+Multiple view prefixes
+----------------------
+
+In practice, you'll probably end up mixing and matching views to the point
+where the views in your ``urlpatterns`` won't have a common prefix. However,
+you can still take advantage of the view prefix shortcut to remove duplication.
+Just add multiple ``patterns()`` objects together, like this:
+
+Old::
+
+    from django.conf.urls.defaults import *
+
+    urlpatterns = patterns( ''
+        (r'^/?$', 'django.views.generic.date_based.archive_index'),
+        (r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/$', 'django.views.generic.date_based.archive_month'),
+        (r'^tag/(?P<tag>\w+)/$', 'weblog.views.tag'),
+    )
+
+New::
+
+    from django.conf.urls.defaults import *
+
+    urlpatterns = patterns('django.views.generic.date_based'
+        (r'^/?$', 'archive_index'),
+        (r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/$','archive_month'),
+    )
+
+    urlpatterns += patterns('weblog.views',
+        (r'^tag/(?P<tag>\w+)/$', 'tag'),
+    )
+
