  you can also allow users of the admin app to see a short description of the
  field type via the :doc:`django.contrib.admindocs
  </ref/contrib/admin/admindocs>` application. To do this simply provide
  descriptive text in a ``description`` class attribute of your custom field. In
  the above example, the type description displayed by the ``admindocs``
  application for a ``HandField`` will be 'A hand of cards (bridge style)'.

some other way, of course, but this gives you a way to tell Django to get out of
the way.
