-- demo\rosetta\ChatServer.exw
-- ========================
--
-- translation of (qchat) chatServ.exw
--
-- Run this first, then ChatClient.exw, see also IRC_Gateway.exw
--
-- Note that I've only got a 32-bit windows eulibnet.dll, but it should not
-- be dificult to use a "real" libnet.dll/so, or something a little newer.
