// eg2_impl.cc - This is the source code of example 2 used in Chapter 2
//               "The Basics" of the omniORB2 user guide.
//
//               This is the object implementation.
//
// Usage: eg2_impl
//
//        On startup, the object reference is printed to cerr as a
//        stringified IOR. This string should be used as the argument to 
//        eg2_clt.
