Several of us use Debian GNU/Linux and among other features we have all appreciated the way Debian software package dependencies are calculated to give us astable package. At gnowledge.org we harvested the data from the packages.tgz file of Debian 4.0 and created a program that graphically displays the dependencies, called dependency maps. Search for your favorite package and see how dependent a software is on other packages.
