gtk-doc goes python

[Stefan Sauer <ensonic hora-obscura de>]

Hi,

as a heads up - Jussi Pakkanen and I are rewriting gtkdoc to python. The
shell scripts are already gone (so running gtkdoc won't need a shell
anymore). At the same time we're modernizing it a bit and adding more
and proper tests. This is all very much work in progress though. If we
break something, please ping us in irc (#gtkdoc) or file a bug. Also
help is very welcome.

Stefan
