+    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.
