+	 * following attributes:
+	 *
+	 *   - version: Which version of the source map spec this map is following.
+	 *   - sources: An array of URLs to the original source files.
+	 *   - names: An array of identifiers which can be referrenced by individual mappings.
+	 *   - sourceRoot: Optional. The URL root from which all sources are relative.
+	 *   - sourcesContent: Optional. An array of contents of the original source files.
+	 *   - mappings: A string of base64 VLQs which contain the actual mappings.
+	 *   - file: Optional. The generated file this source map is associated with.
+	 *
+	 * Here is an example source map, taken from the source map spec[0]:
+	 *
+	 *     {

+	 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+	 * 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",
+	 *    sections: [{
+	 *      offset: {line:100, column:10},
+	 *      map: {
