 *    This program demonstrates how to build and encode a MIME message, given
 *   
 *   			(1) Simple text
 *   			(2) A file
 *   			(3) Set of RFC822 headers.
 *
 *   The API permits building a message with just a text or a file or both.
 *   Additional files can also be added to the message later on if needed.
 * 
 *   NOTE: For the file the API automatically detects MIME content-types, MIME-Encoding etc.
 *	 However one can also override the MIME encoding.
 *
 *   NOTE: This program works on Windows and on all tested UNIX platforms 
 *         (Solaris, HPUX, AIX, IRIX etc.)
