When I started with TC, I also tried the cbq.init script. It's very limited
in what you can do. Once you know TC, you will realize that cbq.init is too
limited and that's doing some things wrong because the situation is much more
complicated.
An example. You can select tbf as a leaf qfdisc for a cbq class. But the
qdisc is allready shaping, so attaching a tbf qdisc is not needed. It can
disturb the setup and can result in some strange behaviour.
