This describes the Python interface to PerfTools and Graphviz.  It is
minimal as development is on-going.

1) Build Graphviz interface

cd /path/to/python/graphviz/graph
make
(fix problems)
make
(rinse, repeat).

It needs SWIG 1.3 (www.swig.org).

2) Set the environment variables:

export PYTHONPATH=/path/to/python

3) Wait.
