 The Cython language makes writing C extensions for the Python language
 as easy as Python itself. Cython is a source code translator based on
 the well-known 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.
 
 This makes Cython the ideal language for writing glue code for external
 C libraries, and for fast C modules that speed up the execution of
 Python code.
