from django.views.generic.simple import direct_to_template, redirect_to

urlpatterns = patterns('',
  url(r'^robots\.txt$', 'django.views.generic.simple.direct_to_template',
    {'template': 'robots.txt', 'mimetype': 'text/plain'}),
  url(r'^favicon\.ico$', 'django.views.generic.simple.redirect_to',
