    This file adds these methods to JavaScript:

        object.toJSONString()

            This method produces a JSON text from an object. The
            object must not contain any cyclical references.

        array.toJSONString()

            This method produces a JSON text from an array. The
            array must not contain any cyclical references.

        string.parseJSON()

            This method parses a JSON text to produce an object or
            array. It will return false if there is an error.
