yep : ['/js/indexeddb-wrapper.js', '/css/coolbrowser.css'],

}
]);

##CHANGELOG##
Version 2 is a significant diversion from Version 1.x. We feel that the direction helps developers make the best decisions for performance rather than enabling poor uses.
Changes in 2.0+ :
- Rewrote entire library

##Thanks##
Dave Artz - A.getJS was a huge code-inspiration for our loader. So he's responsible for a ton of awesome techniques here.
Kyle Simpson - He is the creator of LABjs of which a lot of this is inspired by.
Stoyan Stefanov - His work on resource preloading has been awesome: (http://www.phpied.com/preload-cssjavascript-without-execution/)[http://www.phpied.com/preload-cssjavascript-without-execution/]
Steve Souders - His evangelism and work in the space (ControlJS) have brought light to the issues at hand, he is the father of front-end performance.
Paul Irish - Thanks or whatever.
