// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

// The goal of this example is to create an email that has this MIME format,
// where the body of the email is XML using base64 encoding, 
// and the Content-Type and Content-Disposition are set as indicated.
