[pacman-dev] wanted: script to list uninstalled optdepends and packages that need them

Hi all, I had a thought today that a script to list package that are optdepends but not installed could be quite useful... I have not written one, but thought it would be good for pacman-contrib if someone wanted to contribute. Example output: tk - optional for: ruby - for Ruby/TK python - for IDLE, pynche and modulator fakeroot - optional for: pacman - for makepkg usage as normal user So get script writing! Preferably in bash or perl (which the current scripts use). Allan
