Simple bot base includes CommandHandler and Config system.

@CommandName("ping")
@CommandDescription("Pong!")
public class PingCommand extends Command {

    @Override
    public void handle(CommandParameters cmd) {
        cmd.getTextChannel().sendMessage("Pong!").queue();
    }
}

Optionally you can use final class and final handle method. This will be nicer.
