// Compile this program with the following command line.
// C:>csc NStrCli.cs

// To use this program with the companion server program, first start
// the server, then connect to it using the client program (this program)
// in a separate console window.
// As you enter lines from the client, they will appear in the server
// console window. To end the session, press <Enter> on a blank line.
