28 * This is the MAIN DOCUMENT of the TypoScript driven standard front-end (from the "cms" extension)
29 * Basically put this is the "index.php" script which all requests for TYPO3 delivered pages goes to in the frontend (the website)
30 * The script configures constants, includes libraries and does a little logic here and there in order to instantiate the right classes to create the webpage.
31 * All the real data processing goes on in the "tslib/" classes which this script will include and use as needed.
32 *
33 * On UNIX: You should create a symlink to this file from the directory from which you want your TYPO3 website to run (which is ../)
34 * ln -s tslib/index_ts.php index.php

36 * On Windows this file should copied to "index.php" in your website root (which is ../)
