"The ForSyDe (Formal System Design) methodology has been developed with the objective to move system design to a higher level of abstraction and to bridge the abstraction gap by transformational design refinement. This library provides ForSyDe's implementation as a Haskell-embedded Domain Specific Language (DSL). For more information, please see ForSyDe's website: http://www.ict.kth.se/forsyde/."

In addition to compatibility with base 4 and GHC 6.10.x, the new version provides more freedom for declaration of process functions (e.g., support for when and let blocks).
