Question from the Symfony 2 test

In the framework configuration, multiple asset configurations can coexist in the form of freely named configuration packages.

The assets of the bundles are automatically published in the /web directory at each cache cleaning by the cache cleaning command:

php app/console cache:clear

The asset version does not automatically increment at each cache cleaning by the cache cleaning command:

php app/console cache:clear

The Assetic bundle is included by default to natively facilitate asset management.
