For instant satisfaction perform these commands (assumes debian, perhaps your package manager does an output of packes in dotty?)



apt-get install graphviz
apt-cache dotty iproute > iproute.dot
dotty -Tpng -oiproute.png iproute.dot

And it will output a png file with the relation of iproute to other packages on your system.

It will look like this:

The iproute.dot file on my system looks like this:
