The only new thing is the handleMessage method.

    public void handleMessage (KaaribogaMessage msg){
        System.out.println ("MessageReceiver: Received Message.");      
        System.out.println ("           Kind: " + msg.kind);    
        System.out.println ("        Content: " + msg.content); 
    }

This method is used to handle all kinds of messages. By default the Kaariboga.handleMessage method just ignores all incoming messages. You are not restricted to the types of messages that are defined in the message class. Instead you may use arbitrary strings for the kind field, for example you could program an agent that operates on a data base and only accepts kind = DS_SQL messages. Note that here the DS_ namespace is used to avoid confusion with messages defined by othe programmers.
