 This library also works in Chrome. While the DevTools console already supports source maps, the V8 engine doesn't and `Error.prototype.stack` will be incorrect without this library. Everything will just work if you deploy your source files using [browserify](http://browserify.org/). Just make sure to pass the `--debug` flag to the browserify command so your source maps are included in the bundled code.
