docs: WSGI adapter. It creates a simple WSGI application, that can be used with
      any WSGI server. The arguments are:
  
      #. ``server`` is a pyws server object,
      #. ``root_url`` is an URL to which the server will be bound.
  
      An application created by the function transforms WSGI environment into a
      pyws request object. Then it feeds the request to the server, gets the
      response, sets header ``Content-Type`` and returns response text.
