- /**
- * TYPO3 Backend initialization
- *
- * This script is called by every backend script.
- * The script authenticates the backend user.
- * In addition this script also initializes the database and other stuff by including the script localconf.php
- *
- * IMPORTANT:
- * This script exits if no user is logged in!
- * If you want the script to return even if no user is logged in,
- * you must define the constant TYPO3_PROCEED_IF_NO_USER=1
- * before you include this script.
- *
- *
- * This script does the following:
- * - extracts and defines path's
- * - includes certain libraries
- * - authenticates the user
- * - sets the configuration values (localconf.php)
- * - includes tables.php that sets more values and possibly overrides others
- * - load the groupdata for the user and set filemounts / webmounts
- *
- * For a detailed description of this script, the scope of constants and variables in it,
- * please refer to the document "Inside TYPO3"
