+SwiftmailerExtension
+====================
+
+The *SwiftmailerExtension* provides a service for sending
+email through the `Swift Mailer <http://swiftmailer.org>`_
+library.
+
+You can use the ``mailer`` service to send messages easily.
+By default, it will attempt to send emails through SMTP.
+
+Parameters
+----------
+
+* **swiftmailer.options**: An array of options for the default
+  SMTP-based configuration.
+
+  The following options can be set:
+
+  * **host**: SMTP hostname, defaults to 'localhost'.
+  * **port**: SMTP port, defaults to 25.
+  * **username**: SMTP username, defaults to an empty string.
+  * **password**: SMTP password, defaults to an empty string.
+  * **encryption**: SMTP encryption, defaults to null.
+  * **auth_mode**: SMTP authentication mode, defaults to null.
+
+* **swiftmailer.class_path** (optional): Path to where the
+  Swift Mailer library is located.
+
+Services
+--------
+
+* **mailer**: The mailer instance.
+
+  Example usage::
+
+    $message = \Swift_Message::newInstance();
+
+    // ...
+
+    $app['mailer']->send($message);
+
+* **swiftmailer.transport**: The transport used for e-mail
+  delivery. Defaults to a ``Swift_Transport_EsmtpTransport``.
+
+* **swiftmailer.transport.buffer**: StreamBuffer used by
+  the transport.
+
+* **swiftmailer.transport.authhandler**: Authentication
+  handler used by the transport. Will try the following
+  by default: CRAM-MD5, login, plaintext.
+
+* **swiftmailer.transport.eventdispatcher**: Internal event
+  dispatcher used by Swiftmailer.
+
+Registering
+-----------
+
+Make sure you place a copy of *Swift Mailer* in the ``vendor/swiftmailer``
+directory. Make sure you point the class path to ``/lib/classes``.
+
+::
+
+    $app->register(new Silex\Extension\SwiftmailerExtension(), array(
+        'swiftmailer.class_path'  => __DIR__.'/vendor/swiftmailer/lib/classes',
+    ));
+
+.. note::
+
+    Swift Mailer is not compiled into the ``silex.phar`` file. You have to
+    add your own copy of Swift Mailer to your application.
+
+Usage
+-----
+
+The Swiftmailer extension provides a ``mailer`` service.
+
+::
+
+    $app->post('/feedback', function () use ($app) {
+        $request = $app['request'];
+
+        $message = \Swift_Message::newInstance()
+            ->setSubject('[YourSite] Feedback')
+            ->setFrom(array('noreply@yoursite.com'))
+            ->setTo(array('feedback@yoursite.com'))
+            ->setBody($request->get('message'));
+
+        $app['mailer']->send($message);
+
+        return new Response('Thank you for your feedback!', 201);
+    });
+
+For more information, check out the `Swift Mailer documentation
+<http://swiftmailer.org>`_.
