This code has been tested with Coq 8.4pl1 and 8.4pl2.

To make, simply type "make". (The standard UNIX make tool is expected.)
You will see several warnings that Coq "could not define graph(s)."
These are normal and expected.  They indicate that Coq could not
automatically generate certain induction schema.
