[Pyrex] How to prove better Pyrex performance?

[Daniele Pianu]

I've to write a Python script that shows the better Pyrex performance
against Swig performance. I've to highlight the overhead due to
different layers of Swig wrappers, instead of Pyrex wrappers which
have only one layer made up of Python/C Api calls. I think I need to
write something like a wrapper of a C library that does mathematical
stuff. Could it be a good example? Every advice is welcome.
