Still exploring the ideas that came when writing the tutorial. lino.tutorials.t2 now works with either urls (Lino on top; this is equivalent to not setting ROOT_URLCONF at all) or urls2 (Lino under /lino).

lino.tutorials.t2.urls3 shows how it is theoretically possible to install both Django’s admin and Lino in parallel. But the details are left for those who are interested; Basically you just need to uncomment the related lines below. But this tutorial still gets an ImproperlyConfigured error “Put ‘django.contrib.auth.context_processors.auth’ in your TEMPLATE_CONTEXT_PROCESSORS setting in order to use the admin application.”
