How to integrate Stripe with Lithium

libraries.php

<?php

/** config/bootstrap/libraries.php **/

// ...

Libraries::add('stripe', array(
	'path' => LITHIUM_APP_PATH . '/libraries/stripe/lib',
	'prefix' => null
));

?>

So what i get confused about is how do I then use it in my controllers. Do I have to bootstrap it and tell it to load all the classes manually? And where does namespacing come in to it? Basically, I would love to be able to do something like:

namespace app\controllers;

use libraries\stripe;

class SomethingController extends etcController {
 public function view() {
  $charge = Charge::create($params);
 }
}
