telling apt-get not to remove potentially useful packages?

[Vincent Lefevre <vincent@vinc17.net>]

How can I tell apt-get not to break the system by removing
potentially useful packages?

Note: removing packages like orphaned libraries or packages whose
features are provided by other installed packages (e.g. due to
rename or merge) is fine.
