[otrs] OTRS 1.3 user - queue permission configurations

Hi Everyone, The documentation of otrs 1.3, permissions [1] states "You will be able to handle different groups of users with different permissions (e. g. only read ticket in a queue or one group should not have ro/rw access to a queue)." It is unclear to me how to implement those permissions. I would like to create group of "viewers" that would have read only permissions on certain queues, can this be implemented with the 1.3 version and if so please explain further. I've looked at the Config.pm file and haven't found any such option in the code. Thank you for your help, Maxim.
