Package: apt
Version: 0.5.4
Severity: wishlist
Tags: patch
apt-cache should have a reverse depends and a reverse build depends
action. it should include the functionality of apt-rdepends.
attached is a patch which adds a reverse depends action as well as an
installed flag, so you can check reverse depends and depends within
the context of your own machine.
i plan to add the build depends and build rdepends in the near
future.
