"""Python.Interpreter COM Server
This module implements a very very simple COM server which
exposes the Python interpreter.
This is designed more as a demonstration than a full blown COM server.
General functionality and Error handling are both limited.
To use this object, ensure it is registered by running this module
from Python.exe. Then, from Visual Basic, use "CreateObject('Python.Interpreter')",
and call its methods!
