    //  This example assumes the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    var xmp = new chilkat.Xmp();

    // xml: Xml
    var xml;

    //  The first step is to create a new XMP document, which is nothing
    //  more than XML.  The NewXmp method returns an XML document with
    //  the standard XMP boilerplate.  
    xml = xmp.NewXmp();

    //  Add some properties...
    success = xmp.AddSimpleStr(xml,"Iptc4xmpCore:Chilkat","Blah blah");
    //  If you wish to view the XML, save it to a file and review it
    //  with a text editor:
    success = xml.SaveXml("newXmp.xml");
    if (success !== true) {
        console.log(xml.LastErrorText);
        return;

    //  To add the XMP to the JPG (or TIFF), simply load the JPG,
    //  append the XMP, and save:
    success = xmp.LoadAppFile("scream.jpg");
