        commit-patch relies on several programs to get the job done:
 
           perl       - <http://www.perl.org>
-          IPC::Run   - <http://search.cpan.org/dist/IPC-Run/>
           patch      - <http://www.gnu.org/software/patch/>
           interdiff  - <http://cyberelk.net/tim/software/patchutils/>
           cp         - Ideally installed on your system already. :-)
