uses Markowitz
+*  strategy, trying to choose such element v[p,q], which satisfies to
+*  the stability condition (see above) and has smallest Markowitz cost
+*  (nr[p]-1) * (nc[q]-1), where nr[p] and nc[q] are, resp., numbers of
+*  non-zeros in p-th row and q-th column of the active submatrix.
+*
+*  In order to reduce the search, i.e. not to walk through all elements
+*  of the active submatrix, the routine uses a technique proposed by
+*  I.Duff. This technique is based on using the sets R[len] and C[len]
+*  of active rows and columns.
+*
+*  If the pivot element v[p,q] has been chosen, the routine stores its
+*  indices to locations *p and *q and returns zero. Otherwise, non-zero
+*  is returned. */

+*  sgf_eliminate - perform gaussian elimination
+*
+*  This routine performs elementary gaussian transformations in order
+*  to eliminate subdiagonal elements in k-th column of matrix
+*  U = P'* V * Q' using pivot element u[k,k], where k is the number of
+*  current elimination step, 1 <= k <= n.
+*
+*  The parameters p and q specify, resp., row and column indices of the
+*  pivot element v[p,q] = u[k,k].
+*
+*  On entry the routine assumes that partially triangularized matrices
+*  L = P'* F * P and U = P'* V * Q' have the following structure:
+*
+*        1       k         n       1        k         n
+*     1  1 . . . . . . . . .     1  x x x x x x x x x x

+*
+*             matrix L                   matrix U
+*
+*  where rows and columns k, k+1, ..., n of matrix U constitute the
+*  active submatrix. Elements to be eliminated are marked by '#', and
+*  other elements of the active submatrix are marked by '*'. May note
+*  that each eliminated non-zero element u[i,k] of matrix U gives
+*  corresponding non-zero element l[i,k] of matrix L (marked by '_').
+*
+*  Actually all operations are performed on matrix V. It is assumed
+*  that the row-wise representation corresponds to matrix V, but the
+*  column-wise representation corresponds to the active submatrix of
+*  matrix V (or, more precisely, to its pattern, because only row
+*  indices for columns of the active submatrix are used on this stage).
+*
+*  Let u[k,k] = v[p,q] be the pivot. In order to eliminate subdiagonal
+*  elements u[i',k] = v[i,q], i'= k+1, k+2, ..., n, the routine applies
+*  the following elementary gaussian transformations:
+*
+*     (i-th row of V) := (i-th row of V) - f[i,p] * (p-th row of V),
+*
+*  where f[i,p] = v[i,q] / v[p,q] is a gaussian multiplier stored to
+*  p-th column of matrix F to keep the main equality A = F * V
+*  (corresponding elements l[i',k] of matrix L are marked by '_' on the
+*  figure above).
+*
+*  NOTE: On entry to the routine the working arrays flag and work
+*        should contain zeros. This status is retained by the routine
+*        on exit. */

+*
+*  where L is lower triangular matrix with unit diagonal, U is upper
+*  triangular matrix, P and Q are permutation matrices.
+*
+*  On entry to the routine elements of matrix A = (a[i,j]) should be
+*  placed in the array elements a[0], ..., a[n^2-1] in dense row-wise
+*  format. On exit from the routine matrix A is replaced by factors L
+*  and U as follows:
+*
+*       u[1,1]   u[1,2]  ...  u[1,n-1]   u[1,n]

+*
+*  The unit diagonal elements of L are not stored.

+*  Information on permutations of rows and columns of active submatrix
+*  during factorization is accumulated by the routine as follows. Every
+*  time the routine permutes rows i and i' or columns j and j', it also
+*  permutes elements r[i-1] and r[i'-1] or c[j-1] and c[j'-1], resp.
+*  Thus, on entry to the routine elements r[0], r[1], ..., r[n-1] and
+*  c[0], c[1], ..., c[n-1] should be initialized by some integers that
+*  identify rows and columns of the original matrix A.
+*
+*  If the factorization has been successfully computed, the routine
+*  returns zero. Otherwise, if on k-th elimination step, 1 <= k <= n,
+*  all elements of the active submatrix are close to zero, the routine
+*  returns k, in which case a partial factorization is stored in the

+*  sgf_dense_phase - compute LU-factorization (dense phase)
+*
+*  This routine performs dense phase of computing LU-factorization.
+*
+*  The aim is two-fold. First, the main factorization routine switches
+*  to dense phase when the active submatrix is relatively dense, so
+*  using dense format allows significantly reduces overheads needed to
+*  maintain sparse data structures. And second, that is more important,
+*  on dense phase full pivoting is used (rather than partial pivoting)
+*  that allows improving numerical stability, since round-off errors
+*  tend to increase on last steps of the elimination process.
+*
+*  On entry the routine assumes that elimination steps 1, 2, ..., k-1
+*  have been performed, so partially transformed matrices L = P'* F * P
+*  and U = P'* V * Q' have the following structure:

+*  full pivoting, and then copies non-zero elements of factors L~ and
+*  U~ back to factors L and U (more precisely, to factors F and V).

+/***********************************************************************
+*  Sparse Vector Area (SVA) is a container for sparse vectors. This
+*  program object is used mainly on computing factorization, where the
+*  sparse vectors are rows and columns of sparse matrices.
+*
+*  The SVA storage is a set of locations numbered 1, 2, ..., size,
+*  where size is the size of SVA, which is the total number of
+*  locations currently allocated. Each location is identified by its
+*  pointer p, 1 <= p <= size, and is the pair (ind[p], val[p]), where
+*  ind[p] and val[p] are, respectively, the index and value fields used
+*  to store the index and numeric value of a particular vector element.
+*
+*  Each sparse vector is identified by its reference number k,
+*  1 <= k <= n, where n is the total number of vectors currently stored
+*  in SVA, and defined by the triplet (ptr[k], len[k], cap[k]), where:
+*  ptr[k] is a pointer to the first location of the vector; len[k] is
+*  the vector length, which is the number of its non-zero elements,
+*  len[k] >= 0; and cap[k] is the capacity of the vector, which is the
+*  total number of adjacent locations allocated to that vector,
+*  cap[k] >= len[k]. Thus, non-zero elements of k-th vector are stored
+*  in locations ptr[k], ptr[k]+1, ..., ptr[k]+len[k]-1, and locations
+*  ptr[k]+len[k], ptr[k]+len[k]+1, ..., ptr[k]+cap[k]-1 are reserved.
+*
+*  The SVA storage is divided into three parts as follows:
+*
+*  Locations 1, 2, ..., m_ptr-1 constitute the left (dynamic) part of
+*  SVA. This part is used to store vectors, whose capacity may change.
+*  Note that all vectors stored in the left part are also included in
+*  a doubly linked list, where they are ordered by increasing their
+*  pointers ptr[k] (this list is needed for efficient implementation
+*  of the garbage collector used to defragment the left part of SVA);
+*
+*  Locations m_ptr, m_ptr+1, ..., r_ptr-1 are free and constitute the
+*  middle (free) part of SVA.
+*
+*  Locations r_ptr, r_ptr+1, ..., size constitute the right (static)
+*  part of SVA. This part is used to store vectors, whose capacity is
+*  not changed. */

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>

+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your

+
+Description:
+
+   colamd:  an approximate minimum degree column ordering algorithm,
+            for LU factorization of symmetric or unsymmetric matrices,
+            QR factorization, least squares, interior point methods for
+            linear programming problems, and other related problems.
+
+   symamd:  an approximate minimum degree ordering algorithm for
+            Cholesky factorization of symmetric matrices.
+
+Purpose:
+
+   Colamd computes a permutation Q such that the Cholesky factorization
+   of (AQ)'(AQ) has less fill-in and requires fewer floating point
+   operations than A'A.  This also provides a good ordering for sparse
+   partial pivoting methods, P(AQ) = LU, where Q is computed prior to
+   numerical factorization, and P is computed during numerical
+   factorization via conventional partial pivoting with row
+   interchanges.  Colamd is the column ordering method used in SuperLU,
+   part of the ScaLAPACK library.  It is also available as built-in
+   function in MATLAB Version 6, available from MathWorks, Inc.
+   (http://www.mathworks.com).  This routine can be used in place of
+   colmmd in MATLAB.
+
+   Symamd computes a permutation P of a symmetric matrix A such that
+   the Cholesky factorization of PAP' has less fill-in and requires
+   fewer floating point operations than A.  Symamd constructs a matrix
+   M such that M'M has the same nonzero pattern of A, and then orders
+   the columns of M using colmmd.  The column ordering of M is then
+   returned as the row and column ordering P of A.
+
+Authors:
+
+   The authors of the code itself are Stefan I. Larimore and Timothy A.
+   Davis (davis at cise.ufl.edu), University of Florida.  The algorithm
+   was developed in collaboration with John Gilbert, Xerox PARC, and
+   Esmond Ng, Oak Ridge National Laboratory.

+
+    ----------------------------------------------------------------------------
+    colamd_recommended:
+    ----------------------------------------------------------------------------
+
+        C syntax:
+
+            #include "colamd.h"
+            size_t colamd_recommended (int nnz, int n_row, int n_col) ;
+            size_t colamd_l_recommended (UF_long nnz, UF_long n_row,
+                UF_long n_col) ;
+
+        Purpose:
+
+            Returns recommended value of Alen for use by colamd.  Returns 0
+            if any input argument is negative.  The use of this routine
+            is optional.  Not needed for symamd, which dynamically allocates
+            its own memory.
+
+            Note that in v2.4 and earlier, these routines returned int or long.
+            They now return a value of type size_t.
+
+        Arguments (all input arguments):
+
+            int nnz ;           Number of nonzeros in the matrix A.  This must
+                                be the same value as p [n_col] in the call to
+                                colamd - otherwise you will get a wrong value
+                                of the recommended memory to use.
+
+            int n_row ;         Number of rows in the matrix A.
+
+            int n_col ;         Number of columns in the matrix A.
+
+    ----------------------------------------------------------------------------
+    colamd_set_defaults:
+    ----------------------------------------------------------------------------
+
+        C syntax:
+
+            #include "colamd.h"
+            colamd_set_defaults (double knobs [COLAMD_KNOBS]) ;
+            colamd_l_set_defaults (double knobs [COLAMD_KNOBS]) ;
+
+        Purpose:
+
+            Sets the default parameters.  The use of this routine is optional.
+
+        Arguments:
+
+            double knobs [COLAMD_KNOBS] ;       Output only.
+
+                NOTE: the meaning of the dense row/col knobs has changed in v2.4
+
+                knobs [0] and knobs [1] control dense row and col detection:
+
+                Colamd: rows with more than
+                max (16, knobs [COLAMD_DENSE_ROW] * sqrt (n_col))
+                entries are removed prior to ordering.  Columns with more than
+                max (16, knobs [COLAMD_DENSE_COL] * sqrt (MIN (n_row,n_col)))
+                entries are removed prior to
+                ordering, and placed last in the output column ordering.
+
+                Symamd: uses only knobs [COLAMD_DENSE_ROW], which is knobs [0].
+                Rows and columns with more than
+                max (16, knobs [COLAMD_DENSE_ROW] * sqrt (n))
+                entries are removed prior to ordering, and placed last in the
+                output ordering.
+
+                COLAMD_DENSE_ROW and COLAMD_DENSE_COL are defined as 0 and 1,
+                respectively, in colamd.h.  Default values of these two knobs
+                are both 10.  Currently, only knobs [0] and knobs [1] are
+                used, but future versions may use more knobs.  If so, they will
+                be properly set to their defaults by the future version of
+                colamd_set_defaults, so that the code that calls colamd will

+
+        C syntax:
+
+            #include "colamd.h"
+            int colamd (int n_row, int n_col, int Alen, int *A, int *p,
+                double knobs [COLAMD_KNOBS], int stats [COLAMD_STATS]) ;

+                UF_long stats [COLAMD_STATS]) ;
+
+        Purpose:
+
+            Computes a column ordering (Q) of A such that P(AQ)=LU or
+            (AQ)'AQ=LL' have less fill-in and require fewer floating point
+            operations than factorizing the unpermuted matrix A or A'A,
+            respectively.
+
+        Returns:
+
+            TRUE (1) if successful, FALSE (0) otherwise.
+
+        Arguments:
+
+            int n_row ;         Input argument.
+
+                Number of rows in the matrix A.
+                Restriction:  n_row >= 0.
+                Colamd returns FALSE if n_row is negative.
+
+            int n_col ;         Input argument.
+
+                Number of columns in the matrix A.
+                Restriction:  n_col >= 0.
+                Colamd returns FALSE if n_col is negative.
+
+            int Alen ;          Input argument.
+
+                Restriction (see note):
+                Alen >= 2*nnz + 6*(n_col+1) + 4*(n_row+1) + n_col
+                Colamd returns FALSE if these conditions are not met.
+
+                Note:  this restriction makes an modest assumption regarding
+                the size of the two typedef's structures in colamd.h.
+                We do, however, guarantee that
+
+                        Alen >= colamd_recommended (nnz, n_row, n_col)
+
+                will be sufficient.  Note: the macro version does not check
+                for integer overflow, and thus is not recommended.  Use
+                the colamd_recommended routine instead.
+
+            int A [Alen] ;      Input argument, undefined on output.
+
+                A is an integer array of size Alen.  Alen must be at least as
+                large as the bare minimum value given above, but this is very
+                low, and can result in excessive run time.  For best
+                performance, we recommend that Alen be greater than or equal to
+                colamd_recommended (nnz, n_row, n_col), which adds
+                nnz/5 to the bare minimum value given above.
+
+                On input, the row indices of the entries in column c of the
+                matrix are held in A [(p [c]) ... (p [c+1]-1)].  The row indices
+                in a given column c need not be in ascending order, and
+                duplicate row indices may be be present.  However, colamd will
+                work a little faster if both of these conditions are met
+                (Colamd puts the matrix into this format, if it finds that the
+                the conditions are not met).
+
+                The matrix is 0-based.  That is, rows are in the range 0 to
+                n_row-1, and columns are in the range 0 to n_col-1.  Colamd
+                returns FALSE if any row index is out of range.
+
+                The contents of A are modified during ordering, and are
+                undefined on output.
+
+            int p [n_col+1] ;   Both input and output argument.
+
+                p is an integer array of size n_col+1.  On input, it holds the
+                "pointers" for the column form of the matrix A.  Column c of
+                the matrix A is held in A [(p [c]) ... (p [c+1]-1)].  The first
+                entry, p [0], must be zero, and p [c] <= p [c+1] must hold
+                for all c in the range 0 to n_col-1.  The value p [n_col] is
+                thus the total number of entries in the pattern of the matrix A.
+                Colamd returns FALSE if these conditions are not met.
+
+                On output, if colamd returns TRUE, the array p holds the column
+                permutation (Q, for P(AQ)=LU or (AQ)'(AQ)=LL'), where p [0] is
+                the first column index in the new ordering, and p [n_col-1] is
+                the last.  That is, p [k] = j means that column j of A is the
+                kth pivot column, in AQ, where k is in the range 0 to n_col-1
+                (p [0] = j means that column j of A is the first column in AQ).
+
+                If colamd returns FALSE, then no permutation is returned, and
+                p is undefined on output.

+                                and similarly a column can become "empty" if it

+                                This can be excessively high if Alen is close

+

+                                (unsorted columns or duplicate entries).  Colamd
+                                had to do some extra work to sort the matrix
+                                first and remove duplicate entries, but it
+                                still was able to return a valid permutation
+                                (return value of colamd was TRUE).

+
+            See http://www.cise.ufl.edu/research/sparse/colamd/example.c
+            for a complete example.
+
+            To order the columns of a 5-by-4 matrix with 11 nonzero entries in
+            the following nonzero pattern
+
+                x 0 x 0

+                x x 0 0
+
+            with default knobs and no output statistics, do the following:
+
+                #include "colamd.h"

+                int A [ALEN] = {0, 1, 4, 2, 4, 0, 1, 2, 3, 1, 3} ;

+
+        C syntax:
+
+            #include "colamd.h"
+            int symamd (int n, int *A, int *p, int *perm,
+                double knobs [COLAMD_KNOBS], int stats [COLAMD_STATS],
+                void (*allocate) (size_t, size_t), void (*release) (void *)) ;

+                void (*allocate) (size_t, size_t), void (*release) (void *)) ;
+
+        Purpose:
+
+            The symamd routine computes an ordering P of a symmetric sparse
+            matrix A such that the Cholesky factorization PAP' = LL' remains
+            sparse.  It is based on a column ordering of a matrix M constructed
+            so that the nonzero pattern of M'M is the same as A.  The matrix A
+            is assumed to be symmetric; only the strictly lower triangular part
+            is accessed.  You must pass your selected memory allocator (usually
+            calloc/free or mxCalloc/mxFree) to symamd, for it to allocate
+            memory for the temporary matrix M.
+
+        Returns:
+
+            TRUE (1) if successful, FALSE (0) otherwise.
+
+        Arguments:
+
+            int n ;             Input argument.
+
+                Number of rows and columns in the symmetrix matrix A.
+                Restriction:  n >= 0.
+                Symamd returns FALSE if n is negative.
+
+            int A [nnz] ;       Input argument.
+
+                A is an integer array of size nnz, where nnz = p [n].
+
+                The row indices of the entries in column c of the matrix are
+                held in A [(p [c]) ... (p [c+1]-1)].  The row indices in a
+                given column c need not be in ascending order, and duplicate
+                row indices may be present.  However, symamd will run faster
+                if the columns are in sorted order with no duplicate entries.
+
+                The matrix is 0-based.  That is, rows are in the range 0 to
+                n-1, and columns are in the range 0 to n-1.  Symamd
+                returns FALSE if any row index is out of range.
+
+                The contents of A are not modified.
+
+            int p [n+1] ;       Input argument.
+
+                p is an integer array of size n+1.  On input, it holds the
+                "pointers" for the column form of the matrix A.  Column c of
+                the matrix A is held in A [(p [c]) ... (p [c+1]-1)].  The first
+                entry, p [0], must be zero, and p [c] <= p [c+1] must hold
+                for all c in the range 0 to n-1.  The value p [n] is
+                thus the total number of entries in the pattern of the matrix A.
+                Symamd returns FALSE if these conditions are not met.
+
+                The contents of p are not modified.
+
+            int perm [n+1] ;    Output argument.
+
+                On output, if symamd returns TRUE, the array perm holds the
+                permutation P, where perm [0] is the first index in the new
+                ordering, and perm [n-1] is the last.  That is, perm [k] = j
+                means that row and column j of A is the kth column in PAP',
+                where k is in the range 0 to n-1 (perm [0] = j means
+                that row and column j of A are the first row and column in
+                PAP').  The array is used as a workspace during the ordering,
+                which is why it must be of length n+1, not just n.

+                                "empty" if it contains only "dense" and/or

+   Our "scaffolding code" philosophy:  In our opinion, well-written library
+   code should keep its "debugging" code, and just normally have it turned off
+   by the compiler so as not to interfere with performance.  This serves
+   several purposes:
+
+   (1) assertions act as comments to the reader, telling you what the code
+        expects at that point.  All assertions will always be true (unless
+        there really is a bug, of course).
+
+   (2) leaving in the scaffolding code assists anyone who would like to modify
+        the code, or understand the algorithm (by reading the debugging output,
+        one can get a glimpse into what the code is doing).
+
+   (3) (gasp!) for actually finding bugs.  This code has been heavily tested
+        and "should" be fully functional and bug-free ... but you never know...
+
+    The code will become outrageously slow when debugging is
+    enabled.  To control the level of debugging output, set an environment
+    variable D to 0 (little), 1 (some), 2, 3, or 4 (lots).  When debugging,
+    you should see the following message on the standard output:
+
+        colamd: debug version, D = 1 (THIS WILL BE SLOW!)
+
+    or a similar message for symamd.  If you don't, then debugging has not
+    been enabled.

+*  NAME
+*
+*  glp_simplex - solve LP problem with the simplex method
+*
+*  SYNOPSIS
+*
+*  int glp_simplex(glp_prob *P, const glp_smcp *parm);
+*
+*  DESCRIPTION
+*
+*  The routine glp_simplex is a driver to the LP solver based on the
+*  simplex method. This routine retrieves problem data from the
+*  specified problem object, calls the solver to solve the problem
+*  instance, and stores results of computations back into the problem
+*  object.
+*
+*  The simplex solver has a set of control parameters. Values of the
+*  control parameters can be passed in a structure glp_smcp, which the
+*  parameter parm points to.
+*
+*  The parameter parm can be specified as NULL, in which case the LP
+*  solver uses default settings.
+*
+*  RETURNS
+*
+*  0  The LP problem instance has been successfully solved. This code
+*     does not necessarily mean that the solver has found optimal
+*     solution. It only means that the solution process was successful.
+*
+*  GLP_EBADB
+*     Unable to start the search, because the initial basis specified
+*     in the problem object is invalid--the number of basic (auxiliary
+*     and structural) variables is not the same as the number of rows in
+*     the problem object.
+*
+*  GLP_ESING
+*     Unable to start the search, because the basis matrix correspodning
+*     to the initial basis is singular within the working precision.
+*
+*  GLP_ECOND
+*     Unable to start the search, because the basis matrix correspodning
+*     to the initial basis is ill-conditioned, i.e. its condition number
+*     is too large.
+*
+*  GLP_EBOUND
+*     Unable to start the search, because some double-bounded variables
+*     have incorrect bounds.
+*
+*  GLP_EFAIL
+*     The search was prematurely terminated due to the solver failure.
+*
+*  GLP_EOBJLL
+*     The search was prematurely terminated, because the objective
+*     function being maximized has reached its lower limit and continues
+*     decreasing (dual simplex only).
+*
+*  GLP_EOBJUL
+*     The search was prematurely terminated, because the objective
+*     function being minimized has reached its upper limit and continues
+*     increasing (dual simplex only).
+*
+*  GLP_EITLIM
+*     The search was prematurely terminated, because the simplex
+*     iteration limit has been exceeded.
+*
+*  GLP_ETMLIM
+*     The search was prematurely terminated, because the time limit has
+*     been exceeded.
+*
+*  GLP_ENOPFS
+*     The LP problem instance has no primal feasible solution (only if
+*     the LP presolver is used).
+*
+*  GLP_ENODFS
+*     The LP problem instance has no dual feasible solution (only if the
+*     LP presolver is used). */

+*  NAME
+*
+*  glp_exact - solve LP problem in exact arithmetic
+*
+*  SYNOPSIS
+*
+*  int glp_exact(glp_prob *lp, const glp_smcp *parm);
+*
+*  DESCRIPTION
+*
+*  The routine glp_exact is a tentative implementation of the primal
+*  two-phase simplex method based on exact (rational) arithmetic. It is
+*  similar to the routine glp_simplex, however, for all internal
+*  computations it uses arithmetic of rational numbers, which is exact
+*  in mathematical sense, i.e. free of round-off errors unlike floating
+*  point arithmetic.
+*
+*  Note that the routine glp_exact uses inly two control parameters
+*  passed in the structure glp_smcp, namely, it_lim and tm_lim.
+*
+*  RETURNS
+*
+*  0  The LP problem instance has been successfully solved. This code
+*     does not necessarily mean that the solver has found optimal
+*     solution. It only means that the solution process was successful.
+*
+*  GLP_EBADB
+*     Unable to start the search, because the initial basis specified
+*     in the problem object is invalid--the number of basic (auxiliary
+*     and structural) variables is not the same as the number of rows in
+*     the problem object.
+*
+*  GLP_ESING
+*     Unable to start the search, because the basis matrix correspodning
+*     to the initial basis is exactly singular.
+*
+*  GLP_EBOUND
+*     Unable to start the search, because some double-bounded variables
+*     have incorrect bounds.
+*
+*  GLP_EFAIL
+*     The problem has no rows/columns.
+*
+*  GLP_EITLIM
+*     The search was prematurely terminated, because the simplex
+*     iteration limit has been exceeded.
+*
+*  GLP_ETMLIM
+*     The search was prematurely terminated, because the time limit has
+*     been exceeded. */

+*  glp_interior - solve LP problem with the interior-point method
+*
+*  SYNOPSIS
+*
+*  int glp_interior(glp_prob *P, const glp_iptcp *parm);
+*
+*  The routine glp_interior is a driver to the LP solver based on the
+*  interior-point method.
+*
+*  The interior-point solver has a set of control parameters. Values of
+*  the control parameters can be passed in a structure glp_iptcp, which
+*  the parameter parm points to.
+*
+*  Currently this routine implements an easy variant of the primal-dual
+*  interior-point method based on Mehrotra's technique.
+*
+*  This routine transforms the original LP problem to an equivalent LP
+*  problem in the standard formulation (all constraints are equalities,
+*  all variables are non-negative), calls the routine ipm_main to solve
+*  the transformed problem, and then transforms an obtained solution to
+*  the solution of the original problem.
+*
+*  RETURNS
+*
+*  0  The LP problem instance has been successfully solved. This code
+*     does not necessarily mean that the solver has found optimal
+*     solution. It only means that the solution process was successful.
+*
+*  GLP_EFAIL
+*     The problem has no rows/columns.
+*
+*  GLP_ENOCVG
+*     Very slow convergence or divergence.
+*
+*  GLP_EITLIM
+*     Iteration limit exceeded.
+*
+*  GLP_EINSTAB
+*     Numerical instability on solving Newtonian system. */

+*
+*  SYNOPSIS
+*
+*  int glp_intopt(glp_prob *P, const glp_iocp *parm);
+*
+*  DESCRIPTION
+*
+*  The routine glp_intopt is a driver to the MIP solver based on the
+*  branch-and-bound method.
+*
+*  On entry the problem object should contain optimal solution to LP
+*  relaxation (which can be obtained with the routine glp_simplex).
+*
+*  The MIP solver has a set of control parameters. Values of the control
+*  parameters can be passed in a structure glp_iocp, which the parameter
+*  parm points to.
+*
+*  The parameter parm can be specified as NULL, in which case the MIP
+*  solver uses default settings.
+*
+*  RETURNS
+*
+*  0  The MIP problem instance has been successfully solved. This code
+*     does not necessarily mean that the solver has found optimal
+*     solution. It only means that the solution process was successful.
+*
+*  GLP_EBOUND
+*     Unable to start the search, because some double-bounded variables
+*     have incorrect bounds or some integer variables have non-integer
+*     (fractional) bounds.
+*
+*  GLP_EROOT
+*     Unable to start the search, because optimal basis for initial LP
+*     relaxation is not provided.
+*
+*  GLP_EFAIL
+*     The search was prematurely terminated due to the solver failure.
+*
+*  GLP_EMIPGAP
+*     The search was prematurely terminated, because the relative mip
+*     gap tolerance has been reached.
+*
+*  GLP_ETMLIM
+*     The search was prematurely terminated, because the time limit has
+*     been exceeded.
+*
+*  GLP_ENOPFS
+*     The MIP problem instance has no primal feasible solution (only if
+*     the MIP presolver is used).
+*
+*  GLP_ENODFS
+*     LP relaxation of the MIP problem instance has no dual feasible
+*     solution (only if the MIP presolver is used).
+*
+*  GLP_ESTOP
+*     The search was prematurely terminated by application. */

+*
+*  SYNOPSIS
+*
+*  int glp_eval_tab_row(glp_prob *lp, int k, int ind[], double val[]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_eval_tab_row computes a row of the current simplex
+*  tableau for the basic variable, which is specified by the number k:
+*  if 1 <= k <= m, x[k] is k-th auxiliary variable; if m+1 <= k <= m+n,
+*  x[k] is (k-m)-th structural variable, where m is number of rows, and
+*  n is number of columns. The current basis must be available.
+*
+*  The routine stores column indices and numerical values of non-zero
+*  elements of the computed row using sparse format to the locations
+*  ind[1], ..., ind[len] and val[1], ..., val[len], respectively, where
+*  0 <= len <= n is number of non-zeros returned on exit.
+*
+*  Element indices stored in the array ind have the same sense as the
+*  index k, i.e. indices 1 to m denote auxiliary variables and indices
+*  m+1 to m+n denote structural ones (all these variables are obviously
+*  non-basic by definition).
+*
+*  The computed row shows how the specified basic variable x[k] = xB[i]
+*  depends on non-basic variables:
+*
+*     xB[i] = alfa[i,1]*xN[1] + alfa[i,2]*xN[2] + ... + alfa[i,n]*xN[n],
+*
+*  where alfa[i,j] are elements of the simplex table row, xN[j] are
+*  non-basic (auxiliary and structural) variables.
+*
+*  RETURNS
+*
+*  The routine returns number of non-zero elements in the simplex table
+*  row stored in the arrays ind and val.
+*
+*  BACKGROUND
+*
+*  The system of equality constraints of the LP problem is:

+*     xR = A * xS,                                                   (1)
+*
+*  where xR is the vector of auxliary variables, xS is the vector of
+*  structural variables, A is the matrix of constraint coefficients.
+*
+*  The system (1) can be written in homogenous form as follows:
+*
+*     A~ * x = 0,                                                    (2)
+*
+*  where A~ = (I | -A) is the augmented constraint matrix (has m rows
+*  and m+n columns), x = (xR | xS) is the vector of all (auxiliary and
+*  structural) variables.
+*
+*  By definition for the current basis we have:
+*
+*     A~ = (B | N),                                                  (3)
+*
+*  where B is the basis matrix. Thus, the system (2) can be written as:
+*
+*     B * xB + N * xN = 0.                                           (4)
+*
+*  From (4) it follows that:
+*
+*     xB = A^ * xN,                                                  (5)
+*
+*  where the matrix
+*
+*     A^ = - inv(B) * N                                              (6)
+*
+*  is called the simplex table.
+*
+*  It is understood that i-th row of the simplex table is:
+*
+*     e * A^ = - e * inv(B) * N,                                     (7)
+*
+*  where e is a unity vector with e[i] = 1.
+*
+*  To compute i-th row of the simplex table the routine first computes
+*  i-th row of the inverse:
+*
+*     rho = inv(B') * e,                                             (8)
+*
+*  where B' is a matrix transposed to B, and then computes elements of
+*  i-th row of the simplex table as scalar products:
+*
+*     alfa[i,j] = - rho * N[j]   for all j,                          (9)
+*
+*  where N[j] is a column of the augmented constraint matrix A~, which
+*  corresponds to some non-basic auxiliary or structural variable. */

