24   * This is an example of a trivial use of the TelnetClient class.
25   * It connects to the weather server at the University of Michigan,
26   * um-weather.sprl.umich.edu port 3000, and allows the user to interact
27   * with the server via standard input.  You could use this example to
28   * connect to any telnet server, but it is obviously not general purpose
29   * because it reads from standard input a line at a time, making it
30   * inconvenient for use with a remote interactive shell.  The TelnetClient
31   * class used by itself is mostly intended for automating access to telnet
32   * resources rather than interactive use.
