The [project:freeze|INFO] task copies all the symfony core files to
the current project:

  [./symfony project:freeze /path/to/symfony/data/directory|INFO]

The task takes a mandatory argument of the path to the symfony data
directory.

The task also changes [config/config.php|COMMENT] to switch to the
embedded symfony files.
