	   * 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.
