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

    var zip = new chilkat.Zip();

    var success = zip.NewZip("test.zip");
    if (success !== true) {
        console.log(zip.LastErrorText);
        return;
    }

    // Append a directory tree.  The call to AppendFiles does
    // not read the file contents or append them to the zip
    // object in memory.  It simply appends references
    // to the files so that when WriteZip or WriteZipAndClose 
    // is called, the referenced files are streamed and compressed
    // into the .zip output file.

    var recurse = true;
    success = zip.AppendFiles("c:/temp/a/*",recurse);
    if (success !== true) {
        console.log(zip.LastErrorText);
