    // First populate a simple email.

    email.Body = "This is a simple email body."
    email.From = "Chilkat Software <support@chilkatsoft.com>"
    email.AddTo("Some Recipient", emailAddress: "someRecipient@somewhere.com")

    // Load a JPG file.
    // The actual source of your attachment data can come from anywhere.
    // The point here is that we're first getting the bytes in memory, and THEN adding
    // the bytes as an attachment.
    let fac = CkoFileAccess()
    var jpgBytes: NSData
    jpgBytes = fac.ReadEntireFile("qa_data/jpg/starfish20.jpg")

    // Add the JPG bytes via AddDataAttachment.
    email.AddDataAttachment("tinyStarfish.jpg", content: jpgBytes)

    // We could also add the JPG and explicitly set the content-type w/ AddDataAttachment2
    email.AddDataAttachment2("teenyStarfish.jpg", content: jpgBytes, contentType: "image/jpg")

    // Examine the MIME:
    print("\(email.GetMime())")
