From http://pypi.python.org/pypi/guppy/0.1.8:

Guppy-PE is a library and programming environment for Python, currently providing in particular the Heapy subsystem, which supports object and heap memory sizing, profiling and debugging. It also includes a prototypical specification language, the Guppy Specificaion Language (GSL), which can be used to formally specify aspects of Python programs and generate tests and documentation from a common source.

This should help us track down some interesting issues :)

Cheers,

Michael
