Add ability to add "copyright", "authors" & "exit status" to man page

[BrunnerLivio]

I would like to have the sections "copyright" "authors" & "exit status", like in
man man :

EXIT-STATUS
       0      erfolgreiche Programmausführung

       1      Fehler beim Aufruf, in der Syntax oder in der Konfigurationsdatei

       2      betriebsbedingter Fehler

       3      Ein Kind-Prozess gab einen von Null verschiedenen EXIT-Status zurück.

       16     Mindestens eine Seite/Datei oder ein Schlüsselwort gibt es nicht oder es wurden keine Treffer dafür gefunden.

man chmod :

I'm not quiet sure yet on how to inject those data into click-man.
Via setuptools option would be possible but ugly because you'll get /usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: FOO

Via command line option to the man_pages command is quiet verbose on the other side ...

Maybe a separate configuration file? Like .clickmanrc ?
