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)

Wonder if the versioned conflicts for perl-modules against some of those virtual packages could not be dropped by now. Most versioned conflicts for perl-base were added for Lenny, so those will probably be around for a while.

$ debtree --with-suggests --versioned-conflicts aptitude

Equivalent graph for debconf
