+# 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.
+#
+# It is probably wise to add these two files to .gitignore, so that you
+# don't accidentally commit either generated 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 at example])
+#
+# Then use the following lines in your Makefile.am, so that .version
+# will be present for dependencies, and so that .tarball-version will
+# exist in distribution tarballs.
+#
+# BUILT_SOURCES = $(top_srcdir)/.version
