How to avoid sessions when parsing bbcode?

[orban]

I need to parse bbcode but I want to avoid any sessions.

To use class_bbcode.php you have to include global.php which includes init.php which starts a session.

require_once('./global.php');
require_once('./includes/class_bbcode.php');
$parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());

Is there any way to use the bbcode parser without starting the whole vB system? Or force the script to register as a guest.
