       pristine-tar - regenerate pristine tarballs
       pristine-gz - regenerate pristine gz files
       pristine-bz2 - regenerate pristine bz2 files

What they do is to store the files from the files in one branch. Then
they generate a tar/gz/bz2 from that and store the delta to the
prisine file in another branch. With both together the pristine file
can be recreated.
