+# XMLRPC example
+##################################################
+
+XMLRPC allows software to make remote function calls over http. 
+In the case of GRC, one can use XMLRPC to modify variables in a running flow graph.
+See http://www.xmlrpc.com/
+
+--- Server Example ---
+Place an "XMLRPC Server" block inside of any flow graph. 
+The server will provide set functions for every variable in the flow graph.
+If a variable is called "freq", the server will provide a function set_freq(new_freq).
+Run the server example and experiment with the example client script.
+
+-- Client Example --
+The "XMLRPC Client" block will give a variable control over one remove function.
+In the example client, there is one client block and gui control per variable.
+This technique can be used to remotely control a flow graph, perhaps running on a non-gui machine.
