You're right. Settings are not even necessary in my example, as we should be fine with defaults in most cases. The only lines you really need are these four:
from django.conf import settings
settings.configure(ROOT_URLCONF='polls')
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
You lose some of the Django niceties (like being able to provide your own custom settings on the command-line) but flask doesn't have them anyway.
