  [./symfony plugin:upgrade sfGuardPlugin|INFO]

The default channel is [symfony|INFO].

If the plugin contains some web content (images, stylesheets or javascripts),
the task also updates the [web/%name%|COMMENT] directory content on Windows.

See [plugin:install|INFO] for more information about the format of the plugin name and options.
