Welcome to Cython!
=================

Cython (http://cython.org) is a language that makes writing C extensions for
the Python language as easy as Python itself.  Cython is based on the
well-known Pyrex, but supports more cutting edge functionality and
optimizations.

The Cython language is very close to the Python language, but Cython
additionally supports calling C functions and declaring C types on variables
and class attributes.  This allows the compiler to generate very efficient C
code from Cython code.

This makes Cython the ideal language for wrapping external C libraries, and
for fast C modules that speed up the execution of Python code.
