4.3 Notices in `configure'
The following macros manage version numbers for `configure' scripts.
Using them is optional.
-- Macro: AC_COPYRIGHT (COPYRIGHT-NOTICE)
State that, in addition to the Free Software Foundation's
copyright on the Autoconf macros, parts of your `configure' are
covered by the COPYRIGHT-NOTICE.
The COPYRIGHT-NOTICE shows up in both the head of `configure' and
in `configure --version'.
-- Macro: AC_REVISION (REVISION-INFO)
Copy revision stamp REVISION-INFO into the `configure' script,
with any dollar signs or double-quotes removed. This macro lets
you put a revision stamp from `configure.ac' into `configure'
without RCS or CVS changing it when you check in `configure'.
That way, you can determine easily which revision of
`configure.ac' a particular `configure' corresponds to.
For example, this line in `configure.ac':
AC_REVISION([$Revision: 1.30 $])
produces this in `configure':
# From configure.ac Revision: 1.30
