                Hello Example

    FILE:   helloc.c
    USAGE:   client    -n network_address
          -p protocol_sequence
          -e endpoint
          -o options
          -u 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 binding handle hello_IfHandle defined in the
    file hello.h.
