    Configures Django by:

    * Loading the settings.

    * Setting up logging.

    * If ``set_script`` is True, setting the URL resolver script prefix to

      :setting:`FORCE_SCRIPT_NAME` if defined, or ``/`` otherwise.

    * Initializing the application registry.

        The ability to set the URL resolver script prefix is new.

    This function is called automatically:

    * When running an HTTP server via Django's WSGI support.

If not ``None``, this will be used as the value of the ``SCRIPT_NAME``

environment variable in any HTTP request. This setting can be used to override

the server-provided value of ``SCRIPT_NAME``, which may be a rewritten version

of the preferred value or not supplied at all.

of the preferred value or not supplied at all. It is also used by

:func:`django.setup()` to set the URL resolver script prefix outside of the

request/response cycle (e.g. in management commands and standalone scripts) to

generate correct URLs when ``SCRIPT_NAME`` is not ``/``.

.. versionchanged:: 1.10

    The setting's use in :func:`django.setup()` was added.

^^^^

* ...

* An addition in :func:`django.setup()` allows URL resolving that happens

  outside of the request/response cycle (e.g. in management commands and

  standalone scripts) to take :setting:`FORCE_SCRIPT_NAME` into account when it

  is set.
