// Usage:
//
// The following code will print a message on screen every time a block is broken in the game
//
// bukkit.on('block.BlockBreakEvent',function(evt){
// print (evt.player.name + " broke a block!");
// });
//
var bukkit = bukkit || {
//
// handle events in Minecraft
// --------------------------
// eventType can be a string (assumed to be a sub package of org.bukkit.event - e.g.
// if the string "block.BlockBreakEvent" is supplied then it's converted to the
// org.bukkit.event.block.BlockBreakEvent class . For custom event classes, just
// supply the custom event class e.g.
// bukkit.on(net.yourdomain.events.YourCustomEvent,function(e){ ... });
//
on: function(
/* String or java Class */ eventType,
/* function */ handler,
/* (optional) String (HIGH, HIGHEST, LOW, LOWEST, NORMAL, MONITOR), */ priority
){}
};
//
// private implementation from here on in...
