/**
 * Main program./* w w  w. j a  v a 2 s  .  c  o m*/
 * <p>
 * Usage: <command> <remote_host> [-user <user>] [-reboot | -command <command>] [-interactive] [-logOutput] [-wait [seconds]] [-log4jconf <properties_file>]
 *   remote_host: remote host
 *   -user <user>: remote user
 *   -reboot: reboot remote host
 *   -command <command>: send command to remote host
 *   -interactive: enable interactive mode, i.e. sending commands from standard input, this also enables the wait parameter
 *   -logOutput: enable logging of remote host output
 *   -wait [seconds]: wait until connection is closed or given seconds
 *   -log4jconf <properties_file>: use given file as log4j properties file
