Demonstrates the AppendPart method for adding sub-parts to MIME.

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

    var success bool

    // Create a text/plain part.
    ptMime := chilkat.NewMime()
    ptMime.SetBodyFromPlainText("This is the plain text body")
    fmt.Println(*ptMime.GetMime())
    fmt.Println("****")

    // The ptMime contains:
    // ---------------------------------------
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // ---------------------------------------

    // Start with an empty MIME object...
    topLevelMime := chilkat.NewMime()

    // Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
    topLevelMime.NewMultipartMixed()

    // Append the ptMime as a child.
    topLevelMime.AppendPart(ptMime)
    fmt.Println(*topLevelMime.GetMime())
    fmt.Println("****")

    // The topLevelMime contains:
    // --------------------------
    // 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
    // 
    // 	--------------010907090104040508040404
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // 	--------------010907090104040508040404--
    // 

    // IMPORTANT: A copy of the MIME passed in AppendPart is appended.
    // Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
    // For example:
    ptMime.SetBody("this is the new plain text body.")
    // topLevelMime is unchanged.
    fmt.Println(*topLevelMime.GetMime())
    fmt.Println("****")

    // To change the content in topLevelMime, we must get the text/plain part.
    // For example:
    ptMime2 := topLevelMime.GetPart(0)
    ptMime2.SetBody("this is the new plain text body.")
    ptMime2.DisposeMime()
    // Now topLevelMime is changed.
    fmt.Println(*topLevelMime.GetMime())

    ptMime.DisposeMime()
    topLevelMime.DisposeMime()
