20 | # This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/. | ||
21 | # It may be run two ways: | ||
22 | # - from a git repository in which the "git describe" command below | ||
23 | # produces useful output (thus requiring at least one signed tag) | ||
24 | # - from a non-git-repo directory containing a .tarball-version file, which | ||
25 | # presumes this script is invoked like "./git-version-gen .tarball-version". | ||
26 | |||
27 | # In order to use intra-version strings in your project, you will need two | ||
28 | # separate generated version string files: | ||
29 | # | ||
30 | # .tarball-version - present only in a distribution tarball, and not in | ||
31 | # a checked-out repository. Created with contents that were learned at | ||
32 | # the last time autoconf was run, and used by git-version-gen. Must not | ||
33 | # be present in either $(srcdir) or $(builddir) for git-version-gen to | ||
34 | # give accurate answers during normal development with a checked out tree, | ||
35 | # but must be present in a tarball when there is no version control system. | ||
36 | # Therefore, it cannot be used in any dependencies. GNUmakefile has | ||
37 | # hooks to force a reconfigure at distribution time to get the value | ||
38 | # correct, without penalizing normal development with extra reconfigures. | ||
39 | # | ||
40 | # .version - present in a checked-out repository and in a distribution | ||
41 | # tarball. Usable in dependencies, particularly for files that don't | ||
42 | # want to depend on config.h but do want to track version changes. | ||
43 | # Delete this file prior to any autoconf run where you want to rebuild | ||
44 | # files to pick up a version string change; and leave it stale to | ||
45 | # minimize rebuild time after unrelated changes to configure sources. | ||
46 | # | ||
47 | # As with any generated file in a VC'd directory, you should add | ||
48 | # /.version to .gitignore, so that you don't accidentally commit it. | ||
49 | # .tarball-version is never generated in a VC'd directory, so needn't | ||
50 | # be listed there. | ||
51 | # | ||
52 | # Use the following line in your configure.ac, so that $(VERSION) will | ||
53 | # automatically be up-to-date each time configure is run (and note that | ||
54 | # since configure.ac no longer includes a version string, Makefile rules | ||
55 | # should not depend on configure.ac for version updates). | ||
56 | # | ||
57 | # AC_INIT([GNU project], | ||
58 | # m4_esyscmd([build-aux/git-version-gen .tarball-version]), | ||
59 | # [bug-project@example]) | ||
60 | # | ||
61 | # Then use the following lines in your Makefile.am, so that .version | ||
62 | # will be present for dependencies, and so that .version and | ||
63 | # .tarball-version will exist in distribution tarballs. | ||
