Yes. I have these .tex files as well. Much beter than scanning through the
source code...

"ip" is kind of easy to follow (maybe because I already know what I'm looking
for) but when it comes down to "tc", my head spins. Take the following (easy)
example:

tc class add dev eth1 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 1Mbit \
allot 1514 cell 8 weight 100Kbit prio 3 maxburst 20 avpkt 1000 split 1:0 \
defmap c0

A small note on all these options would have saved me a lot of guess-work.

But anyway, don't take me wrong. I think that iproute2 is one of the coolest
networking tools I've ever seen.