+*  NAME
+*
+*  glp_eval_tab_col - compute column of the simplex tableau
+*
+*  SYNOPSIS
+*
+*  int glp_eval_tab_col(glp_prob *lp, int k, int ind[], double val[]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_eval_tab_col computes a column of the current simplex
+*  table for the non-basic variable, which is specified by the number k:
+*  if 1 <= k <= m, x[k] is k-th auxiliary variable; if m+1 <= k <= m+n,
+*  x[k] is (k-m)-th structural variable, where m is number of rows, and
+*  n is number of columns. The current basis must be available.
+*
+*  The routine stores row indices and numerical values of non-zero
+*  elements of the computed column using sparse format to the locations
+*  ind[1], ..., ind[len] and val[1], ..., val[len] respectively, where
+*  0 <= len <= m is number of non-zeros returned on exit.
+*
+*  Element indices stored in the array ind have the same sense as the
+*  index k, i.e. indices 1 to m denote auxiliary variables and indices
+*  m+1 to m+n denote structural ones (all these variables are obviously
+*  basic by the definition).
+*
+*  The computed column shows how basic variables depend on the specified
+*  non-basic variable x[k] = xN[j]:
+*
+*     xB[1] = ... + alfa[1,j]*xN[j] + ...
+*     xB[2] = ... + alfa[2,j]*xN[j] + ...
+*              . . . . . .
+*     xB[m] = ... + alfa[m,j]*xN[j] + ...
+*
+*  where alfa[i,j] are elements of the simplex table column, xB[i] are
+*  basic (auxiliary and structural) variables.
+*
+*  RETURNS
+*
+*  The routine returns number of non-zero elements in the simplex table
+*  column stored in the arrays ind and val.
+*
+*  BACKGROUND
+*
+*  As it was explained in comments to the routine glp_eval_tab_row (see
+*  above) the simplex table is the following matrix:
+*
+*     A^ = - inv(B) * N.                                             (1)
+*
+*  Therefore j-th column of the simplex table is:
+*
+*     A^ * e = - inv(B) * N * e = - inv(B) * N[j],                   (2)
+*
+*  where e is a unity vector with e[j] = 1, B is the basis matrix, N[j]
+*  is a column of the augmented constraint matrix A~, which corresponds
+*  to the given non-basic auxiliary or structural variable. */

+*  glp_transform_row - transform explicitly specified row
+*
+*  SYNOPSIS
+*
+*  int glp_transform_row(glp_prob *P, int len, int ind[], double val[]);
+*
+*  DESCRIPTION
+*
+*  The routine glp_transform_row performs the same operation as the
+*  routine glp_eval_tab_row with exception that the row to be
+*  transformed is specified explicitly as a sparse vector.
+*
+*  The explicitly specified row may be thought as a linear form:
+*
+*     x = a[1]*x[m+1] + a[2]*x[m+2] + ... + a[n]*x[m+n],             (1)
+*
+*  where x is an auxiliary variable for this row, a[j] are coefficients
+*  of the linear form, x[m+j] are structural variables.
+*
+*  On entry column indices and numerical values of non-zero elements of
+*  the row should be stored in locations ind[1], ..., ind[len] and
+*  val[1], ..., val[len], where len is the number of non-zero elements.
+*
+*  This routine uses the system of equality constraints and the current
+*  basis in order to express the auxiliary variable x in (1) through the
+*  current non-basic variables (as if the transformed row were added to
+*  the problem object and its auxiliary variable were basic), i.e. the
+*  resultant row has the form:
+*
+*     x = alfa[1]*xN[1] + alfa[2]*xN[2] + ... + alfa[n]*xN[n],       (2)
+*
+*  where xN[j] are non-basic (auxiliary or structural) variables, n is
+*  the number of columns in the LP problem object.
+*
+*  On exit the routine stores indices and numerical values of non-zero
+*  elements of the resultant row (2) in locations ind[1], ..., ind[len']
+*  and val[1], ..., val[len'], where 0 <= len' <= n is the number of
+*  non-zero elements in the resultant row returned by the routine. Note
+*  that indices (numbers) of non-basic variables stored in the array ind
+*  correspond to original ordinal numbers of variables: indices 1 to m
+*  mean auxiliary variables and indices m+1 to m+n mean structural ones.
+*
+*  RETURNS
+*
+*  The routine returns len', which is the number of non-zero elements in
+*  the resultant row stored in the arrays ind and val.
+*
+*  BACKGROUND
+*
+*  The explicitly specified row (1) is transformed in the same way as it
+*  were the objective function row.
+*
+*  From (1) it follows that:
+*
+*     x = aB * xB + aN * xN,                                         (3)
+*
+*  where xB is the vector of basic variables, xN is the vector of
+*  non-basic variables.
+*
+*  The simplex table, which corresponds to the current basis, is:
+*
+*     xB = [-inv(B) * N] * xN.                                       (4)
+*
+*  Therefore substituting xB from (4) to (3) we have:
+*
+*     x = aB * [-inv(B) * N] * xN + aN * xN =
+*                                                                    (5)
+*       = rho * (-N) * xN + aN * xN = alfa * xN,

+*
+*  and
+*

+*  glp_prim_rtest - perform primal ratio test
+*
+*  SYNOPSIS
+*
+*  int glp_prim_rtest(glp_prob *P, int len, const int ind[],
+*     const double val[], int dir, double eps);
+*
+*  DESCRIPTION
+*
+*  The routine glp_prim_rtest performs the primal ratio test using an
+*  explicitly specified column of the simplex table.
+*
+*  The current basic solution associated with the LP problem object
+*  must be primal feasible.
+*
+*  The explicitly specified column of the simplex table shows how the
+*  basic variables xB depend on some non-basic variable x (which is not
+*  necessarily presented in the problem object):
+*
+*     xB[1] = ... + alfa[1] * x + ...
+*     xB[2] = ... + alfa[2] * x + ...                                (*)
+*         .  .  .  .  .  .  .  .
+*     xB[m] = ... + alfa[m] * x + ...
+*
+*  The column (*) is specifed on entry to the routine using the sparse
+*  format. Ordinal numbers of basic variables xB[i] should be placed in
+*  locations ind[1], ..., ind[len], where ordinal number 1 to m denote
+*  auxiliary variables, and ordinal numbers m+1 to m+n denote structural
+*  variables. The corresponding non-zero coefficients alfa[i] should be
+*  placed in locations val[1], ..., val[len]. The arrays ind and val are
+*  not changed on exit.
+*
+*  The parameter dir specifies direction in which the variable x changes
+*  on entering the basis: +1 means increasing, -1 means decreasing.
+*
+*  The parameter eps is an absolute tolerance (small positive number)
+*  used by the routine to skip small alfa[j] of the row (*).
+*
+*  The routine determines which basic variable (among specified in
+*  ind[1], ..., ind[len]) should leave the basis in order to keep primal
+*  feasibility.
+*
+*  RETURNS
+*
+*  The routine glp_prim_rtest returns the index piv in the arrays ind
+*  and val corresponding to the pivot element chosen, 1 <= piv <= len.
+*  If the adjacent basic solution is primal unbounded and therefore the
+*  choice cannot be made, the routine returns zero.
+*
+*  COMMENTS
+*
+*  If the non-basic variable x is presented in the LP problem object,
+*  the column (*) can be computed with the routine glp_eval_tab_col;
+*  otherwise it can be computed with the routine glp_transform_col. */

+*  NAME
+*
+*  glp_analyze_row - simulate one iteration of dual simplex method
+*
+*  SYNOPSIS
+*
+*  int glp_analyze_row(glp_prob *P, int len, const int ind[],
+*     const double val[], int type, double rhs, double eps, int *piv,
+*     double *x, double *dx, double *y, double *dy, double *dz);
+*
+*  DESCRIPTION
+*
+*  Let the current basis be optimal or dual feasible, and there be
+*  specified a row (constraint), which is violated by the current basic
+*  solution. The routine glp_analyze_row simulates one iteration of the
+*  dual simplex method to determine some information on the adjacent
+*  basis (see below), where the specified row becomes active constraint
+*  (i.e. its auxiliary variable becomes non-basic).
+*
+*  The current basic solution associated with the problem object passed
+*  to the routine must be dual feasible, and its primal components must
+*  be defined.
+*
+*  The row to be analyzed must be previously transformed either with
+*  the routine glp_eval_tab_row (if the row is in the problem object)
+*  or with the routine glp_transform_row (if the row is external, i.e.
+*  not in the problem object). This is needed to express the row only
+*  through (auxiliary and structural) variables, which are non-basic in
+*  the current basis:
+*
+*     y = alfa[1] * xN[1] + alfa[2] * xN[2] + ... + alfa[n] * xN[n],
+*
+*  where y is an auxiliary variable of the row, alfa[j] is an influence
+*  coefficient, xN[j] is a non-basic variable.
+*
+*  The row is passed to the routine in sparse format. Ordinal numbers
+*  of non-basic variables are stored in locations ind[1], ..., ind[len],
+*  where numbers 1 to m denote auxiliary variables while numbers m+1 to
+*  m+n denote structural variables. Corresponding non-zero coefficients
+*  alfa[j] are stored in locations val[1], ..., val[len]. The arrays
+*  ind and val are ot changed on exit.
+*
+*  The parameters type and rhs specify the row type and its right-hand
+*  side as follows:
+*
+*     type = GLP_LO: y = sum alfa[j] * xN[j] >= rhs
+*
+*     type = GLP_UP: y = sum alfa[j] * xN[j] <= rhs
+*
+*  The parameter eps is an absolute tolerance (small positive number)
+*  used by the routine to skip small coefficients alfa[j] on performing
+*  the dual ratio test.
+*
+*  If the operation was successful, the routine stores the following
+*  information to corresponding location (if some parameter is NULL,
+*  its value is not stored):
+*
+*  piv   index in the array ind and val, 1 <= piv <= len, determining
+*        the non-basic variable, which would enter the adjacent basis;
+*
+*  x     value of the non-basic variable in the current basis;
+*
+*  dx    difference between values of the non-basic variable in the
+*        adjacent and current bases, dx = x.new - x.old;
+*
+*  y     value of the row (i.e. of its auxiliary variable) in the
+*        current basis;
+*
+*  dy    difference between values of the row in the adjacent and
+*        current bases, dy = y.new - y.old;
+*
+*  dz    difference between values of the objective function in the
+*        adjacent and current bases, dz = z.new - z.old. Note that in
+*        case of minimization dz >= 0, and in case of maximization
+*        dz <= 0, i.e. in the adjacent basis the objective function
+*        always gets worse (degrades). */

+*
+*  var1 is the ordinal number of an auxiliary (1 to m) or structural

+*     double *value1, double *coef2, int *var2, double *value2);
+*
+*  DESCRIPTION
+*
+*  The routine glp_analyze_coef analyzes the effect of varying the
+*  objective coefficient at specified basic variable.
+*
+*  The basic variable is specified by the parameter k, where
+*  1 <= k <= m means auxiliary variable of corresponding row while
+*  m+1 <= k <= m+n means structural variable (column).
+*
+*  Note that the current basic solution must be optimal, and the basis
+*  factorization must exist.
+*
+*  Results of the analysis have the following meaning.
+*
+*  coef1 is the minimal value of the objective coefficient, at which
+*  the basis still remains dual feasible and thus optimal. -DBL_MAX
+*  means that the objective coefficient has no lower limit.
+*
+*  var1 is the ordinal number of an auxiliary (1 to m) or structural
+*  (m+1 to n) non-basic variable, whose reduced cost reaches its zero
+*  bound first and thereby limits further decreasing the objective
+*  coefficient being analyzed. If coef1 = -DBL_MAX, var1 is set to 0.
+*
+*  value1 is value of the basic variable being analyzed in an adjacent
+*  basis, which is defined as follows. Let the objective coefficient
+*  reaches its minimal value (coef1) and continues decreasing. Then the
+*  reduced cost of the limiting non-basic variable (var1) becomes dual
+*  infeasible and the current basis becomes non-optimal that forces the
+*  limiting non-basic variable to enter the basis replacing there some
+*  basic variable that leaves the basis to keep primal feasibility.
+*  Should note that on determining the adjacent basis current bounds
+*  of the basic variable being analyzed are ignored as if it were free
+*  (unbounded) variable, so it cannot leave the basis. It may happen
+*  that no dual feasible adjacent basis exists, in which case value1 is
+*  set to -DBL_MAX or +DBL_MAX.
+*
+*  coef2 is the maximal value of the objective coefficient, at which
+*  the basis still remains dual feasible and thus optimal. +DBL_MAX
+*  means that the objective coefficient has no upper limit.
+*
+*  var2 is the ordinal number of an auxiliary (1 to m) or structural
+*  (m+1 to n) non-basic variable, whose reduced cost reaches its zero
+*  bound first and thereby limits further increasing the objective
+*  coefficient being analyzed. If coef2 = +DBL_MAX, var2 is set to 0.
+*
+*  value2 is value of the basic variable being analyzed in an adjacent
+*  basis, which is defined exactly in the same way as value1 above with
+*  exception that now the objective coefficient is increasing. */

+*  SYNOPSIS

+*  #include "glpios.h"
+*  double ios_round_bound(glp_tree *tree, double bound);
+*
+*  RETURNS
+*
+*  For the given local bound for any integer feasible solution to the
+*  current subproblem the routine ios_round_bound returns an improved
+*  local bound for the same integer feasible solution.
+*
+*  BACKGROUND
+*
+*  Let the current subproblem has the following objective function:
+*
+*     z =   sum  c[j] * x[j] + s >= b,                               (1)
+*         j in J
+*
+*  where J = {j: c[j] is non-zero and integer, x[j] is integer}, s is
+*  the sum of terms corresponding to fixed variables, b is an initial
+*  local bound (minimization).
+*
+*  From (1) it follows that:
+*
+*     d *  sum  (c[j] / d) * x[j] + s >= b,                          (2)
+*        j in J
+*
+*  or, equivalently,
+*
+*     sum  (c[j] / d) * x[j] >= (b - s) / d = h,                     (3)
+*   j in J
+*
+*  where d = gcd(c[j]). Since the left-hand side of (3) is integer,
+*  h = (b - s) / d can be rounded up to the nearest integer:
+*
+*     h' = ceil(h) = (b' - s) / d,                                   (4)
+*
+*  that gives an rounded, improved local bound:
+*
+*     b' = d * h' + s.                                               (5)
+*
+*  In case of maximization '>=' in (1) should be replaced by '<=' that
+*  leads to the following formula:
+*
+*     h' = floor(h) = (b' - s) / d,                                  (6)
+*
+*  which should used in the same way as (4).

+*

+*     and u[k] = +inf, then
+*
+*     f_min :=   sum   a[j] * l[j] +   sum   a[j] * u[j]
+*              j in J+               j in J-
+*                                                                    (3)
+*     j_min := 0
+*
+*  2) if there is exactly one x[k] such that k in J+ and l[k] = -inf
+*     or k in J- and u[k] = +inf, then
+*
+*     f_min :=   sum       a[j] * l[j] +   sum       a[j] * u[j]
+*              j in J+\{k}               j in J-\{k}

+*     j_min := k
+*
+*  3) if there are two or more x[k] such that k in J+ and l[k] = -inf
+*     or k in J- and u[k] = +inf, then
+*
+*     f_min := -inf
+*                                                                    (5)
+*     j_min := 0
+*
+*  Parameters f_max and j_max are computed in a similar way as follows:
+*
+*  1) if there is no x[k] such that k in J+ and u[k] = +inf or k in J-
+*     and l[k] = -inf, then
+*
+*     f_max :=   sum   a[j] * u[j] +   sum   a[j] * l[j]
+*              j in J+               j in J-
+*                                                                    (6)
+*     j_max := 0
+*
+*  2) if there is exactly one x[k] such that k in J+ and u[k] = +inf

+*  This routine checks if the basic solution of LP relaxation of the
+*  current subproblem satisfies to integrality conditions, i.e. that all
+*  variables of integer kind have integral primal values. (The solution
+*  is assumed to be optimal.)
+*
+*  For each variable of integer kind the routine computes the following
+*  quantity:
+*
+*     ii(x[j]) = min(x[j] - floor(x[j]), ceil(x[j]) - x[j]),         (1)
+*
+*  which is a measure of the integer infeasibility (non-integrality) of
+*  x[j] (for example, ii(2.1) = 0.1, ii(3.7) = 0.3, ii(5.0) = 0). It is
+*  understood that 0 <= ii(x[j]) <= 0.5, and variable x[j] is integer
+*  feasible if ii(x[j]) = 0. However, due to floating-point arithmetic
+*  the routine checks less restrictive condition:
+*
+*     ii(x[j]) <= tol_int,                                           (2)
+*
+*  where tol_int is a given tolerance (small positive number) and marks
+*  each variable which does not satisfy to (2) as integer infeasible by
+*  setting its fractionality flag.
+*
+*  In order to characterize integer infeasibility of the basic solution
+*  in the whole the routine computes two parameters: ii_cnt, which is
+*  the number of variables with the fractionality flag set, and ii_sum,
+*  which is the sum of integer infeasibilities (1). */

+-- COVER INEQUALITIES
+--
+-- Consider the set of feasible solutions to 0-1 knapsack problem:
+--
+--    sum a[j]*x[j] <= b,                                            (1)
+--  j in J
+--
+--    x[j] is binary,                                                (2)
+--
+-- where, wlog, we assume that a[j] > 0 (since 0-1 variables can be
+-- complemented) and a[j] <= b (since a[j] > b implies x[j] = 0).
+--
+-- A set C within J is called a cover if
+--
+--    sum a[j] > b.                                                  (3)
+--  j in C
+--
+-- For any cover C the inequality
+--
+--    sum x[j] <= |C| - 1                                            (4)
+--  j in C
+--
+-- is called a cover inequality and is valid for (1)-(2).
+--
+-- MIXED COVER INEQUALITIES
+--
+-- Consider the set of feasible solutions to mixed knapsack problem:
+--
+--    sum a[j]*x[j] + y <= b,                                        (5)
+--  j in J
+--
+--    x[j] is binary,                                                (6)
+--
+--    0 <= y <= u is continuous,                                     (7)
+--
+-- where again we assume that a[j] > 0.
+--
+-- Let C within J be some set. From (1)-(4) it follows that
+--
+--    sum a[j] > b - y                                               (8)
+--  j in C
+--
+-- implies
+--
+--    sum x[j] <= |C| - 1.                                           (9)
+--  j in C
+--
+-- Thus, we need to modify the inequality (9) in such a way that it be
+-- a constraint only if the condition (8) is satisfied.
+--
+-- Consider the following inequality:
+--
+--    sum x[j] <= |C| - t.                                          (10)
+--  j in C
+--
+-- If 0 < t <= 1, then (10) is equivalent to (9), because all x[j] are
+-- binary variables. On the other hand, if t <= 0, (10) being satisfied
+-- for any values of x[j] is not a constraint.
+--
+-- Let
+--
+--    t' = sum a[j] + y - b.                                        (11)
+--       j in C
+--
+-- It is understood that the condition t' > 0 is equivalent to (8).
+-- Besides, from (6)-(7) it follows that t' has an implied upper bound:
+--
+--    t'max = sum a[j] + u - b.                                     (12)
+--          j in C
+--
+-- This allows to express the parameter t having desired properties:
+--
+--    t = t' / t'max.                                               (13)
+--
+-- In fact, t <= 1 by definition, and t > 0 being equivalent to t' > 0
+-- is equivalent to (8).
+--
+-- Thus, the inequality (10), where t is given by formula (13) is valid
+-- for (5)-(7).
+--
+-- Note that if u = 0, then y = 0, so t = 1, and the conditions (8) and
+-- (10) is transformed to the conditions (3) and (4).
+--
+-- GENERATING MIXED COVER CUTS
+--
+-- To generate a mixed cover cut in the form (10) we need to find such
+-- set C which satisfies to the inequality (8) and for which, in turn,
+-- the inequality (10) is violated in the current point.
+--
+-- Substituting t from (13) to (10) gives:
+--
+--                        1
+--    sum x[j] <= |C| - -----  (sum a[j] + y - b),                  (14)
+--  j in C              t'max j in C
+--
+-- and finally we have the cut inequality in the standard form:
+--
+--    sum x[j] + alfa * y <= beta,                                  (15)
+--  j in C
+--
+-- where:
+--
+--    alfa = 1 / t'max,                                             (16)
+--
+--    beta = |C| - alfa *  (sum a[j] - b).                          (17)
+--                        j in C                                      */

+--
+-- SYNOPSIS
+--
+-- int lpx_cover_cut(LPX *lp, int len, int ind[], double val[],
+--    double work[]);
+--
+-- DESCRIPTION
+--
+-- The routine lpx_cover_cut generates a mixed cover cut for a given
+-- row of the MIP problem.
+--
+-- The given row of the MIP problem should be explicitly specified in
+-- the form:
+--
+--    sum{j in J} a[j]*x[j] <= b.                                    (1)
+--
+-- On entry indices (ordinal numbers) of structural variables, which
+-- have non-zero constraint coefficients, should be placed in locations
+-- ind[1], ..., ind[len], and corresponding constraint coefficients
+-- should be placed in locations val[1], ..., val[len]. The right-hand
+-- side b should be stored in location val[0].
+--
+-- The working array work should have at least nb locations, where nb
+-- is the number of binary variables in (1).
+--
+-- The routine generates a mixed cover cut in the same form as (1) and
+-- stores the cut coefficients and right-hand side in the same way as
+-- just described above.
+--
+-- RETURNS
+--
+-- If the cutting plane has been successfully generated, the routine
+-- returns 1 <= len' <= n, which is the number of non-zero coefficients
+-- in the inequality constraint. Otherwise, the routine returns zero. */

+--
+-- On entry column indices and numerical values of non-zero elements of
+-- the row should be stored in locations ind[1], ..., ind[len] and

+*  ios_process_cuts - process cuts stored in the local cut pool
+*
+*  SYNOPSIS
+*
+*  #include "glpios.h"
+*  void ios_process_cuts(glp_tree *T);
+*
+*  DESCRIPTION
+*
+*  The routine ios_process_cuts analyzes each cut currently stored in
+*  the local cut pool, which must be non-empty, and either adds the cut
+*  to the current subproblem or just discards it. All cuts are assumed
+*  to be locally valid. On exit the local cut pool remains unchanged.

+*
+*  S. Mehrotra. On the implementation of a primal-dual interior point
+*  method. SIAM J. on Optim., 2(4), pp. 575-601, 1992.
+*
+*  At first, the routine computes so called affine scaling (predictor)
+*  direction (dx_aff,dy_aff,dz_aff) which is a solution of the system:
+*
+*     A*dx_aff                       = b - A*x
+*
+*               A'*dy_aff +   dz_aff = c - A'*y - z
+*
+*     Z*dx_aff            + X*dz_aff = - X*Z*e
+*
+*  where (x,y,z) is the current point, X = diag(x[j]), Z = diag(z[j]),
+*  e = (1,...,1)'.
+*
+*  Then, the routine computes the centering parameter sigma, using the
+*  following Mehrotra's heuristic:
+*
+*     alfa_aff_p = inf{0 <= alfa <= 1 | x+alfa*dx_aff >= 0}
+*
+*     alfa_aff_d = inf{0 <= alfa <= 1 | z+alfa*dz_aff >= 0}
+*
+*     mu_aff = (x+alfa_aff_p*dx_aff)'*(z+alfa_aff_d*dz_aff)/n
+*
+*     sigma = (mu_aff/mu)^3
+*
+*  where alfa_aff_p is the maximal stepsize along the affine scaling
+*  direction in the primal space, alfa_aff_d is the maximal stepsize
+*  along the same direction in the dual space.
+*
+*  After determining sigma the routine computes so called centering
+*  (corrector) direction (dx_cc,dy_cc,dz_cc) which is the solution of
+*  the system:
+*
+*     A*dx_cc                     = 0
+*
+*              A'*dy_cc +   dz_cc = 0
+*
+*     Z*dx_cc           + X*dz_cc = sigma*mu*e - X*Z*e
+*
+*  Finally, the routine computes the combined direction
+*
+*     (dx,dy,dz) = (dx_aff,dy_aff,dz_aff) + (dx_cc,dy_cc,dz_cc)
+*
+*  and determines maximal primal and dual stepsizes along the combined
+*  direction:
+*

+*  ipm_solve - core LP solver based on the interior-point method
+*
+*  SYNOPSIS
+*
+*  #include "glpipm.h"
+*  int ipm_solve(glp_prob *P, const glp_iptcp *parm);
+*
+*  DESCRIPTION
+*
+*  The routine ipm_solve is a core LP solver based on the primal-dual
+*  interior-point method.
+*
+*  The routine assumes the following standard formulation of LP problem
+*  to be solved:
+*
+*     minimize
+*
+*        F = c[0] + c[1]*x[1] + c[2]*x[2] + ... + c[n]*x[n]
+*
+*     subject to linear constraints
+*
+*        a[1,1]*x[1] + a[1,2]*x[2] + ... + a[1,n]*x[n] = b[1]
+*
+*        a[2,1]*x[1] + a[2,2]*x[2] + ... + a[2,n]*x[n] = b[2]
+*
+*              . . . . . .
+*
+*        a[m,1]*x[1] + a[m,2]*x[2] + ... + a[m,n]*x[n] = b[m]
+*
+*     and non-negative variables
+*
+*        x[1] >= 0, x[2] >= 0, ..., x[n] >= 0
+*
+*  where:
+*  F                    is the objective function;
+*  x[1], ..., x[n]      are (structural) variables;
+*  c[0]                 is a constant term of the objective function;
+*  c[1], ..., c[n]      are objective coefficients;
+*  a[1,1], ..., a[m,n]  are constraint coefficients;
+*  b[1], ..., b[n]      are right-hand sides.
+*
+*  The solution is three vectors x, y, and z, which are stored by the
+*  routine in the arrays x, y, and z, respectively. These vectors
+*  correspond to the best primal-dual point found during optimization.
+*  They are approximate solution of the following system (which is the
+*  Karush-Kuhn-Tucker optimality conditions):
+*
+*     A*x      = b      (primal feasibility condition)
+*
+*     A'*y + z = c      (dual feasibility condition)
+*
+*     x'*z     = 0      (primal-dual complementarity condition)
+*
+*     x >= 0, z >= 0    (non-negativity condition)
+*
+*  where:
+*  x[1], ..., x[n]      are primal (structural) variables;
+*  y[1], ..., y[m]      are dual variables (Lagrange multipliers) for
+*                       equality constraints;
+*  z[1], ..., z[n]      are dual variables (Lagrange multipliers) for
+*                       non-negativity constraints.
+*
+*  RETURNS
+*
+*  0  LP has been successfully solved.
+*

+*
+*  GLP_EITLIM
+*     Iteration limit exceeded.

