Document how to use configuration from django settings

I haven't worked with flower in some time and thought that I remember it used to be configured from the celery configuration file. Is there any baked in way to pull the configuration variables from a Django settings file?

For example, Celery is like:

from celery import Celery
app = Celery('project')
app.config_from_object('django.conf:settings', namespace='CELERY')

Is it as simple as prefixing the options with FLOWER_ and adding them to the celery config?

It isn't very clear from reading the docs unless the flowerconfig.py file is the only way to do it?
