Moodle: Use config.php vars (CFG) loading minimum data

Hello,

Sometimes, in a custom moodle script or in your local plugin you need $CFG vars but you don't need all moodle features.
The best option is write:

define('NO_DEBUG_DISPLAY', true);
define('ABORT_AFTER_CONFIG', true);
require_once('../../config.php');

...

With this code, you could, for example, execute echo $CFG->dbhost