+*  GLP_EINSTAB
+*     Numeric instability on solving Newtonian system.
+*
+*  In case of non-zero return code the routine returns the best point,
+*  which has been reached during optimization. */

+-- *Synopsis*

+-- int *chol_symbolic(int n, int A_ptr[], int A_ind[], int U_ptr[]);
+--
+-- *Description*
+--
+-- The routine chol_symbolic implements the symbolic phase of Cholesky
+-- factorization A = U'*U, where A is a given sparse symmetric positive
+-- definite matrix, U is a resultant upper triangular factor, U' is a
+-- matrix transposed to U.
+--
+-- The parameter n is the order of matrices A and U.
+--
+-- The pattern of the given matrix A is specified on entry in the arrays
+-- A_ptr and A_ind in storage-by-rows format. Only the upper triangular
+-- part without diagonal elements (which all are assumed to be non-zero)
+-- should be specified as if A were upper triangular. The arrays A_ptr
+-- and A_ind are not changed on exit.
+--
+-- The pattern of the matrix U without diagonal elements (which all are
+-- assumed to be non-zero) is stored on exit from the routine in the
+-- arrays U_ptr and U_ind in storage-by-rows format. The array U_ptr
+-- should be allocated on entry, however, its content is ignored. The
+-- array U_ind is allocated by the routine which returns a pointer to it
+-- on exit.
+--
+-- *Returns*
+--
+-- The routine returns a pointer to the array U_ind.
+--
+-- *Method*
+--
+-- The routine chol_symbolic computes the pattern of the matrix U in a
+-- row-wise manner. No pivoting is used.
+--
+-- It is known that to compute the pattern of row k of the matrix U we
+-- need to merge the pattern of row k of the matrix A and the patterns
+-- of each row i of U, where u[i,k] is non-zero (these rows are already
+-- computed and placed above row k).
+--
+-- However, to reduce the number of rows to be merged the routine uses
+-- an advanced algorithm proposed in:
+--
+-- D.J.Rose, R.E.Tarjan, and G.S.Lueker. Algorithmic aspects of vertex
+-- elimination on graphs. SIAM J. Comput. 5, 1976, 266-83.
+--
+-- The authors of the cited paper show that we have the same result if
+-- we merge row k of the matrix A and such rows of the matrix U (among
+-- rows 1, ..., k-1) whose leftmost non-diagonal non-zero element is
+-- placed in k-th column. This feature signficantly reduces the number
+-- of rows to be merged, especially on the final steps, where rows of
+-- the matrix U become quite dense.
+--
+-- To determine rows, which should be merged on k-th step, for a fixed
+-- time the routine uses linked lists of row numbers of the matrix U.
+-- Location head[k] contains the number of a first row, whose leftmost
+-- non-diagonal non-zero element is placed in column k, and location
+-- next[i] contains the number of a next row with the same property as
+-- row i. */

+-- where A_diag[0] is not used, A_diag[i] = a[i,i] for i = 1, ..., n.
+-- The arrays A_ptr, A_ind, A_val, and A_diag are not changed on exit.
+--
+-- The pattern of the matrix U without diagonal elements (previously
+-- computed with the routine chol_symbolic) is specified in the arrays
+-- U_ptr and U_ind, which are not changed on exit. Numeric values of
+-- non-diagonal elements of U are stored in corresponding locations of
+-- the array U_val, and values of diagonal elements of U are stored in
+-- locations U_diag[1], ..., U_diag[n].
+--
+-- *Returns*
+--
+-- The routine returns the number of non-positive diagonal elements of
+-- the matrix U which have been replaced by a huge positive number (see
+-- the method description below). Zero return code means the matrix A
+-- has been successfully factorized.
+--
+-- *Method*
+--
+-- The routine chol_numeric computes the matrix U in a row-wise manner
+-- using standard gaussian elimination technique. No pivoting is used.
+--
+-- Initially the routine sets U = A, and before k-th elimination step
+-- the matrix U is the following:
+--
+--       1       k         n
+--    1  x x x x x x x x x x
+--       . x x x x x x x x x

+--       . . . x x x x x x x

+--       . . . . * * * * * *
+--       . . . . * * * * * *
+--       . . . . * * * * * *
+--    n  . . . . * * * * * *
+--
+-- where 'x' are elements of already computed rows, '*' are elements of
+-- the active submatrix. (Note that the lower triangular part of the
+-- active submatrix being symmetric is not stored and diagonal elements
+-- are stored separately in the array U_diag.)
+--
+-- The matrix A is assumed to be positive definite. However, if it is
+-- close to semi-definite, on some elimination step a pivot u[k,k] may
+-- happen to be non-positive due to round-off errors. In this case the
+-- routine uses a technique proposed in:
+--
+-- S.J.Wright. The Cholesky factorization in interior-point and barrier
+-- methods. Preprint MCS-P600-0596, Mathematics and Computer Science
+-- Division, Argonne National Laboratory, Argonne, Ill., May 1996.
+--
+-- The routine just replaces non-positive u[k,k] by a huge positive
+-- number. This involves non-diagonal elements in k-th row of U to be
+-- close to zero that, in turn, involves k-th component of a solution
+-- vector to be close to zero. Note, however, that this technique works
+-- only if the system A*x = b is consistent. */

+/***********************************************************************
+*  FULL-VECTOR STORAGE
+*
+*  For a sparse vector x having n elements, ne of which are non-zero,
+*  the full-vector storage format uses two arrays x_ind and x_vec, which
+*  are set up as follows:
+*
+*  x_ind is an integer array of length [1+ne]. Location x_ind[0] is
+*  not used, and locations x_ind[1], ..., x_ind[ne] contain indices of
+*  non-zero elements in vector x.
+*
+*  x_vec is a floating-point array of length [1+n]. Location x_vec[0]
+*  is not used, and locations x_vec[1], ..., x_vec[n] contain numeric
+*  values of ALL elements in vector x, including its zero elements.
+*
+*  Let, for example, the following sparse vector x be given:
+*
+*     (0, 1, 0, 0, 2, 3, 0, 4)
+*
+*  Then the arrays are:
+*
+*     x_ind = { X; 2, 5, 6, 8 }
+*
+*     x_vec = { X; 0, 1, 0, 0, 2, 3, 0, 4 }
+*
+*  COMPRESSED-VECTOR STORAGE
+*
+*  For a sparse vector x having n elements, ne of which are non-zero,
+*  the compressed-vector storage format uses two arrays x_ind and x_vec,
+*  which are set up as follows:
+*
+*  x_ind is an integer array of length [1+ne]. Location x_ind[0] is
+*  not used, and locations x_ind[1], ..., x_ind[ne] contain indices of
+*  non-zero elements in vector x.
+*
+*  x_vec is a floating-point array of length [1+ne]. Location x_vec[0]
+*  is not used, and locations x_vec[1], ..., x_vec[ne] contain numeric
+*  values of corresponding non-zero elements in vector x.
+*
+*  Let, for example, the following sparse vector x be given:
+*
+*     (0, 1, 0, 0, 2, 3, 0, 4)
+*
+*  Then the arrays are:
+*
+*     x_ind = { X; 2, 5, 6, 8 }
+*
+*     x_vec = { X; 1, 2, 3, 4 }
+*
+*  STORAGE-BY-ROWS
+*
+*  For a sparse matrix A, which has m rows, n columns, and ne non-zero
+*  elements the storage-by-rows format uses three arrays A_ptr, A_ind,
+*  and A_val, which are set up as follows:
+*
+*  A_ptr is an integer array of length [1+m+1] also called "row pointer
+*  array". It contains the relative starting positions of each row of A
+*  in the arrays A_ind and A_val, i.e. element A_ptr[i], 1 <= i <= m,
+*  indicates where row i begins in the arrays A_ind and A_val. If all
+*  elements in row i are zero, then A_ptr[i] = A_ptr[i+1]. Location
+*  A_ptr[0] is not used, location A_ptr[1] must contain 1, and location
+*  A_ptr[m+1] must contain ne+1 that indicates the position after the
+*  last element in the arrays A_ind and A_val.
+*
+*  A_ind is an integer array of length [1+ne]. Location A_ind[0] is not
+*  used, and locations A_ind[1], ..., A_ind[ne] contain column indices
+*  of (non-zero) elements in matrix A.
+*
+*  A_val is a floating-point array of length [1+ne]. Location A_val[0]
+*  is not used, and locations A_val[1], ..., A_val[ne] contain numeric
+*  values of non-zero elements in matrix A.
+*
+*  Non-zero elements of matrix A are stored contiguously, and the rows
+*  of matrix A are stored consecutively from 1 to m in the arrays A_ind
+*  and A_val. The elements in each row of A may be stored in any order
+*  in A_ind and A_val. Note that elements with duplicate column indices
+*  are not allowed.
+*
+*  Let, for example, the following sparse matrix A be given:
+*
+*     | 11  . 13  .  .  . |
+*     | 21 22  . 24  .  . |
+*     |  . 32 33  .  .  . |
+*     |  .  . 43 44  . 46 |
+*     |  .  .  .  .  .  . |
+*     | 61 62  .  .  . 66 |
+*
+*  Then the arrays are:
+*
+*     A_ptr = { X; 1, 3, 6, 8, 11, 11; 14 }
+*
+*     A_ind = { X;  1,  3;  4,  2,  1;  2,  3;  4,  3,  6;  1,  2,  6 }
+*
+*     A_val = { X; 11, 13; 24, 22, 21; 32, 33; 44, 43, 46; 61, 62, 66 }
+*
+*  PERMUTATION MATRICES
+*
+*  Let P be a permutation matrix of the order n. It is represented as
+*  an integer array P_per of length [1+n+n] as follows: if p[i,j] = 1,
+*  then P_per[i] = j and P_per[n+j] = i. Location P_per[0] is not used.
+*
+*  Let A' = P*A. If i-th row of A corresponds to i'-th row of A', then
+*  P_per[i'] = i and P_per[n+i] = i'.

+*  rgr_write_bmp16 - write 16-color raster image in BMP file format
+*
+*  SYNOPSIS
+*
+*  #include "glprgr.h"
+*  int rgr_write_bmp16(const char *fname, int m, int n, const char
+*     map[]);
+*
+*  DESCRIPTION
+*
+*  The routine rgr_write_bmp16 writes 16-color raster image in
+*  uncompressed BMP file format (Windows bitmap) to a binary file whose
+*  name is specified by the character string fname.
+*
+*  The parameters m and n specify, respectively, the number of rows and
+*  the numbers of columns (i.e. height and width) of the raster image.
+*
+*  The character array map has m*n elements. Elements map[0, ..., n-1]
+*  correspond to the first (top) scanline, elements map[n, ..., 2*n-1]
+*  correspond to the second scanline, etc.
+*
+*  Each element of the array map specifies a color of the corresponding
+*  pixel as 8-bit binary number XXXXIRGB, where four high-order bits (X)
+*  are ignored, I is high intensity bit, R is red color bit, G is green
+*  color bit, and B is blue color bit. Thus, all 16 possible colors are
+*  coded as following hexadecimal numbers:
+*
+*     0x00 = black         0x08 = dark gray
+*     0x01 = blue          0x09 = bright blue
+*     0x02 = green         0x0A = bright green
+*     0x03 = cyan          0x0B = bright cyan
+*     0x04 = red           0x0C = bright red
+*     0x05 = magenta       0x0D = bright magenta
+*     0x06 = brown         0x0E = yellow
+*     0x07 = light gray    0x0F = white
+*
+*  RETURNS
+*
+*  If no error occured, the routine returns zero; otherwise, it prints
+*  an appropriate error message and returns non-zero. */

+*
+*  DESCRIPTION
+*
+*  The routine spm_write_mat writes the specified sparse matrix to a
+*  text file whose name is specified by the parameter fname. This file
+*  can be read back with the routine spm_read_mat.
+*
+*  RETURNS
+*
+*  On success the routine returns zero, otherwise non-zero.
+*
+*  FILE FORMAT
+*
+*  The file created by the routine spm_write_mat is a plain text file,
+*  which contains the following information:
+*
+*     m n nnz
+*     row[1] col[1] val[1]
+*     row[2] col[2] val[2]
+*     . . .
+*     row[nnz] col[nnz] val[nnz]
+*
+*  where:
+*  m is the number of rows;
+*  n is the number of columns;
+*  nnz is the number of non-zeros;
+*  row[k], k = 1,...,nnz, are row indices;

+// LP BASIS AND CURRENT BASIC SOLUTION

+// constraint matrix (7):
+//
+//    (B | N) = (I | -A) * Q,                                        (8)
+//
+// where B is a mxm non-singular basis matrix whose columns correspond
+// to basic variables xB, N is a mxn matrix whose columns correspond to
+// non-basic variables xN, and Q is a permutation (m+n)x(m+n) matrix.
+//
+// From (7) and (8) it follows that
+//
+//    (I | -A) * x = (I | -A) * Q * Q' * x = (B | N) * (xB, xN),
+//
+// therefore
+//
+//    (xB, xN) = Q' * x,                                             (9)
+//
+// where x is the vector of all variables in the original order, xB is
+// a vector of basic variables, xN is a vector of non-basic variables,
+// Q' = inv(Q) is a matrix transposed to Q.
+//
+// Current values of non-basic variables xN[j], j = 1, ..., n, are not
+// stored; they are defined implicitly by their statuses as follows:
+//
+//    0,             if xN[j] is free variable
+//    lN[j],         if xN[j] is on its lower bound                 (10)
+//    uN[j],         if xN[j] is on its upper bound
+//    lN[j] = uN[j], if xN[j] is fixed variable
+//
+// where lN[j] and uN[j] are lower and upper bounds of xN[j].
+//
+// Current values of basic variables xB[i], i = 1, ..., m, are computed
+// as follows:
+//
+//    beta = - inv(B) * N * xN,                                     (11)

+//
+// where B' is a matrix transposed to B, cB is a vector of objective
+// coefficients at basic variables xB.
+//
+// Current values of reduced costs d[j], j = 1, ..., n, (which are
+// values of Langrange multipliers for active inequality constraints
+// corresponding to non-basic variables) are computed as follows:
+//
+//    d = cN - N' * pi,                                             (13)

+*  find_pivot - choose a pivot element
+*
+*  This routine chooses a pivot element v[p,q] in the active submatrix
+*  of matrix U = P*V*Q.
+*
+*  It is assumed that on entry the matrix U has the following partially
+*  triangularized form:
+*
+*        1       k         n
+*     1  x x x x x x x x x x
+*        . x x x x x x x x x
+*        . . x x x x x x x x
+*        . . . x x x x x x x
+*     k  . . . . * * * * * *
+*        . . . . * * * * * *
+*        . . . . * * * * * *
+*        . . . . * * * * * *
+*        . . . . * * * * * *
+*     n  . . . . * * * * * *
+*
+*  where rows and columns k, k+1, ..., n belong to the active submatrix
+*  (elements of the active submatrix are marked by '*').
+*
+*  Since the matrix U = P*V*Q is not stored, the routine works with the
+*  matrix V. It is assumed that the row-wise representation corresponds
+*  to the matrix V, but the column-wise representation corresponds to
+*  the active submatrix of the matrix V, i.e. elements of the matrix V,
+*  which does not belong to the active submatrix, are missing from the
+*  column linked lists. It is also assumed that each active row of the
+*  matrix V is in the set R[len], where len is number of non-zeros in
+*  the row, and each active column of the matrix V is in the set C[len],
+*  where len is number of non-zeros in the column (in the latter case
+*  only elements of the active submatrix are counted; such elements are
+*  marked by '*' on the figure above).
+*
+*  Due to exact arithmetic any non-zero element of the active submatrix
+*  can be chosen as a pivot. However, to keep sparsity of the matrix V
+*  the routine uses Markowitz strategy, trying to choose such element
+*  v[p,q], which has smallest Markowitz cost (nr[p]-1) * (nc[q]-1),
+*  where nr[p] and nc[q] are the number of non-zero elements, resp., in
+*  p-th row and in q-th column of the active submatrix.
+*
+*  In order to reduce the search, i.e. not to walk through all elements
+*  of the active submatrix, the routine exploits a technique proposed by
+*  I.Duff. This technique is based on using the sets R[len] and C[len]
+*  of active rows and columns.
+*
+*  On exit the routine returns a pointer to a pivot v[p,q] chosen, or
+*  NULL, if the active submatrix is empty. */

+*  eliminate - perform gaussian elimination
+*
+*  This routine performs elementary gaussian transformations in order
+*  to eliminate subdiagonal elements in the k-th column of the matrix
+*  U = P*V*Q using the pivot element u[k,k], where k is the number of
+*  the current elimination step.
+*
+*  The parameter piv specifies the pivot element v[p,q] = u[k,k].
+*
+*  Each time when the routine applies the elementary transformation to
+*  a non-pivot row of the matrix V, it stores the corresponding element
+*  to the matrix F in order to keep the main equality A = F*V.
+*
+*  The routine assumes that on entry the matrices L = P*F*inv(P) and
+*  U = P*V*Q are the following:
+*
+*        1       k                  1       k         n
+*     1  1 . . . . . . . . .     1  x x x x x x x x x x
+*        x 1 . . . . . . . .        . x x x x x x x x x
+*        x x 1 . . . . . . .        . . x x x x x x x x
+*        x x x 1 . . . . . .        . . . x x x x x x x
+*     k  x x x x 1 . . . . .     k  . . . . * * * * * *

+*        x x x x _ . . . 1 .        . . . . # * * * * *
+*     n  x x x x _ . . . . 1     n  . . . . # * * * * *
+*
+*             matrix L                   matrix U
+*
+*  where rows and columns of the matrix U with numbers k, k+1, ..., n
+*  form the active submatrix (eliminated elements are marked by '#' and
+*  other elements of the active submatrix are marked by '*'). Note that
+*  each eliminated non-zero element u[i,k] of the matrix U gives the
+*  corresponding element l[i,k] of the matrix L (marked by '_').
+*
+*  Actually all operations are performed on the matrix V. Should note
+*  that the row-wise representation corresponds to the matrix V, but the
+*  column-wise representation corresponds to the active submatrix of the
+*  matrix V, i.e. elements of the matrix V, which doesn't belong to the
+*  active submatrix, are missing from the column linked lists.
+*
+*  Let u[k,k] = v[p,q] be the pivot. In order to eliminate subdiagonal
+*  elements u[i',k] = v[i,q], i' = k+1, k+2, ..., n, the routine applies
+*  the following elementary gaussian transformations:
+*
+*     (i-th row of V) := (i-th row of V) - f[i,p] * (p-th row of V),
+*
+*  where f[i,p] = v[i,q] / v[p,q] is a gaussian multiplier.
+*
+*  Additionally, in order to keep the main equality A = F*V, each time
+*  when the routine applies the transformation to i-th row of the matrix
+*  V, it also adds f[i,p] as a new element to the matrix F.
+*
+*  IMPORTANT: On entry the working arrays flag and work should contain
+*  zeros. This status is provided by the routine on exit. */

+*  lux_decomp - compute LU-factorization
+*
+*  SYNOPSIS
+*
+*  #include "lux.h"
+*  int lux_decomp(LUX *lux, int (*col)(void *info, int j, int ind[],
+*     mpq_t val[]), void *info);
+*
+*  DESCRIPTION
+*
+*  The routine lux_decomp computes LU-factorization of a given square
+*  matrix A.
+*
+*  The parameter lux specifies LU-factorization data structure built by
+*  means of the routine lux_create.
+*
+*  The formal routine col specifies the original matrix A. In order to
+*  obtain j-th column of the matrix A the routine lux_decomp calls the
+*  routine col with the parameter j (1 <= j <= n, where n is the order
+*  of A). In response the routine col should store row indices and
+*  numerical values of non-zero elements of j-th column of A to the
+*  locations ind[1], ..., ind[len] and val[1], ..., val[len], resp.,
+*  where len is the number of non-zeros in j-th column, which should be
+*  returned on exit. Neiter zero nor duplicate elements are allowed.
+*
+*  The parameter info is a transit pointer passed to the formal routine
+*  col; it can be used for various purposes.
+*
+*  RETURNS
+*
+*  The routine lux_decomp returns the singularity flag. Zero flag means
+*  that the original matrix A is non-singular while non-zero flag means
+*  that A is (exactly!) singular.
+*
+*  Note that LU-factorization is valid in both cases, however, in case
+*  of singularity some rows of the matrix V (including pivot elements)
+*  will be empty.
+*
+*  REPAIRING SINGULAR MATRIX
+*
+*  If the routine lux_decomp returns non-zero flag, it provides all
+*  necessary information that can be used for "repairing" the matrix A,
+*  where "repairing" means replacing linearly dependent columns of the
+*  matrix A by appropriate columns of the unity matrix. This feature is
+*  needed when the routine lux_decomp is used for reinverting the basis
+*  matrix within the simplex method procedure.
+*
+*  On exit linearly dependent columns of the matrix U have the numbers
+*  rank+1, rank+2, ..., n, where rank is the exact rank of the matrix A
+*  stored by the routine to the member lux->rank. The correspondence
+*  between columns of A and U is the same as between columns of V and U.
+*  Thus, linearly dependent columns of the matrix A have the numbers
+*  Q_col[rank+1], Q_col[rank+2], ..., Q_col[n], where Q_col is an array
+*  representing the permutation matrix Q in column-like format. It is
+*  understood that each j-th linearly dependent column of the matrix U
+*  should be replaced by the unity vector, where all elements are zero
+*  except the unity diagonal element u[j,j]. On the other hand j-th row
+*  of the matrix U corresponds to the row of the matrix V (and therefore
+*  of the matrix A) with the number P_row[j], where P_row is an array
+*  representing the permutation matrix P in row-like format. Thus, each
+*  j-th linearly dependent column of the matrix U should be replaced by
+*  a column of the unity matrix with the number P_row[j].
+*
+*  The code that repairs the matrix A may look like follows:
+*
+*     for (j = rank+1; j <= n; j++)
+*     {  replace column Q_col[j] of the matrix A by column P_row[j] of
+*        the unity matrix;
+*     }
+*
+*  where rank, P_row, and Q_col are members of the structure LUX. */

+*  The structure LUX defines LU-factorization of a square matrix A,

+*

+*     A = F * V,                                                     (2)
+*
+*  and P and Q are such permutation matrices that the matrix
+*
+*     L = P * F * inv(P)                                             (3)
+*
+*  is lower triangular with unity diagonal, and the matrix
+*
+*     U = P * V * Q                                                  (4)
+*
+*  is upper triangular. All the matrices have the order n.
+*
+*  The matrices F and V are stored in row/column-wise sparse format as
+*  row and column linked lists of non-zero elements. Unity elements on
+*  the main diagonal of the matrix F are not stored. Pivot elements of
+*  the matrix V (that correspond to diagonal elements of the matrix U)
+*  are also missing from the row and column lists and stored separately
+*  in an ordinary array.
+*
+*  The permutation matrices P and Q are stored as ordinary arrays using
+*  both row- and column-like formats.
+*
+*  The matrices L and U being completely defined by the matrices F, V,
+*  P, and Q are not stored explicitly.
+*
+*  It is easy to show that the factorization (1)-(3) is some version of
+*  LU-factorization. Indeed, from (3) and (4) it follows that:
+*
+*     F = inv(P) * L * P,
+*
+*     V = inv(P) * U * inv(Q),
+*
+*  and substitution into (2) gives:
+*
+*     A = F * V = inv(P) * L * U * inv(Q).

+*  glp_open - open stream
+*
+*  SYNOPSIS
+*
+*  glp_file *glp_open(const char *name, const char *mode);
+*
+*  DESCRIPTION
+*
+*  The routine glp_open opens a file whose name is a string pointed to
+*  by name and associates a stream with it.
+*
+*  The following special filenames are recognized by the routine (this
+*  feature is platform independent):
+*
+*  "/dev/null"    empty (null) file;
+*  "/dev/stdin"   standard input stream;
+*  "/dev/stdout"  standard output stream;
+*  "/dev/stderr"  standard error stream.
+*
+*  If the specified filename is ended with ".gz", it is assumed that
+*  the file is in gzipped format. In this case the file is compressed
+*  or decompressed by the I/O routines "on the fly".
+*
+*  The parameter mode points to a string, which indicates the open mode
+*  and should be one of the following:
+*
+*  "r"   open text file for reading;
+*  "w"   truncate to zero length or create text file for writing;
+*  "a"   append, open or create text file for writing at end-of-file;
+*  "rb"  open binary file for reading;
+*  "wb"  truncate to zero length or create binary file for writing;
+*  "ab"  append, open or create binary file for writing at end-of-file.
+*
+*  RETURNS

+*  cfg_expand_clique - expand specified clique to maximal clique
+*
+*  Given some clique in the conflict graph this routine expands it to
+*  a maximal clique by including in it new vertices.
+*
+*  On entry vertex indices constituting the initial clique should be
+*  stored in locations c_ind[1], ..., c_ind[c_len], where c_len is the
+*  initial clique size. On exit the routine stores new vertex indices
+*  to locations c_ind[c_len+1], ..., c_ind[c_len'], where c_len' is the
+*  size of the maximal clique found, and returns c_len'.
+*
+*  ALGORITHM
+*
+*  Let G = (V, E) be a graph, C within V be a current clique to be
+*  expanded, and D within V \ C be a subset of vertices adjacent to all
+*  vertices from C. On every iteration the routine chooses some vertex
+*  v in D, includes it into C, and removes from D the vertex v as well
+*  as all vertices not adjacent to v. Initially C is empty and D = V.
+*  Iterations repeat until D becomes an empty set. Obviously, the final
+*  set C is a maximal clique in G.
+*
+*  Now let C0 be an initial clique, and we want C0 to be a subset of
+*  the final maximal clique C. To provide this condition the routine
+*  starts constructing C by choosing only such vertices v in D, which
+*  are in C0, until all vertices from C0 have been included in C. May
+*  note that if on some iteration C0 \ C is non-empty (i.e. if not all
+*  vertices from C0 have been included in C), C0 \ C is a subset of D,
+*  because C0 is a clique. */

+*  cfg_build_graph - build conflict graph
+*
+*  This routine builds the conflict graph. It analyzes the specified
+*  problem object to discover original and implied packing inequalities
+*  and adds corresponding cliques to the conflict graph.
+*
+*  Packing inequality has the form:
+*
+*      sum z[j] <= 1,                                                (1)
+*     j in J
+*
+*  where z[j] = x[j] or z[j] = 1 - x[j], x[j] is an original binary
+*  variable. Every packing inequality (1) is equivalent to a set of
+*  edge inequalities:
+*
+*     z[i] + z[j] <= 1   for all i, j in J, i != j,                  (2)
+*
+*  and since every edge inequality (2) defines an edge in the conflict
+*  graph, corresponding packing inequality (1) defines a clique.
+*
+*  To discover packing inequalities the routine analyzes constraints
+*  of the specified MIP. To simplify the analysis each constraint is
+*  analyzed separately. The analysis is performed as follows.
+*
+*  Let some original constraint be the following:
+*
+*     L <= sum a[j] x[j] <= U.                                       (3)
+*
+*  To analyze it the routine analyzes two constraints of "not greater
+*  than" type:
+*
+*     sum (-a[j]) x[j] <= -L,                                        (4)
+*
+*     sum (+a[j]) x[j] <= +U,                                        (5)
+*
+*  which are relaxations of the original constraint (3). (If, however,
+*  L = -oo, or U = +oo, corresponding constraint being redundant is not
+*  analyzed.)
+*
+*  Let a constraint of "not greater than" type be the following:
+*
+*      sum  a[j] x[j] + sum  a[j] x[j] <= b,                         (6)
+*     j in J           j in J'
+*
+*  where J is a subset of binary variables, J' is a subset of other
+*  (continues and non-binary integer) variables. The constraint (6) is
+*  is relaxed as follows, to eliminate non-binary variables:
+*
+*      sum  a[j] x[j] <= b -  sum  a[j] x[j] <= b',                  (7)
+*     j in J                 j in J'
+*
+*     b' = sup(b -  sum  a[j] x[j]) =
+*                  j in J'
+*
+*        = b - inf(sum a[j] x[j]) =
+*
+*        = b - sum inf(a[j] x[j]) =                                  (8)
+*
+*        = b -  sum  a[j] inf(x[j]) -  sum  a[j] sup(x[j]) =
+*              a[j]>0                 a[j]<0
+*
+*        = b -  sum  a[j] l[j] -  sum  a[j] u[j],
+*              a[j]>0            a[j]<0
+*
+*  where l[j] and u[j] are, resp., lower and upper bounds of x[j].
+*
+*  Then the routine transforms the relaxed constraint containing only
+*  binary variables:
+*
+*     sum a[j] x[j] <= b                                             (9)
+*
+*  to an equivalent 0-1 knapsack constraint as follows:
+*
+*     sum  a[j] x[j] + sum  a[j] x[j] <= b   ==>
+*    a[j]>0           a[j]<0
+*
+*     sum  a[j] x[j] + sum  a[j] (1 - x[j]) <= b   ==>
+*    a[j]>0           a[j]<0                                        (10)
+*
+*     sum  (+a[j]) x[j] + sum  (-a[j]) x[j] <= b + sum  (-a[j])   ==>
+*    a[j]>0              a[j]<0                   a[j]<0
+*
+*     sum a'[j] z[j] <= b',
+*
+*  where a'[j] = |a[j]| > 0, and
+*
+*            ( x[j]      if a[j] > 0
+*     z[j] = <
+*            ( 1 - x[j]  if a[j] < 0
+*
+*  is a binary variable, which is either original binary variable x[j]
+*  or its complement.
+*
+*  Finally, the routine analyzes the resultant 0-1 knapsack inequality:
+*
+*       sum a[j] z[j] <= b,                                         (11)
+*     j in J
+*
+*  where all a[j] are positive, to discover clique inequalities (1),
+*  which are valid for (11) and therefore valid for (3). (It is assumed
+*  that the original MIP has been preprocessed, so it is not checked,
+*  for example, that b > 0 or that a[j] <= b.)
+*
+*  In principle, to discover any edge inequalities valid for (11) it
+*  is sufficient to check whether a[i] + a[j] > b for all i, j in J,
+*  i < j. However, this way requires O(|J|^2) checks, so the routine
+*  analyses (11) in the following way, which is much more efficient in
+*  many practical cases.
+*
+*  1. Let a[p] and a[q] be two minimal coefficients:
+*
+*     a[p] = min a[j],                                              (12)
+*
+*     a[q] = min a[j], j != p,                                      (13)
+*
+*  such that
+*
+*     a[p] + a[q] > b.                                              (14)
+*
+*  This means that a[i] + a[j] > b for any i, j in J, i != j, so
+*
+*     z[i] + z[j] <= 1                                              (15)
+*
+*  are valid for (11) for any i, j in J, i != j. This case means that
+*  J define a clique in the conflict graph.
+*
+*  2. Otherwise, let a[p] and [q] be two maximal coefficients:
+*
+*     a[p] = max a[j],                                              (16)
+*
+*     a[q] = max a[j], j != p,                                      (17)
+*
+*  such that
+*
+*     a[p] + a[q] <= b.                                             (18)
+*
+*  This means that a[i] + a[j] <= b for any i, j in J, i != j, so in
+*  this case no valid edge inequalities for (11) exist.
+*
+*  3. Otherwise, let all a[j] be ordered by descending their values:
+*
+*     a[1] >= a[2] >= ... >= a[p-1] >= a[p] >= a[p+1] >= ...        (19)
+*
+*  where p is such that
+*
+*     a[p-1] + a[p] >  b,                                           (20)
+*
+*     a[p] + a[p+1] <= b.                                           (21)
+*
+*  (May note that due to the former two cases in this case we always
+*  have 2 <= p <= |J|-1.)
+*
+*  Since a[p] and a[p-1] are two minimal coefficients in the set
+*  J' = {1, ..., p}, J' define a clique in the conflict graph for the
+*  same reason as in the first case. Similarly, since a[p] and a[p+1]
+*  are two maximal coefficients in the set J" = {p, ..., |J|}, no edge
+*  inequalities exist for all i, j in J" for the same reason as in the
+*  second case. Thus, to discover other edge inequalities (15) valid
+*  for (11), the routine checks if a[i] + a[j] > b for all i in J',

+*  cfg_find_clique - find maximum weight clique in conflict graph
+*
+*  This routine finds a maximum weight clique in the conflict graph
+*  G = (V, E), where the weight of vertex v in V is the value of
+*  corresponding binary variable z (which is either an original binary
+*  variable or its complement) in the optimal solution to LP relaxation
+*  provided in the problem object. The goal is to find a clique in G,
+*  whose weight is greater than 1, in which case corresponding packing
+*  inequality is violated at the optimal point.
+*
+*  On exit the routine stores vertex indices of the conflict graph
+*  included in the clique found to locations ind[1], ..., ind[len], and
+*  returns len, which is the clique size. The clique weight is stored
+*  in location pointed to by the parameter sum. If no clique has been
+*  found, the routine returns 0.
+*
+*  Since the conflict graph may have a big number of vertices and be
+*  quite dense, the routine uses an induced subgraph G' = (V', E'),
+*  which is constructed as follows:
+*
+*  1. If the weight of some vertex v in V is zero (close to zero), it
+*     is not included in V'. Obviously, including in a clique
+*     zero-weight vertices does not change its weight, so if in G there
+*     exist a clique of a non-zero weight, in G' exists a clique of the
+*     same weight. This point is extremely important, because dropping
+*     out zero-weight vertices can be done without retrieving lists of
+*     adjacent vertices whose size may be very large.
+*
+*  2. Cumulative weight of vertex v in V is the sum of the weight of v
+*     and weights of all vertices in V adjacent to v. Obviously, if
+*     a clique includes a vertex v, the clique weight cannot be greater
+*     than the cumulative weight of v. Since we are interested only in
+*     cliques whose weight is greater than 1, vertices of V, whose
+*     cumulative weight is not greater than 1, are not included in V'.
+*
+*  May note that in many practical cases the size of the induced
+*  subgraph G' is much less than the size of the original conflict
+*  graph G due to many binary variables, whose optimal values are zero
+*  or close to zero. For example, it may happen that |V| = 100,000 and
+*  |E| = 1e9 while |V'| = 50 and |E'| = 1000. */

+*  a[p] + a[q] > b, then a[i] + a[j] > b for all i != j, from which it
+*  follows that x[i] + x[j] <= 1 for all i != j. But the latter means
+*  that the original inequality (with all a[j] > 0) is equivalent to
+*  packing inequality
+*
+*     sum{j in 1..n} x[j] <= 1.                                      (3)
+*
+*  Returning to original (uncomplemented) variables x'[j] = 1 - x[j]
+*  we have that the original inequality is equivalent to (2), where
+*  J' = {j : a[j] > 0} and J" = {j : a[j] < 0}. */

