I haven't had much time to work on gitit + filestore lately, and I'll
have even less in the future.  I'd rather focus my programming time on
pandoc.  So I'd be game if someone wanted to take the project in a new

Looks as if there are already Haskell bindings to libgit2:
A first step might be rewriting filestore to use libgit and libdarcs
instead of shelling out to the programs.

It also might be nice to create a filestore instance that uses a
persistent in-memory datastore like acid-state; this would be very fast,
and appropriate for a wiki (like hawiki) with mostly textual content.

I would also not object to a rewrite using Yesod -- the type-safe URLs
and the support for subsites would both be really useful in gitit.
