  // See Global Unlock Sample for sample code.

  const mht = new Mht();

  // Download a URL into an in-memory MHT web archive contained
  // in a string variable.
  // The following URL is randomly picked and was valid at the time of writing this example:
  let mhtDoc: string;
  try {
    mhtDoc = await mht.getMHTAsync('https://www.tetonlodge.com/');
  } catch {
    console.log(mht.lastErrorText);
    return;
  }

  // Extract the HTML and embedded objects:
  const unpackDir = 'C:/AAWorkarea/mhtTesting/';
  const htmlFilename = 'lodge.html';
  const partsSubdir = 'objects';

  // Extract to C:/AAWorkarea/mhtTesting/lodge.html.
  // images and other embedded objects are placed in
  // C:/AAWorkarea/mhtTesting/objects.  Directories are automatically
  // created if they don't already exist.
  try {
    mht.unpackMHTString(mhtDoc, unpackDir, htmlFilename, partsSubdir);
    console.log('Unpacked!');
  } catch {