+*  and which minimizes the left-hand side of (2) at x~
+*
+*     zeta = sum{j in C} (1 - x~[j]).                                (4)
+*
+*  On exit the routine stores the characteritic vector z{j in 1..n}
+*  of the cover found (i.e. z[j] = 1 means j in C, and z[j] = 0 means
+*  j not in C), and returns corresponding minimal value of zeta (4).
+*  However, if no cover is found, the routine returns DBL_MAX.
+*
+*  ALGORITHM
+*
+*  The separation problem (3)-(4) is converted to 0-1 knapsack problem
+*  as follows.
+*
+*  First, note that the constraint (3) is equivalent to
+*
+*     sum{j in 1..n} a[j]z[j] >= b + eps,                            (5)
+*
+*  where eps > 0 is a sufficiently small number (in case of integral
+*  a and b we may take eps = 1). Multiplying both sides of (5) by (-1)
+*  gives
+*
+*     sum{j in 1..n} (-a[j])z[j] <= - b - eps.                       (6)
+*
+*  To make all coefficients in (6) positive, z[j] is complemented by
+*  substitution z[j] = 1 - z'[j] that finally gives
+*
+*     sum{j in 1..n} a[j]z'[j] <= sum{j in 1..n} a[j] - b - eps.     (7)
+*
+*  Minimization of zeta (4) is equivalent to maximization of
+*
+*     -zeta = sum{j in 1..n} (x~[j] - 1)z[j].                        (8)
+*
+*  Substitution z[j] = 1 - z'[j] gives
+*
+*     -zeta = sum{j in 1..n} (1 - x~[j])z'[j] - zeta0,               (9)
+*
+*  where zeta0 = sum{j in 1..n} (1 - x~[j]) is a constant term.
+*
+*  Thus, the 0-1 knapsack problem to be solved is the following:
+*
+*     maximize
+*
+*        -zeta = sum{j in 1..n} (1 - x~[j])z'[j] - zeta0            (10)
+*
+*     subject to
+*
+*        sum{j in 1..n} a[j]z'[j] <= sum{j in 1..n} a[j] - b - eps  (11)
+*
+*        z'[j] in {0,1} for all j = 1,...,n                         (12)
+*
+*  (The constant term zeta0 doesn't affect the solution, so it can be
+*  dropped.) */

+*  NAME
+*
+*  glp_gmi_cut - generate Gomory's mixed integer cut (core routine)
+*
+*  SYNOPSIS
+*
+*  int glp_gmi_cut(glp_prob *P, int j, int ind[], double val[], double
+*     phi[]);
+*
+*  DESCRIPTION
+*
+*  This routine attempts to generate a Gomory's mixed integer cut for
+*  specified integer column (structural variable), whose primal value
+*  in current basic solution is integer infeasible (fractional).
+*
+*  On entry to the routine the basic solution contained in the problem
+*  object P should be optimal, and the basis factorization should be
+*  valid. The parameter j should specify the ordinal number of column
+*  (structural variable x[j]), for which the cut should be generated,
+*  1 <= j <= n, where n is the number of columns in the problem object.
+*  This column should be integer, non-fixed, and basic, and its primal
+*  value should be fractional.
+*
+*  The cut generated by the routine is the following inequality:
+*
+*     sum a[j] * x[j] >= b,
+*
+*  which is expected to be violated at the current basic solution.
+*
+*  If the cut has been successfully generated, the routine stores its
+*  non-zero coefficients a[j] and corresponding column indices j in the
+*  array locations val[1], ..., val[len] and ind[1], ..., ind[len],
+*  where 1 <= len <= n is the number of non-zero coefficients. The
+*  right-hand side value b is stored in val[0], and ind[0] is set to 0.
+*
+*  The working array phi should have 1+m+n locations (location phi[0]
+*  is not used), where m and n is the number of rows and columns in the
+*  problem object, resp.
+*
+*  RETURNS
+*
+*  If the cut has been successfully generated, the routine returns
+*  len, the number of non-zero coefficients in the cut, 1 <= len <= n.
+*
+*  Otherwise, the routine returns one of the following codes:
+*
+*  -1    current basis factorization is not valid;
+*
+*  -2    current basic solution is not optimal;
+*
+*  -3    column ordinal number j is out of range;
+*
+*  -4    variable x[j] is not of integral kind;
+*
+*  -5    variable x[j] is either fixed or non-basic;
+*
+*  -6    primal value of variable x[j] in basic solution is too close
+*        to nearest integer;
+*
+*  -7    some coefficients in the simplex table row corresponding to
+*        variable x[j] are too large in magnitude;
+*
+*  -8    some free (unbounded) variables have non-zero coefficients in
+*        the simplex table row corresponding to variable x[j].
+*
+*  ALGORITHM
+*
+*  See glpk/doc/notes/gomory (in Russian). */

+*  integer infeasible (fractional).
+*
+*  On entry to the routine the basic solution contained in the problem
+*  object P should be optimal, and the basis factorization should be
+*  valid.
+*
+*  The cutting plane inequalities generated by the routine are added to
+*  the specified cut pool.
+*
+*  The parameter max_cuts specifies the maximal number of cuts to be
+*  generated. Note that the number of cuts cannot exceed the number of
+*  basic variables, which is the number of rows in the problem object.
+*
+*  RETURNS
+*
+*  The routine returns the number of cuts that have been generated and
+*  added to the cut pool. */

+Subject: Mir cut generation performance improvement
+From: Chris Matrakidis <cmatraki@gmail.com>
+To: Andrew Makhorin <mao@gnu.org>, help-glpk <help-glpk@gnu.org>
+
+Andrew,
+
+I noticed that mir cut generation takes considerable time on some large
+problems (like rocII-4-11 from miplib). The attached patch makes two
+improvements that considerably improve performance in such instances:
+1. A lot of time was spent on generating a temporary vector in function
+aggregate_row. It is a lot faster to reuse an existing vector.
+2. A search for an element in the same function was done in row order,
+where using the elements in the order they are in the column is more
+efficient. This changes the generated cuts in some cases, but seems
+neutral overall (0.3% less cuts in a test set of 64 miplib instances).
+
+Best Regards,
+
+Chris Matrakidis

+MiniSat-C v1.14.1
+========================================
+
+* Fixed some serious bugs.
+* Tweaked to be Visual Studio friendly (by Alan Mishchenko).
+  This disabled reading of gzipped DIMACS files and signal handling,
+  but none of these features are essential (and easy to re-enable, if
+  wanted).
+
+MiniSat-C v1.14
+========================================
+
+Ok, we get it. You hate C++. You hate templates. We agree; C++ is a
+seriously messed up language. Although we are more pragmatic about the
+quirks and maldesigns in C++, we sympathize with you. So here is a
+pure C version of MiniSat, put together by Niklas Sorensson.

+*
+*  y is an array containing digits of the divisor in elements y[0],
+*  y[1], ..., y[m-1]. The highest digit y[m-1] must be non-zero.
+*
+*  On exit n+1 digits of the quotient are stored in elements x[m],
+*  x[m+1], ..., x[n+m], and m digits of the remainder are stored in

+*  void ffalg(int nv, int na, const int tail[], const int head[],
+*     int s, int t, const int cap[], int x[], char cut[]);
+*
+*  DESCRIPTION
+*
+*  The routine ffalg implements the Ford-Fulkerson algorithm to find a
+*  maximal flow in the specified flow network.
+*
+*  INPUT PARAMETERS
+*
+*  nv is the number of nodes, nv >= 2.
+*
+*  na is the number of arcs, na >= 0.
+*
+*  tail[a], a = 1,...,na, is the index of tail node of arc a.
+*
+*  head[a], a = 1,...,na, is the index of head node of arc a.
+*
+*  s is the source node index, 1 <= s <= nv.
+*
+*  t is the sink node index, 1 <= t <= nv, t != s.
+*
+*  cap[a], a = 1,...,na, is the capacity of arc a, cap[a] >= 0.
+*
+*  NOTE: Multiple arcs are allowed, but self-loops are not allowed.
+*
+*  OUTPUT PARAMETERS
+*
+*  x[a], a = 1,...,na, is optimal value of the flow through arc a.
+*
+*  cut[i], i = 1,...,nv, is 1 if node i is labelled, and 0 otherwise.
+*  The set of arcs, whose one endpoint is labelled and other is not,
+*  defines the minimal cut corresponding to the maximal flow found.
+*  If the parameter cut is NULL, the cut information are not stored.

+*  NAME
+*
+*  fp2rat - convert floating-point number to rational number
+*
+*  SYNOPSIS
+*
+*  #include "misc.h"
+*  int fp2rat(double x, double eps, double *p, double *q);
+*
+*  DESCRIPTION
+*
+*  Given a floating-point number 0 <= x < 1 the routine fp2rat finds
+*  its "best" rational approximation p / q, where p >= 0 and q > 0 are
+*  integer numbers, such that |x - p / q| <= eps.
+*
+*  RETURNS
+*
+*  The routine fp2rat returns the number of iterations used to achieve
+*  the specified precision eps.
+*
+*  EXAMPLES
+*
+*  For x = sqrt(2) - 1 = 0.414213562373095 and eps = 1e-6 the routine
+*  gives p = 408 and q = 985, where 408 / 985 = 0.414213197969543.
+*
+*  BACKGROUND
+*
+*  It is well known that every positive real number x can be expressed
+*  as the following continued fraction:
+*
+*     x = b[0] + a[1]
+*                ------------------------
+*                b[1] + a[2]
+*                       -----------------
+*                       b[2] + a[3]
+*                              ----------
+*                              b[3] + ...
+*
+*  where:
+*
+*     a[k] = 1,                  k = 0, 1, 2, ...
+*
+*     b[k] = floor(x[k]),        k = 0, 1, 2, ...
+*
+*     x[0] = x,
+*
+*     x[k] = 1 / frac(x[k-1]),   k = 1, 2, 3, ...
+*
+*  To find the "best" rational approximation of x the routine computes
+*  partial fractions f[k] by dropping after k terms as follows:
+*
+*     f[k] = A[k] / B[k],
+*
+*  where:
+*
+*     A[-1] = 1,   A[0] = b[0],   B[-1] = 0,   B[0] = 1,
+*
+*     A[k] = b[k] * A[k-1] + a[k] * A[k-2],
+*
+*     B[k] = b[k] * B[k-1] + a[k] * B[k-2].
+*
+*  Once the condition
+*
+*     |x - f[k]| <= eps
+*
+*  has been satisfied, the routine reports p = A[k] and q = B[k] as the
+*  final answer.
+*
+*  In the table below here is some statistics obtained for one million
+*  random numbers uniformly distributed in the range [0, 1).
+*
+*      eps      max p   mean p      max q    mean q  max k   mean k

+*  NAME
+*
+*  kellerman - cover edges by cliques with Kellerman's heuristic
+*
+*  SYNOPSIS
+*
+*  #include "keller.h"
+*  int kellerman(int n, int (*func)(void *info, int i, int ind[]),
+*     void *info, glp_graph *H);
+*
+*  DESCRIPTION
+*
+*  The routine kellerman implements Kellerman's heuristic algorithm
+*  to find a minimal set of cliques which cover all edges of specified
+*  graph G = (V, E).
+*
+*  The parameter n specifies the number of vertices |V|, n >= 0.
+*
+*  Formal routine func specifies the set of edges E in the following
+*  way. Running the routine kellerman calls the routine func and passes
+*  to it parameter i, which is the number of some vertex, 1 <= i <= n.
+*  In response the routine func should store numbers of all vertices
+*  adjacent to vertex i to locations ind[1], ind[2], ..., ind[len] and
+*  return the value of len, which is the number of adjacent vertices,
+*  0 <= len <= n. Self-loops are allowed, but ignored. Multiple edges
+*  are not allowed.
+*
+*  The parameter info is a transit pointer (magic cookie) passed to the
+*  formal routine func as its first parameter.
+*
+*  The result provided by the routine kellerman is the bipartite graph
+*  H = (V union C, F), which defines the covering found. (The program
+*  object of type glp_graph specified by the parameter H should be
+*  previously created with the routine glp_create_graph. On entry the
+*  routine kellerman erases the content of this object with the routine
+*  glp_erase_graph.) Vertices of first part V correspond to vertices of
+*  the graph G and have the same ordinal numbers 1, 2, ..., n. Vertices
+*  of second part C correspond to cliques and have ordinal numbers
+*  n+1, n+2, ..., n+k, where k is the total number of cliques in the
+*  edge covering found. Every edge f in F in the program object H is
+*  represented as arc f = (i->j), where i in V and j in C, which means
+*  that vertex i of the graph G is in clique C[j], 1 <= j <= k. (Thus,
+*  if two vertices of the graph G are in the same clique, these vertices
+*  are adjacent in G, and corresponding edge is covered by that clique.)
+*
+*  RETURNS
+*
+*  The routine Kellerman returns k, the total number of cliques in the
+*  edge covering found.
+*
+*  REFERENCE
+*
+*  For more details see: glpk/doc/notes/keller.pdf (in Russian). */

+*  NAME
+*
+*  mc13d - permutations to block triangular form
+*
+*  SYNOPSIS
+*
+*  #include "mc13d.h"
+*  int mc13d(int n, const int icn[], const int ip[], const int lenr[],
+*     int ior[], int ib[], int lowl[], int numb[], int prev[]);
+*
+*  DESCRIPTION
+*
+*  Given the column numbers of the nonzeros in each row of the sparse
+*  matrix, the routine mc13d finds a symmetric permutation that makes
+*  the matrix block lower triangular.
+*
+*  INPUT PARAMETERS
+*
+*  n     order of the matrix.
+*
+*  icn   array containing the column indices of the non-zeros. Those
+*        belonging to a single row must be contiguous but the ordering
+*        of column indices within each row is unimportant and wasted
+*        space between rows is permitted.
+*
+*  ip    ip[i], i = 1,2,...,n, is the position in array icn of the
+*        first column index of a non-zero in row i.
+*
+*  lenr  lenr[i], i = 1,2,...,n, is the number of non-zeros in row i.
+*
+*  OUTPUT PARAMETERS
+*
+*  ior   ior[i], i = 1,2,...,n, gives the position on the original
+*        ordering of the row or column which is in position i in the
+*        permuted form.
+*
+*  ib    ib[i], i = 1,2,...,num, is the row number in the permuted
+*        matrix of the beginning of block i, 1 <= num <= n.
+*
+*  WORKING ARRAYS
+*
+*  arp   working array of length [1+n], where arp[0] is not used.
+*        arp[i] is one less than the number of unsearched edges leaving
+*        node i. At the end of the algorithm it is set to a permutation
+*        which puts the matrix in block lower triangular form.
+*
+*  ib    working array of length [1+n], where ib[0] is not used.
+*        ib[i] is the position in the ordering of the start of the ith
+*        block. ib[n+1-i] holds the node number of the ith node on the
+*        stack.
+*
+*  lowl  working array of length [1+n], where lowl[0] is not used.
+*        lowl[i] is the smallest stack position of any node to which a
+*        path from node i has been found. It is set to n+1 when node i
+*        is removed from the stack.
+*
+*  numb  working array of length [1+n], where numb[0] is not used.
+*        numb[i] is the position of node i in the stack if it is on it,
+*        is the permuted order of node i for those nodes whose final
+*        position has been found and is otherwise zero.
+*
+*  prev  working array of length [1+n], where prev[0] is not used.
+*        prev[i] is the node at the end of the path when node i was
+*        placed on the stack.
+*
+*  RETURNS
+*
+*  The routine mc13d returns num, the number of blocks found. */

+*
+*  SYNOPSIS
+*
+*  #include "mc21a.h"
+*  int mc21a(int n, const int icn[], const int ip[], const int lenr[],
+*     int iperm[], int pr[], int arp[], int cv[], int out[]);
+*
+*  DESCRIPTION
+*
+*  Given the pattern of nonzeros of a sparse matrix, the routine mc21a
+*  attempts to find a permutation of its rows that makes the matrix have
+*  no zeros on its diagonal.
+*
+*  INPUT PARAMETERS
+*
+*  n     order of matrix.
+*
+*  icn   array containing the column indices of the non-zeros. Those
+*        belonging to a single row must be contiguous but the ordering
+*        of column indices within each row is unimportant and wasted
+*        space between rows is permitted.
+*
+*  ip    ip[i], i = 1,2,...,n, is the position in array icn of the
+*        first column index of a non-zero in row i.
+*
+*  lenr  lenr[i], i = 1,2,...,n, is the number of non-zeros in row i.
+*
+*  OUTPUT PARAMETER
+*
+*  iperm contains permutation to make diagonal have the smallest
+*        number of zeros on it. Elements (iperm[i], i), i = 1,2,...,n,
+*        are non-zero at the end of the algorithm unless the matrix is
+*        structurally singular. In this case, (iperm[i], i) will be
+*        zero for n - numnz entries.
+*
+*  WORKING ARRAYS
+*
+*  pr    working array of length [1+n], where pr[0] is not used.
+*        pr[i] is the previous row to i in the depth first search.
+*
+*  arp   working array of length [1+n], where arp[0] is not used.
+*        arp[i] is one less than the number of non-zeros in row i which
+*        have not been scanned when looking for a cheap assignment.
+*
+*  cv    working array of length [1+n], where cv[0] is not used.
+*        cv[i] is the most recent row extension at which column i was
+*        visited.
+*
+*  out   working array of length [1+n], where out[0] is not used.
+*        out[i] is one less than the number of non-zeros in row i
+*        which have not been scanned during one pass through the main
+*        loop.
+*
+*  RETURNS
+*
+*  The routine mc21a returns numnz, the number of non-zeros on diagonal
+*  of permuted matrix. */

+      SUBROUTINE MT1(N,P,W,C,Z,X,JDIM,JCK,XX,MIN,PSIGN,WSIGN,ZSIGN)
+C
+C THIS SUBROUTINE SOLVES THE 0-1 SINGLE KNAPSACK PROBLEM
+C
+C MAXIMIZE  Z = P(1)*X(1) + ... + P(N)*X(N)
+C
+C SUBJECT TO:   W(1)*X(1) + ... + W(N)*X(N) .LE. C ,
+C               X(J) = 0 OR 1  FOR J=1,...,N.
+C
+C THE PROGRAM IS INCLUDED IN THE VOLUME
+C   S. MARTELLO, P. TOTH, "KNAPSACK PROBLEMS: ALGORITHMS
+C   AND COMPUTER IMPLEMENTATIONS", JOHN WILEY, 1990
+C AND IMPLEMENTS THE BRANCH-AND-BOUND ALGORITHM DESCRIBED IN
+C SECTION  2.5.2 .
+C THE PROGRAM DERIVES FROM AN EARLIER CODE PRESENTED IN
+C  S. MARTELLO, P. TOTH, "ALGORITHM FOR THE SOLUTION OF THE 0-1 SINGLE
+C  KNAPSACK PROBLEM", COMPUTING, 1978.
+C
+C THE INPUT PROBLEM MUST SATISFY THE CONDITIONS
+C
+C   1) 2 .LE. N .LE. JDIM - 1 ;
+C   2) P(J), W(J), C  POSITIVE INTEGERS;
+C   3) MAX (W(J)) .LE. C ;

+C   5) P(J)/W(J) .GE. P(J+1)/W(J+1) FOR J=1,...,N-1.
+C
+C MT1 CALLS  1  PROCEDURE: CHMT1.
+C
+C THE PROGRAM IS COMPLETELY SELF-CONTAINED AND COMMUNICATION TO IT IS
+C ACHIEVED SOLELY THROUGH THE PARAMETER LIST OF MT1.
+C NO MACHINE-DEPENDENT CONSTANT IS USED.
+C THE PROGRAM IS WRITTEN IN 1967 AMERICAN NATIONAL STANDARD FORTRAN
+C AND IS ACCEPTED BY THE PFORT VERIFIER (PFORT IS THE PORTABLE
+C SUBSET OF ANSI DEFINED BY THE ASSOCIATION FOR COMPUTING MACHINERY).
+C THE PROGRAM HAS BEEN TESTED ON A DIGITAL VAX 11/780 AND AN H.P.
+C 9000/840.
+C
+C MT1 NEEDS  8  ARRAYS ( P ,  W ,  X ,  XX ,  MIN ,  PSIGN ,  WSIGN
+C                        AND  ZSIGN ) OF LENGTH AT LEAST  N + 1 .

+C MEANING OF THE INPUT PARAMETERS:
+C N    = NUMBER OF ITEMS;
+C P(J) = PROFIT OF ITEM  J  (J=1,...,N);
+C W(J) = WEIGHT OF ITEM  J  (J=1,...,N);
+C C    = CAPACITY OF THE KNAPSACK;
+C JDIM = DIMENSION OF THE 8 ARRAYS;
+C JCK  = 1 IF CHECK ON THE INPUT DATA IS DESIRED,
+C      = 0 OTHERWISE.
+C
+C MEANING OF THE OUTPUT PARAMETERS:
+C Z    = VALUE OF THE OPTIMAL SOLUTION IF  Z .GT. 0 ,
+C      = ERROR IN THE INPUT DATA (WHEN JCK=1) IF Z .LT. 0 : CONDI-
+C        TION  - Z  IS VIOLATED;
+C X(J) = 1 IF ITEM  J  IS IN THE OPTIMAL SOLUTION,
+C      = 0 OTHERWISE.
+C
+C ARRAYS XX, MIN, PSIGN, WSIGN AND ZSIGN ARE DUMMY.

+*  INTEGER NUMBERS
+*  ---------------
+*  Depending on its magnitude an integer number of arbitrary precision
+*  is represented either in short format or in long format.
+*
+*  Short format corresponds to the int type and allows representing
+*  integer numbers in the range [-(2^31-1), +(2^31-1)]. Note that for
+*  the most negative number of int type the short format is not used.
+*
+*  In long format integer numbers are represented using the positional

+*  NAME
+*
+*  okalg - out-of-kilter algorithm
+*
+*  SYNOPSIS
+*
+*  #include "okalg.h"
+*  int okalg(int nv, int na, const int tail[], const int head[],
+*     const int low[], const int cap[], const int cost[], int x[],
+*     int pi[]);
+*
+*  DESCRIPTION
+*
+*  The routine okalg implements the out-of-kilter algorithm to find a
+*  minimal-cost circulation in the specified flow network.
+*
+*  INPUT PARAMETERS
+*
+*  nv is the number of nodes, nv >= 0.
+*
+*  na is the number of arcs, na >= 0.
+*
+*  tail[a], a = 1,...,na, is the index of tail node of arc a.
+*
+*  head[a], a = 1,...,na, is the index of head node of arc a.
+*
+*  low[a], a = 1,...,na, is an lower bound to the flow through arc a.
+*
+*  cap[a], a = 1,...,na, is an upper bound to the flow through arc a,
+*  which is the capacity of the arc.
+*
+*  cost[a], a = 1,...,na, is a per-unit cost of the flow through arc a.
+*
+*  NOTES
+*
+*  1. Multiple arcs are allowed, but self-loops are not allowed.
+*
+*  2. It is required that 0 <= low[a] <= cap[a] for all arcs.
+*
+*  3. Arc costs may have any sign.
+*
+*  OUTPUT PARAMETERS
+*
+*  x[a], a = 1,...,na, is optimal value of the flow through arc a.
+*
+*  pi[i], i = 1,...,nv, is Lagrange multiplier for flow conservation
+*  equality constraint corresponding to node i (the node potential).
+*
+*  RETURNS
+*
+*  0  optimal circulation found;
+*
+*  1  there is no feasible circulation;
+*
+*  2  integer overflow occured;
+*
+*  3  optimality test failed (logic error).

+*  genqmd - GENeral Quotient Minimum Degree algorithm
+*
+*  SYNOPSIS
+*
+*  #include "qmd.h"
+*  void genqmd(int *neqns, int xadj[], int adjncy[], int perm[],
+*     int invp[], int deg[], int marker[], int rchset[], int nbrhd[],
+*     int qsize[], int qlink[], int *nofsub);
+*
+*  PURPOSE
+*
+*  This routine implements the minimum degree algorithm. It makes use
+*  of the implicit representation of the elimination graph by quotient
+*  graphs, and the notion of indistinguishable nodes.
+*
+*  CAUTION
+*
+*  The adjancy vector adjncy will be destroyed.
+*
+*  INPUT PARAMETERS
+*
+*  neqns  - number of equations;
+*  (xadj, adjncy) -
+*           the adjancy structure.
+*
+*  OUTPUT PARAMETERS
+*
+*  perm   - the minimum degree ordering;
+*  invp   - the inverse of perm.
+*
+*  WORKING PARAMETERS
+*
+*  deg    - the degree vector. deg[i] is negative means node i has been
+*           numbered;
+*  marker - a marker vector, where marker[i] is negative means node i
+*           has been merged with another nodeand thus can be ignored;
+*  rchset - vector used for the reachable set;
+*  nbrhd  - vector used for neighborhood set;
+*  qsize  - vector used to store the size of indistinguishable
+*           supernodes;
+*  qlink  - vector used to store indistinguishable nodes, i, qlink[i],
+*           qlink[qlink[i]], ... are the members of the supernode
+*           represented by i.

+/***********************************************************************
+*  WARNING
+*
+*  A serious bug was *tentatively* fixed in this code (see #if/#endif
+*  marked by 'mao').
+*
+*  This bug is inherited from the original Fortran version of the
+*  RELAX-IV code. Unfortunately, the code is very intricate, so this
+*  bug is still under investigation. Thanks to Sylvain Fournier for bug
+*  report.
+*
+*  RELAX-IV bug details
+*  --------------------
+*  In the original RELAX-IV code there are four similar fragments in
+*  subroutines ascnt1 and ascnt2 like this:
+*
+*  C
+*  C     DECREASE THE PRICES OF THE SCANNED NODES BY DELPRC.
+*  C     ADJUST FLOW TO MAINTAIN COMPLEMENTARY SLACKNESS WITH
+*  C     THE PRICES.
+*  C
+*        NB = 0
+*        DO 6 I=1,NSAVE
+*        . . .
+*           IF (RC(ARC).EQ.0) THEN
+*              DELX=DELX+U(ARC)
+*              NB = NB + 1
+*              PRDCSR(NB) = ARC
+*           END IF
+*        . . .
+*
+*  On some instances the variable NB becomes greater than N (the number
+*  of nodes) that leads to indexing error, because the array PRDCSR is
+*  declared as array of N elements (more precisely, as array of MAXNN
+*  elements, however, NB becomes even much greater than MAXNN).

+*  RELAX-IV (version of October 1994)
+*
+*  PURPOSE
+*
+*  This routine implements the relaxation method of Bertsekas and Tseng
+*  (see [1], [2]) for linear cost ordinary network flow problems.
+*
+*  [1] Bertsekas, D. P., "A Unified Framework for Primal-Dual Methods"
+*      Mathematical Programming, Vol. 32, 1985, pp. 125-145.
+*  [2] Bertsekas, D. P., and Tseng, P., "Relaxation Methods for
+*      Minimum Cost" Operations Research, Vol. 26, 1988, pp. 93-114.
+*
+*  The relaxation method is also described in the books:
+*
+*  [3] Bertsekas, D. P., "Linear Network Optimization: Algorithms and
+*      Codes" MIT Press, 1991.
+*  [4] Bertsekas, D. P. and Tsitsiklis, J. N., "Parallel and Distributed

+*  [5] Bertsekas, D. P., "Network Optimization: Continuous and Discrete
+*      Models", Athena Scientific, 1998.
+*
+*  RELEASE NOTE
+*
+*  This version of relaxation code has option for a special crash
+*  procedure for the initial price-flow pair. This is recommended for
+*  difficult problems where the default initialization results in long
+*  running times. crash = 1 corresponds to an auction/shortest path
+*  method
+*
+*  These initializations are recommended in the absence of any prior
+*  information on a favorable initial flow-price vector pair that
+*  satisfies complementary slackness.
+*
+*  The relaxation portion of the code differs from the code RELAXT-III
+*  and other earlier relaxation codes in that it maintains the set of
+*  nodes with nonzero deficit in a fifo queue. Like its predecessor
+*  RELAXT-III, this code maintains a linked list of balanced (i.e., of
+*  zero reduced cost) arcs so to reduce the work in labeling and
+*  scanning. Unlike RELAXT-III, it does not use selectively shortest
+*  path iterations for initialization.
+*
+*  SOURCE
+*
+*  The original Fortran code was written by Dimitri P. Bertsekas and
+*  Paul Tseng, with a contribution by Jonathan Eckstein in the phase II
+*  initialization. The original Fortran routine AUCTION was written by
+*  Dimitri P. Bertsekas and is based on the method described in the
+*  paper:
+*
+*  [6] Bertsekas, D. P., "An Auction/Sequential Shortest Path Algorithm
+*      for the Minimum Cost Flow Problem", LIDS Report P-2146, MIT,

+*  NOTE 2
+*
+*  This routine makes no effort to initialize with a favorable x from

+*  to this routine directly. This, however, requires that the capacity
+*  tightening portion and the flow initialization portion of this
+*  routine (up to line labeled 90) be skipped.
+*
+*  NOTE 3
+*
+*  All problem data should be less than large in magnitude, and large
+*  should be less than, say, 1/4 the largest int of the machine used.
+*  This will guard primarily against overflow in uncapacitated problems
+*  where the arc capacities are taken finite but very large. Note,
+*  however, that as in all codes operating with integers, overflow may
+*  occur if some of the problem data takes very large values.
+*
+*  NOTE 4
+*
+*  [This note being specific to Fortran was removed.-A.M.]
+*
+*  NOTE 5
+*
+*  ddpos and ddneg are arrays that give the directional derivatives for
+*  all positive and negative single-node price changes. These are used
+*  only in phase II of the initialization procedure, before the linked
+*  list of balanced arcs comes to play. Therefore, to reduce storage,
+*  they are equivalence to tfstou and tfstin, which are of the same size
+*  (number of nodes) and are used only after the tree comes into use. */

+*  NAME
+*
+*  ascnt1 - multi-node price adjustment for positive deficit case
+*
+*  PURPOSE
+*
+*  This subroutine performs the multi-node price adjustment step for
+*  the case where the scanned nodes have positive deficit. It first
+*  checks if decreasing the price of the scanned nodes increases the
+*  dual cost. If yes, then it decreases the price of all scanned nodes.
+*  There are two possibilities for price decrease: if switch = true,
+*  then the set of scanned nodes corresponds to an elementary direction
+*  of maximal rate of ascent, in which case the price of all scanned
+*  nodes are decreased until the next breakpoint in the dual cost is
+*  encountered. At this point, some arc becomes balanced and more
+*  node(s) are added to the labeled set and the subroutine is exited.
+*  If switch = false, then the price of all scanned nodes are decreased
+*  until the rate of ascent becomes negative (this corresponds to the
+*  price adjustment step in which both the line search and the
+*  degenerate ascent iteration are implemented).

