 * Among other things, it contains the advanced authentication work.
 *
 * Order of sections for common.inc.php:
 *
 * the authentication libraries must be before the connection to db
 *
 * ... so the required order is:
 *
 * LABEL_variables_init
 * - initialize some variables always needed
 * LABEL_parsing_config_file
 * - parsing of the configuration file
 * LABEL_loading_language_file
 * - loading language file
 * LABEL_setup_servers
 * - check and setup configured servers
 * LABEL_theme_setup
 * - setting up themes
 *
 * - load of MySQL extension (if necessary)
 * - loading of an authentication library
 * - db connection
 * - authentication work
