The Haskell language was started by a group of researchers interested in an open source lazy, purely functional language. Haskell.org is the social and developmental center for this continuing project. Haskell.org hosts websites, wikis, source code and research papers, all of these focussed on exploring and extending the Haskell language.
This hosting site is only for sample code provided to Google for the Summer-of-Code programme 2007. Please check haskell.org for the real on-going project repositories.
