GitHub is a terrible upstream
(Let's try this again, but with less fail!)
Getting source tarballs from github is a nightmare. See
http://lists.fedoraproject.org/pipermail/devel/2011-February/148676.html
The debian tool doesn't help very much because one still needs revision
garbage in the specfile. Is there any more recent ways to mitigate this?
Perhaps we could "lobby" github to change their ways, at least partially?
