# 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.
