+ * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+ * input.
+ *
+ * The first 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: {
+ * version : 3,
+ * file: "section.js",
+ * sources: ["foo.js", "bar.js"],
+ * names: ["src", "maps", "are", "fun"],
+ * mappings: "AAAA,E;;ABCDE;"
+ * }
+ * }],
+ * }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found. This URL is used to compute the
+ * sources array.

+ // > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
