20"""
21 This module implements an xmlrpc server for BitBake.
22
23 Use this by deriving a class from BitBakeXMLRPCServer and then adding
24 methods which you want to "export" via XMLRPC. If the methods have the
25 prefix xmlrpc_, then registering those function will happen automatically,
26 if not, you need to call register_function.
27
28 Use register_idle_function() to add a function which the xmlrpc server
29 calls from within server_forever when no requests are pending. Make sure
30 that those functions are non-blocking or else you will introduce latency
31 in the server's main loop.
