CakeResqueBootstrap.php is quite old and carries 1.3 bits.
This approach, loads and instantiates the core's ShellDispatcher (replicating the logic inside lib/Cake/Console/cake.php), without actually calling ShellDispatcher::run(), with the benefit of using the actual logic to init all constants, handlers and environments.
Also, App class magic can be later used to load other classes.
