+*          Lempel, Ziv, Storer, and Szymanski Encoding and Decoding
+*
+*   File    : lzlocal.h
+*   Purpose : Internal headers for LZSS encode and decode routines.
+*             Contains the prototypes to be used by the different match
+*             finding algorithms.

+*   Revision 1.5  2007/09/20 04:34:25  michael
+*   Changes required for LGPL v3.
+*
+*   Revision 1.4  2006/12/26 04:09:09  michael
+*   Updated e-mail address and minor text clean-up.
+*
+*   Revision 1.3  2005/12/28 05:58:52  michael

+*
+*   Revision 1.2  2004/11/08 05:54:18  michael
+*   1. Split encode and decode routines for smarter linking
+*   2. Renamed lzsample.c sample.c to match my other samples
+*   3. Makefile now builds code as libraries for better LGPL compliance.
