// eg2_impl.cc - This example is similar to that found in:
//                  <top>/src/examples/echo/eg2_impl.cc
//               except that the object reference is the same each time.
//
// Usage: eg2_impl -ORBpoa_iiop_port <portnum>
//
//        On startup, the object reference is printed to stderr as a
//        stringified IOR. This string should be used as the argument to 
//        eg2_clt.
//
//        If the same port number is given at each invocation, then the same
//        object reference is issued each time.  It is also possible to
//        specify the port number from an application, by inserting the
//        relevant option into argc,argv before passing to CORBA::ORB_init().
//        See <top>/src/appl/omniNames/omniNames.cc for an example.
