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