Aptitude is text-based, and can be run from a terminal. A flexible syntax to match packages in a mutt-like fashion. You can mark packages as "automatically installed" and "manually installed" to allow packages to be removed when they are no longer needed (feature also available in Apt since a few Debian releases). Preview of actions to be performed with different colors marking different actions. Interactively retrieve and display all available Debian packages' changelogs. Score-based dependency solver that is more suitable to interactive dependency resolution with additional hints such as "I don’t want this part of the answer but keep that other part for your next attempt." Apt's dependency solver, on the other hand, is optimized for quick solutions.
