    PURPOSE:    Server side of RPC distributed application Auto
    
    FUNCTIONS:  main() - registers server as RPC server
    
    COMMENTS:   This distributed application (time stamp) is implemented
                using an auto handle.  The server side of the application
                must export its binding information and make it available 
                to the clients.  The auto handle requires a location 
                service running on a server that is accessible to the client.
