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

    // Start with an empty MIME object...
    let mime = CkoMime()!

    // Initialize it as multipart/alternative.
    mime.newMultipartAlternative()

    // Create a text/plain part.
    let ptMime = CkoMime()!
    ptMime.setBody(fromPlainText: "This is the plain text body.")
    print("\(ptMime.getMime()!)")
    print("****")

    // 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.
    let htmlMime = CkoMime()!
    htmlMime.setBody(fromHtml: "<html><body><p>This is the <b>HTML body</b></p></body></html>")
    print("\(htmlMime.getMime()!)")
    print("****")

    // 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(mime: ptMime)
    mime.appendPart(mime: htmlMime)
    print("\(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
    // 
    // 	<html><body><p>This is the <b>HTML body</b></p></body></html>
    // 	--------------080803090906030708030908--
