+"\n	%s:%s\n"
+"\nTo test this program, simply connect a client to that host and port.\n"
+"For example:\n"
+"\n	telnet %s %s\n"
+"\nOnce you have connected a client, the server will echo any characters\n"
+"it receives back to the client as well as to stdout.\n"
+"\nNote that to terminate the telnet client you type Control-], then\n"
+"<Enter>, then \"close\" (and <Enter>) at the \"telnet> \" prompt.\n"
+"\nHave fun!\n"
+"-Carl\n"
+"\nPS. The server does support multiple clients, but there is not yet any\n"
+"interaction between the clients. The next step is probably to turn the\n"
+"server into a simple chat server. After that, we should have the necessary\n"
+"structure in place to start implementing the real tic-tac-toe protocol.\n\n";
