This is GlomeTrace, a ray tracing library. Originally, it was part of Glome-hs, my haskell ray tracer. I decided to pull out the code to trace rays against objects and distribute it as a stand-alone library so that other projects can use it.
A good source of documentation is the Haskell wiki. In particular, take a look at the tutorial I wrote for Glome-hs. A few things have changed, but most of the descriptions there are still mostly valid.
If you're installing from a tarball, the usual commands will suffice:
runhaskell Setup configure; runhaskell Setup build; runhaskell Setup install
Note that GlomeTrace requires GlomeVec, a vector math library.
