Update some of the URL patterns to get their link_name parsing from the new patterns in key_name.py. (Using it like this in urls.py is why key_name.py needs to not depend on other modules...)

from django.conf.urls.defaults import *

urlpatterns = patterns('',
    (r'^$', 'examples.views.index'),
    (r'^hello/', include('examples.hello.urls')),
)
