25 # If "version.conf" is present, it is parsed for configuration values.
26 # Possible values are:
27 #
28 #   enable     - Enable or disable versioning.  Zero (0) disables, nonzero
29 #                enables.
30 #   svn_client - Use svn client i.s.o. ugly internal SVN file hack
31 #   format     - A strftime() formatted string to use as a template for
32 #                the version string. The sequence "%#" will substitute
33 #                the SVN revision number.
34 #   pkg_enable - Enable or disable local package versioning.
35 #   pkg_format - Like "format", but used for the local package version.
36 #
37 # If run with the "-r" or "--set-release" argument the AC_INIT macro in
38 # configure.ac and the VERSION macro in config.nmake will have the
39 # pkg_format template appended to the version number. version.h will
40 # _not_ be generated if either argument is present.
41 #
42 # Default configuration:
43 #
44 # enable: 1
45 # svn_client: 1
46 # format: SVN %Y%m%d%H%M%S
47 # pkg_enable: 1
