Richard Hughes: Every distro re-invents the same type of package-management tools, and generally does it badly. Package management front ends are nearly always badly localized and translated as they are distro specific. Fedora has pup and pirut, Ubuntu has gnome-app-install and update-manager, and Suse has libzypp command line tools and the zen updater. The other distros basically throw some kind of GUI on top of the package tool rather than look at the use-cases and user interaction studies.
