debtree — package dependency graphs on steroids

Introduction

Example: aptitude

0. Graph from apt-cache (for comparison)
1. Basic graph (only hard dependencies and conflicts)
2. Basic graph with Recommends
3. Basic graph with Recommends and Suggests
4. Basic graph with Recommends and showing alternatives
5. Default graph (showing Recommends, alternatives and versions)
6. Default graph with Suggests
7. Default graph with Suggests and versioned Conflicts
8. Default graph (rotated)

This graph is roughly equivalent to:
$ debtree --no-recommends --no-versions --versioned-conflicts --rotate debconf

$ apt-cache dotty aptitude

Equivalent graph for debconf
