  26 #
  27 # If "version.conf" is present, it is parsed for configuration values.
  28 # Possible values are:
  29 #
  30 #   enable     - Enable or disable versioning.  Zero (0) disables, nonzero
  31 #                enables.
  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 local package versioning.
  37 #   pkg_format - Like "format", but used for the local package version.
  38 #
  39 # If run with the "-r" or "--set-release" argument the AC_INIT macro in
  40 # configure.in and the VERSION macro in config.nmake will have the
  41 # pkg_format template appended to the version number. svnversion.h will
  42 # _not_ be generated if either argument is present.
  43 #
  44 # Default configuration:
  45 #
  46 # enable: 1
  47 # svn_client: 1
  48 # format: SVN %Y%m%d%H%M%S
  49 # pkg_enable: 1
