Python 3

Porting to Python 3 can be painful, but reading around the subject shows us that people have had success porting their code to 3.x by simply compiling their module with Cython instead of actually porting their code! With Cython, you can specify the output to conform to the Python 3 API via the following:

$ cython -3 <options>

This will make sure you are outputting Python 3 stuff instead of the default argument of -2, which generates for the 2.x standard.
