""" A registry object is an :term:`application registry`. It is used by
the framework itself to perform mappings of URLs to view callables, as
well as servicing other various framework duties. A registry has its own
internal API, but this API is rarely used by Pyramid application
developers (it's usually only used by developers of the Pyramid
framework). But it has a number of attributes that may be useful to
application developers within application code, such as ``settings``,
which is a dictionary containing application deployment settings.
For information about the purpose and usage of the application registry,
see :ref:`zca_chapter`.
The application registry is usually accessed as ``request.registry`` in
application code.
