I just posted code for the Haskell Library Infrastructure Project here.
I'm using Arch for version control, and so far I'm really pleased with it.
In brief, the Library Infrastructure Project is an effort to provide a framework for developers to more effectively contribute their software to the Haskell community. I'm hoping to not have to implement this entire proposal myself, and I'm very flexible about implementation details. I've made some concrete progress, and I just mirrored my code repository on my web site, so now is the time to get involved!
Anyone interested should follow the discussion on the Haskell libraries mailing list.
