— 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
