This is a simple CodeIgniter 2 installation with Doctrine 2. It contains sample models in application/models/Entity and usage examples in application/controllers/welcome.php.
Dev mode is disabled by default, but you can enable it by setting $dev_mode = true; in application/libraries/Doctrine.php. This will auto-generate proxies and use a non-persistent cache (ArrayCache). Remember to turn dev mode off for production!
