-### Auto include, based on a directory
-
-If there is a `pi.dir.php` file in a `directory`, it is automatically included, wherever you include/require `piLoader` in php files in that `directory`.
-
-**example**: `./user/pi.dir.php`
-```php
-<?php
-//here you can already use a php-includer object, it is already included
-include $pi->path("conf/config.php");
-
-//restrict the access
-if (userIsNotLoggedIn) {
-    require $pi->path("login/index.php"); //requires "/var/www/myApp/login/index.php"
-}
-```
-
-`./user/pi.dir.php` will be applied to all files in (and only) the `./user` directory that includes the `piLoader`.
-
-**note**: `pi.dir.php` inclusion behavior does not act recursively - that is, no eventual `pi.dir.php` from parent directory is included
