+ * This is a simple example of use of TelnetClient.
+ * An external option handler (SimpleTelnetOptionHandler) is used.
+ * Initial configuration requested by TelnetClient will be:
+ * WILL ECHO, WILL SUPPRESS-GA, DO SUPPRESS-GA.
+ * VT100 terminal type will be subnegotiated.
+ * <p>
+ * Also, use of the sendAYT(), getLocalOptionState(), getRemoteOptionState()
+ * is demonstrated.
+ * When connected, type AYT to send an AYT command to the server and see
+ * the result.
+ * Type OPT to see a report of the state of the first 25 options.

+/***
+ * This is an example program demonstrating how to use the RCommandClient
+ * class. This program connects to an rshell daemon and requests that the
+ * given command be executed on the server.  It then reads input from stdin
+ * (this will be line buffered on most systems, so don't expect character
+ * at a time interactivity), passing it to the remote process and writes
+ * the process stdout and stderr to local stdout.
+ * <p>
+ * On Unix systems you will not be able to use the rshell capability
+ * unless the process runs as root since only root can bind port addresses
+ * lower than 1024.
+ * <p>
+ * Example: java rshell myhost localusername remoteusername "ps -aux"
+ * <p>
+ * Usage: rshell <hostname> <localuser> <remoteuser> <command>
+ * <p>
