"""
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.
