Statechart [1] is a program that compiles Rhapsody [2] statechart diagrams [3] into C. Rhapsody is a UML tool from IBM intended for embedded systems development. If you use Rhapsody, and its code generator makes your eyes bleed, statechart may provide some relief. -Tom [1] http://hackage.haskell.org/package/statechart [2] http://www-01.ibm.com/software/rational/products/rhapsody/developer/ [3] http://en.wikipedia.org/wiki/State_diagram#Harel_statechart
