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 # svn_client - Use svn client i.s.o. ugly internal SVN file hack
33 # format - A strftime() formatted string to use as a template for
34 # the version string. The sequence "%#" will substitute
35 # the SVN revision number.
36 # pkg_enable - Enable or disable package versioning.
37 # pkg_format - Like "format", but used for the package version.
39 # If run with the "-p" or "--package-version" argument, the
40 # AC_INIT macro in configure.in and the VERSION macro in
41 # config.nmake will have the pkg_format template appended to the
42 # version number. svnversion.h will _not_ be generated if either
43 # argument is present.
45 # Default configuration:
49 # format: SVN %Y%m%d%H%M%S
53 # XXX - We're pretty dumb about the "%#" substitution, and about having
54 # spaces in the package format.
