That approach is probably optimal, but not everyone will use cblrepo. As it's
easy to add, it is better to include the necessary information for
"traditional" Pacman packaging. That way everyone is happy. The Haskell
guidelines can always be updated to strongly recommend using cblrepo (if they
don't already).

You can just check "pacman -Si ghc" or "pacman -Qi ghc" to see what is
provided. You could also use e.g. pyalpm to write a very simple script to do it
as well, or even write a Bash script to parse the pacman database files.

I don't mean that those approaches would be better. I only mention them as
alternatives to checking ABS.



Anyway, Magnus has agreed to re-insert the provides array, so this is once
again just a matter of user choice, which should make everyone happy. ;)
