I end up using TC a lot to manage many rules that have a few levels of parents and it can be hard to keep track of how everything relates so this tool just formats the Qdiscs and classes into an hierarchical format.

You can just use make install to put it in /usr/local/bin, or go build if you don't want to use my makefile and handle it yourself.

Turns this

[nick@fedora ~]$ tc qdisc show dev eth0
