Create a Phar for SwiftMailer

It's very simple to create a phar out of an existing php code tree.

<?php
  $phar = new Phar('swiftmailer.phar', 0, 'swiftmailer.phar');
  // add all files in the project
  $phar->buildFromDirectory(dirname(__FILE__) . '/swiftmailer');
  $phar->setStub($phar->createDefaultStub('swift_required.php'));
?>
