Porting Extension Modules to Python 3
*************************************

We recommend the following resources for porting extension modules to Python 3:

* The `Migrating C extensions`_ chapter from
  *Supporting Python 3: An in-depth guide*, a book on moving from Python 2
  to Python 3 in general, guides the reader through porting an extension
  module.
* The `Porting guide`_ from the *py3c* project provides opinionated
  suggestions with supporting code.
* The `Cython`_ and `CFFI`_ libraries offer abstractions over
  Python's C API.
  Extensions generally need to be re-written to use one of them,
  but the library then handles differences between various Python
  versions and implementations.
