''' Define standard endpoints and their associated views for a Bokeh Server
application.

These will be added by the :class:`~bokeh.server.tornado.BokehTornado`
application. The Bokeh Tornado application can then be served using Tornado's
built-in ``HTTPServer``.

.. data:: toplevel_patterns
    :annotation:

    Top-level routes, independent of any applications. They will be prefixed
    with any configured prefix.

    .. code-block:: python

        [
            ( r'/?',           RootHandler   ), # <prefix>/
            ( r'/static/(.*)', StaticHandler ), # <prefix>/static/
        ]

.. data:: per_app_patterns
    :annotation:

    Per-application routes. These be prefixed with the application path, as
    well as with any configured prefix.
