10303	Contradiction in updating-multiple-objects-at-once doc?	gluckj	nobody	"Hi, 

I was reading [http://docs.djangoproject.com/en/dev/topics/db/queries/#updating-multiple-objects-at-once] just now.

It first says: 
'''""You can only set non-relation fields and ForeignKey fields using this method, and the value you set the field to must be a hard-coded Python value (i.e., you can't set a field to be equal to some other field at the moment).""
'''
But later says:
'''""Calls to update can also use F() objects to update one field based on the value of another field in the model.""
'''

Is this a contradiction?

(Thanks, BTW, for your awesome documentation -- I'm really enjoying it!)
