Welcome to Cython!  

==================

Cython 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.
