Hi, I got told about this site by a person: http://mathematik.htwm.de/cgi-bin/dwww?type=file&location=/usr/share/doc/hat/html/index.html They found this with the google search: http://www.google.com/search?q=hat-stack%20haskell They were deeply confused, because all the documentation links were broken, so they didn't have a clue how to generate a .hat file. It would be best if this mirror site was removed, turned into a redirect to the main Haskell site, or fixed to be a complete mirror. Thanks Neil
