                       Cluuid Example

    FILE:        cluuidc.c

    USAGE:       cluuidc  -n network_address
                          -p protocol_sequence
                          -e endpoint
                          -o options
                          -s string_displayed_on_server
                          -u client object uuid

    PURPOSE:     Client side of RPC distributed application

    FUNCTIONS:   main() - binds to server and calls remote procedure

    COMMENTS:    This distributed application prints a string such as 
                 "hello, world" on the server. The client manages its 
                 connection to the server. The client uses the implicit 
                 binding handle ImpHandle defined in the file cluuid.h.
