The unified Haskell network, web and wiki stack is now in AUR:

happs-server, the standalone web appliance kit

haskell-salvia, the other standalone web appliance kit for Haskell

filestore, the unified darcs/git file versioning API

orchid, the Haskell wiki library

gitit, the mediawiki-alike standalone wiki system using markdown

and related libs. So you should be able to run either wiki system (gitit or orchid) out of the box now. gitit makes a good case for an automatic dependency resolver, too…

The new unified filestore API project was announced earlier today.
