Get a Stack Trace on the Symfony2 Command line (console)

If you run a command via the Symfony 2 Console component and receive an exception, you aren't presented with much more information than the exception name and message.

To see a full stack trace, append -v to your command.

For example:

php app/console doctrine:schema:update --force -v

This will provide a full stack trace. You probably need to have Xdebug installed.
