Filtering Collisions - how to?

I'm reading Programming Guide Ch12 - Physics and I'm slightly confused how to setup and use CategoryBitmask and CollisionBitmask to filter collisions properly.

Say, I have the following physics bodies:

Body player, dumb, edge, barrier, bonus, tile

• player can collide with dumb, edge and bonus
• dumb can collide with dumb, edge and barrier
• barrier can collide with dumb
• bonus can collide with player
• tile can collide with nothing

How to setup bitmasks and filter body collisions in such scenario?
