 ----------------------------------------------
 
 There are a number of alternatives to writing your own C extensions, depending

-`Cython <https://cython.org>`_ and its relative `Pyrex
-<https://www.csse.canterbury.ac.nz/greg.ewing/python/Pyrex/>`_ are compilers
-that accept a slightly modified form of Python and generate the corresponding
-C code.  Cython and Pyrex make it possible to write an extension without having
-to learn Python's C API.

-If you need to interface to some C or C++ library for which no Python extension
-currently exists, you can try wrapping the library's data types and functions
-with a tool such as `SWIG <https://www.swig.org>`_.  `SIP
