224 The Cython language makes writing C extensions for the Python language as
225 easy as Python itself. Cython is a source code translator based on the
226 well-known Pyrex_, but supports more cutting edge functionality and
229 The Cython language is very close to the Python language (and most Python
230 code is also valid Cython code), but Cython additionally supports calling C
231 functions and declaring C types on variables and class attributes. This
232 allows the compiler to generate very efficient C code from Cython code.
234 This makes Cython the ideal language for writing glue code for external C
235 libraries, and for fast C modules that speed up the execution of Python
