Swig is for wrapping existing C libraries with as little fuss as possible. The interfaces 
it generates can be customized if you are willing to spend the time studying the 
documentation.

Pyrex is for writing extension modules from scratch, though naturally it can also be 
used to create wrappers. But I would try writing the module in pure Python if 
possible and only make it an extension module if performation or memory is an 
issue.
