# If "version.conf" is present, it is parsed for configuration values.
# Possible values are:
#
-# enable - Enable or disable versioning. Zero (0) disables, nonzero
-# enables.
-# format - A strftime() formatted string to use as a template for the
-# version string.
+# enable - Enable or disable versioning. Zero (0) disables, nonzero
+# enables.
+# format - A strftime() formatted string to use as a template for
+# the version string. The sequence "%#" will substitute
+# the SVN revision number.
+# 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
-# format: CVS %Y%m%d%H%M%S
+# format: SVN %Y%m%d%H%M%S
+# pkg_format: -SVN-%#
+# am_init: 0
+
+# XXX - We're pretty dumb about the "%#" substitution, and about having
+# spaces in the package format.
