 * This is the index file displayed when a user is logged in on Chamilo.

 * It displays:
 * - personal course list
 * - menu bar
 * Search for CONFIGURATION parameters to modify settings
 * @package chamilo.main
 * @todo Shouldn't the SCRIPTVAL_ and CONFVAL_ constant be moved to the config page? Has anybody any idea what the are used for?
 *       If these are really configuration settings then we can add those to the dokeos config settings.
 * @todo check for duplication of functions with index.php (user_portal.php is orginally a copy of index.php)
 * @todo display_digest, shouldn't this be removed and be made into an extension?
