Module Documentation: cc_acc_xmlrpc example Application

Readme file

cc_acc_xmlrpc                contributed by Todd Lewis 

This module implements the accounting functions for the calling
card example, specifically the cc_acc interface. It can be loaded 
as an alternative to the cc_acc module.

Instead of maintaining a local in memory map of credits, as the 
cc_acc module does, it executes the getCredit and subtractCredit
functions via XMLRPC to an accounting server:

This module needs the xmlrpcpp library (see apps/examples/xmlrpc2di module
for details).