+*  triang - find maximal triangular part of rectangular matrix
+*
+*  Given a mxn sparse matrix A this routine finds permutation matrices
+*  P and Q such that matrix A' = P * A * Q has the following structure:
+*
+*        1         s         n
+*     1  * . . . . . x x x x x
+*        * * . . . . x x x x x
+*        * * * . . . x x x x x
+*        * * * * . . x x x x x
+*        * * * * * . x x x x x
+*     s  * * * * * * x x x x x
+*        x x x x x x x x x x x
+*        x x x x x x x x x x x
+*     m  x x x x x x x x x x x
+*
+*  where '*' are elements of the triangular part, '.' are structural
+*  zeros, 'x' are other elements.
+*
+*  The formal routine mat specifies the original matrix A in both row-
+*  and column-wise format. If the routine mat is called with k = +i,
+*  1 <= i <= m, it should store column indices and values of non-zero
+*  elements of i-th row of A in locations ind[1], ..., ind[len] and
+*  val[1], ..., val[len], resp., where len is the returned number of
+*  non-zeros in the row, 0 <= len <= n. Similarly, if the routine mat
+*  is called with k = -j, 1 <= j <= n, it should store row indices and
+*  values of non-zero elements of j-th column of A and return len, the
+*  number of non-zeros in the column, 0 <= len <= m. Should note that
+*  duplicate indices are not allowed.
+*
+*  The parameter info is a transit pointer passed to the routine mat.
+*
+*  The parameter tol is a tolerance. The routine triang guarantees that
+*  each diagonal element in the triangular part of matrix A' is not
+*  less in magnitude than tol * max, where max is the maximal magnitude
+*  of elements in corresponding column.
+*
+*  On exit the routine triang stores information on the triangular part
+*  found in the arrays rn and cn. Elements rn[1], ..., rn[s] specify
+*  row numbers and elements cn[1], ..., cn[s] specify column numbers
+*  of the original matrix A, which correspond to rows/columns 1, ..., s
+*  of matrix A', where s is the size of the triangular part returned by
+*  the routine, 0 <= s <= min(m, n). The order of rows and columns that
+*  are not included in the triangular part remains unspecified.
+*
+*  ALGORITHM
+*
+*  The routine triang uses a simple greedy heuristic.
+*
+*  At some step the matrix A' = P * A * Q has the following structure:
+*
+*        1                   n
+*     1  * . . . . . . . x x x
+*        * * . . . . . . x x x
+*        * * * . . . . . x x x
+*        * * * * . . . . x x x
+*        x x x x # # # # x x x
+*        x x x x # # # # x x x
+*        x x x x # # # # x x x
+*        x x x x # # # # x x x
+*     m  x x x x # # # # x x x
+*
+*  where '#' are elements of active submatrix. Initially P = Q = I, so
+*  the active submatrix is the original matrix A = A'.
+*
+*  If some row has exactly one non-zero in the active submatrix (row
+*  singleton), the routine includes this row and corresponding column
+*  in the triangular part, and removes the column from the active
+*  submatrix. Otherwise, the routine simply removes a column having
+*  maximal number of non-zeros from the active submatrix in the hope
+*  that new row singleton(s) will appear.
+*
+*  COMPLEXITY
+*
+*  The time complexity of the routine triang is O(nnz), where nnz is
+*  number of non-zeros in the original matrix A. */

+*  int wclique1(int n, const double w[],
+*     int (*func)(void *info, int i, int ind[]), void *info, int c[]);
+*
+*  DESCRIPTION
+*
+*  The routine wclique1 implements a sequential greedy heuristic to
+*  find maximum weight clique in a given (undirected) graph G = (V, E).
+*
+*  The parameter n specifies the number of vertices |V| in the graph,
+*  n >= 0.
+*
+*  The array w specifies vertex weights in locations w[i], i = 1,...,n.
+*  All weights must be non-negative.
+*
+*  The formal routine func specifies the graph. For a given vertex i,
+*  1 <= i <= n, it stores indices of all vertices adjacent to vertex i
+*  in locations ind[1], ..., ind[deg], where deg is the degree of
+*  vertex i, 0 <= deg < n, returned on exit. Note that self-loops and
+*  multiple edges are not allowed.
+*
+*  The parameter info is a cookie passed to the routine func.
+*
+*  On exit the routine wclique1 stores vertex indices included in
+*  the clique found to locations c[1], ..., c[size], where size is the
+*  clique size returned by the routine, 0 <= size <= n.
+*
+*  RETURNS
+*
+*  The routine wclique1 returns the size of the clique found. */

+*
+*  DESCRIPTION
+*
+*  The routine db_iodbc_open opens a connection to an ODBC data base.
+*  It then executes the sql statements passed.
+*
+*  In the case of table read the SELECT statement is executed.
+*
+*  In the case of table write the INSERT statement is prepared.
+*  RETURNS
+*
+*  The routine returns a pointer to data storage area created. */

+*
+*  The routine npp_geq_row processes row p, which is 'not less than'
+*  inequality constraint:

+*
+*  The routine npp_lbnd_col processes column q, which has (non-zero)

+*
+*  is a non-negative variable.

+*
+*  1. Formally, in solution to the transformed problem columns q and s
+*     cannot be non-basic at the same time, since the constraint (2)
+*     would be violated. However, if u[q] is close to zero, violation
+*     may be less than a working precision even if both columns q and s
+*     are non-basic. In this degenerate case row (2) can be only basic,
+*     i.e. non-active constraint (otherwise corresponding row of the
+*     basis matrix would be zero). This allows to pivot out auxiliary
+*     variable and pivot in column s, in which case the row becomes

+*  void npp_fixed_col(NPP *npp, NPPCOL *q);
+*
+*  DESCRIPTION
+*
+*  The routine npp_fixed_col processes column q, which is fixed:
+*
+*     x[q] = s[q],                                                   (1)
+*
+*  where s[q] is a fixed column value.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  The value of a fixed column can be substituted into the objective
+*  and constraint rows that allows removing the column from the problem.
+*
+*  Substituting x[q] = s[q] into the objective row, we have:
+*
+*     z = sum c[j] x[j] + c0 =
+*          j
+*
+*       = sum c[j] x[j] + c[q] x[q] + c0 =
+*         j!=q
+*
+*       = sum c[j] x[j] + c[q] s[q] + c0 =
+*         j!=q
+*
+*       = sum c[j] x[j] + c~0,
+*         j!=q
+*
+*  where
+*
+*     c~0 = c0 + c[q] s[q]                                           (2)
+*
+*  is the constant term of the objective in the transformed problem.
+*  Similarly, substituting x[q] = s[q] into constraint row i, we have:
+*
+*     L[i] <= sum a[i,j] x[j] <= U[i]  ==>
+*              j
+*
+*     L[i] <= sum a[i,j] x[j] + a[i,q] x[q] <= U[i]  ==>

+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_empty_col(NPP *npp, NPPCOL *q);
+*
+*  DESCRIPTION
+*
+*  The routine npp_empty_col processes column q:
+*
+*     l[q] <= x[q] <= u[q],                                          (1)
+*
+*  where l[q] <= u[q], which is empty, i.e. has zero coefficients in
+*  all constraint rows.
+*
+*  RETURNS
+*
+*  0 - success;
+*
+*  1 - problem has no dual feasible solution.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  The row of the dual system corresponding to the empty column is the
+*  following:
+*
+*     sum 0 pi[i] + lambda[q] = c[q],                                (2)
+*      i
+*
+*  from which it follows that:
+*
+*     lambda[q] = c[q].                                              (3)
+*
+*  If the following condition holds:
+*
+*     c[q] < - eps,                                                  (4)
+*
+*  where eps is an absolute tolerance for column multiplier, the lower
+*  column bound l[q] must be active to provide dual feasibility (note
+*  that being preprocessed the problem is always minimization). In this
+*  case the column can be fixed on its lower bound and removed from the
+*  problem (if the column is integral, its bounds are also assumed to
+*  be integral). And if the column has no lower bound (l[q] = -oo), the
+*  problem has no dual feasible solution.
+*
+*  If the following condition holds:
+*
+*     c[q] > + eps,                                                  (5)
+*
+*  the upper column bound u[q] must be active to provide dual
+*  feasibility. In this case the column can be fixed on its upper bound
+*  and removed from the problem. And if the column has no upper bound
+*  (u[q] = +oo), the problem has no dual feasible solution.
+*
+*  Finally, if the following condition holds:
+*
+*     - eps <= c[q] <= +eps,                                         (6)
+*
+*  dual feasibility does not depend on a particular value of column q.
+*  In this case the column can be fixed either on its lower bound (if
+*  l[q] > -oo) or on its upper bound (if u[q] < +oo) or at zero (if the
+*  column is unbounded) and then removed from the problem.
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  See the routine npp_fixed_col. Having been recovered the column
+*  is assigned status GLP_NS. However, if actually it is not fixed
+*  (l[q] < u[q]), its status should be changed to GLP_NL, GLP_NU, or
+*  GLP_NF depending on which bound it was fixed on transformation stage.

+*
+*  where l[q] < u[q], the routine npp_implied_value processes its

+*
+*  ALGORITHM
+*
+*  Implied column value s[q] satisfies to the current column bounds if

+*
+*  where floor(s[q]+0.5) is the nearest integer to s[q].
+*
+*  If both condition (2) and (3) are satisfied, the column can be fixed
+*  at the value s[q], or, if it is integral, at floor(s[q]+0.5).
+*  Otherwise, if s[q] violates (2) or (3), the problem has no feasible

+*  NAME
+*
+*  npp_eq_singlet - process row singleton (equality constraint)
+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_eq_singlet(NPP *npp, NPPROW *p);
+*
+*  DESCRIPTION
+*
+*  The routine npp_eq_singlet processes row p, which is equiality
+*  constraint having the only non-zero coefficient:
+*
+*     a[p,q] x[q] = b.                                               (1)
+*
+*  RETURNS
+*
+*  0 - success;
+*
+*  1 - problem has no primal feasible solution;
+*
+*  2 - problem has no integer feasible solution.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  The equality constraint defines implied value of column q:
+*
+*     x[q] = s[q] = b / a[p,q].                                      (2)
+*
+*  If the implied value s[q] satisfies to the column bounds (see the
+*  routine npp_implied_value), the column can be fixed at s[q] and
+*  removed from the problem. In this case row p becomes redundant, so
+*  it can be replaced by equivalent free row and also removed from the
+*  problem.
+*
+*  Note that the routine removes from the problem only row p. Column q
+*  becomes fixed, however, it is kept in the problem.
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  In solution to the original problem row p is assigned status GLP_NS
+*  (active equality constraint), and column q is assigned status GLP_BS
+*  (basic column).
+*
+*  Multiplier for row p can be computed as follows. In the dual system
+*  of the original problem column q corresponds to the following row:
+*
+*     sum a[i,q] pi[i] + lambda[q] = c[q]  ==>
+*      i
+*
+*     sum a[i,q] pi[i] + a[p,q] pi[p] + lambda[q] = c[q].
+*     i!=p
+*
+*  Therefore:
+*
+*               1
+*     pi[p] = ------ (c[q] - lambda[q] - sum a[i,q] pi[i]),          (3)
+*             a[p,q]                     i!=q
+*
+*  where lambda[q] = 0 (since column[q] is basic), and pi[i] for all
+*  i != p are known in solution to the transformed problem.
+*
+*  Value of column q in solution to the original problem is assigned
+*  its implied value s[q].
+*
+*  RECOVERING INTERIOR-POINT SOLUTION
+*
+*  Multiplier for row p is computed with formula (3). Value of column
+*  q is assigned its implied value s[q].
+*
+*  RECOVERING MIP SOLUTION
+*
+*  Value of column q is assigned its implied value s[q]. */

+*

+*
+*  The routine npp_ineq_singlet processes row p, which is inequality
+*  constraint having the only non-zero coefficient:
+*
+*     L[p] <= a[p,q] * x[q] <= U[p],                                 (1)
+*
+*  where L[p] < U[p], L[p] > -oo and/or U[p] < +oo.
+*
+*  RETURNS
+*
+*  0 - current column bounds have not changed;

+*
+*  3 - column has been fixed on its lower or upper bound;
+*
+*  4 - problem has no primal feasible solution.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  Inequality constraint (1) defines implied bounds of column q:
+*
+*             (  L[p] / a[p,q],  if a[p,q] > 0
+*     l'[q] = <                                                      (2)
+*             (  U[p] / a[p,q],  if a[p,q] < 0
+*
+*             (  U[p] / a[p,q],  if a[p,q] > 0
+*     u'[q] = <                                                      (3)
+*             (  L[p] / a[p,q],  if a[p,q] < 0
+*
+*  If these implied bounds do not violate current bounds of column q:
+*
+*     l[q] <= x[q] <= u[q],                                          (4)
+*
+*  they can be used to strengthen the current column bounds:
+*
+*     l[q] := max(l[q], l'[q]),                                      (5)
+*
+*     u[q] := min(u[q], u'[q]).                                      (6)
+*
+*  (See the routines npp_implied_lower and npp_implied_upper.)
+*
+*  Once bounds of row p (1) have been carried over column q, the row
+*  becomes redundant, so it can be replaced by equivalent free row and
+*  removed from the problem.
+*
+*  Note that the routine removes from the problem only row p. Column q,
+*  even it has been fixed, is kept in the problem.
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  Note that the row in the dual system corresponding to column q is
+*  the following:
+*
+*     sum a[i,q] pi[i] + lambda[q] = c[q]  ==>
+*      i
+*                                                                    (7)
+*     sum a[i,q] pi[i] + a[p,q] pi[p] + lambda[q] = c[q],
+*     i!=p
+*
+*  where pi[i] for all i != p are known in solution to the transformed
+*  problem. Row p does not exist in the transformed problem, so it has
+*  zero multiplier there. This allows computing multiplier for column q
+*  in solution to the transformed problem:
+*
+*     lambda~[q] = c[q] - sum a[i,q] pi[i].                          (8)
+*                         i!=p
+*
+*  Let in solution to the transformed problem column q be non-basic
+*  with lower bound active (GLP_NL, lambda~[q] >= 0), and this lower
+*  bound be implied one l'[q]. From the original problem's standpoint
+*  this then means that actually the original column lower bound l[q]
+*  is inactive, and active is that row bound L[p] or U[p] that defines
+*  the implied bound l'[q] (2). In this case in solution to the
+*  original problem column q is assigned status GLP_BS while row p is
+*  assigned status GLP_NL (if a[p,q] > 0) or GLP_NU (if a[p,q] < 0).
+*  Since now column q is basic, its multiplier lambda[q] is zero. This
+*  allows using (7) and (8) to find multiplier for row p in solution to
+*  the original problem:
+*
+*               1
+*     pi[p] = ------ (c[q] - sum a[i,q] pi[i]) = lambda~[q] / a[p,q] (9)
+*             a[p,q]         i!=p
+*
+*  Now let in solution to the transformed problem column q be non-basic
+*  with upper bound active (GLP_NU, lambda~[q] <= 0), and this upper
+*  bound be implied one u'[q]. As in the previous case this then means
+*  that from the original problem's standpoint actually the original
+*  column upper bound u[q] is inactive, and active is that row bound
+*  L[p] or U[p] that defines the implied bound u'[q] (3). In this case
+*  in solution to the original problem column q is assigned status
+*  GLP_BS, row p is assigned status GLP_NU (if a[p,q] > 0) or GLP_NL
+*  (if a[p,q] < 0), and its multiplier is computed with formula (9).
+*
+*  Strengthening bounds of column q according to (5) and (6) may make
+*  it fixed. Thus, if in solution to the transformed problem column q is
+*  non-basic and fixed (GLP_NS), we can suppose that if lambda~[q] > 0,
+*  column q has active lower bound (GLP_NL), and if lambda~[q] < 0,
+*  column q has active upper bound (GLP_NU), reducing this case to two
+*  previous ones. If, however, lambda~[q] is close to zero or
+*  corresponding bound of row p does not exist (this may happen if
+*  lambda~[q] has wrong sign due to round-off errors, in which case it
+*  is expected to be close to zero, since solution is assumed to be dual
+*  feasible), column q can be assigned status GLP_BS (basic), and row p
+*  can be made active on its existing bound. In the latter case row
+*  multiplier pi[p] computed with formula (9) will be also close to
+*  zero, and dual feasibility will be kept.
+*
+*  In all other cases, namely, if in solution to the transformed
+*  problem column q is basic (GLP_BS), or non-basic with original lower
+*  bound l[q] active (GLP_NL), or non-basic with original upper bound
+*  u[q] active (GLP_NU), constraint (1) is inactive. So in solution to
+*  the original problem status of column q remains unchanged, row p is
+*  assigned status GLP_BS, and its multiplier pi[p] is assigned zero
+*  value.
+*
+*  RECOVERING INTERIOR-POINT SOLUTION
+*
+*  First, value of multiplier for column q in solution to the original
+*  problem is computed with formula (8). If lambda~[q] > 0 and column q
+*  has implied lower bound, or if lambda~[q] < 0 and column q has
+*  implied upper bound, this means that from the original problem's
+*  standpoint actually row p has corresponding active bound, in which
+*  case its multiplier pi[p] is computed with formula (9). In other
+*  cases, when the sign of lambda~[q] corresponds to original bound of
+*  column q, or when lambda~[q] =~ 0, value of row multiplier pi[p] is
+*  assigned zero value.
+*
+*  RECOVERING MIP SOLUTION
+*
+*  None needed. */

+*  NAME

+*  npp_implied_slack - process column singleton (implied slack variable)
+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  void npp_implied_slack(NPP *npp, NPPCOL *q);
+*
+*  DESCRIPTION
+*
+*  The routine npp_implied_slack processes column q:
+*
+*     l[q] <= x[q] <= u[q],                                          (1)
+*
+*  where l[q] < u[q], having the only non-zero coefficient in row p,
+*  which is equality constraint:
+*
+*     sum a[p,j] x[j] + a[p,q] x[q] = b.                             (2)
+*     j!=q
+*
+*  PROBLEM TRANSFORMATION
+*
+*  (If x[q] is integral, this transformation must not be used.)
+*
+*  The term a[p,q] x[q] in constraint (2) can be considered as a slack
+*  variable that allows to carry bounds of column q over row p and then
+*  remove column q from the problem.
+*
+*  Constraint (2) can be written as follows:
+*
+*     sum a[p,j] x[j] = b - a[p,q] x[q].                             (3)
+*     j!=q
+*
+*  According to (1) constraint (3) is equivalent to the following
+*  inequality constraint:
+*
+*     L[p] <= sum a[p,j] x[j] <= U[p],                               (4)
+*             j!=q
+*
+*  where
+*
+*            ( b - a[p,q] u[q],  if a[p,q] > 0
+*     L[p] = <                                                       (5)
+*            ( b - a[p,q] l[q],  if a[p,q] < 0
+*
+*            ( b - a[p,q] l[q],  if a[p,q] > 0
+*     U[p] = <                                                       (6)
+*            ( b - a[p,q] u[q],  if a[p,q] < 0
+*
+*  From (2) it follows that:
+*
+*              1
+*     x[q] = ------ (b - sum a[p,j] x[j]).                           (7)
+*            a[p,q]      j!=q
+*
+*  In order to eliminate x[q] from the objective row we substitute it
+*  from (6) to that row:
+*
+*     z = sum c[j] x[j] + c[q] x[q] + c[0] =
+*         j!=q
+*                                 1
+*       = sum c[j] x[j] + c[q] [------ (b - sum a[p,j] x[j])] + c0 =
+*         j!=q                  a[p,q]      j!=q
+*
+*       = sum c~[j] x[j] + c~[0],
+*         j!=q
+*                         a[p,j]                     b
+*     c~[j] = c[j] - c[q] ------,  c~0 = c0 - c[q] ------            (8)
+*                         a[p,q]                   a[p,q]
+*
+*  are values of objective coefficients and constant term, resp., in
+*  the transformed problem.
+*
+*  Note that column q is column singleton, so in the dual system of the
+*  original problem it corresponds to the following row singleton:
+*
+*     a[p,q] pi[p] + lambda[q] = c[q].                               (9)
+*
+*  In the transformed problem row (9) would be the following:
+*
+*     a[p,q] pi~[p] + lambda[q] = c~[q] = 0.                        (10)
+*
+*  Subtracting (10) from (9) we have:
+*
+*     a[p,q] (pi[p] - pi~[p]) = c[q]
+*
+*  that gives the following formula to compute multiplier for row p in
+*  solution to the original problem using its value in solution to the
+*  transformed problem:
+*
+*     pi[p] = pi~[p] + c[q] / a[p,q].                               (11)
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  Status of column q in solution to the original problem is defined
+*  by status of row p in solution to the transformed problem and the
+*  sign of coefficient a[p,q] in the original inequality constraint (2)
+*  as follows:
+*
+*     +-----------------------+---------+--------------------+
+*     |    Status of row p    | Sign of | Status of column q |
+*     | (transformed problem) | a[p,q]  | (original problem) |

+*     |        GLP_NL         |    -    |       GLP_NL       |
+*     |        GLP_NU         |    +    |       GLP_NL       |

+*  Inequality (3) defines implied bounds of variable x[q]:
+*
+*     l'[q] <= x[q] <= u'[q],                                        (7)
+*
+*  where
+*
+*             ( alfa / a[p,q], if a[p,q] > 0
+*     l'[q] = <                                                     (8a)
+*             ( beta / a[p,q], if a[p,q] < 0
+*
+*             ( beta / a[p,q], if a[p,q] > 0
+*     u'[q] = <                                                     (8b)
+*             ( alfa / a[p,q], if a[p,q] < 0
+*
+*  Thus, if l'[q] > l[q] - eps and u'[q] < u[q] + eps, where eps is
+*  an absolute tolerance for column value, column bounds (1) cannot be
+*  active, in which case column q can be replaced by equivalent free
+*  (unbounded) column.
+*
+*  Note that column q is column singleton, so in the dual system of the
+*  original problem it corresponds to the following row singleton:
+*
+*     a[p,q] pi[p] + lambda[q] = c[q],                               (9)
+*
+*  from which it follows that:
+*
+*     pi[p] = (c[q] - lambda[q]) / a[p,q].                          (10)
+*
+*  Let x[q] be implied free (unbounded) variable. Then column q can be
+*  only basic, so its multiplier lambda[q] is equal to zero, and from
+*  (10) we have:
+*
+*     pi[p] = c[q] / a[p,q].                                        (11)
+*
+*  There are possible three cases:
+*
+*  1) pi[p] < -eps, where eps is an absolute tolerance for row
+*     multiplier. In this case, to provide dual feasibility of the
+*     original problem, row p must be active on its lower bound, and
+*     if its lower bound does not exist (L[p] = -oo), the problem has
+*     no dual feasible solution;
+*
+*  2) pi[p] > +eps. In this case row p must be active on its upper
+*     bound, and if its upper bound does not exist (U[p] = +oo), the
+*     problem has no dual feasible solution;
+*
+*  3) -eps <= pi[p] <= +eps. In this case any (either lower or upper)
+*     bound of row p can be active, because this does not affect dual
+*     feasibility.
+*
+*  Thus, in all three cases original inequality constraint (2) can be
+*  replaced by equality constraint, where the right-hand side is either
+*  lower or upper bound of row p, and bounds of column q can be removed
+*  that makes it free (unbounded). (May note that this transformation
+*  can be followed by transformation "Column singleton (implied slack
+*  variable)" performed by the routine npp_implied_slack.)
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  Status of row p in solution to the original problem is determined
+*  by its status in solution to the transformed problem and its bound,
+*  which was choosen to be active:

+*  NAME
+*
+*  npp_eq_doublet - process row doubleton (equality constraint)
+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  NPPCOL *npp_eq_doublet(NPP *npp, NPPROW *p);
+*
+*  DESCRIPTION
+*
+*  The routine npp_eq_doublet processes row p, which is equality
+*  constraint having exactly two non-zero coefficients:
+*
+*     a[p,q] x[q] + a[p,r] x[r] = b.                                 (1)
+*
+*  As the result of processing one of columns q or r is eliminated from
+*  all other rows and, thus, becomes column singleton of type "implied
+*  slack variable". Row p is not changed and along with column q and r
+*  remains in the problem.
+*
+*  RETURNS
+*
+*  The routine npp_eq_doublet returns pointer to the descriptor of that
+*  column q or r which has been eliminated. If, due to some reason, the
+*  elimination was not performed, the routine returns NULL.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  First, we decide which column q or r will be eliminated. Let it be
+*  column q. Consider i-th constraint row, where column q has non-zero
+*  coefficient a[i,q] != 0:
+*
+*     L[i] <= sum a[i,j] x[j] <= U[i].                               (2)
+*              j
+*
+*  In order to eliminate column q from row (2) we subtract from it row
+*  (1) multiplied by gamma[i] = a[i,q] / a[p,q], i.e. we replace in the
+*  transformed problem row (2) by its linear combination with row (1).
+*  This transformation changes only coefficients in columns q and r,
+*  and bounds of row i as follows:
+*
+*     a~[i,q] = a[i,q] - gamma[i] a[p,q] = 0,                        (3)
+*
+*     a~[i,r] = a[i,r] - gamma[i] a[p,r],                            (4)
+*
+*       L~[i] = L[i] - gamma[i] b,                                   (5)
+*
+*       U~[i] = U[i] - gamma[i] b.                                   (6)
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  The transformation of the primal system of the original problem:
+*
+*     L <= A x <= U                                                  (7)
+*
+*  is equivalent to multiplying from the left a transformation matrix F
+*  by components of this primal system, which in the transformed problem
+*  becomes the following:
+*
+*     F L <= F A x <= F U  ==>  L~ <= A~x <= U~.                     (8)
+*
+*  The matrix F has the following structure:
+*
+*         ( 1           -gamma[1]            )
+*         (                                  )
+*         (    1        -gamma[2]            )
+*         (                                  )
+*         (      ...       ...               )
+*         (                                  )
+*     F = (          1  -gamma[p-1]          )                       (9)
+*         (                                  )
+*         (                 1                )
+*         (                                  )
+*         (             -gamma[p+1]  1       )
+*         (                                  )
+*         (                ...          ...  )
+*
+*  where its column containing elements -gamma[i] corresponds to row p
+*  of the primal system.
+*
+*  From (8) it follows that the dual system of the original problem:
+*
+*     A'pi + lambda = c,                                            (10)
+*
+*  in the transformed problem becomes the following:
+*
+*     A'F'inv(F')pi + lambda = c  ==>  (A~)'pi~ + lambda = c,       (11)
+*
+*  where:
+*
+*     pi~ = inv(F')pi                                               (12)
+*
+*  is the vector of row multipliers in the transformed problem. Thus:
+*
+*     pi = F'pi~.                                                   (13)
+*
+*  Therefore, as it follows from (13), value of multiplier for row p in
+*  solution to the original problem can be computed as follows:
+*
+*     pi[p] = pi~[p] - sum gamma[i] pi~[i],                         (14)
+*                       i
+*
+*  where pi~[i] = pi[i] is multiplier for row i (i != p).
+*
+*  Note that the statuses of all rows and columns are not changed.
+*
+*  RECOVERING INTERIOR-POINT SOLUTION
+*
+*  Multiplier for row p in solution to the original problem is computed
+*  with formula (14).

