 * Set configuration parameters that are not in the table config. In the

 * coming from config table or config_default.inc.php.
 *
 * It is recommended to let config_default.inc.php as provided and to
 * overwrite configuration in your local configuration file
 * local/config/config.inc.php. See tools/config.inc.php as an example.
 *
 * Why having some parameters in config table and others in
 * config_*.inc.php? Modifying config_*.inc.php is a "hard" task for low
 * skilled users, they need a GUI for this : admin/configuration. But only
 * parameters that might be modified by low skilled users are in config
 * table, other parameters are in config_*.inc.php
