action_autoload.php
Action Stack Autoloader.
Loads the Symfony 1.x action/component class hierarchy in dependency order. All classes are guarded with class_exists() — they never override real Symfony classes.
Load order:
- sfParameterHolder (used by sfComponent)
- sfException → sfStopException, sfError404Exception
- sfComponent (base)
- sfAction (extends sfComponent)
- sfActions (extends sfAction)
- sfComponents (extends sfComponent)
