+* Updates the Dokeos files from version 1.8.3 to version 1.8.4
+* This script operates only in the case of an update, and only to change the
+* active version number (and other things that might need a change) in the
+* current configuration file.
+* As of 1.8.4, the Dokeos version has been added to configuration.php to
+* allow for edition (inc/conf is one of the directories that needs write
+* permissions on upgrade).
+* Being in configuration.php, it benefits from the configuration.dist.php
+* advantages that a new version doesn't overwrite it, thus letting the old
+* version be available until the end of the installation. 
+* @package dokeos.install
