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.
38 # is_release - Specifies that we're building from a release tarball;
39 # svnversion.h is not updated. This should be added only
40 # to the *released* version.conf, not the one used to build
41 # the release (IOW it should be added by automake's dist-hook).
43 # If run with the "-p" or "--package-version" argument, the
44 # AC_INIT macro in configure.in and the VERSION macro in
45 # config.nmake will have the pkg_format template appended to the
46 # version number. svnversion.h will _not_ be generated if either
47 # argument is present (it will also not be generated if 'is_release' is set
50 # Default configuration:
54 # format: SVN %Y%m%d%H%M%S
