There is actually a huge functional difference between the two that you are missing here. A meta package defines its dependencies in full dependency syntax. This means you can specify versions, USE flag dependencies, make packages dependent on USE flags, etc. A package set is just a list of packages (potentially constrained by version. TTBOMK, there is no inclusion of any USE flag functionality in sets. Additionally, let's say you have a more complicated dependency like || ( A B ), I don't think there is a way to describe that in a package set at all. I'm not sure I see the merit in pushing for package sets in the bulk of cases for this reason. Maybe there is some scenario where package sets are a better option, but you haven't enumerated what that might be (and I'm not really interested in brainstorming until I come up with one, so I'll wait for one frmo someone else) Of course, my sets knowledge is a little limited compared to some people, so if something I've said about package sets is incorrect, please feel free to correct it. -- NP-Hardass
