 - No Map() object is used or needed here.
 - Be sure to call self.finalize() once you've registered everything! This will
   validate everything and let you know if there's problems.
+- You can associate more styles to a given layer by passing a tuple of style
+  names along with the layer itself to register_layer().  As of this writing

+Conclusion
+----------
+
+	This is the very first implementation of a WMS for Mapnik.  Although inital
+testing seems to suggest it works well, there may be bugs, and it lacks some
+useful features.  Comments, contributions, and requests for help should all be
+directed to the Mapnik mailing list.

+Enjoy!
