* A big shout out to the various JavaScript test framework authors, especially TJ for [JSpec](http://github.com/visionmedia/jspec/tree/master) - we played with it a bit before deciding that we really needed to roll our own.
* Huge contributions have been made by [Adam Abrons](mailto:adam@pivotallabs.com), [Lee Byrd](mailto:lee@pivotallabs.com), [Erik Hanson](mailto:erik@pivotallabs.com), [Carl Jackson](mailto:carl@pivotallabs.com), and many other Pivots.
