HList (and OOHaskell, for that matter) are now hosted on community.haskell.org, in the directories /srv/code/HList /srv/code/OOHaskell The repositories are also available at these URLs: http://code.haskell.org/HList/ http://code.haskell.org/OOHaskell/ Many thanks to Ian Lynagh for moving the repositories. Ian has kindly set up the redirection so that the old, used in many places URL http://darcs.haskell.org/HList/ still works. It now redirects to code.haskell.org.
