mpi4py 1.3.1

on Python PyPI

Regenerate C wrappers with Cython 0.19.1 to support Python 3.3.

Install *.pxd files in <site-packages>/mpi4py to ease the
support for Cython's cimport statement in code requiring to
access mpi4py internals.

As a side-effect of using Cython 0.19.1, ancient Python 2.3 is no
longer supported. If you really need it, you can install an older
Cython and run python setup.py build_src --force.
