13: PURPOSE: Client side of RPC distributed application
14: FUNCTIONS: main() - binds to server and calls remote procedure
15: COMMENTS:
16: This distributed application prints a string such as "hello, world"
17: on the server. The client manages its connection to the server.
18: The client uses the binding handle hello_IfHandle defined in the
19: file hello.h.
