Appended is a script that is a fairly straight-forward conversion of the
code in the above article to Python. Needs ctypes and comtypes.
Python 2.5 already includes ctypes; comtypes can be installed
with 'easy_install comtypes'.

GetModule("oleacc.dll")
# import the interface we need from the wrapper
