      ``global_conf``
          The inherited configuration for this application. Normally from
          the [DEFAULT] section of the Paste ini file.
  
      ``full_stack``
          Whether this application provides a full WSGI stack (by default,
          meaning it handles its own exceptions and errors). Disable
          full_stack when this application is "managed" by another WSGI
          middleware.
  
      ``static_files``
          Whether this application serves its own static files; disable
          when another web server is responsible for serving them.
  
      ``app_conf``
          The application's local configuration. Normally specified in
          the [app:<name>] section of the Paste ini file (where <name>
          defaults to main).
