/* This example demonstrates the use of the MIME C-API.
 * Demonstrates building a MIME message from a text 
 * buffer and a file and MIME encoding the same.
 * This covers the most common usage path of user typing
 * some text and attaching an attachment.
 * 
 * Since either of the textBuf and the file attachment need 
 * also not be present this example covers the cases of simple
 * text message or an attachment only message also
