Author:       Fran鏾is PIETTE (original)
              Marco van de Voort (ugly hack to console)
Object:       Show how to use TPop3Prot (POP3 protocol, RFC-1225)
              Written with a service that checks a pop3box for
              commands/input in mind.
Credit:       Marco van de Voort <[e-mail]> ported my GUI code
              (MailRcv demo) to console mode.
Creation:     Sep 2003 (From GUI version created 03 october 1997)
