-Natural Sorting with ``cmp`` (Python 2 only)
---------------------------------------------
-
-.. note::
-    This is a Python2-only feature! The :func:`natcmp` function is not
-    exposed on Python3. Because this documentation is built with
-    Python3, you will not find :func:`natcmp` in the API.

-If you are using a legacy codebase that requires you to use :func:`cmp` instead
-of a key-function, you can use :func:`~natcmp`.

-:func:`natcmp` also accepts an ``alg`` argument so you can customize your
