	+# This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/.
	+# It may be run two ways:
	+# - from a git repository in which the "git describe" command below
	+# produces useful output (thus requiring at least one signed tag)
	+# - from a non-git-repo directory containing a .tarball-version file, which
	+# presumes this script is invoked like "./git-version-gen .tarball-version".
	+
	+# In order to use intra-version strings in your project, you will need two
	+# separate generated version string files:
	+#
	+# .tarball-version - present only in a distribution tarball, and not in
	+# a checked-out repository. Created with contents that were learned at
	+# the last time autoconf was run, and used by git-version-gen. Must not
	+# be present in either $(srcdir) or $(builddir) for git-version-gen to
	+# give accurate answers during normal development with a checked out tree,
	+# but must be present in a tarball when there is no version control system.
	+# Therefore, it cannot be used in any dependencies. GNUmakefile has
	+# hooks to force a reconfigure at distribution time to get the value
	+# correct, without penalizing normal development with extra reconfigures.
	+#
	+# .version - present in a checked-out repository and in a distribution
	+# tarball. Usable in dependencies, particularly for files that don't
	+# want to depend on config.h but do want to track version changes.
	+# Delete this file prior to any autoconf run where you want to rebuild
	+# files to pick up a version string change; and leave it stale to
	+# minimize rebuild time after unrelated changes to configure sources.
	+#
	+# As with any generated file in a VC'd directory, you should add
	+# /.version to .gitignore, so that you don't accidentally commit it.
	+# .tarball-version is never generated in a VC'd directory, so needn't
	+# be listed there.
	+#
	+# In order to use git archive versions another two files has to be presented:
	+#
	+# .gitarchive-version - present in checked-out repository and git
	+# archive tarball, but not in the distribution tarball. Used as a last
	+# option for version. File must contain special string $Format:%d$,
	+# which is substitued by git on archive operation.
	+#
	+# .gitattributes - present in checked-out repository and git archive
	+# tarball, but not in the distribution tarball. Must set export-subst
	+# attribute for .gitarchive-version file.
	+#
	+# Use the following line in your configure.ac, so that $(VERSION) will
	+# automatically be up-to-date each time configure is run (and note that
	+# since configure.ac no longer includes a version string, Makefile rules
	+# should not depend on configure.ac for version updates).
	+#
	+# AC_INIT([GNU project],
	+# m4_esyscmd([build-aux/git-version-gen .tarball-version]),
	+# [bug-project@example])
	+#
	+# Then use the following lines in your Makefile.am, so that .version
	+# will be present for dependencies, and so that .version and
	+# .tarball-version will exist in distribution tarballs.
	+#
	+# EXTRA_DIST = $(top_srcdir)/.version
	+# BUILT_SOURCES = $(top_srcdir)/.version
	+# $(top_srcdir)/.version:
	+# echo $(VERSION) > $@-t && mv $@-t $@
