* - include of /conf/configuration.php;
* - include of several libraries: main_api, database, display, text, security;
* - selecting the main database;
* - include of language files.
*
* @package dokeos.include
* @todo isn't configuration.php renamed to configuration.inc.php yet?
* @todo use the $_configuration array for all the needed variables
* @todo remove the code that displays the button that links to the install page
* but use a redirect immediately. By doing so the $already_installed variable can be removed.
* @todo make it possible to enable / disable the tracking through the Dokeos config page.
