/**
==============================================================================
* Updates the Dokeos files from an older version
* IMPORTANT: This script has to be included by install/index.php and update_courses.php
* Updates the Dokeos files from version 1.6.x to version 1.8.0
* IMPORTANT: This script has to be included by install/index.php or
* update_courses.php
*
* DOKEOS_INSTALL is defined in the install/index.php
* DOKEOS_COURSE_UPDATE is defined in update_courses.php
* DOKEOS_INSTALL is defined in the install/index.php (means that we are in
* the regular upgrade process)
*
* When DOKEOS_INSTALL or DOKEOS_COURSE_UPDATE is defined, do for every course:
* - remove the .htaccess in the document folder
* - remove the index.php in the group folder
* - write a new group/index.php file, make it an empty html file
* - remove the index.php of the course folder
* - write a new index.php file in the course folder, with some settings
* - create a 'temp' directory in the course folder
* - move the course folder inside the courses folder of the new Dokeos installation
* - move the group documents from the group folder to the document folder,
* keeping subfolders intact
* - stores all documents inside the database (document and item_property tables)
* - remove the visibility field from the document table
* - update the item properties of the group documents
* DOKEOS_COURSE_UPDATE is defined in update_courses.php (means we are
* executing update_courses.php to update courses separately)
*
* Additionally, when DOKEOS_INSTALL is defined
* - write a config file, configuration.php, with important settings
* - write a .htaccess file (with instructions for Apache) in the courses directory
* - remove the new main/upload/users directory and rename the main/img/users
* directory of the old version to main/upload/users
* - rename the old configuration.php to configuration.php.old,
* or if this fails delete the old configuration.php
* When DOKEOS_INSTALL or DOKEOS_COURSE_UPDATE are defined, do for every course:
* - create a new set of directories that reflect the new tools offered by 1.8
* - record an item_property for each directory added
*
* @package dokeos.install
