Chris Angelico -- http://mail.python.org/mailman/listinfo/python-list There are some wrapping libraries that may help in wrapping C/C++ for Python... Take a look at Boost::Python, Swig, Sip and Cython (personally, I like Boost::Python, but the generated code can be a bit bloated -- but not a problem unless it's a really huge library -- Cython seems nice too, but I've only made few things with it, so, I can't comment much).
