Get working under Windows with http://cheeseshop.python.org/pypi/PyCS…

…C/0.3 (with Python 2.5 for Windows)

Note: you additionally need pycrypto, the source of which you'll get from http://cheeseshop.python.org/pypi/pycrypto/2.0.1
  Compilation of pycrypto can work with cygwin in two steps: python setup.py build -c mingw32 and python setup.py install --skip-build
