 Homepage:       http://rochel.info/#graph-rewriting
 Stability:      beta
 Build-Type:     Simple
-Synopsis:       Two implementations of the SKI combinators as interactive graph rewrite systems
-Description:    This package serves as an example for how to use the graph-rewriting, graph-rewriting-layout, and graph-rewriting-gl packages to create a graph rewriting system with an interactive, graphical front-end. The SKI combinator calculus is implemented once as an interaction net with combinators that accumulate their arguments, and once in a more direct manner. The sources (of the interaction net implementation) are well documented and serve as a tutorial for implementing your own rewrite system. Start reading in INet/Graph.hs. To run the program run either the "ski-inet" or the "ski-direct" with one of the files from the "examples" directory as an argument. For usage of the GUI see "GraphRewriting.GL.UI".
