Is there a list of Symfony2 default container services?

Question

Here is an example, taken from Symfony2 website, about defining a custom service (YAML notation):

services:
    newsletter_manager:
                 


        

Answer 1

The WebProfilerExtraBundle is very useful for this.

It also adds some details about routing, assetic and twig that are very helpful. As a someone learning to think in Symfony, I REALLY like this bundle.
