1Welcome to Cython!
2=================
3
4Cython (http://cython.org) is a language that makes writing C extensions for
5the Python language as easy as Python itself. Cython is based on the
6well-known Pyrex, but supports more cutting edge functionality and
7optimizations.
8
9The Cython language is very close to the Python language, but Cython
10additionally supports calling C functions and declaring C types on variables
11and class attributes. This allows the compiler to generate very efficient C
12code from Cython code.
13
14This makes Cython the ideal language for wrapping external C libraries, and
15for fast C modules that speed up the execution of Python code.
