I found the documentation on setting up an include file for urls a little confusing for a new django user: http://docs.djangoproject.com/en/1.0/intro/tutorial03/#intro-tutorial03
The part I got tripped up on was code sample:
(r'polls/', include('mysite.polls.urls')),
It was not apparent to me until after I read the docs here http://docs.djangoproject.com/en/dev/topics/http/urls/ that the include was supposed to be part of the urlpatterns.
I mistakenly just added the include statement above and was greated with the error message, "'module' object has no attribute 'urlpatterns'". It could be just me, but I would recommend either expanding the code sample to include the urlpatterns or add a note about this potential error message.
