To rebuild or update res/js/polyfill.js you will need to have node.js installed. Once you have it installed run the following (assuming you are in experimental/webtry directory):

$ cd poly $ npm install $ grunt

If you want to create a verion of the polyfill.js that hasn't been minified, say for debugging purposes, then run:

$ cd poly $ npm install $ grunt notmin
