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’:

          #!/bin/sh
          # From configure.ac Revision: 1.30
