Module documentation for 0.2.3.5

This library makes it easy to implement monads with tricky control flow.

This is useful for: writing web applications in a sequential style, programming games with a uniform interface for human and AI players and easy replay capababilities, implementing fast parser monads, designing monadic DSLs, etc.

See the project homepage http://wiki.haskell.org/Operational for a more detailed introduction and features.
