# Hint: it really helps if queues in both directions are the same name,
# if you're, say, shaping multiple customers in both ways.
# Remember, the rules create state, and queueing applies to that state.
# So, if anything matches to queue "big", it'll look for "big" on each
# direction, and appear on the queue it goes out on.
# This way you'll get bi-directional shaping using just one rule.
#
# Remember, never trust anything you didn't test yourself first.
