Hi Michael,
I'm happy to see that you're being so thorough in the development of those
features libqapt (especially with the addition of unit tests, really
appreciated). I'm not the most adequate person to approve the patch, but as
a muon developer I'd really like to see these changes in.

By the way, why does it have a directory called "t"?
