URI parsing module, written in Haskell, with unit tests. Written in 2010 as part of a larger project I started working on on the side. When I discovered the existing uri project on Hackage, I sent this to the maintainer of that, and he used parts of this, however I think there are some good bits in here that didn't make it into uri. I shelved my larger project when we had a baby in 2010, but am making this available in case somebody finds it useful.
