# This script extracts the components from an OCaml version number
# and provides them as C defines:
# OCAML_VERSION_MAJOR: the major version number
# OCAML_VERSION_MAJOR: the minor version number
# OCAML_VERSION_PATCHLEVEL: the patchlevel number if present, or 0 if absent
# OCAML_VERSION_ADDITIONAL: this is defined only if the additional-info
# field is present, and is a string that contains that field.
# Note that additional-info is always absent in officially-released
# versions of OCaml.
# usage:
# make-version-header.sh [version-file]
# The argument is the VERSION file from the OCaml sources.
# If the argument is not given, the version number from "ocamlc -v" will
# be used.
