 This module provide quick access to SilverStripe's built in [URL Variable Tools](http://doc.silverstripe.org/framework/en/reference/urlvariabletools) but reading their output isn't much fun. You can peek under SilverStripe's hood much more conveniently using the recently released [SilverStripe Clockwork](https://github.com/markguinn/silverstripe-clockwork) by Mark Guinn.
