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

    // Start with an empty MIME object...
    var mime = new chilkat.Mime();

    // Initialize it as multipart/alternative.
    mime.NewMultipartAlternative();

    // Create a text/plain part.
    var ptMime = new chilkat.Mime();
    ptMime.SetBodyFromPlainText("This is the plain text body.");
    console.log(ptMime.GetMime());
    console.log("****");

    // The text/plain part looks like this:

    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body.

    // Create a text/HTML part.
    var htmlMime = new chilkat.Mime();
    htmlMime.SetBodyFromHtml("<html><body><p>This is the <b>HTML body</b></p></body></html>");
    console.log(htmlMime.GetMime());
    console.log("****");

    // The text/html part looks like this:

    // 	Content-Type: text/html
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	<html><body><p>This is the <b>HTML body</b></p></body></html>

    // Add both parts as children of the multipart/alternative
    mime.AppendPart(ptMime);
    mime.AppendPart(htmlMime);
    console.log(mime.GetMime());

    // This the result.  The boundary string was automatically generaetd.

    // 	Content-Type: multipart/alternative; boundary="------------080803090906030708030908"
    // 
    // 	--------------080803090906030708030908
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body.
    // 	--------------080803090906030708030908
    // 	Content-Type: text/html
    // 	Content-Transfer-Encoding: 7bit
