TODO: Some waffle to go in here... in the interim, you can check out the source on GitHub, the blog post, or send me a message on Twitter.

Instead of a regular HTML web page, you can get output in formats such as JSON, XML or plain text - until I get round to updating this text, have a look at the blog post or the code for more info.
