/**
 *                           configuration page
 *
 * Set configuration parameters that are not in the table config. In the
 * application, configuration parameters are considered in the same way
 * 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
 * config_local.inc.php. See tools/config_local.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

//
//  - date_available : the date of the adding to the gallery
//  - file : the name of the file
//  - id : element identifier
//  - date_creation : date of element creation
//
// Once you've chosen which field(s) to use for ordering, you must chose the
// ascending or descending order for each field.  examples :
//
// 1. $conf['order_by'] = " order by date_available desc, file asc";
//    will order pictures by date_available descending & by filename ascending
//
// 2. $conf['order_by'] = " order by file asc";
