13: PURPOSE: Client side of RPC distributed application
14: FUNCTIONS: main() - binds to server and calls remote procedure
15: COMMENTS:
16: This version of the distributed application prints
17: strings from the Doctor server. Doctor is an Eliza-like
18: personal therapist program that works by simple pattern-matching.
