|  | 	 *       field. | ||
|  | 	 *   - map: A source map definition. This source map could also be indexed, | ||
|  | 	 *       but doesn't have to be. | ||
|  | 	 * | ||
|  | 	 * Instead of the "map" field, it's also possible to have a "url" field | ||
|  | 	 * specifying a URL to retrieve a source map from, but that's currently | ||
|  | 	 * unsupported. | ||
|  | 	 * | ||
|  | 	 * Here's an example source map, taken from the source map spec[0], but | ||
|  | 	 * modified to omit a section which uses the "url" field. | ||
|  | 	 * | ||
|  | 	 *  { | ||
|  | 	 *    version : 3, | ||
|  | 	 *    file: "app.js", | ||

|  | 	 *      map: { | ||
