[python-win32] Fwd: Building win32 extensions to Python

[Kevin Horn]

Another option might be to wrap your C code using the ctypes module (
http://starship.python.net/crew/theller/ctypes/).  This might be especially
attractive if this code is mostly for demo purposes (at least for demo
purposes on win32).  Ctypes basically allows you to call C code from python,
but rather than handling the data type translations in C (like in a "normal"
extension), you handle the translations in Python.

For C++ code you might check out boost.python.  I haven't used it but I've
heard good things.
