How do I set up the service in cpp code template which references a python service? The example for cpp client requires a .h file for the service:

2        #include "beginner_tutorials/AddTwoInts.h" 
...
15       ros::ServiceClient client = n.serviceClient("add_two_ints"); 

But even by looking at the github sources for node_handle, I'm not able to figure out the way to call this when the service is python based. The examples / tutorials further illustrate that cpp client can talk to a python service (and the other way around), but this is based on building both client and service in their respective worlds.
