==============================================================================

|
* It is recommended that ALL dokeos scripts include this important file.
|
|
* This script manages
|
|
* - http get, post, post_files, session, server-vars extraction into global namespace;
|
|
* (which doesn't occur anymore when servertype config setting is set to test,
|
|
* and which will disappear completely in Dokeos 1.6.1)
|
|
* - 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.
|
|
*
