    Ces constantes sont définies chacune dans le index.php page:

    /*
 * -------------------------------------------------------------------
 *  Now that we know the path, set the main path constants
 * -------------------------------------------------------------------
 */
    //The name of THIS file
    define('SELF', pathinfo(__FILE__, PATHINFO_BASENAME));

    //The PHP file extension
    //this global constant is deprecated.
    define('EXT', '.php');

    //Path to the system folder
    define('BASEPATH', str_replace("\\", "/", $system_path));

    //Path to the front controller (this file)
    define('FCPATH', str_replace(SELF, '', __FILE__));

    //Name of the "system folder"
    define('SYSDIR', trim(strrchr(trim(BASEPATH, '/'), '/'), '/'));


    //The path to the "application" folder
    if (is_dir($application_folder))
    {
            define('APPPATH', $application_folder.'/');
    }
    else
    {
            if ( ! is_dir(BASEPATH.$application_folder.'/'))
            {
                    exit("Your application folder path does not appear to be set correctly. Please open the following file and correct this: ".SELF);
            }

            define('APPPATH', BASEPATH.$application_folder.'/');
    }
