True enough, but...

One could coax SWIG to also produce the .pyx files to wrap.

It begs the question, why not just use SWIG in that case.

The answer probably is that if all you want is just wrapping,
then use SWIG.  But if you want access to the types from Pyrex
then it may make sense.

So SWIG becomes the express train for exposing C code to Pyrex
(and possibly Python as well).
