25 # usage: ./make-version.pl [-p] [--package-version]
27 # If "version.conf" is present, it is parsed for configuration values.
28 # Possible values are:
30 # enable - Enable or disable versioning. Zero (0) disables, nonzero
32 # format - A strftime() formatted string to use as a template for
33 # the version string. The sequence "%#" will substitute
34 # the SVN revision number.
35 # pkg_format - Like "format", but used for the package version.
37 # If run with the "-p" or "--package-version" argument, the
38 # AM_INIT_AUTOMAKE macro in configure.in and the VERSION macro in
39 # config.nmake will have the pkg_format template appended to the
40 # version number. svnversion.h will _not_ be generated if either
41 # argument is present.
43 # Default configuration:
46 # format: SVN %Y%m%d%H%M%S
50 # XXX - We're pretty dumb about the "%#" substitution, and about having
51 # spaces in the package format.
