* Announces a countdown to every player, writes all online characters to the
|

|
|
* database (skills/powers, stat modifiers, experience) and then stops the
|
||
|
|
* login and world servers. Unlike './reboot' - which simply runs mbrestart.sh
|
||
|
|
* and therefore kills the JVMs with SIGKILL - nothing still parked in a
|
||
|
|
* deferred database job is lost.
|
||
|
|
*
|
||
|
|
* Usage: ./shutdown [seconds] (default 60, maximum 3600)
