[Wikitech-l] how to use Group class

Hi all, I am working something about the access right control with mediawiki :

- MediaWiki http://www.mediawiki.org/: 1.5.7 - PHP http://www.php.net/: 5.0.4 (apache2handler) - MySQL http://www.mysql.com/: 4.1.13-nt

During the work I found a useful class "Group" in Group.php. It seems that this class is never used. In order to use this class I have to make a corresponding database, but I don't know what is the schema of the database. According to the class Group the following columns are necessary: name id description dataLoaded rights

Are these columns complete? Which data types are used for the corresponding columns?

Any answers are appreciated.

Thanks a lot
