/***
 * This is an example program demonstrating how to use the RExecClient class.
 * This program connects to an rexec server 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>
 * Example: java rexec myhost myusername mypassword "ps -aux"
 * <p>
 * Usage: rexec <hostname> <username> <password> <command>
 * <p>
