/**
==============================================================================
* 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. While we're busy developing we
* work in this one - large - separate file so not to disturb the other
* existing classes - the existing code remains working.
*
* This script uses PEAR QuickForm and QuickFormController classes.
*
* First version
* - ask for old version path
* - check version (1.6.x or 1.8.x, no others supported at the moment)
* - get settings from old version
* - perform necessary upgrade functions based on version
* Future improvements
* - ask user if she agrees to detected version (chance to cancel)
* - ability to do in-place upgrade
* - ability to let old databases remain and clone thelm for new install so
* Dokeos admins can have old and new version running side by side
*
* @package dokeos.install
