  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.
