individually and combined. For instance, you can say
environment.systemPackages = [ pkgs.kde4.kdesdk.kcachegrind ];
for just kcachegrind, or
environment.systemPackages = [ pkgs.kde4.kdesdk ];
to get all of kdesdk. Everything can also be installed by name
through nix-env. (There is a name clash between the ColorSchemes
packages in kdeaccessibility and kdeartwork, though.)
