28 * TYPO3 Backend initialization
29 *
30 * This script is called by every backend script.
31 * The script authenticates the backend user.
32 * In addition this script also initializes the database and other stuff by including the script localconf.php
33 *
34 * IMPORTANT:
35 * This script exits if no user is logged in!
36 * If you want the script to return even if no user is logged in,
37 * you must define the constant TYPO3_PROCEED_IF_NO_USER=1
38 * before you include this script.
39 *
40 *
41 * This script does the following:
42 * - extracts and defines path's
43 * - includes certain libraries
44 * - authenticates the user
45 * - sets the configuration values (localconf.php)
46 * - includes tables.php that sets more values and possibly overrides others
47 * - load the groupdata for the user and set filemounts / webmounts
48 *
49 * For a detailed description of this script, the scope of constants and variables in it,
50 * please refer to the document "Inside TYPO3"
