13 # If "version.conf" is present, it is parsed for configuration values.
14 # Possible values are:
15 #
16 #   enable       - Enable or disable versioning.  Zero (0) disables, nonzero
17 #                  enables.
18 #   svn_client   - Use svn client i.s.o. ugly internal SVN file hack
19 #   tortoise_svn - Use TortoiseSVN client instead of ugly internal SVN
20 #                  file hack
21 #   format       - A strftime() formatted string to use as a template for
22 #                  the version string. The sequence "%#" will substitute
23 #                  the number of commits for Git or the revision number
24 #                  for SVN.
25 #   pkg_enable   - Enable or disable local package versioning.
26 #   pkg_format   - Like "format", but used for the local package version.
27 #
28 # If run with the "-r" or "--set-release" argument the AC_INIT macro in
29 # configure.ac and the VERSION macro in CMakeLists.txt will have the
30 # pkg_format template appended to the version number. version.h will
31 # _not_ be generated if either argument is present.
32 #
33 # Default configuration:
34 #
35 # enable: 1
36 # git_client: 0
37 # svn_client: 0
38 # git_svn: 0
39 # tortoise_svn: 0

41 # pkg_enable: 1
42 # pkg_format: -%#
43
44 # XXX - We're pretty dumb about the "%#" substitution, and about having
45 # spaces in the package format.
