Symfony 2.1: How to get the Swiftmailer running in combination with /register

gistfile1.md

Insert this into to the bottom of the autoload.php file:

// Swiftmailer needs a special autoloader to allow
// the lazy loading of the init file (which is expensive)
require_once __DIR__.'/../vendor/swiftmailer/lib/classes/Swift.php';
Swift::registerAutoload(__DIR__.'/../vendor/swiftmailer/lib/swift_init.php');
