- 	 * input.
 
- 	 *
 
- 	 * The only parameter is a raw source map (either as a JSON string, or already
 
- 	 * parsed to an object). According to the spec for indexed source maps, they
 
- 	 * have the following attributes:
 
- 	 *
 
- 	 *   - version: Which version of the source map spec this map is following.
 
- 	 *   - file: Optional. The generated file this source map is associated with.
 
- 	 *   - sections: A list of section definitions.
 
- 	 *
 
- 	 * Each value under the "sections" field has two fields:
 
- 	 *   - offset: The offset into the original specified at which this section
 
- 	 *       begins to apply, defined as an object with a "line" and "column"
 
- 	 *       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",
