* In this file we're working on a well-organised upgrade script to
* upgrade directly from Dokeos 1.6.x to Dokeos 1.8.3

* For this upgrade we assume there is an old_dokeos directory and the new
* software is in a new_dokeos directory.
*
* This script uses PEAR QuickForm and QuickFormController classes.
