User Role Management

hi there,

I’m using Yii user management (YUM) extension, but I want to ask are there already included user-role management?

In YUM I found there are modules which help to manage user role, but I didn’t find out the user-role management layout! because they said YUM has included RBAC and ACL (I could not find out)

And now, after I insert permission, action, role, user, user_role’s data, do I create the manage page for my own purposes? I mean, I need to set in beforeAction in each controller to identify the user role?

ps: is there any document in detail for YUM :)
