[Haskell-beginners] gtk2hs website

Hi everybody, I was starting to learn how to use gtk2hs. Unfortunately, the web site for it has suddenly disappeared. It used to be at "http://www.haskell.org/gtk2hs/". The information on the Haskell page "http://www.haskell.org/haskellwiki/Gtk2Hs" is not enough to understand how the library works. Does anybody know how I can access the old site? Thanks, Venanzio
