In CodeIgniter, I can use $autoload['packages'] to specify additional locations for libraries, models, and helpers. But how do I specify additional locations for controllers.
What I want is this: If a URL specifies controller xyzzy, CodeIgniter should first look for the usual application/controllers/Ctrl_xyzzy.php file, and if it doesn't find it, it should look for other_place/controllers/Ctrl_xyzzy.php instead.
Is that possible?
