// anyExample_impl.cc - This is the source code of the example used in
//                      Chapter 9 "Type Any and TypeCode" of the omniORB
//                      users guide.
//
//                      This is the object implementation.
//
// Usage: anyExample_impl
//
//        On startup, the object reference is printed to cerr as a
//        stringified IOR. This string should be used as the argument to 
//        anyExample_clt.
