/** Main stop class.
 * This class is intended to be the main class listed in the MANIFEST.MF  of
 * the stop.jar archive. It allows an application started with the
 * command "java -jar start.jar" to be stopped.
 *
 * Programs started with start.jar may be stopped with the stop.jar, which connects
 * via a local port to stop the server. The default port can be set with the
 * STOP.PORT system property (a port of < 0 disables the stop mechanism). If the STOP.KEY
 * system property is set, then a random key is generated and written to stdout. This key
 * must be passed to the stop.jar.
