+An example dictionary-based configuration
+-----------------------------------------
+
+Below is an example of a logging configuration dictionary - it's taken from
+the `documentation on the Django project <https://docs.djangoproject.com/en/1.3/topics/logging/#configuring-logging>`_.
+This dictionary is passed to :func:`~logging.config.dictConfig` to put the configuration into effect::
