This project is a set of tut documents that you can compile into final documentation by saying tut from the sbt prompt. The output can be found under target/scala-N.NN/tut/.
For now the doc is copied into a parallel checkout of tpolecat.github.io via the hacked-up ctut command, and from there it gets pushed up to the internets where it gets the Jekyll treatment. The end result is nice but the process is a bit crufty.
