+    This module implements an xmlrpc server for BitBake.
+
+    Use this by deriving a class from BitBakeXMLRPCServer and then adding
+    methods which you want to "export" via XMLRPC. If the methods have the
+    prefix xmlrpc_, then registering those function will happen automatically,
+    if not, you need to call register_function.
+
+    Use register_idle_function() to add a function which the xmlrpc server
+    calls from within server_forever when no requests are pending. Make sure
+    that those functions are non-blocking or else you will introduce latency
+    in the server's main loop.
