App Handler
===========

There is one handler which corresponds to the app itself, whereas all
other handlers correspond to some "portion" of the app.  This main app
handler's primary purpose is to:

- provide a common interface for obtaining all other handlers
- provide some "global" methods, e.g. for rendering date/time values

You can override the main app handler, with config like:

.. code-block:: ini

   [rattail]
   app.handler = poser.app:PoserAppHandler

Of course that must point to a valid ``AppHandler`` class, which you
probably must create.

See also :class:`rattail:rattail.app.AppHandler` which is the default
and base class.
