// 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");

// Note: Requires Chilkat v9.5.0.65 or greater..

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