- Add a ``get_app`` API functions to the ``paster`` module. This

  obtains a WSGI application from a config file given a config file
  name and a section name.  See the ``repoze.bfg.paster`` API docs for
  more information.

- Add a new module named ``scripting``.  It contains a ``get_root``
  API function, which, provided a Router instance, returns a traversal
  root object and a "closer".  See the ``repoze.bfg.scripting`` API
  docs for more info.
