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