configureThe following macros manage version numbers for configure
scripts. Using them is optional.
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’.
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
