-/** |
- * @fileoverview NTP Standalone hack |
- * This file contains the code necessary to make the Touch NTP work |
- * as a stand-alone application (as opposed to being embedded into chrome). |
- * This is useful for rapid development and testing, but does not actually form |
- * part of the product. |
- * |
- * Note that, while the product portion of the touch NTP is designed to work |
- * just in the latest version of Chrome, this hack attempts to add some support |
- * for working in older browsers to enable testing and demonstration on |
- * existing tablet platforms. In particular, this code has been tested to work |
- * on Mobile Safari in iOS 4.2. The goal is that the need to support any other |
- * browser should not leak out of this file - and so we will hack global JS |
- * objects as necessary here to present the illusion of running on the latest |
- * version of Chrome. |
- */ |
- |
-// Note that this file never gets concatenated and embeded into Chrome, so we |
-// can enable strict mode for the whole file just like normal. |

- * don't bother simulating it here. |
