获取资产文件的文件名

I'm building a web app using Symfony2 with Assetic. I would like to make a manifest file , but I have to manually add the file names to the list.

I can use PHP to get all static files (in [app/Bundle]/Resources/public), so I can generate of list of those files easily. But the other files (stylesheets, javascripts and images) are being generated by Assetic.

Is there a way to get a list of those generated files, so I can add them to a manifest-file?

All files are registered in router

php app/console debug:router

You can see what the command is doing, by viewing the source: Symfony/Bundle/FrameworkBundle/Command/RouterDebugCommand.php. You can extract what you need.
