+# 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@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 |
