[arch-haskell] Distribution.ArchLinux maintainer search for the AUR

[Tasha Buckley]

Greetings,

The JSON AUR interface now has an msearch method in its API to allow
finding all packages by a certain maintainer.

So now it's possible to do:
http://aur.archlinux.org/rpc.php?type=msearch&arg=arch-haskell to get
all the packages maintained by the arch-haskell devs.

The change required in Distribution.ArchLinux is trivial, but I would
be willing to provide a darcs patch if it's somehow needed.
