 * ${CLASSPATH}</CODE>)</DD>
 * <DL><DT>- Save and exit the server 
 * http://gyros.informatik.med.uni-giessen.de:
 *   <DD><CODE>java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj 
 * http://gyros.informatik.med.uni-giessen.de:8009/</CODE></DD>
 *
 *   <DD>OR (using explicit options)</DD>
 *
 *   <DD><CODE>java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj 
 * --save --stop http://gyros.informatik.med.uni-giessen.de:8009/</CODE></DL> 
 *
 * <DL><DT>- Stop a server (as fast as possible, e.g. for system shutdown):
 *   <DD><CODE>java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj 
 * --stop http://gyros.informatik.med.uni-giessen.de:8009/</CODE></DL>
 *
 * <DL><DT>- Save the servers current configuration:
 *   <DD><CODE>java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj 
 * --save http://gyros.informatik.med.uni-giessen.de:8009/</CODE></DL>
 *
 * <DL><DT>- Check if a server is still alive:
 *   <DD><CODE>java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj 
 * --ping http://gyros.informatik.med.uni-giessen.de:8009/</CODE></DL></DL>
 * <P>
 * <DL>
 * <DT><B>Changes from V1.1 to 1.2:</B>
 * <DD>- Added <CODE>--stop</CODE> option: Simply stop jigsaw quick&savely.
 * </DD>
 * <DD>- Added <CODE>--save</CODE> option: Snapshot the current config 
 * (something for a daily crontab job).</DD>
 * <DD>- Added <CODE>--ping</CODE> option to see if the server is still 
 * running (usefull for scripts).</DD>
 * <DD>- Added <CODE>--username</CODE> and <CODE>--password</CODE> options 
 * as aliases for <CODE>-u</CODE> and <CODE>-p</CODE>.</DD></DL>
 * 
 * <DD>- JigKill now returns 0 for success and non-0 for failure 
 * (of the requested operation) EVERYTIMES 
 *   (except the JVM cores) to make script-processing as much as easy.</DD>
 * <DD>- <CODE>-u</CODE> option now defaults to "admin", as jigsaw's 
 * default config does.</DD>
 * <DD>- JigKill now saves all servers first before stopping them all 
 * (first backup, then destroy...).</DD></DL>
 * <P>
 * <DL>
 * <DT><B>ToDo:</B>
 * <DD>- Adding a <CODE>--restart</CODE> option.</DD></DL>
