Arch Linux

Hi, I'd like to propose a feature to pacman/makepkg, allow users to create new meta-packages quickly.
Just let them define name,[description],and dependencies.

I imagine something like:
$pacman --meta myNvidia --desc "local NV install with openCL" --depends nvidia, opencl, someother<=1.3.37

which would create a PKGBUILD with appropriate (name,desc,depends, provides,conflicts) fields, download deps, call makepkg, pacman -U the meta-package.

Use-cases:

#1 no more forgotten opt-depends

disadvantage of today's optdepends is they are installed as explicit, so when i go through my list of packages to removed unused ones, I usually wonder what that lib/pkg is good for there. Meta pkg would handle this gratefully.

#2 work projects

I tend to work on several projects, where each requires specific apps for work, so I install them, when the project is over, I would like to wipe them off, but usually forget which were those.

$pacman --meta midi --desc "computer generated music" --depends abcmidi,mp32midi,dino


I think I could implement this in shell, but dont have enough pacman knowledge to do it in pacman itself.

What do you think about the idea and design?
I believe the implementation part shouldnt be too complex, as all tools are already in place, just to hook them up appropriately.

Cheers, Mark
