1 4.3 Notices in `configure'
1 ==========================
1 
1 The following macros manage version numbers for `configure' scripts.
1 Using them is optional.
1 
1  -- Macro: AC_COPYRIGHT (COPYRIGHT-NOTICE)
1      State that, in addition to the Free Software Foundation's
1      copyright on the Autoconf macros, parts of your `configure' are
1      covered by the COPYRIGHT-NOTICE.
1 
1      The COPYRIGHT-NOTICE shows up in both the head of `configure' and
1      in `configure --version'.
1 
1  -- Macro: AC_REVISION (REVISION-INFO)
1      Copy revision stamp REVISION-INFO into the `configure' script,
1      with any dollar signs or double-quotes removed.  This macro lets
1      you put a revision stamp from `configure.ac' into `configure'
1      without RCS or CVS changing it when you check in `configure'.
1      That way, you can determine easily which revision of
1      `configure.ac' a particular `configure' corresponds to.
1 
1      For example, this line in `configure.ac':
1 
1           AC_REVISION([$Revision: 1.30 $])
1 
1      produces this in `configure':
1 
1           #!/bin/sh
1           # From configure.ac Revision: 1.30
