Indeed! :)

I *love* hearing that it's being used. I'm just throwing this out
there... if ArchHaskell goes the way of the dodo I'd be more than happy
to continue working on cblrepo, and make it more suitable for your use
case.

That is true, I think there is a document somewhere describing what kind
of edits to metadata that is allowed via Hackage.

Since cblrepo keeps track of ranges of dependencies itself I've found
cases where it's really useful to pull xrevs into its database
(cblrepo.db). However, this doesn't really mean that one has to release
a new package on a new xrev (essentially tell pacman about the change to
dependencies). If one is willing to move this knowledge from cblrepo to
pacman in some other way (I'm guessing you're doing it manually, Felix)
then that's fine. I'm just too lazy to do that ;)
