/**
 * Chamilo LMS
 *
 * 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 chamilo.install