+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_forcing_row(NPP *npp, NPPROW *p, int at);
+*
+*  DESCRIPTION
+*
+*  The routine npp_forcing row processes row p of general format:
+*
+*     L[p] <= sum a[p,j] x[j] <= U[p],                               (1)
+*              j
+*
+*     l[j] <= x[j] <= u[j],                                          (2)
+*
+*  where L[p] <= U[p] and l[j] < u[j] for all a[p,j] != 0. It is also
+*  assumed that:
+*
+*  1) if at = 0 then |L[p] - U'[p]| <= eps, where U'[p] is implied
+*     row upper bound (see below), eps is an absolute tolerance for row
+*     value;
+*
+*  2) if at = 1 then |U[p] - L'[p]| <= eps, where L'[p] is implied
+*     row lower bound (see below).
+*
+*  RETURNS
+*
+*  0 - success;
+*
+*  1 - cannot fix columns due to too small constraint coefficients.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  Implied lower and upper bounds of row (1) are determined by bounds
+*  of corresponding columns (variables) as follows:
+*
+*     L'[p] = inf sum a[p,j] x[j] =
+*                  j
+*                                                                    (3)
+*           =  sum  a[p,j] l[j] +  sum  a[p,j] u[j],
+*            j in Jp             j in Jn
+*
+*     U'[p] = sup sum a[p,j] x[j] =
+*                                                                    (4)
+*           =  sum  a[p,j] u[j] +  sum  a[p,j] l[j],
+*            j in Jp             j in Jn
+*
+*     Jp = {j: a[p,j] > 0},  Jn = {j: a[p,j] < 0}.                   (5)
+*
+*  If L[p] =~ U'[p] (at = 0), solution can be primal feasible only when
+*  all variables take their boundary values as defined by (4):
+*
+*            ( u[j], if j in Jp
+*     x[j] = <                                                       (6)
+*            ( l[j], if j in Jn
+*
+*  Similarly, if U[p] =~ L'[p] (at = 1), solution can be primal feasible
+*  only when all variables take their boundary values as defined by (3):
+*
+*            ( l[j], if j in Jp
+*     x[j] = <                                                       (7)
+*            ( u[j], if j in Jn
+*
+*  Condition (6) or (7) allows fixing all columns (variables x[j])
+*  in row (1) on their bounds and then removing them from the problem
+*  (see the routine npp_fixed_col). Due to this row p becomes redundant,
+*  so it can be replaced by equivalent free (unbounded) row and also
+*  removed from the problem (see the routine npp_free_row).
+*
+*  1. To apply this transformation row (1) should not have coefficients
+*     whose magnitude is too small, i.e. all a[p,j] should satisfy to
+*     the following condition:
+*
+*        |a[p,j]| >= eps * max(1, |a[p,k]|),                         (8)
+*                           k
+*     where eps is a relative tolerance for constraint coefficients.
+*     Otherwise, fixing columns may be numerically unreliable and may
+*     lead to wrong solution.
+*
+*  2. The routine fixes columns and remove bounds of row p, however,
+*     it does not remove the row and columns from the problem.
+*
+*  RECOVERING BASIC SOLUTION
+*
+*  In the transformed problem row p being inactive constraint is
+*  assigned status GLP_BS (as the result of transformation of free
+*  row), and all columns in this row are assigned status GLP_NS (as the
+*  result of transformation of fixed columns).
+*
+*  Note that in the dual system of the transformed (as well as original)
+*  problem every column j in row p corresponds to the following row:
+*
+*     sum  a[i,j] pi[i] + a[p,j] pi[p] + lambda[j] = c[j],           (9)
+*     i!=p
+*
+*  from which it follows that:
+*
+*     lambda[j] = c[j] - sum a[i,j] pi[i] - a[p,j] pi[p].           (10)
+*                        i!=p
+*
+*  In the transformed problem values of all multipliers pi[i] are known
+*  (including pi[i], whose value is zero, since row p is inactive).
+*  Thus, using formula (10) it is possible to compute values of
+*  multipliers lambda[j] for all columns in row p.
+*
+*  Note also that in the original problem all columns in row p are
+*  bounded, not fixed. So status GLP_NS assigned to every such column
+*  must be changed to GLP_NL or GLP_NU depending on which bound the
+*  corresponding column has been fixed. This status change may lead to
+*  dual feasibility violation for solution of the original problem,
+*  because now column multipliers must satisfy to the following
+*  condition:
+*
+*               ( >= 0, if status of column j is GLP_NL,
+*     lambda[j] <                                                   (11)
+*               ( <= 0, if status of column j is GLP_NU.
+*
+*  If this condition holds, solution to the original problem is the
+*  same as to the transformed problem. Otherwise, we have to perform
+*  one degenerate pivoting step of the primal simplex method to obtain
+*  dual feasible (hence, optimal) solution to the original problem as
+*  follows. If, on problem transformation, row p was made active on its
+*  lower bound (case at = 0), we change its status to GLP_NL (or GLP_NS)
+*  and start increasing its multiplier pi[p]. Otherwise, if row p was
+*  made active on its upper bound (case at = 1), we change its status
+*  to GLP_NU (or GLP_NS) and start decreasing pi[p]. From (10) it
+*  follows that:
+*
+*     delta lambda[j] = - a[p,j] * delta pi[p] = - a[p,j] pi[p].    (12)
+*
+*  Simple analysis of formulae (3)-(5) shows that changing pi[p] in the
+*  specified direction causes increasing lambda[j] for every column j
+*  assigned status GLP_NL (delta lambda[j] > 0) and decreasing lambda[j]
+*  for every column j assigned status GLP_NU (delta lambda[j] < 0). It
+*  is understood that once the last lambda[q], which violates condition
+*  (11), has reached zero, multipliers lambda[j] for all columns get
+*  valid signs. Such column q can be determined as follows. Let d[j] be
+*  initial value of lambda[j] (i.e. reduced cost of column j) in the
+*  transformed problem computed with formula (10) when pi[p] = 0. Then
+*  lambda[j] = d[j] + delta lambda[j], and from (12) it follows that
+*  lambda[j] becomes zero if:
+*
+*     delta lambda[j] = - a[p,j] pi[p] = - d[j]  ==>
+*                                                                   (13)
+*     pi[p] = d[j] / a[p,j].
+*
+*  Therefore, the last column q, for which lambda[q] becomes zero, can
+*  be determined from the following condition:
+*
+*     |d[q] / a[p,q]| = max  |pi[p]| = max  |d[j] / a[p,j]|,        (14)
+*                      j in D         j in D
+*
+*  where D is a set of columns j whose, reduced costs d[j] have invalid
+*  signs, i.e. violate condition (11). (Thus, if D is empty, solution
+*  to the original problem is the same as solution to the transformed
+*  problem, and no correction is needed as was noticed above.) In
+*  solution to the original problem column q is assigned status GLP_BS,
+*  since it replaces column of auxiliary variable of row p (becoming
+*  active) in the basis, and multiplier for row p is assigned its new
+*  value, which is pi[p] = d[q] / a[p,q]. Note that due to primal
+*  degeneracy values of all columns having non-zero coefficients in row
+*  p remain unchanged.
+*
+*  RECOVERING INTERIOR-POINT SOLUTION
+*
+*  Value of multiplier pi[p] in solution to the original problem is
+*  corrected in the same way as for basic solution. Values of all
+*  columns having non-zero coefficients in row p remain unchanged.
+*
+*  RECOVERING MIP SOLUTION
+*
+*  None needed. */

+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_analyze_row(NPP *npp, NPPROW *p);
+*
+*  DESCRIPTION
+*
+*  The routine npp_analyze_row performs analysis of row p of general
+*  format:
+*
+*     L[p] <= sum a[p,j] x[j] <= U[p],                               (1)
+*              j
+*
+*     l[j] <= x[j] <= u[j],                                          (2)
+*
+*  where L[p] <= U[p] and l[j] <= u[j] for all a[p,j] != 0.
+*
+*  RETURNS
+*
+*  0x?0 - row lower bound does not exist or is redundant;
+*
+*  0x?1 - row lower bound can be active;
+*
+*  0x?2 - row lower bound is a forcing bound;
+*
+*  0x0? - row upper bound does not exist or is redundant;
+*
+*  0x1? - row upper bound can be active;
+*
+*  0x2? - row upper bound is a forcing bound;
+*
+*  0x33 - row bounds are inconsistent with column bounds.
+*
+*  ALGORITHM
+*
+*  Analysis of row (1) is based on analysis of its implied lower and
+*  upper bounds, which are determined by bounds of corresponding columns
+*  (variables) as follows:
+*
+*     L'[p] = inf sum a[p,j] x[j] =
+*                  j
+*                                                                    (3)
+*           =  sum  a[p,j] l[j] +  sum  a[p,j] u[j],
+*            j in Jp             j in Jn
+*
+*     U'[p] = sup sum a[p,j] x[j] =
+*                                                                    (4)
+*           =  sum  a[p,j] u[j] +  sum  a[p,j] l[j],
+*            j in Jp             j in Jn
+*
+*     Jp = {j: a[p,j] > 0},  Jn = {j: a[p,j] < 0}.                   (5)
+*
+*  (Note that bounds of all columns in row p are assumed to be correct,
+*  so L'[p] <= U'[p].)
+*
+*  Analysis of row lower bound L[p] includes the following cases:
+*
+*  1) if L[p] > U'[p] + eps, where eps is an absolute tolerance for row
+*     value, row lower bound L[p] and implied row upper bound U'[p] are
+*     inconsistent, ergo, the problem has no primal feasible solution;
+*
+*  2) if U'[p] - eps <= L[p] <= U'[p] + eps, i.e. if L[p] =~ U'[p],
+*     the row is a forcing row on its lower bound (see description of
+*     the routine npp_forcing_row);
+*
+*  3) if L[p] > L'[p] + eps, row lower bound L[p] can be active (this
+*     conclusion does not account other rows in the problem);
+*
+*  4) if L[p] <= L'[p] + eps, row lower bound L[p] cannot be active, so
+*     it is redundant and can be removed (replaced by -oo).
+*
+*  Analysis of row upper bound U[p] is performed in a similar way and
+*  includes the following cases:
+*
+*  1) if U[p] < L'[p] - eps, row upper bound U[p] and implied row lower
+*     bound L'[p] are inconsistent, ergo the problem has no primal
+*     feasible solution;
+*
+*  2) if L'[p] - eps <= U[p] <= L'[p] + eps, i.e. if U[p] =~ L'[p],
+*     the row is a forcing row on its upper bound (see description of
+*     the routine npp_forcing_row);
+*
+*  3) if U[p] < U'[p] - eps, row upper bound U[p] can be active (this
+*     conclusion does not account other rows in the problem);
+*
+*  4) if U[p] >= U'[p] - eps, row upper bound U[p] cannot be active, so
+*     it is redundant and can be removed (replaced by +oo). */

+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  void npp_implied_bounds(NPP *npp, NPPROW *p);
+*
+*  DESCRIPTION
+*
+*  The routine npp_implied_bounds inspects general row (constraint) p:
+*
+*     L[p] <= sum a[p,j] x[j] <= U[p],                               (1)
+*
+*     l[j] <= x[j] <= u[j],                                          (2)
+*
+*  where L[p] <= U[p] and l[j] <= u[j] for all a[p,j] != 0, to compute
+*  implied bounds of columns (variables x[j]) in this row.
+*
+*  The routine stores implied column bounds l'[j] and u'[j] in column
+*  descriptors (NPPCOL); it does not change current column bounds l[j]
+*  and u[j]. (Implied column bounds can be then used to strengthen the
+*  current column bounds; see the routines npp_implied_lower and
+*  npp_implied_upper).
+*
+*  ALGORITHM
+*
+*  Current column bounds (2) define implied lower and upper bounds of
+*  row (1) as follows:
+*
+*     L'[p] = inf sum a[p,j] x[j] =
+*                  j
+*                                                                    (3)
+*           =  sum  a[p,j] l[j] +  sum  a[p,j] u[j],
+*            j in Jp             j in Jn
+*
+*     U'[p] = sup sum a[p,j] x[j] =
+*                                                                    (4)
+*           =  sum  a[p,j] u[j] +  sum  a[p,j] l[j],
+*            j in Jp             j in Jn
+*
+*     Jp = {j: a[p,j] > 0},  Jn = {j: a[p,j] < 0}.                   (5)
+*
+*  (Note that bounds of all columns in row p are assumed to be correct,
+*  so L'[p] <= U'[p].)
+*
+*  If L[p] > L'[p] and/or U[p] < U'[p], the lower and/or upper bound of
+*  row (1) can be active, in which case such row defines implied bounds
+*  of its variables.
+*
+*  Let x[k] be some variable having in row (1) coefficient a[p,k] != 0.
+*  Consider a case when row lower bound can be active (L[p] > L'[p]):
+*
+*     sum a[p,j] x[j] >= L[p]  ==>
+*      j
+*
+*     sum a[p,j] x[j] + a[p,k] x[k] >= L[p]  ==>
+*     j!=k
+*                                                                    (6)
+*     a[p,k] x[k] >= L[p] - sum a[p,j] x[j]  ==>
+*                           j!=k
+*
+*     a[p,k] x[k] >= L[p,k],
+*
+*  where
+*
+*     L[p,k] = inf(L[p] - sum a[p,j] x[j]) =
+*                         j!=k
+*
+*            = L[p] - sup sum a[p,j] x[j] =                          (7)
+*                         j!=k
+*
+*            = L[p] - sum a[p,j] u[j] - sum a[p,j] l[j].
+*                    j in Jp\{k}       j in Jn\{k}
+*
+*  Thus:
+*
+*     x[k] >= l'[k] = L[p,k] / a[p,k],  if a[p,k] > 0,               (8)
+*
+*     x[k] <= u'[k] = L[p,k] / a[p,k],  if a[p,k] < 0.               (9)
+*
+*  where l'[k] and u'[k] are implied lower and upper bounds of variable
+*  x[k], resp.
+*
+*  Now consider a similar case when row upper bound can be active
+*  (U[p] < U'[p]):
+*
+*     sum a[p,j] x[j] <= U[p]  ==>
+*      j
+*
+*     sum a[p,j] x[j] + a[p,k] x[k] <= U[p]  ==>
+*     j!=k
+*                                                                   (10)
+*     a[p,k] x[k] <= U[p] - sum a[p,j] x[j]  ==>
+*                           j!=k
+*
+*     a[p,k] x[k] <= U[p,k],
+*
+*  where:
+*
+*     U[p,k] = sup(U[p] - sum a[p,j] x[j]) =
+*                         j!=k
+*
+*            = U[p] - inf sum a[p,j] x[j] =                         (11)
+*                         j!=k
+*
+*            = U[p] - sum a[p,j] l[j] - sum a[p,j] u[j].
+*                    j in Jp\{k}       j in Jn\{k}
+*
+*  Thus:
+*
+*     x[k] <= u'[k] = U[p,k] / a[p,k],  if a[p,k] > 0,              (12)
+*
+*     x[k] >= l'[k] = U[p,k] / a[p,k],  if a[p,k] < 0.              (13)
+*
+*  Note that in formulae (8), (9), (12), and (13) coefficient a[p,k]
+*  must not be too small in magnitude relatively to other non-zero
+*  coefficients in row (1), i.e. the following condition must hold:
+*
+*     |a[p,k]| >= eps * max(1, |a[p,j]|),                           (14)
+*                        j
+*
+*  where eps is a relative tolerance for constraint coefficients.
+*  Otherwise the implied column bounds can be numerical inreliable. For
+*  example, using formula (8) for the following inequality constraint:
+*
+*     1e-12 x1 - x2 - x3 >= 0,
+*
+*  where x1 >= -1, x2, x3, >= 0, may lead to numerically unreliable
+*  conclusion that x1 >= 0.
+*
+*  Using formulae (8), (9), (12), and (13) to compute implied bounds
+*  for one variable requires |J| operations, where J = {j: a[p,j] != 0},
+*  because this needs computing L[p,k] and U[p,k]. Thus, computing
+*  implied bounds for all variables in row (1) would require |J|^2
+*  operations, that is not a good technique. However, the total number
+*  of operations can be reduced to |J| as follows.
+*
+*  Let a[p,k] > 0. Then from (7) and (11) we have:
+*
+*     L[p,k] = L[p] - (U'[p] - a[p,k] u[k]) =
+*
+*            = L[p] - U'[p] + a[p,k] u[k],
+*
+*     U[p,k] = U[p] - (L'[p] - a[p,k] l[k]) =
+*
+*            = U[p] - L'[p] + a[p,k] l[k],
+*
+*  where L'[p] and U'[p] are implied row lower and upper bounds defined
+*  by formulae (3) and (4). Substituting these expressions into (8) and
+*  (12) gives:
+*
+*     l'[k] = L[p,k] / a[p,k] = u[k] + (L[p] - U'[p]) / a[p,k],     (15)
+*
+*     u'[k] = U[p,k] / a[p,k] = l[k] + (U[p] - L'[p]) / a[p,k].     (16)
+*
+*  Similarly, if a[p,k] < 0, according to (7) and (11) we have:
+*
+*     L[p,k] = L[p] - (U'[p] - a[p,k] l[k]) =
+*
+*            = L[p] - U'[p] + a[p,k] l[k],
+*
+*     U[p,k] = U[p] - (L'[p] - a[p,k] u[k]) =
+*
+*            = U[p] - L'[p] + a[p,k] u[k],
+*
+*  and substituting these expressions into (8) and (12) gives:
+*
+*     l'[k] = U[p,k] / a[p,k] = u[k] + (U[p] - L'[p]) / a[p,k],     (17)
+*
+*     u'[k] = L[p,k] / a[p,k] = l[k] + (L[p] - U'[p]) / a[p,k].     (18)
+*
+*  Note that formulae (15)-(18) can be used only if L'[p] and U'[p]
+*  exist. However, if for some variable x[j] it happens that l[j] = -oo
+*  and/or u[j] = +oo, values of L'[p] (if a[p,j] > 0) and/or U'[p] (if
+*  a[p,j] < 0) are undefined. Consider, therefore, the most general
+*  situation, when some column bounds (2) may not exist.
+*
+*  Let:
+*
+*     J' = {j : (a[p,j] > 0 and l[j] = -oo) or
+*                                                                   (19)
+*               (a[p,j] < 0 and u[j] = +oo)}.
+*
+*  Then (assuming that row upper bound U[p] can be active) the following
+*  three cases are possible:
+*
+*  1) |J'| = 0. In this case L'[p] exists, thus, for all variables x[j]
+*     in row (1) we can use formulae (16) and (17);
+*
+*  2) J' = {k}. In this case L'[p] = -oo, however, U[p,k] (11) exists,
+*     so for variable x[k] we can use formulae (12) and (13). Note that
+*     for all other variables x[j] (j != k) l'[j] = -oo (if a[p,j] < 0)
+*     or u'[j] = +oo (if a[p,j] > 0);
+*
+*  3) |J'| > 1. In this case for all variables x[j] in row [1] we have
+*     l'[j] = -oo (if a[p,j] < 0) or u'[j] = +oo (if a[p,j] > 0).
+*
+*  Similarly, let:
+*
+*     J'' = {j : (a[p,j] > 0 and u[j] = +oo) or
+*                                                                   (20)
+*                (a[p,j] < 0 and l[j] = -oo)}.
+*
+*  Then (assuming that row lower bound L[p] can be active) the following
+*  three cases are possible:
+*
+*  1) |J''| = 0. In this case U'[p] exists, thus, for all variables x[j]
+*     in row (1) we can use formulae (15) and (18);
+*
+*  2) J'' = {k}. In this case U'[p] = +oo, however, L[p,k] (7) exists,
+*     so for variable x[k] we can use formulae (8) and (9). Note that
+*     for all other variables x[j] (j != k) l'[j] = -oo (if a[p,j] > 0)
+*     or u'[j] = +oo (if a[p,j] < 0);
+*
+*  3) |J''| > 1. In this case for all variables x[j] in row (1) we have
+*     l'[j] = -oo (if a[p,j] > 0) or u'[j] = +oo (if a[p,j] < 0). */

+*  npp_binarize_prob - binarize MIP problem
+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_binarize_prob(NPP *npp);
+*
+*  DESCRIPTION
+*
+*  The routine npp_binarize_prob replaces in the original MIP problem
+*  every integer variable:
+*
+*     l[q] <= x[q] <= u[q],                                          (1)
+*
+*  where l[q] < u[q], by an equivalent sum of binary variables.
+*
+*  RETURNS
+*
+*  The routine returns the number of integer variables for which the
+*  transformation failed, because u[q] - l[q] > d_max.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  If variable x[q] has non-zero lower bound, it is first processed
+*  with the routine npp_lbnd_col. Thus, we can assume that:
+*
+*     0 <= x[q] <= u[q].                                             (2)
+*
+*  If u[q] = 1, variable x[q] is already binary, so further processing
+*  is not needed. Let, therefore, that 2 <= u[q] <= d_max, and n be a
+*  smallest integer such that u[q] <= 2^n - 1 (n >= 2, since u[q] >= 2).
+*  Then variable x[q] can be replaced by the following sum:
+*
+*            n-1
+*     x[q] = sum 2^k x[k],                                           (3)
+*            k=0
+*
+*  where x[k] are binary columns (variables). If u[q] < 2^n - 1, the
+*  following additional inequality constraint must be also included in
+*  the transformed problem:
+*
+*     n-1
+*     sum 2^k x[k] <= u[q].                                          (4)
+*     k=0
+*
+*  Note: Assuming that in the transformed problem x[q] becomes binary
+*  variable x[0], this transformation causes new n-1 binary variables
+*  to appear.
+*
+*  Substituting x[q] from (3) to the objective row gives:
+*
+*     z = sum c[j] x[j] + c[0] =
+*          j
+*
+*       = sum c[j] x[j] + c[q] x[q] + c[0] =
+*         j!=q
+*                              n-1
+*       = sum c[j] x[j] + c[q] sum 2^k x[k] + c[0] =
+*         j!=q                 k=0
+*                         n-1
+*       = sum c[j] x[j] + sum c[k] x[k] + c[0],
+*         j!=q            k=0
+*
+*  where:
+*
+*     c[k] = 2^k c[q],  k = 0, ..., n-1.                             (5)
+*
+*  And substituting x[q] from (3) to i-th constraint row i gives:
+*
+*     L[i] <= sum a[i,j] x[j] <= U[i]  ==>
+*              j
+*
+*     L[i] <= sum a[i,j] x[j] + a[i,q] x[q] <= U[i]  ==>
+*             j!=q
+*                                      n-1
+*     L[i] <= sum a[i,j] x[j] + a[i,q] sum 2^k x[k] <= U[i]  ==>
+*             j!=q                     k=0
+*                               n-1
+*     L[i] <= sum a[i,j] x[j] + sum a[i,k] x[k] <= U[i],
+*             j!=q              k=0
+*
+*  where:
+*
+*     a[i,k] = 2^k a[i,q],  k = 0, ..., n-1.                         (6)

+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_hidden_packing(NPP *npp, NPPROW *row);
+*
+*  DESCRIPTION
+*
+*  The routine npp_hidden_packing processes specified inequality
+*  constraint, which includes only binary variables, and the number of
+*  the variables is not less than two. If the original inequality is
+*  equivalent to a packing inequality, the routine replaces it by this
+*  equivalent inequality. If the original constraint is double-sided
+*  inequality, it is replaced by a pair of single-sided inequalities,
+*  if necessary.
+*
+*  RETURNS
+*
+*  If the original inequality constraint was replaced by equivalent
+*  packing inequality, the routine npp_hidden_packing returns non-zero.
+*  Otherwise, it returns zero.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  Consider an inequality constraint:
+*
+*     sum  a[j] x[j] <= b,                                           (1)
+*    j in J
+*
+*  where all variables x[j] are binary, and |J| >= 2. (In case of '>='
+*  inequality it can be transformed to '<=' format by multiplying both
+*  its sides by -1.)
+*
+*  Let Jp = {j: a[j] > 0}, Jn = {j: a[j] < 0}. Performing substitution
+*  x[j] = 1 - x~[j] for all j in Jn, we have:
+*
+*     sum   a[j] x[j] <= b  ==>
+*    j in J
+*
+*     sum   a[j] x[j] + sum   a[j] x[j] <= b  ==>
+*    j in Jp           j in Jn
+*
+*     sum   a[j] x[j] + sum   a[j] (1 - x~[j]) <= b  ==>
+*    j in Jp           j in Jn
+*
+*     sum   a[j] x[j] - sum   a[j] x~[j] <= b - sum   a[j].
+*    j in Jp           j in Jn                 j in Jn
+*
+*  Thus, meaning the transformation above, we can assume that in
+*  inequality (1) all coefficients a[j] are positive. Moreover, we can
+*  assume that a[j] <= b. In fact, let a[j] > b; then the following
+*  three cases are possible:
+*
+*  1) b < 0. In this case inequality (1) is infeasible, so the problem
+*     has no feasible solution (see the routine npp_analyze_row);
+*
+*  2) b = 0. In this case inequality (1) is a forcing inequality on its
+*     upper bound (see the routine npp_forcing row), from which it
+*     follows that all variables x[j] should be fixed at zero;
+*
+*  3) b > 0. In this case inequality (1) defines an implied zero upper
+*     bound for variable x[j] (see the routine npp_implied_bounds), from
+*     which it follows that x[j] should be fixed at zero.
+*
+*  It is assumed that all three cases listed above have been recognized
+*  by the routine npp_process_prob, which performs basic MIP processing
+*  prior to a call the routine npp_hidden_packing. So, if one of these
+*  cases occurs, we should just skip processing such constraint.
+*
+*  Thus, let 0 < a[j] <= b. Then it is obvious that constraint (1) is
+*  equivalent to packing inquality only if:
+*
+*     a[j] + a[k] > b + eps                                          (2)
+*
+*  for all j, k in J, j != k, where eps is an absolute tolerance for
+*  row (linear form) value. Checking the condition (2) for all j and k,
+*  j != k, requires time O(|J|^2). However, this time can be reduced to
+*  O(|J|), if use minimal a[j] and a[k], in which case it is sufficient
+*  to check the condition (2) only once.
+*
+*  Once the original inequality (1) is replaced by equivalent packing
+*  inequality, we need to perform back substitution x~[j] = 1 - x[j] for
+*  all j in Jn (see above).
+*
+*  RECOVERING SOLUTION

+*     NPPCOL *var[], char set[]);
+*
+*  DESCRIPTION
+*
+*  The routine npp_implied_packing processes specified row (constraint)
+*  of general format:
+*
+*     L <= sum a[j] x[j] <= U.                                       (1)
+*           j
+*
+*  If which = 0, only lower bound L, which must exist, is considered,
+*  while upper bound U is ignored. Similarly, if which = 1, only upper
+*  bound U, which must exist, is considered, while lower bound L is
+*  ignored. Thus, if the specified row is a double-sided inequality or
+*  equality constraint, this routine should be called twice for both
+*  lower and upper bounds.
+*
+*  The routine npp_implied_packing attempts to find a non-trivial (i.e.
+*  having not less than two binary variables) packing inequality:
+*
+*     sum   x[j] - sum   x[j] <= 1 - |Jn|,                           (2)
+*    j in Jp      j in Jn
+*
+*  which is relaxation of the constraint (1) in the sense that any
+*  solution satisfying to that constraint also satisfies to the packing
+*  inequality (2). If such relaxation exists, the routine stores
+*  pointers to descriptors of corresponding binary variables and their
+*  flags, resp., to locations var[1], var[2], ..., var[len] and set[1],
+*  set[2], ..., set[len], where set[j] = 0 means that j in Jp and
+*  set[j] = 1 means that j in Jn.
+*
+*  RETURNS
+*
+*  The routine npp_implied_packing returns len, which is the total
+*  number of binary variables in the packing inequality found, len >= 2.
+*  However, if the relaxation does not exist, the routine returns zero.
+*
+*  ALGORITHM
+*
+*  If which = 0, the constraint coefficients (1) are multiplied by -1
+*  and b is assigned -L; if which = 1, the constraint coefficients (1)
+*  are not changed and b is assigned +U. In both cases the specified
+*  constraint gets the following format:
+*
+*     sum a[j] x[j] <= b.                                            (3)
+*      j
+*
+*  (Note that (3) is a relaxation of (1), because one of bounds L or U
+*  is ignored.)
+*
+*  Let J be set of binary variables, Kp be set of non-binary (integer
+*  or continuous) variables with a[j] > 0, and Kn be set of non-binary
+*  variables with a[j] < 0. Then the inequality (3) can be written as
+*  follows:
+*
+*     sum  a[j] x[j] <= b - sum   a[j] x[j] - sum   a[j] x[j].       (4)
+*    j in J                j in Kp           j in Kn
+*
+*  To get rid of non-binary variables we can replace the inequality (4)
+*  by the following relaxed inequality:
+*
+*     sum  a[j] x[j] <= b~,                                          (5)
+*    j in J
+*
+*  where:
+*
+*     b~ = sup(b - sum   a[j] x[j] - sum   a[j] x[j]) =
+*                 j in Kp           j in Kn
+*
+*        = b - inf sum   a[j] x[j] - inf sum   a[j] x[j] =           (6)
+*                 j in Kp               j in Kn
+*
+*        = b - sum   a[j] l[j] - sum   a[j] u[j].
+*             j in Kp           j in Kn
+*
+*  Note that if lower bound l[j] (if j in Kp) or upper bound u[j]
+*  (if j in Kn) of some non-binary variable x[j] does not exist, then
+*  formally b = +oo, in which case further analysis is not performed.
+*
+*  Let Bp = {j in J: a[j] > 0}, Bn = {j in J: a[j] < 0}. To make all
+*  the inequality coefficients in (5) positive, we replace all x[j] in
+*  Bn by their complementaries, substituting x[j] = 1 - x~[j] for all
+*  j in Bn, that gives:
+*
+*     sum   a[j] x[j] - sum   a[j] x~[j] <= b~ - sum   a[j].         (7)
+*    j in Bp           j in Bn                  j in Bn
+*
+*  This inequality is a relaxation of the original constraint (1), and
+*  it is a binary knapsack inequality. Writing it in the standard format
+*  we have:
+*
+*     sum  alfa[j] z[j] <= beta,                                     (8)
+*    j in J
+*
+*  where:
+*               ( + a[j],   if j in Bp,
+*     alfa[j] = <                                                    (9)
+*               ( - a[j],   if j in Bn,
+*
+*               ( x[j],     if j in Bp,
+*        z[j] = <                                                   (10)
+*               ( 1 - x[j], if j in Bn,
+*
+*        beta = b~ - sum   a[j].                                    (11)
+*                   j in Bn
+*
+*  In the inequality (8) all coefficients are positive, therefore, the
+*  packing relaxation to be found for this inequality is the following:
+*
+*     sum  z[j] <= 1.                                               (12)
+*    j in P
+*
+*  It is obvious that set P within J, which we would like to find, must
+*  satisfy to the following condition:
+*
+*     alfa[j] + alfa[k] > beta + eps  for all j, k in P, j != k,    (13)
+*
+*  where eps is an absolute tolerance for value of the linear form.
+*  Thus, it is natural to take P = {j: alpha[j] > (beta + eps) / 2}.
+*  Moreover, if in the equality (8) there exist coefficients alfa[k],
+*  for which alfa[k] <= (beta + eps) / 2, but which, nevertheless,
+*  satisfies to the condition (13) for all j in P, *one* corresponding
+*  variable z[k] (having, for example, maximal coefficient alfa[k]) can
+*  be included in set P, that allows increasing the number of binary
+*  variables in (12) by one.
+*
+*  Once the set P has been built, for the inequality (12) we need to
+*  perform back substitution according to (10) in order to express it
+*  through the original binary variables. As the result of such back
+*  substitution the relaxed packing inequality get its final format (2),
+*  where Jp = J intersect Bp, and Jn = J intersect Bn. */

+*
+*  If the specified row (constraint) is covering inequality (see below),

+*
+*  COVERING INEQUALITIES
+*
+*  In canonical format the covering inequality is the following:
+*
+*     sum  x[j] >= 1,                                                (1)
+*    j in J
+*
+*  where all variables x[j] are binary. This inequality expresses the
+*  condition that in any integer feasible solution variables in set J
+*  cannot be all equal to zero at the same time, i.e. at least one
+*  variable must take non-zero (unity) value. W.l.o.g. it is assumed
+*  that |J| >= 2, because if J is empty, the inequality (1) is
+*  infeasible, and if |J| = 1, the inequality (1) is a forcing row.
+*
+*  In general case the covering inequality may include original
+*  variables x[j] as well as their complements x~[j]:
+*
+*     sum   x[j] + sum   x~[j] >= 1,                                 (2)
+*    j in Jp      j in Jn
+*

+*
+*  (May note that the inequality (3) cuts off infeasible solutions,

+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_hidden_covering(NPP *npp, NPPROW *row);
+*
+*  DESCRIPTION
+*
+*  The routine npp_hidden_covering processes specified inequality
+*  constraint, which includes only binary variables, and the number of
+*  the variables is not less than three. If the original inequality is
+*  equivalent to a covering inequality (see below), the routine
+*  replaces it by the equivalent inequality. If the original constraint
+*  is double-sided inequality, it is replaced by a pair of single-sided
+*  inequalities, if necessary.
+*
+*  RETURNS
+*
+*  If the original inequality constraint was replaced by equivalent
+*  covering inequality, the routine npp_hidden_covering returns
+*  non-zero. Otherwise, it returns zero.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  Consider an inequality constraint:
+*
+*     sum  a[j] x[j] >= b,                                           (1)
+*    j in J
+*
+*  where all variables x[j] are binary, and |J| >= 3. (In case of '<='
+*  inequality it can be transformed to '>=' format by multiplying both
+*  its sides by -1.)
+*
+*  Let Jp = {j: a[j] > 0}, Jn = {j: a[j] < 0}. Performing substitution
+*  x[j] = 1 - x~[j] for all j in Jn, we have:
+*
+*     sum   a[j] x[j] >= b  ==>
+*    j in J
+*
+*     sum   a[j] x[j] + sum   a[j] x[j] >= b  ==>
+*    j in Jp           j in Jn
+*
+*     sum   a[j] x[j] + sum   a[j] (1 - x~[j]) >= b  ==>
+*    j in Jp           j in Jn
+*
+*     sum  m   a[j] x[j] - sum   a[j] x~[j] >= b - sum   a[j].
+*    j in Jp              j in Jn                 j in Jn
+*
+*  Thus, meaning the transformation above, we can assume that in
+*  inequality (1) all coefficients a[j] are positive. Moreover, we can
+*  assume that b > 0, because otherwise the inequality (1) would be
+*  redundant (see the routine npp_analyze_row). It is then obvious that
+*  constraint (1) is equivalent to covering inequality only if:
+*
+*     a[j] >= b,                                                     (2)
+*
+*  for all j in J.
+*
+*  Once the original inequality (1) is replaced by equivalent covering
+*  inequality, we need to perform back substitution x~[j] = 1 - x[j] for
+*  all j in Jn (see above).

