%description
The Cython language allows for writing C extensions for the Python
language. Cython is a source code translator based on Pyrex, but
supports more cutting edge functionality and optimizations.

The Cython language is very close to the Python language (and most Python
code is also valid Cython code), 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.
