I guess I was a bit too quick to throw away my regexp approach. apt_pkg
is pretty nice just that it does not yet support Python 2.4 on Sarge,
the documentation is practically non-existing and an attempt to read a
control file (not sure if that's even possible) in ipython gave me a
segmentation fault. Even the documentation in
/usr/share/doc/libapt-pkg-doc didn't help me much. May be my ignorance
of course.

Unless I understand what apt_pkg really is useful for I think I'll stick
to regular expressions. :(
