public class JigKill
extends java.lang.Object

Simple class used to save and/or kill Jigsaw.

Options:
  `-u username` User name (defaults to "admin")
  `-p password` Password (required)
  `--username username` Same as `-u`
  `--password password` Same as `-p`
  `--save` Save configuration of all servers
  `--stop` Stop all servers
  `--ping` check if servers are reachable

(The last argument is assumed to be the URL to the Admin server, see Usage examples below...)

Example usage:
  (be sure that jigsaw's `*.jar` file is in CLASSPATH, e.g. `export CLASSPATH=~/Jigsaw/classes/jigsaw.zip: ${CLASSPATH}`)

- Save and exit the server http://gyros.informatik.med.uni-giessen.de:
  `java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj http://gyros.informatik.med.uni-giessen.de:8009/`
  OR (using explicit options)
  `java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj --save --stop http://gyros.informatik.med.uni-giessen.de:8009/`

- Stop a server (as fast as possible, e.g. for system shutdown):
  `java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj --stop http://gyros.informatik.med.uni-giessen.de:8009/`

- Save the servers current configuration:
  `java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj --save http://gyros.informatik.med.uni-giessen.de:8009/`

- Check if a server is still alive:
  `java org.w3c.jigsaw.admin.JigKill -u admin -p for#8pj --ping http://gyros.informatik.med.uni-giessen.de:8009/`

Changes from V1.1 to 1.2:
  - Added `--stop` option: Simply stop jigsaw quick&savely.
  - Added `--save` option: Snapshot the current config (something for a daily crontab job).
  - Added `--ping` option to see if the server is still running (usefull for scripts).
  - Added `--username` and `--password` options as aliases for `-u` and `-p`.

  - 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.
  - `-u` option now defaults to "admin", as jigsaw's default config does.
  - JigKill now saves all servers first before stopping them all (first backup, then destroy...).

ToDo:
  - Adding a `--restart` option.
