* This file should run before config.php requires '/lib/setup.php'.

|
|
* Main purpose of this file:
|
|
* 1) Create a hook allowing other scripts to run before Moodle loads, but after the $CFG is defined.
|
|
* 2) Allow to 'pretend' maintenance mode for non-allowed IPs by calling 'climaintenance.php'.
|
|
* 3) Set a flag that this file was loaded so we can warn users if this config is not working.
