-# 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.
-#
-# 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 $@
-# dist-hook:
-# echo $(VERSION) > $(distdir)/.tarball-version
