It's a bit more robust to use django.http.get_host() -- which is also
available as the get_host() method on the request object in recent
Django code (that was added in [6166]).

The comment at the top of django/template/loader.py gives the details,
but it's pretty simple. Look at one of the existing loaders (in
django/template/loaders/) for inspiration. The filesystem loader is
probably the simplest. The only thing you need to do to identify your
loader function is set the "is_usable" attribute on the function to True
-- you can give it any name you like, although all of Django's core
loaders use load_template_source() for consistency.

You can use the ORM if you want to. For example, there's a full-blown
template loader that loads templates from the database itself. See
http://code.google.com/p/django-databasetemplateloader/ .
