+"""SuperBeam Handlers
+
+SuperBeam Handlers define how to handle certain requests to the
+:class:`SuperBeamServer`. Each handler needs to be registered in ThumbHandler
+`SuperBeamServer.do_GET()` function within the ``paths`` variable and imported
+in the top of the :module:`SuperBeam` module.
+
+The handlers itself are defined in this module.
+
+Each class handler method needs to be a ``staticmethod``. The callee will call
+the `handle()` with the ``httpd`` instance of the :class:`SuperBeamServer`.
