// RmCheckersClient.java is a client that interacts with Sam, a checkers
// server. It is designed to illustrate how to communicate with the server
// in a minimal way. It is not meant to be beautiful java code.
// Given the correct machine name and port for the server, a user id, and a
// password (_machine, _port, _user, and _password in the code), running
// this program will initiate connection and start a game with the default
// player. (the _machine and _port values used should be correct, but check
// the protocol document.)
//
// the program has been tested and used under Java 5.0, and 6.0, but probably
// would work under older or newer versions. (also works under Java 8).
