+# If "version.conf" is present, it is parsed for configuration values.
+# Possible values are:
+#
+# enable - Enable or disable versioning. Zero (0) disables, nonzero
+# enables.
+# svn_client - Use svn client i.s.o. ugly internal SVN file hack
+# format - A strftime() formatted string to use as a template for
+# the version string. The sequence "%#" will substitute
+# the SVN revision number.
+# pkg_enable - Enable or disable package versioning.
+# pkg_format - Like "format", but used for the package version.
+#
+# If run with the "-p" or "--package-version" argument, the
+# AM_INIT_AUTOMAKE macro in configure.in and the VERSION macro in
+# config.nmake will have the pkg_format template appended to the
+# version number. svnversion.h will _not_ be generated if either
+# argument is present.
+#
+# Default configuration:
+#
+# enable: 1
+# svn_client: 0 <- This needs to change in order to support SVN 1.4
+# format: SVN %Y%m%d%H%M%S
+# pkg_enable: 1
+# pkg_format: -SVN-%#
+# am_init: 0
+
+# XXX - We're pretty dumb about the "%#" substitution, and about having
+# spaces in the package format.
