-    A simple decorator that requires a user to be logged in. If they are not
-    logged in the request is examined for a 'authorization' header.
-
-    If the header is present it is tested for basic authentication and
-    the user is logged in with the provided credentials.
-
-    If the header is not present a http 401 is sent back to the
-    requestor to provide credentials.
-
-    The purpose of this is that in several django projects I have needed
-    several specific views that need to support basic authentication, yet the
-    web site as a whole used django's provided authentication.
-
-    The uses for this are for urls that are access programmatically such as
-    by rss feed readers, yet the view requires a user to be logged in. Many rss
-    readers support supplying the authentication credentials via http basic
-    auth (and they do NOT support a redirect to a form where they post a
-    username/password.)
-
-    Use is simple:
-
-    @logged_in_or_basicauth
-    def your_view:
-        ...
-
-    You can provide the name of the realm to ask for authentication within.
