/////////////////////////////////////////////////////////////////////
// This is a stub PSR-4 loading script that gets all the pieces of //
// Smarty 5.x loaded without requiring the use of composer. It's   //
// not really a 'class' file, but the name is used so we're        //
// backwards compatible with previous versions of Smarty.          //
//                                                                 //
// Example:                                                        //
// require_once("/path/to/smarty/libs/Smarty.class.php");          //
//                                                                 //
// $smarty = new Smarty\Smarty;                                    //
// $smarty->testInstall();                                         //
