-Distributing Extensions compiled with Cython
---------------------------------------------
-
-``setuptools`` will detect at build time whether Cython is installed or not.
-If Cython is not found ``setuptools`` will ignore pyx files.
-
-To ensure Cython is available, include Cython in the build-requires section
-of your pyproject.toml::
-
-    [build-system]
-    requires=[..., "cython"]
-
-Built with pip 10 or later, that declaration is sufficient to include Cython
-in the build. For broader compatibility, declare the dependency in your
-setup-requires of setup.cfg::
-
-    [options]
-    setup_requires =
-        ...
-        cython
-
-As long as Cython is present in the build environment, ``setuptools`` includes
-transparent support for building Cython extensions, as
-long as extensions are defined using ``setuptools.Extension``.
-
-If you follow these rules, you can safely list ``.pyx`` files as the source
-of your ``Extension`` objects in the setup script.  If it is, then ``setuptools``
-will use it.
-
-Of course, for this to work, your source distributions must include the C
-code generated by Cython, as well as your original ``.pyx`` files.  This means
-that you will probably want to include current ``.c`` files in your revision
-control system, rebuilding them whenever you check changes in for the ``.pyx``
-source files.  This will ensure that people tracking your project in a revision
-control system will be able to build it even if they don't have Cython
-installed, and that your source releases will be similarly usable with or
-without Cython.
