//
//   This program shows how to use the Middleware Service to send 
//   data to another program.
//   
//
//   The following Middle code was used as input to the Middleware
//   Service: 
//         MsgManager
//           (vector<int>, char*) @MSGID_1
//           (set<int>) @MSGID_2
//           (unsigned int) @IN
//         }
//
//   The output from the Middleware Service was stored in a 
//   file called MsgManager.hh.
