Note: he is only providing source code at this time, so you need to be able to compile it yourself.
The intention was always for people write their own listeners. As an example you could send yourself an email when you're results get posted. That way you can just leave it running and put the whole "waiting for results" thing to the back of your mind.
To make that process a little easier I plan on adding a binary release with a configuration option that allows you to specify the class name of any custom listener(s). Then you can simply add your own code to the classpath, without the need to checkout and compile the scraper source.
