Some changes to the conf.py
===========================

To get sphinx autodoc work I add to the conf.py a path to the project
directory and a path to the GAE SDK which contain some required
libraries::

  # todo: Please specify `gae_path' below (a path to the google app
  # engine SDK directory)

  gae_path = '~/google_appengine'

  gae_path = os.path.expanduser(gae_path)
  sys.path.insert(0, os.path.abspath('../'))
  sys.path.insert(0, os.path.abspath(gae_path))
  sys.path.insert(0, os.path.abspath(os.path.join(gae_path, 'lib/yaml/lib')))
  sys.path.insert(0, os.path.abspath(os.path.join(gae_path, 'lib/webapp2')))
  sys.path.insert(0, os.path.abspath(os.path.join(gae_path, 'lib/webob_1_1_1')))
  logging.debug('sys.path: %s', sys.path)
