"""
Pages in Django can are served up with custom HTTP headers containing useful
information about those pages -- namely, the content type and object ID.
This module contains utility functions for retrieving and doing interesting
things with these special "X-Headers" (so called because the HTTP spec demands
that custom headers are prefxed with "X-").
Next time you're at slashdot.org, watch out for X-Fry and X-Bender. :)

Adds the "X-Object-Type" and "X-Object-Id" headers to the given
HttpResponse according to the given package, python_module_name and
