Module documentation for 0.7.8

This is an implementation of Cloud Haskell, as described in Towards Haskell in the Cloud by Jeff Epstein, Andrew Black, and Simon Peyton Jones (https://simon.peytonjones.org/haskell-cloud/), although some of the details are different. The precise message passing semantics are based on A unified semantics for future Erlang by Hans Svensson, Lars-Åke Fredlund and Clara Benac Earle.

You will probably also want to install a Cloud Haskell backend such as distributed-process-simplelocalnet.
