So far, I got by with the small System.Cmd module from the process
library which is included in the Haskell Platform.
If you need to capture stdin and stdout , you may want to look at
System.Process from the same library instead. Other libraries are
available on hackage, too, like John Goerzen's (of RWH fame) package HSH :

This paper was very interesting to me. Does anyone know if the full source code
for the Haskell prototype is available somewhere?

Chapter 8 of Paul Hudak's School of Expression contains a version of
the "region algebra", there's also an ML version by Samuel Kamin where
the region combinators generate C++ code:
