How to use Assetic with CacheBustingWorker and twig

Question

As i can see Assetic made some progress on CacheBusting:
https://github.com/kriswallsmith/assetic#cache-busting

But i dont really understand how i should use this.
Can this be used from within twig:

{% stylesheets 'bundles/mybundle/css/fonts.css' 
               'bundles/mybundle/css/style.css'
               'bundles/mybundle/css/screen.css'
               filter='cssrewrite'
 %}
    <link rel="stylesheet" type="text/css" href="{{ asset_url }}" />
{% endstylesheets %}

And with the usual assetic:dump command?

Where would i have to hook the CacheBustingWorker in?

Cache buster is now part of symfony/AsseticBundle (Version >= 2.5.0).

Change AsseticBundle version in composer.json like that:

"symfony/assetic-bundle": "2.5.0",

And activate cache busting for assets in your config.yml file like that

assetic:
    workers:
        cache_busting: ~

My JS files are now looking like that:

web/bundles/js/projectname-876f9ee.js

See https://github.com/symfony/AsseticBundle/pull/119#issuecomment-28877145
