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).
Cheers,
Fabio