+*
+*  PARTITIONING EQUALITIES
+*
+*  In canonical format the partitioning equality is the following:

+*    j in J
+*
+*  where all variables x[j] are binary. This equality expresses the
+*  condition that in any integer feasible solution exactly one variable
+*  in set J must take non-zero (unity) value while other variables must
+*  be equal to zero. W.l.o.g. it is assumed that |J| >= 2, because if
+*  J is empty, the inequality (1) is infeasible, and if |J| = 1, the
+*  inequality (1) is a fixing row.

+*  NAME
+*
+*  npp_reduce_ineq_coef - reduce inequality constraint coefficients
+*
+*  SYNOPSIS
+*
+*  #include "glpnpp.h"
+*  int npp_reduce_ineq_coef(NPP *npp, NPPROW *row);
+*
+*  DESCRIPTION
+*
+*  The routine npp_reduce_ineq_coef processes specified inequality
+*  constraint attempting to replace it by an equivalent constraint,
+*  where magnitude of coefficients at binary variables is smaller than
+*  in the original constraint. If the inequality is double-sided, it is
+*  replaced by a pair of single-sided inequalities, if necessary.
+*
+*  RETURNS
+*
+*  The routine npp_reduce_ineq_coef returns the number of coefficients
+*  reduced.
+*
+*  BACKGROUND
+*
+*  Consider an inequality constraint:
+*
+*     sum  a[j] x[j] >= b.                                           (1)
+*    j in J
+*
+*  (In case of '<=' inequality it can be transformed to '>=' format by
+*  multiplying both its sides by -1.) Let x[k] be a binary variable;
+*  other variables can be integer as well as continuous. We can write
+*  constraint (1) as follows:
+*
+*     a[k] x[k] + t[k] >= b,                                         (2)
+*
+*  where:
+*
+*     t[k] = sum      a[j] x[j].                                     (3)
+*           j in J\{k}
+*
+*  Since x[k] is binary, constraint (2) is equivalent to disjunction of
+*  the following two constraints:
+*
+*     x[k] = 0,  t[k] >= b                                           (4)
+*
+*        OR
+*
+*     x[k] = 1,  t[k] >= b - a[k].                                   (5)
+*
+*  Let also that for the partial sum t[k] be known some its implied
+*  lower bound inf t[k].
+*
+*  Case a[k] > 0. Let inf t[k] < b, since otherwise both constraints
+*  (4) and (5) and therefore constraint (2) are redundant.
+*  If inf t[k] > b - a[k], only constraint (5) is redundant, in which
+*  case it can be replaced with the following redundant and therefore
+*  equivalent constraint:
+*
+*     t[k] >= b - a'[k] = inf t[k],                                  (6)
+*
+*  where:
+*
+*     a'[k] = b - inf t[k].                                          (7)
+*
+*  Thus, the original constraint (2) is equivalent to the following
+*  constraint with coefficient at variable x[k] changed:
+*
+*     a'[k] x[k] + t[k] >= b.                                        (8)
+*
+*  From inf t[k] < b it follows that a'[k] > 0, i.e. the coefficient
+*  at x[k] keeps its sign. And from inf t[k] > b - a[k] it follows that
+*  a'[k] < a[k], i.e. the coefficient reduces in magnitude.
+*
+*  Case a[k] < 0. Let inf t[k] < b - a[k], since otherwise both
+*  constraints (4) and (5) and therefore constraint (2) are redundant.
+*  If inf t[k] > b, only constraint (4) is redundant, in which case it
+*  can be replaced with the following redundant and therefore equivalent
+*  constraint:
+*
+*     t[k] >= b' = inf t[k].                                         (9)
+*
+*  Rewriting constraint (5) as follows:
+*
+*     t[k] >= b - a[k] = b' - a'[k],                                (10)
+*
+*  where:
+*
+*     a'[k] = a[k] + b' - b = a[k] + inf t[k] - b,                  (11)
+*
+*  we can see that disjunction of constraint (9) and (10) is equivalent
+*  to disjunction of constraint (4) and (5), from which it follows that
+*  the original constraint (2) is equivalent to the following constraint
+*  with both coefficient at variable x[k] and right-hand side changed:
+*
+*     a'[k] x[k] + t[k] >= b'.                                      (12)
+*
+*  From inf t[k] < b - a[k] it follows that a'[k] < 0, i.e. the
+*  coefficient at x[k] keeps its sign. And from inf t[k] > b it follows
+*  that a'[k] > a[k], i.e. the coefficient reduces in magnitude.
+*
+*  PROBLEM TRANSFORMATION
+*
+*  In the routine npp_reduce_ineq_coef the following implied lower
+*  bound of the partial sum (3) is used:
+*
+*     inf t[k] = sum       a[j] l[j] + sum       a[j] u[j],         (13)
+*               j in Jp\{k}           k in Jn\{k}
+*
+*  where Jp = {j : a[j] > 0}, Jn = {j : a[j] < 0}, l[j] and u[j] are
+*  lower and upper bounds, resp., of variable x[j].
+*
+*  In order to compute inf t[k] more efficiently, the following formula,
+*  which is equivalent to (13), is actually used:
+*
+*                ( h - a[k] l[k] = h,        if a[k] > 0,
+*     inf t[k] = <                                                  (14)
+*                ( h - a[k] u[k] = h - a[k], if a[k] < 0,
+*
+*  where:
+*
+*     h = sum   a[j] l[j] + sum   a[j] u[j]                         (15)
+*        j in Jp           j in Jn
+*
+*  is the implied lower bound of row (1).
+*
+*  Reduction of positive coefficient (a[k] > 0) does not change value
+*  of h, since l[k] = 0. In case of reduction of negative coefficient
+*  (a[k] < 0) from (11) it follows that:
+*
+*     delta a[k] = a'[k] - a[k] = inf t[k] - b  (> 0),              (16)
+*
+*  so new value of h (accounting that u[k] = 1) can be computed as
+*  follows:
+*
+*     h := h + delta a[k] = h + (inf t[k] - b).                     (17)

+*
+*  DESCRIPTION
+*
+*  The routine npp_improve_bounds analyzes specified row (inequality
+*  or equality constraint) to determine implied column bounds and then
+*  uses these bounds to improve (strengthen) current column bounds.
+*
+*  If the flag is on and current column bounds changed significantly
+*  or the column was fixed, the routine activate rows affected by the
+*  column for further processing. (This feature is intended to be used
+*  in the main loop of the routine npp_process_row.)
+*
+*  NOTE: This operation can be used for MIP problem only.
+*
+*  RETURNS
+*
+*  The routine npp_improve_bounds returns the number of significantly
+*  changed bounds plus the number of column having been fixed due to
+*  bound improvements. However, if the routine detects primal/integer
+*  infeasibility, it returns a negative value. */

+*  int npp_process_prob(NPP *npp, int hard);
+*
+*  DESCRIPTION
+*
+*  The routine npp_process_prob performs basic LP/MIP processing that
+*  currently includes:
+*
+*  1) initial LP/MIP processing (see the routine npp_clean_prob),
+*
+*  2) basic row processing (see the routine npp_process_row), and
+*
+*  3) basic column processing (see the routine npp_process_col).
+*
+*  If the flag hard is on, the routine attempts to improve current
+*  column bounds multiple times within the main processing loop, in
+*  which case this feature may take a time. Otherwise, if the flag hard
+*  is off, improving column bounds is performed only once at the end of
+*  the main loop. (Note that this feature is used for MIP only.)
+*
+*  The routine uses two sets: the set of active rows and the set of
+*  active columns. Rows/columns are marked by a flag (the field temp in
+*  NPPROW/NPPCOL). If the flag is non-zero, the row/column is active,
+*  in which case it is placed in the beginning of the row/column list;
+*  otherwise, if the flag is zero, the row/column is inactive, in which
+*  case it is placed in the end of the row/column list. If a row/column
+*  being currently processed may affect other rows/columns, the latters
+*  are activated for further processing.

+/***********************************************************************
+*  npp_sat_encode_sum_ax - encode linear combination of 0-1 variables
+*
+*  PURPOSE
+*
+*  Given a linear combination of binary variables:
+*
+*     sum a[j] x[j],                                                 (1)
+*      j
+*
+*  which is the linear form of the specified row, this routine encodes
+*  (i.e. translates to CNF) the following equality:
+*
+*                        n
+*     sum |a[j]| t[j] = sum 2**(k-1) * y[k],                         (2)
+*      j                k=1
+*
+*  where t[j] = x[j] (if a[j] > 0) or t[j] = 1 - x[j] (if a[j] < 0),
+*  and y[k] is either t[j] or a new literal created by the routine or
+*  a constant zero. Note that the sum in the right-hand side of (2) can
+*  be thought as a n-bit representation of the sum in the left-hand
+*  side, which is a non-negative integer number.
+*
+*  ALGORITHM
+*
+*  First, the number of bits, n, sufficient to represent any value in
+*  the left-hand side of (2) is determined. Obviously, n is the number
+*  of bits sufficient to represent the sum (sum |a[j]|).
+*
+*  Let
+*
+*               n
+*     |a[j]| = sum 2**(k-1) b[j,k],                                  (3)
+*              k=1
+*
+*  where b[j,k] is k-th bit in a n-bit representation of |a[j]|. Then
+*
+*                          m            n
+*     sum |a[j]| * t[j] = sum 2**(k-1) sum b[j,k] * t[j].            (4)
+*      j                  k=1          j=1
+*
+*  Introducing the set
+*
+*     J[k] = { j : b[j,k] = 1 }                                      (5)
+*
+*  allows rewriting (4) as follows:
+*
+*                          n
+*     sum |a[j]| * t[j] = sum 2**(k-1)  sum    t[j].                 (6)
+*      j                  k=1         j in J[k]
+*
+*  Thus, our goal is to provide |J[k]| <= 1 for all k, in which case
+*  we will have the representation (1).
+*
+*  Let |J[k]| = 2, i.e. J[k] has exactly two literals u and v. In this
+*  case we can apply the following transformation:
+*
+*     u + v = s + 2 * c,                                             (7)
+*
+*  where s and c are, respectively, low (sum) and high (carry) bits of
+*  the sum of two bits. This allows to replace two literals u and v in
+*  J[k] by one literal s, and carry out literal c to J[k+1].
+*
+*  If |J[k]| >= 3, i.e. J[k] has at least three literals u, v, and w,
+*  we can apply the following transformation:
+*
+*     u + v + w = s + 2 * c.                                         (8)
+*
+*  Again, literal s replaces literals u, v, and w in J[k], and literal
+*  c goes into J[k+1].
+*
+*  On exit the routine stores each literal from J[k] in element y[k],
+*  1 <= k <= n. If J[k] is empty, y[k] is set to constant false.
+*
+*  RETURNS
+*
+*  The routine returns n, the number of literals in the right-hand side
+*  of (2), 0 <= n <= NBIT_MAX. If the sum (sum |a[j]|) is too large, so
+*  more than NBIT_MAX (= 31) literals are needed to encode the original
+*  linear combination, the routine returns a negative value. */

+*
+*  where y[k] is either a literal (i.e. y[k] = x[k] or y[k] = 1 - x[k])
+*  or constant false (zero), b is a given lower bound.
+*
+*  ALGORITHM
+*
+*  If b < 0, the constraint is redundant, so assume that b >= 0. Let
+*
+*          n
+*     b = sum 2**(k-1) b[k],                                         (2)
+*         k=1
+*
+*  where b[k] is k-th binary digit of b. (Note that if b >= 2**n and
+*  therefore cannot be represented in the form (2), the constraint (1)
+*  is infeasible.) In this case the condition (1) is equivalent to the
+*  following condition:
+*
+*     y[n] y[n-1] ... y[2] y[1] >= b[n] b[n-1] ... b[2] b[1],        (3)
+*
+*  where ">=" is understood lexicographically.
+*
+*  Algorithmically the condition (3) can be tested as follows:
+*
+*     for (k = n; k >= 1; k--)
+*     {  if (y[k] < b[k])
+*           y is less than b;
+*        if (y[k] > b[k])
+*           y is greater than b;
+*     }
+*     y is equal to b;
+*
+*  Thus, y is less than b iff there exists k, 1 <= k <= n, for which

+*
+*     y[n] = b[n] AND ... AND y[k+1] = b[k+1] AND y[k] < b[k].       (4)
+*
+*  Negating the condition (4) we have that y is not less than b iff for
+*  all k, 1 <= k <= n, the following condition is satisfied:
+*
+*     y[n] != b[n] OR ... OR y[k+1] != b[k+1] OR y[k] >= b[k].       (5)
+*
+*  Note that if b[k] = 0, the literal y[k] >= b[k] is always true, in

+*  npp_sat_encode_row - encode constraint (row) of general type
+*
+*  PURPOSE
+*
+*  This routine translates to CNF the following constraint (row):

+*     L <= sum a[j] x[j] <= U,                                       (1)
+*           j
+*
+*  where all x[j] are binary variables.
+*
+*  ALGORITHM
+*
+*  First, the routine performs substitution x[j] = t[j] for j in J+
+*  and x[j] = 1 - t[j] for j in J-, where J+ = { j : a[j] > 0 } and
+*  J- = { j : a[j] < 0 }. This gives:
+*
+*     L <=  sum  a[j] t[j] +   sum  a[j] (1 - t[j]) <= U  ==>
+*         j in J+            j in J-
+*
+*     L' <= sum |a[j]| t[j] <= U',                                   (2)
+*            j

+*              j in J-                 j in J-
+*
+*  (Actually only new bounds L' and U' are computed.)
+*
+*  Then the routine translates to CNF the following equality:
+*
+*                        n
+*     sum |a[j]| t[j] = sum 2**(k-1) * y[k],                         (4)

+*
+*  where y[k] is either some t[j] or a new literal or a constant zero
+*  (see the routine npp_sat_encode_sum_ax).
+*
+*  Finally, the routine translates to CNF the following conditions:
+*
+*      n
+*     sum 2**(k-1) * y[k] >= L'                                      (5)

+*     k=1
+*
+*  (see the routines npp_sat_encode_geq and npp_sat_encode_leq).
+*
+*  All resulting clauses are encoded as cover inequalities and included

+************************************************************************
+*
+* THIS CODE IS AN IMPLEMENTATION OF THE ALGORITHM PROPOSED IN
+*
+* M. Fischetti, M. Monaci,
+* "Proximity Search for 0-1 Mixed-Integer Convex Programming"
+* Technical Report DEI, University of Padua, March 2013.
+*
+* AVAILABLE AT
+*       http://www.dei.unipd.it/~fisch/papers/proximity_search.pdf
+*
+* THE CODE HAS BEEN WRITTEN BY GIORGIO SARTOR, " 0gioker0@gmail.com "
+*
+* BASIC IDEA:
+*
+* The initial feasible solution x_tilde is defined. This initial
+* solution can be found by an ad-hoc heuristic and proxy can be used to
+* refine it by exploiting an underlying MIP model whose solution from
+* scratch turned out to be problematic. Otherwise, x_tilde can be found
+* by running the GLPK mip solver until a first feasible solution is
+* found, setting a conservative time limit of 10 minutes (by default).
+* Time limit can be modified passing variable tlim [ms].
+*
+* Then the cutoff tolerance "delta" is defined. The default tolerance
+* is 1% of the last feasible solution obj value--rounded to integer if
+* all the variables and obj coefficients are integer.
+*
+* Next, the objective function c' x is replaced by the Hamming distance
+* between x (the actual obj coefficients) and x_tilde (the given
+* solution). Distance is only computed wrt the binary variables.
+*
+* The GLPK solver is then invoked to hopefully find a new incumbent
+* x_star with cost c' x_star <= c' x_tilde - delta. A crucial property
+* here is that the root-node solution of the LP relaxation is expected
+* to be not too different from x_tilde, as this latter solution would
+* be optimal without the cutoff constraint, that for a small delta can
+* typically be fulfilled with just local adjustments.
+*
+* If no new solution x_star is found within the time limit the
+* algorithm stops. Of course, if the MIP solver proved infeasibility
+* for the given delta, we have that c' x_tilde - delta is a valid lower
+* bound (in case of minimazation) on the optimal value of the original
+* MIP.
+*
+* The new solution x_star, if any, is possibly improved by solving a
+* simplified problem (refinement) where all binary variables have been
+* fixed to their value in x_star so as to find the best solution within
+* the neighborhood.
+*
+* Finally, the approach is reapplied on x_star (that replaces x_tilde)
+* so as to recenter the distance Hamming function and by modifying the
+* cutoff tolerance delta.
+*
+* In this way, there will be a series of hopefully not-too-difficult
+* sub-MIPs to solve, each leading to an improvement of the incumbent.
+* More aggressive policies on the definition of tolerance delta can
+* lead to a better performance, but would require an ad-hoc tuning.

+* int proxy(glp_prob *lp, double *zstar, double *xstar,
+*           const double[] initsol, double rel_impr, int tlim,
+*           int verbose)
+*
+* lp       : GLPK problem pointer to a MIP with binary variables
+*
+* zstar    : the value of objective function of the best solution found
+*
+* xstar    : best solution with components xstar[1],...,xstar[ncols]
+*
+* initsol  : pointer to a initial feasible solution, see
+*            glp_ios_heur_sol
+*            If initsol = NULL, the procedure finds the first solution
+*            by itself.
+*
+* rel_impr : minimum relative obj improvement to be achieved at each
+*            internal step; if <= 0.0 a default value of 0.01 (1%) is
+*            used; for some problems (e.g., set covering with small
+*            integer costs) a more-conservative choice of 0.001 (0.1%)
+*            can lead to a better final solution; values larger than
+*            0.05 (5%) are typically too aggressive and do not work
+*            well.
+*
+* tlim     : time limit to find a new solution, in ms.
+*            If tlim = 0, it is set to its default value, 600000 ms
+*
+* verbose  : if 1 the output is activated. If 0 only errors are
+*            displayed
+*
+* The procedure returns -1 if an error occurred, 0 otherwise (possibly,
+* time limit)

+*  inv(B), should be previously computed with the routine spx_eval_rho.
+*  It is assumed that elements of this vector are stored in the array
+*  locations rho[1], ..., rho[m].
+*
+*  There exist two ways to compute the simplex table row.
+*
+*  1. T[i,j], j = 1,...,n-m, is computed as inner product:
+*
+*                    m
+*        T[i,j] = - sum a[i,k] * rho[i],

+*
+*        n1 = (n - m) * (nnz(A) / n),
+*
+*  (n - m) is the number of columns of N, nnz(A) / n is the average
+*  number of non-zeros in one column of A and, therefore, of N.
+*
+*  2. The simplex table row is computed as part of a linear combination
+*     of rows of A with coefficients rho[i] != 0. The estimated number
+*     of operations in this case is:
+*
+*        n2 = nnz(rho) * (nnz(A) / m),
+*
+*     where nnz(rho) is the number of non-zeros in the vector rho,
+*     nnz(A) / m is the average number of non-zeros in one row of A.
+*
+*  If n1 < n2, the routine computes the simples table row using the
+*  first way (like the routine spx_eval_trow). Otherwise, the routine
+*  uses the second way calling the routine spx_nt_prod1.
+*
+*  On exit components of the simplex table row are stored in the array

+*  spx_chuzr_std - choose basic variable (textbook ratio test)
+*
+*  This routine implements an improved textbook ratio test to choose
+*  basic variable xB[p].
+*
+*  The parameter phase specifies the search phase:
+*
+*  1 - searching for feasible basic solution. In this case the routine
+*      uses artificial bounds of basic variables that correspond to
+*      breakpoints of the penalty function:
+*
+*                 ( lB[i], if cB[i] = 0
+*                 (
+*        lB'[i] = { uB[i], if cB[i] > 0
+*                 (
+*                 (  -inf, if cB[i] < 0
+*
+*                 ( uB[i], if cB[i] = 0
+*                 (
+*        uB'[i] = {  +inf, if cB[i] > 0
+*                 (
+*                 ( lB[i], if cB[i] < 0
+*
+*      where lB[i] and uB[i] are original bounds of variable xB[i],
+*      cB[i] is the penalty (objective) coefficient of that variable.
+*
+*  2 - searching for optimal basic solution. In this case the routine
+*      uses original bounds of basic variables.
+*
+*  Current values of basic variables should be placed in the array
+*  locations beta[1], ..., beta[m].
+*
+*  The parameter 1 <= q <= n-m specifies the index of non-basic
+*  variable xN[q] chosen.
+*
+*  The parameter s specifies the direction in which xN[q] changes:
+*  s = +1.0 means xN[q] increases, and s = -1.0 means xN[q] decreases.
+*  (Thus, the corresponding ray parameter is theta = s (xN[q] - f[q]),
+*  where f[q] is the active bound of xN[q] in the current basis.)
+*
+*  Elements of q-th simplex table column T[q] = (t[i,q]) corresponding
+*  to non-basic variable xN[q] should be placed in the array locations
+*  tcol[1], ..., tcol[m].
+*
+*  The parameter tol_piv specifies a tolerance for elements of the
+*  simplex table column T[q]. If |t[i,q]| < tol_piv, basic variable
+*  xB[i] is skipped, i.e. it is assumed that it does not depend on the
+*  ray parameter theta.
+*
+*  The parameters tol and tol1 specify tolerances used to increase the
+*  choice freedom by simulating an artificial degeneracy as follows.
+*  If beta[i] <= lB[i] + delta[i], where delta[i] = tol + tol1 |lB[i]|,
+*  it is assumed that beta[i] is exactly the same as lB[i]. Similarly,
+*  if beta[i] >= uB[i] - delta[i], where delta[i] = tol + tol1 |uB[i]|,
+*  it is assumed that beta[i] is exactly the same as uB[i].
+*
+*  The routine determines the index 1 <= p <= m of basic variable xB[p]
+*  that reaches its (lower or upper) bound first on increasing the ray
+*  parameter theta, stores the bound flag (0 - lower bound or fixed
+*  value, 1 - upper bound) to the location pointed to by the pointer
+*  p_flag, and returns the index p. If non-basic variable xN[q] is
+*  double-bounded and reaches its opposite bound first, the routine
+*  returns (-1). And if the ray parameter may increase unlimitedly, the
+*  routine returns zero.
+*
+*  Should note that the bound flag stored to the location pointed to by
+*  p_flag corresponds to the original (not artficial) bound of variable
+*  xB[p] and defines the active bound flag lp->flag[q] to be set in the
+*  adjacent basis for that basic variable. */

+*  (This column should be computed for the current basis.)
+*
+*  First, the routine determines the increment of basic variable xB[p]
+*  in the adjacent basis (but only if 1 <= p <= m):
+*
+*                   (       - beta[p], if -inf < xB[p] < +inf

+*
+*  where beta[p] is the value of xB[p] in the current basis, lB[p] and

+*                   ( delta xB[p] / T[p,q], if 1 <= p <= m

+*
+*  where T[p,q] is the pivot element of the simplex table, f[q] is the

+*
+*  If 1 <= p <= m, in the adjacent basis xN[q] becomes xB[p], so:

+*
+*  Values of other basic variables xB[i] for 1 <= i <= m, i != p, are

+*
+*  On entry to the routine components of the vector d in the current

+*
+*  The parameter 1 <= q <= n-m specified non-basic variable xN[q] which
+*  becomes basic variable xB[p] in the adjacent basis.
+*
+*  It is assumed that the array trow contains elements of p-th (pivot)
+*  row T'[p] of the simplex table in locations trow[1], ..., trow[n-m].
+*  It is also assumed that the array tcol contains elements of q-th
+*  (pivot) column T[q] of the simple table in locations tcol[1], ...,
+*  tcol[m]. (These row and column should be computed for the current
+*  basis.)
+*

+/***********************************************************************
+*  The structure SPXLP describes LP problem and its current basis.
+*
+*  It is assumed that LP problem has the following formulation (this is
+*  so called "working format"):
+*
+*     z = c'* x + c0 -> min                                          (1)
+*
+*     A * x = b                                                      (2)
+*
+*     l <= x <= u                                                    (3)
+*
+*  where:
+*
+*  x = (x[k]) is a n-vector of variables;
+*
+*  z is an objective function;
+*
+*  c = (c[k]) is a n-vector of objective coefficients;
+*
+*  c0 is a constant term of the objective function;
+*
+*  A = (a[i,k]) is a mxn-matrix of constraint coefficients;
+*
+*  b = (b[i]) is a m-vector of right-hand sides;
+*
+*  l = (l[k]) is a n-vector of lower bounds of variables;
+*
+*  u = (u[k]) is a n-vector of upper bounds of variables.
+*
+*  If variable x[k] has no lower (upper) bound, it is formally assumed
+*  that l[k] = -inf (u[k] = +inf). Variable having no bounds is called
+*  free (unbounded) variable. If l[k] = u[k], variable x[k] is assumed
+*  to be fixed.
+*
+*  It is also assumed that matrix A has full row rank: rank(A) = m,
+*  i.e. all its rows are linearly independent, so m <= n.
+*
+*  The (current) basis is defined by an appropriate permutation matrix
+*  P of order n such that:
+*
+*             ( xB )
+*     P * x = (    ),                                                (4)
+*             ( xN )
+*
+*  where xB = (xB[i]) is a m-vector of basic variables, xN = (xN[j]) is
+*  a (n-m)-vector of non-basic variables. If a non-basic variable xN[j]
+*  has both lower and upper bounds, there is used an additional flag to
+*  indicate which bound is active.
+*
+*  From (2) and (4) it follows that:
+*
+*     A * P'* P * x = b   <=>   B * xB + N * xN = b,                 (5)
+*
+*  where P' is a matrix transposed to P, and
+*
+*     A * P' = (B | N).                                              (6)
+*
+*  Here B is the basis matrix, which is a square non-singular matrix
+*  of order m composed from columns of matrix A that correspond to
+*  basic variables xB, and N is a mx(n-m) matrix composed from columns
+*  of matrix A that correspond to non-basic variables xN. */

+*  On exit the routine stores information about correspondence between

+*  the original LP corresponds to variable x[k] of the working LP, and
+*  the upper bound of that variable was shifted to zero;
+*
+*  map[i] = 0, 1 <= i <= P->m, means that i-th auxiliary variable of
+*  the original LP was excluded from the working LP;

+*  variable xB[p] chosen: s = +1.0 means that xB[p] violates its lower
+*  bound, so dual non-basic variable lambdaB[p] = lambda^+B[p]
+*  increases, and s = -1.0 means that xB[p] violates its upper bound,
+*  so dual non-basic variable lambdaB[p] = lambda^-B[p] decreases.
+*  (Thus, the dual ray parameter theta = s * lambdaB[p] >= 0.)
+#else
+*  The parameter r specifies the bound violation for basic variable
+*  xB[p] chosen:
+*
+*  r = lB[p] - beta[p] > 0 means that xB[p] violates its lower bound,
+*  so dual non-basic variable lambdaB[p] = lambda^+B[p] increases; and
+*
+*  r = uB[p] - beta[p] < 0 means that xB[p] violates its upper bound,
+*  so dual non-basic variable lambdaB[p] = lambda^-B[p] decreases.
+*
+*  (Note that r is the dual reduced cost of lambdaB[p].)
+#endif
+*
+*  Elements of p-th simplex table row t[p] = (t[p,j]) corresponding
+*  to basic variable xB[p] should be placed in the array locations
+*  trow[1], ..., trow[n-m].
+*
+*  The parameter tol_piv specifies a tolerance for elements of the
+*  simplex table row t[p]. If |t[p,j]| < tol_piv, dual basic variable
+*  lambdaN[j] is skipped, i.e. it is assumed that it does not depend on
+*  the dual ray parameter theta.
+*
+*  The parameters tol and tol1 specify tolerances used to increase the
+*  choice freedom by simulating an artificial degeneracy as follows.
+*  If lambdaN[j] = lambda^+N[j] >= 0 and d[j] <= +delta[j], or if
+*  lambdaN[j] = lambda^-N[j] <= 0 and d[j] >= -delta[j], where
+*  delta[j] = tol + tol1 * |cN[j]|, cN[j] is objective coefficient at
+*  xN[j], then it is assumed that reduced cost d[j] is equal to zero.
+*
+*  The routine determines the index 1 <= q <= n-m of non-basic variable
+*  xN[q], for which corresponding dual basic variable lambda^+N[j] or
+*  lambda^-N[j] reaches its zero bound first on increasing the dual ray
+*  parameter theta, and returns p on exit. And if theta may increase

+*  cost of non-basic dual variable lambda^+B[i] >= 0, so increasing it
+*  increases the dual objective. Similarly, negative bound violation
+*  rn[i] = ub[i] - beta[i] < 0 is the reduced cost of non-basic dual
+*  variable lambda^-B[i] <= 0, so decreasing it also increases the dual
+*  objective.
+*
+*  Current values of basic variables should be placed in the array
+*  locations beta[1], ..., beta[m].
+*
+*  Basic variable xB[i] is considered eligible, if:

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+
+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2010 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       code lengths are lens[0..codes-1].  Each length corresponds to the

+       symbols by length from short to long, and retaining the symbol order
+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer

+       increases.  For the deflate format, these bits are stored backwards

+       decoding tables are built in the large loop below, the integer codes
+       are incremented backwards.
+

+
+       The codes are sorted by computing a count of codes for each length,

+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip streams in memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in case of corrupted input.

