The Haskell Hackathon is an international, grassroots collaborative coding festival with a simple focus: build and improve Haskell libraries, tools, and infrastructure. Of course, we have fun doing it, too!

The 5th Haskell Hackathon was held from April 17 to 19, 2009, in the city of Utrecht in the Netherlands. The event was organized by members of the Department of Information and Computing Sciences at Utrecht University and by associates of Tupil.

The Dutch HUG was founded on the last day of the event.