+     The application must update next_in and avail_in when avail_in has dropped
+   to zero.  It must update next_out and avail_out when avail_out has dropped
+   to zero.  The application must initialize zalloc, zfree and opaque before
+   calling the init function.  All other fields are set by the compression
+   library and must not be updated by the application.
+
+     The opaque value provided by the application will be passed as the first
+   parameter for calls of zalloc and zfree.  This can be useful for custom
+   memory management.  The compression library attaches no meaning to the
+   opaque value.
+
+     zalloc must return Z_NULL if there is not enough memory for the object.
+   If zlib is used in a multi-threaded application, zalloc and zfree must be
+   thread safe.
+
+     On 16-bit systems, the functions zalloc and zfree must be able to allocate
+   exactly 65536 bytes, but will not be required to allocate more than this if
+   the symbol MAXSEG_64K is defined (see zconf.h).  WARNING: On MSDOS, pointers
+   returned by zalloc for objects of exactly 65536 bytes *must* have their
+   offset normalized to zero.  The default allocation function provided by this
+   library ensures this (see zutil.c).  To reduce memory requirements and avoid
+   any allocation of 64K objects, at the expense of compression ratio, compile
+   the library with -DMAX_WBITS=14 (see zconf.h).
+
+     The fields total_in and total_out can be used for statistics or progress
+   reports.  After compression, total_in holds the total size of the
+   uncompressed data and may be saved for use in the decompressor (particularly
+   if the decompressor wants to decompress everything in a single step).

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).  Some
+    output may be provided even if flush is not set.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed code
+  block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error.  After
+  deflate has returned Z_STREAM_END, the only possible operations on the stream
+  are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step.  In this case, avail_out must be at least the
+  value returned by deflateBound (see below).  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT).  In doubt, the data is considered
+  binary.  This field is only for information purposes and does not affect the
+  compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not

+    resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all the uncompressed data.  (The size
+  of the uncompressed data may have been saved by the compressor for this
+  purpose.) The next operation on this stream must be inflateEnd to deallocate
+  the decompression state.  The use of Z_FINISH is never required, but can be
+  used to inform inflate that a faster approach may be used for the single
+  inflate() call.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the only effect of the flush parameter in this implementation
+  is on the return value of inflate(), as noted below, or when it returns early
+  because Z_BLOCK or Z_TREES is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the adler32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the adler32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained, so applications that need that information should
+  instead use raw inflate, see inflateInit2() below, or inflateBack() and
+  perform their own processing of the gzip header and trailer.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+  output buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is desired.

+
+     This is another version of deflateInit with more compression options.  The
+   fields next_in, zalloc, zfree and opaque must be initialized before by the
+   caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute an adler32 check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to 255 (unknown).  If a
+   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

+     This is another version of inflateInit with an extra parameter.  The
+   fields next_in, avail_in, zalloc, zfree and opaque must be initialized
+   before by the caller.
+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library.  The default value is 15 if inflateInit is used
+   instead.  windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if
+   deflateInit2() was not used.  If a compressed stream with a larger window
+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be zero to request that inflate use the window size in
+   the zlib header of the compressed stream.
+
+     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
+   determines the window size.  inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream.  This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values.  If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an adler32 or a crc32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is.  Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding.  Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is more efficient than inflate() for
+   file i/o applications in that it avoids copying between the output and the
+   sliding window by simply making the window itself the output buffer.  This
+   function trusts the application to not change the output buffer passed by
+   the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the normal
+   behavior of inflate(), which expects either a zlib or gzip header and
+   trailer around the deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero--buf is ignored in that
+   case--and inflateBack() will return a buffer error.  inflateBack() will call
+   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
+   should return zero on success, or non-zero on failure.  If out() returns
+   non-zero, inflateBack() will return with an error.  Neither in() nor out()
+   are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is

+MiniSat-C v1.14.1
+========================================
+
+* Fixed some serious bugs. 
+* Tweaked to be Visual Studio friendly (by Alan Mishchenko).
+  This disabled reading of gzipped DIMACS files and signal handling, but none
+  of these features are essential (and easy to re-enable, if wanted).
+
+MiniSat-C v1.14
+========================================
+
+Ok, we get it. You hate C++. You hate templates. We agree; C++ is a
+seriously messed up language. Although we are more pragmatic about the
+quirks and maldesigns in C++, we sympathize with you. So here is a
+pure C version of MiniSat, put together by Niklas Sörensson.

+
+/*
+ * TIFF Library.
+ * LogLuv compression support for high dynamic range images.
+ *
+ * Contributed by Greg Larson.
+ *
+ * LogLuv image support uses the TIFF library to store 16 or 10-bit
+ * log luminance values with 8 bits each of u and v or a 14-bit index.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit integer values.  A 16-bit luminance is interpreted
+ * as a sign bit followed by a 15-bit integer that is converted
+ * to and from a linear magnitude using the transformation:
+ *
+ *	L = 2^( (Le+.5)/256 - 64 )		# real from 15-bit
+ *
+ *	Le = floor( 256*(log2(L) + 64) )	# 15-bit from real
+ *
+ * The actual conversion to world luminance units in candelas per sq. meter
+ * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
+ * This value is usually set such that a reasonable exposure comes from
+ * clamping decoded luminances above 1 to 1 in the displayed image.
+ *
+ * The 16-bit values for u and v may be converted to real values by dividing
+ * each by 32768.  (This allows for negative values, which aren't useful as
+ * far as we know, but are left in case of future improvements in human
+ * color vision.)
+ *
+ * Conversion from (u,v), which is actually the CIE (u',v') system for
+ * you color scientists, is accomplished by the following transformation:
+ *
+ *	u = 4*x / (-2*x + 12*y + 3)
+ *	v = 9*y / (-2*x + 12*y + 3)
+ *
+ *	x = 9*u / (6*u - 16*v + 12)
+ *	y = 4*v / (6*u - 16*v + 12)
+ *
+ * This process is greatly simplified by passing 32-bit IEEE floats
+ * for each of three CIE XYZ coordinates.  The codec then takes care
+ * of conversion to and from LogLuv, though the application is still
+ * responsible for interpreting the TIFFTAG_STONITS calibration factor.
+ *
+ * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
+ * point of (x,y)=(1/3,1/3).  However, most color systems assume some other
+ * white point, such as D65, and an absolute color conversion to XYZ then
+ * to another color space with a different white point may introduce an
+ * unwanted color cast to the image.  It is often desirable, therefore, to
+ * perform a white point conversion that maps the input white to [1 1 1]
+ * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
+ * tag value.  A decoder that demands absolute color calibration may use
+ * this white point tag to get back the original colors, but usually it
+ * will be ignored and the new white point will be used instead that
+ * matches the output color space.
+ *
+ * Pixel information is compressed into one of two basic encodings, depending
+ * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
+ * or COMPRESSION_SGILOG24.  For COMPRESSION_SGILOG, greyscale data is
+ * stored as:
+ *
+ *	 1       15
+ *	|-+---------------|
+ *
+ * COMPRESSION_SGILOG color data is stored as:
+ *
+ *	 1       15           8        8
+ *	|-+---------------|--------+--------|
+ *	 S       Le           ue       ve
+ *
+ * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
+ *
+ *	     10           14
+ *	|----------|--------------|
+ *	     Le'          Ce
+ *
+ * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
+ * encoded as an index for optimal color resolution.  The 10 log bits are
+ * defined by the following conversions:
+ *
+ *	L = 2^((Le'+.5)/64 - 12)		# real from 10-bit
+ *
+ *	Le' = floor( 64*(log2(L) + 12) )	# 10-bit from real
+ *
+ * The 10 bits of the smaller format may be converted into the 15 bits of
+ * the larger format by multiplying by 4 and adding 13314.  Obviously,
+ * a smaller range of magnitudes is covered (about 5 orders of magnitude
+ * instead of 38), and the lack of a sign bit means that negative luminances
+ * are not allowed.  (Well, they aren't allowed in the real world, either,
+ * but they are useful for certain types of image processing.)
+ *
+ * The desired user format is controlled by the setting the internal
+ * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float XYZ values
+ *  SGILOGDATAFMT_16BIT	      = 16-bit integer encodings of logL, u and v
+ * Raw data i/o is also possible using:
+ *  SGILOGDATAFMT_RAW         = 32-bit unsigned integer with encoded pixel
+ * In addition, the following decoding is provided for ease of display:
+ *  SGILOGDATAFMT_8BIT        = 8-bit default RGB gamma-corrected values
+ *
+ * For grayscale images, we provide the following data formats:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float Y values
+ *  SGILOGDATAFMT_16BIT       = 16-bit integer w/ encoded luminance
+ *  SGILOGDATAFMT_8BIT        = 8-bit gray monitor values
+ *
+ * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
+ * scheme by separating the logL, u and v bytes for each row and applying
+ * a PackBits type of compression.  Since the 24-bit encoding is not
+ * adaptive, the 32-bit color format takes less space in many cases.
+ *
+ * Further control is provided over the conversion from higher-resolution
+ * formats to final encoded values through the pseudo tag
+ * TIFFTAG_SGILOGENCODE:
+ *  SGILOGENCODE_NODITHER     = do not dither encoded values
+ *  SGILOGENCODE_RANDITHER    = apply random dithering during encoding
+ *
+ * The default value of this tag is SGILOGENCODE_NODITHER for
+ * COMPRESSION_SGILOG to maximize run-length encoding and
+ * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
+ * quantization errors into noise.

+/* What is what, and what is not?
+
+   This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
+   stream, if any, followed by the strile data, if any. This stream is read in
+   OJPEGReadByte and related functions.
+
+   It analyzes the start of this stream, until it encounters non-marker data, i.e.
+   compressed image data. Some of the header markers it sees have no actual content,
+   like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
+   other markers do have content, and the valuable bits and pieces of information
+   in these markers are saved, checking all to verify that the stream is more or
+   less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
+   functions.
+
+   Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
+   up on if we've seen no SOF marker when we're at the start of the compressed image
+   data. In this case, the tables are read from JpegXxxTables tags, and the other
+   bits and pieces of information is initialized to its most basic value. This is
+   implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
+
+   When this is complete, a good and valid JPEG header can be assembled, and this is
+   passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
+   the compressed image data, can be passed through unchanged. This is done in
+   OJPEGWriteStream functions.
+
+   LibTiff rightly expects to know the subsampling values before decompression. Just like
+   in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
+   tag is notoriously unreliable. To correct these tag values with the ones inside
+   the JPEG stream, the first part of the input stream is pre-scanned in
+   OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
+   or errors, up to the point where either these values are read, or it's clear they
+   aren't there. This means that some of the data is read twice, but we feel speed
+   in correcting these values is important enough to warrant this sacrifice. Although
+   there is currently no define or other configuration mechanism to disable this behaviour,
+   the actual header scanning is build to robustly respond with error report if it
+   should encounter an uncorrected mismatch of subsampling values. See
+   OJPEGReadHeaderInfoSecStreamSof.
+
+   The restart interval and restart markers are the most tricky part... The restart
+   interval can be specified in a tag. It can also be set inside the input JPEG stream.
+   It can be used inside the input JPEG stream. If reading from strile data, we've
+   consistently discovered the need to insert restart markers in between the different
+   striles, as is also probably the most likely interpretation of the original TIFF 6.0
+   specification. With all this setting of interval, and actual use of markers that is not
+   predictable at the time of valid JPEG header assembly, the restart thing may turn
+   out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
+   succeed in reading back what they write, which may be the reason why we've been able
+   to discover ways that seem to work.
+
+   Some special provision is made for planarconfig separate OJPEG files. These seem
+   to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
+   and plane. This may or may not be a valid JPEG configuration, we don't know and don't
+   care. We want LibTiff to be able to access the planes individually, without huge
+   buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
+   case, that allow us to pass a single plane such that LibJpeg sees a valid
+   single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
+   planes, is done inside OJPEGReadSecondarySos.
+
+   The benefit of the scheme is... that it works, basically. We know of no other that
+   does. It works without checking software tag, or otherwise going about things in an
+   OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
+   with and without JpegInterchangeFormat, with and without striles, with part of
+   the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
+   and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
+   of the data.
+
+   Another nice side-effect is that a complete JPEG single valid stream is build if
+   planarconfig is not separate (vast majority). We may one day use that to build
+   converters to JPEG, and/or to new-style JPEG compression inside TIFF.
+
+   A disadvantage is the lack of random access to the individual striles. This is the
+   reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
+   Applications would do well accessing all striles in order, as this will result in
+   a single sequential scan of the input stream, and no restarting of LibJpeg decoding
+   session.

+	 * TIFF but only supports some brain dead idea of what the
+	 * vendor thinks TIFF is):
+	 *
+	 * 'l' use little-endian byte order for creating a file
+	 * 'b' use big-endian byte order for creating a file
+	 * 'L' read/write information using LSB2MSB bit order
+	 * 'B' read/write information using MSB2LSB bit order
+	 * 'H' read/write information using host bit order
+	 * 'M' enable use of memory-mapped files when supported
+	 * 'm' disable use of memory-mapped files
+	 * 'C' enable strip chopping support when reading
+	 * 'c' disable strip chopping support
+	 * 'h' read TIFF header only, do not load the first IFD
+	 * '4' ClassicTIFF for creating a file (default)
+	 * '8' BigTIFF for creating a file
+	 *
+	 * The use of the 'l' and 'b' flags is strongly discouraged.
+	 * These flags are provided solely because numerous vendors,
+	 * typically on the PC, do not correctly support TIFF; they
+	 * only support the Intel little-endian byte order.  This
+	 * support is not configured by default because it supports
+	 * the violation of the TIFF spec that says that readers *MUST*
+	 * support both byte orders.  It is strongly recommended that
+	 * you not use this feature except to deal with busted apps
+	 * that write invalid TIFF.  And even in those cases you should
+	 * bang on the vendors to fix their software.
+	 *
+	 * The 'L', 'B', and 'H' flags are intended for applications
+	 * that can optimize operations on data by using a particular
+	 * bit order.  By default the library returns data in MSB2LSB
+	 * bit order for compatibility with older versions of this
+	 * library.  Returning data in the bit order of the native CPU
+	 * makes the most sense but also requires applications to check
+	 * the value of the FillOrder tag; something they probably do
+	 * not do right now.
+	 *
+	 * The 'M' and 'm' flags are provided because some virtual memory
+	 * systems exhibit poor behaviour when large images are mapped.
+	 * These options permit clients to control the use of memory-mapped
+	 * files on a per-file basis.
+	 *
+	 * The 'C' and 'c' flags are provided because the library support
+	 * for chopping up large strips into multiple smaller strips is not
+	 * application-transparent and as such can cause problems.  The 'c'
+	 * option permits applications that only want to look at the tags,
+	 * for example, to get the unadulterated TIFF tag information.

+ * TIFF Library.
+ * PixarLog Compression Support
+ *
+ * Contributed by Dan McCoy.
+ *
+ * PixarLog film support uses the TIFF library to store companded
+ * 11 bit values into a tiff file, which are compressed using the 
+ * zip compressor.  
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit or 8-bit unsigned integer values.
+ *
+ * On writing any of the above are converted into the internal
+ * 11-bit log format.   In the case of  8 and 16 bit values, the
+ * input is assumed to be unsigned linear color values that represent
+ * the range 0-1.  In the case of IEEE values, the 0-1 range is assumed to
+ * be the normal linear color range, in addition over 1 values are
+ * accepted up to a value of about 25.0 to encode "hot" highlights and such.
+ * The encoding is lossless for 8-bit values, slightly lossy for the
+ * other bit depths.  The actual color precision should be better
+ * than the human eye can perceive with extra room to allow for
+ * error introduced by further image computation.  As with any quantized
+ * color format, it is possible to perform image calculations which
+ * expose the quantization error. This format should certainly be less 
+ * susceptible to such errors than standard 8-bit encodings, but more
+ * susceptible than straight 16-bit or 32-bit encodings.
+ *
+ * On reading the internal format is converted to the desired output format.
+ * The program can request which format it desires by setting the internal
+ * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
+ *  PIXARLOGDATAFMT_FLOAT     = provide IEEE float values.
+ *  PIXARLOGDATAFMT_16BIT     = provide unsigned 16-bit integer values
+ *  PIXARLOGDATAFMT_8BIT      = provide unsigned 8-bit integer values
+ *
+ * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
+ * values with the difference that if there are exactly three or four channels
+ * (rgb or rgba) it swaps the channel order (bgr or abgr).
+ *
+ * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
+ * packed in 16-bit values.   However no tools are supplied for interpreting
+ * these values.
+ *
+ * "hot" (over 1.0) areas written in floating point get clamped to
+ * 1.0 in the integer data types.
+ *
+ * When the file is closed after writing, the bit depth and sample format
+ * are set always to appear as if 8-bit data has been written into it.
+ * That way a naive program unaware of the particulars of the encoding
+ * gets the format it is most likely able to handle.
+ *
+ * The codec does it's own horizontal differencing step on the coded
+ * values so the libraries predictor stuff should be turned off.
+ * The codec also handle byte swapping the encoded values as necessary
+ * since the library does not have the information necessary
+ * to know the bit depth of the raw unencoded buffer.
+ *
+ * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc.
+ * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT
+ * as noted in http://trac.osgeo.org/gdal/ticket/3894.   FrankW - Jan'11

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

+   information required to do the read or write, as well as accumulated
+   information on the input and output such as totals and check values.
+
+   in() should return zero on failure.  out() should return non-zero on
+   failure.  If either in() or out() fails, than inflateBack() returns a
+   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it

+/*
+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2016 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       Process a set of code lengths to create a canonical Huffman code.  The
+       code lengths are lens[0..codes-1].  Each length corresponds to the
+       symbols 0..codes-1.  The Huffman code is generated by first sorting the
+       symbols by length from short to long, and retaining the symbol order
+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer
+       increments for the same length, and zeros are appended as the length
+       increases.  For the deflate format, these bits are stored backwards
+       from their more natural integer increment ordering, and so when the
+       decoding tables are built in the large loop below, the integer codes
+       are incremented backwards.
+
+       This routine assumes, but does not check, that all of the entries in
+       lens[] are in the range 0..MAXBITS.  The caller must assure this.
+       1..MAXBITS is interpreted as that code length.  zero means that that
+       symbol does not occur in this code.
+
+       The codes are sorted by computing a count of codes for each length,
+       creating from that a table of starting indices for each length in the
+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any

+

+       the initial root table size constants.  See the comments in inftrees.h
+       for more information.

+ *  ALGORITHM
+ *
+ *      The "deflation" process uses several Huffman trees. The more
+ *      common source values are represented by shorter bit sequences.
+ *
+ *      Each code tree is stored in a compressed form which is itself
+ * a Huffman encoding of the lengths of all the code strings (in
+ * ascending order by source values).  The actual code strings are
+ * reconstructed from the lengths in the inflate process, as described
+ * in the deflate specification.

+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip and raw deflate streams in
+  memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in the case of corrupted input.

+   Z_NULL on entry to the initialization function, they are set to internal
+   routines that use the standard library functions malloc() and free().
+
+     On 16-bit systems, the functions zalloc and zfree must be able to allocate
+   exactly 65536 bytes, but will not be required to allocate more than this if
+   the symbol MAXSEG_64K is defined (see zconf.h).  WARNING: On MSDOS, pointers
+   returned by zalloc for objects of exactly 65536 bytes *must* have their
+   offset normalized to zero.  The default allocation function provided by this
+   library ensures this (see zutil.c).  To reduce memory requirements and avoid
+   any allocation of 64K objects, at the expense of compression ratio, compile
+   the library with -DMAX_WBITS=14 (see zconf.h).
+
+     The fields total_in and total_out can be used for statistics or progress
+   reports.  After compression, total_in holds the total size of the
+   uncompressed data and may be saved for use by the decompressor (particularly
+   if the decompressor wants to decompress everything in a single step).

+/*
+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary.  Some output may be provided even if
+    flush is zero.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending. See deflatePending(),
+  which can be used if desired to determine whether or not there is more ouput
+  in that case.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed
+  codes block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space.  If deflate returns with Z_OK or Z_BUF_ERROR, this
+  function must be called again with Z_FINISH and more output space (updated
+  avail_out) but no more input data, until it returns with Z_STREAM_END or an
+  error.  After deflate has returned Z_STREAM_END, the only possible operations
+  on the stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used in the first deflate call after deflateInit if all the
+  compression is to be done in a single step.  In order to complete in one
+  call, avail_out must be at least the value returned by deflateBound (see
+  below).  Then deflate is guaranteed to return Z_STREAM_END.  If not enough
+  output space is provided, deflate will not return Z_STREAM_END, and it must
+  be called again as described above.
+
+    deflate() sets strm->adler to the Adler-32 checksum of all input read
+  so far (that is, total_in bytes).  If a gzip stream is being generated, then
+  strm->adler will be the CRC-32 checksum of the input read so far.  (See
+  deflateInit2 below.)
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT).  If in doubt, the data is
+  considered binary.  This field is only for information purposes and does not
+  affect the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was Z_NULL or the state was inadvertently written over
+  by the application), or Z_BUF_ERROR if no progress is possible (for example
+  avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not fatal, and
+  deflate() can be called again with more input and more output space to

+ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
+/*
+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), then next_in and avail_in are updated
+    accordingly, and processing will resume at this point for the next call of
+    inflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  If the
+  caller of inflate() does not provide both available input and available
+  output space, it is possible that there will be no progress made.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  To assist in this, on return inflate() always sets strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all of the uncompressed data for the
+  operation to complete.  (The size of the uncompressed data may have been
+  saved by the compressor for this purpose.)  The use of Z_FINISH is not
+  required to perform an inflation in one step.  However it may be used to
+  inform inflate that a faster approach can be used for the single inflate()
+  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
+  stream completes, which reduces inflate's memory footprint.  If the stream
+  does not complete, either because not all of the stream is provided or not
+  enough output space is provided, then a sliding window will be allocated and
+  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+  been used.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the effects of the flush parameter in this implementation are
+  on the return value of inflate() as noted below, when inflate() returns early
+  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+  memory for a sliding window when Z_FINISH is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the Adler-32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed Adler-32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained unless inflateGetHeader() is used.  When processing
+  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+  produced so far.  The CRC-32 is checked against the gzip trailer, as is the
+  uncompressed length, modulo 2^32.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value, in which case strm->msg points to a string with a more specific
+  error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL, or the state was inadvertently written over
+  by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
+  if no progress was possible or if there was not enough room in the output
+  buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is to be attempted.

+
+     This is another version of deflateInit with more compression options.  The
+   fields next_in, zalloc, zfree and opaque must be initialized before by the
+   caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     For the current implementation of deflate(), a windowBits value of 8 (a
+   window size of 256 bytes) is not supported.  As a result, a request for 8
+   will result in 9 (a 512-byte window).  In that case, providing 8 to
+   inflateInit2() will result in an error when the zlib header with 9 is
+   checked against the initialization of inflate().  The remedy is to not use 8
+   with deflateInit2() with this initialization, or at least in that case use 9
+   with inflateInit2().
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute a check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to the appropriate value,
+   if the operating system was determined at compile time.  If a gzip stream is
+   being written, strm->adler is a CRC-32 instead of an Adler-32.
+
+     For raw deflate or gzip encoding, a request for a 256-byte window is
+   rejected as invalid, since only the zlib header provides a means of
+   transmitting the window size to the decompressor.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
+   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
+   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is
+   set to null if there is no error message.  deflateInit2 does not perform any

+   compressor and decompressor must use exactly the same dictionary (see

+
+     The dictionary should consist of strings (byte sequences) that are likely

+
+     This is another version of inflateInit with an extra parameter.  The
+   fields next_in, avail_in, zalloc, zfree and opaque must be initialized
+   before by the caller.
+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library.  The default value is 15 if inflateInit is used
+   instead.  windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if
+   deflateInit2() was not used.  If a compressed stream with a larger window
+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be zero to request that inflate use the window size in
+   the zlib header of the compressed stream.
+
+     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
+   determines the window size.  inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream.  This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values.  If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an Adler-32 or a CRC-32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is.  Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding.  Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will
+   return a Z_DATA_ERROR).  If a gzip stream is being decoded, strm->adler is a
+   CRC-32 instead of an Adler-32.  Unlike the gunzip utility and gzread() (see
+   below), inflate() will not automatically decode concatenated gzip streams.
+   inflate() will return Z_STREAM_END at the end of the gzip stream.  The state
+   would need to be reset to continue decoding a subsequent gzip stream.
+
+     inflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_VERSION_ERROR if the zlib library version is incompatible with the
+   version assumed by the caller, or Z_STREAM_ERROR if the parameters are
+   invalid, such as a null pointer to the structure.  msg is set to null if
+   there is no error message.  inflateInit2 does not perform any decompression
+   apart from possibly reading the zlib header if present: actual decompression
+   will be done by inflate().  (So next_in and avail_in may be modified, but
+   next_out and avail_out are unused and unchanged.) The current implementation
+   of inflateInit2() does not process any header information -- that is

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is potentially more efficient than
+   inflate() for file i/o applications, in that it avoids copying between the
+   output and the sliding window by simply making the window itself the output
+   buffer.  inflate() can be faster on modern CPUs when used with large
+   buffers.  inflateBack() trusts the application to not change the output
+   buffer passed by the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the default
+   behavior of inflate(), which expects a zlib header and trailer around the
+   deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero -- buf is ignored in that
+   case -- and inflateBack() will return a buffer error.  inflateBack() will
+   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
+   out() should return zero on success, or non-zero on failure.  If out()
+   returns non-zero, inflateBack() will return with an error.  Neither in() nor
+   out() are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.)  Note that inflateBack()

+rules.mk contains generic rules to compile with gcc and ccomp, with different
+optimizations, and producing different binaries. It also produces a
+measures.csv file containing the different timings given by the bench.
 
-## Just to be compiled
-- frame_pointer
+Up to 5 different optimizations can be used.
 
-## Benches to fix
-- BearSSL : does not compile (to fix)
-- ncompress : error on comparing
-- ocaml : error during postpass scheduling
-- micro-bunzip : -O3 buggy with gcc ?
-- mod_int_mat : does not include rules.mk
-- pcre2test : Trap MEMORY ACCESS VIOLATION sur le binaire ccomp
-- picosat : compilation error : implicit declaration
+To use this rule.mk, create a folder, put inside all the .c/.h source files,
+and write a Makefile ressembling:
+```make
+TARGET=float_mat
+MEASURES="c1 c2 c3 c4 c5 c6 c7 c8"
 
-## Benches that work
-- binary_search
-- bitsliced-aes
-- bitsliced-tea
-- complex
-- float_mat
-- glibc_qsort
-- heapsort
-- idea
-- number_theoretic_transform
-- quicksort
-- sha-2
-- tacle-bench-lift
-- tacle-bench-powerwindow
-- ternary
-- too_slow
+include ../rules.mk
+```
+
+This is all that is required to write, the rules.mk handles everything.
+
+There is the possibility to define some variables to finetune what you want.
+For instance, `ALL_CFILES` describes the .c source files whose objects are
+to be linked.
+
+Here is an exhaustive list of the variables:
+- `TARGET`: name of the binary to produce
+- `MEASURES`: list of the different timings. This supposes that the program
+prints something of the form "c3 cycles: 44131" for instance. In the above
+example, the Makefile would generate such a line:
+```
+float_mat c3,  1504675,  751514,  553235, 1929369,  1372441 
+```
+- `ALL_CFILES`: list of .c files to compile. By default, `$(wildcard *.c)`
+- `CLOCK`: basename of the clock file to compile. Default `../clock`
+- `ALL_CFLAGS`: cflags that are to be included for all compilers
+- `ALL_GCCFLAGS`: same, but GCC specific
+- `ALL_CCOMPFLAGS`: same, but ccomp specific
+- `K1C_CC`: GCC compiler (default k1-cos-gcc)
+- `K1C_CCOMP`: compcert compiler (default ccomp)
+- `EXECUTE_CYCLES`: running command (default `k1-cluster` with some options)
+- `GCCiFLAGS` with i from 0 to 4: the wanted optimizations. If one of these flags is empty, nothing is done. Same for `CCOMPiFLAGS`. For now, the default values:
+```
+# You can define up to GCC4FLAGS and CCOMP4FLAGS
+GCC0FLAGS?=
+GCC1FLAGS?=$(ALL_GCCFLAGS) -O1
+GCC2FLAGS?=$(ALL_GCCFLAGS) -O2
+GCC3FLAGS?=$(ALL_GCCFLAGS) -O3
+GCC4FLAGS?=
+CCOMP0FLAGS?=
+CCOMP1FLAGS?=$(ALL_CCOMPFLAGS) -fno-postpass
+CCOMP2FLAGS?=$(ALL_CCOMPFLAGS)
+CCOMP3FLAGS?=
+CCOMP4FLAGS?=
+
+# Prefix names
+GCC0PREFIX?=
+GCC1PREFIX?=.gcc.o1
+GCC2PREFIX?=.gcc.o2
+GCC3PREFIX?=.gcc.o3
+GCC4PREFIX?=
+CCOMP0PREFIX?=
+CCOMP1PREFIX?=.ccomp.o1
+CCOMP2PREFIX?=.ccomp.o2
+CCOMP3PREFIX?=
+CCOMP4PREFIX?= 
+```
+
+The `PREFIX` are the prefixes to add to the .s, .o, etc.. You should be careful that if a FLAGS is set, then the according PREFIX should be set as well.
+
+Assembly files will be generated in `asm/`, objects in `obj/`, binaries in `bin/` and outputs in `out/`.
+
+To compile and execute all the benches : `make`

-TODO - how to add timings
+To add a timing, you must use the functions whose prototypes are in `clock.h`
+
+    #include "../clock.h"
+    /* ... */
+    clock_prepare();
+    /* ... */
+    clock_start();
+    /* .. computations .. */
+    clock_stop();
+    /* ... */
+    print_total_clock(); // print to stdout
+    printerr_total_clock(); // print to stderr
+
+If the benchmark doesn't use `stdout` in a binary way you can use `print_total_clock()`. However, some benchmarks like `jpeg-6b` print their binary content to `stdout`, which then messes up the `grep` command when attempting to use it to extract the cycles from `stdout`.
+
+The solution is then to use `printerr_total_clock()` which will print the cycles to `stderr`, and use `EXECUTE_ARGS` ressembling this:
+
+    EXECUTE_ARGS=-dct int -outfile __BASE__.jpg testimg.ppm 2> __BASE__.out
+
+`__BASE__` is a macro that gets expanded to the base name - that is, the `TARGET` concatenated with one of the `GCCiPREFIX` or `CCOMPiPREFIX`. For instance, in `jpeg-6b`, `__BASE__` could be `jpeg-6b.ccomp.o2`.
