Hi - I��m wondering how you best remove packages in the image to reclaim space?

I am a bit confused because I see 2 package systems MCPackage and RPackage? And I see 2 different ways of removing things:

(MCPackage named: name) unload

(RPackage organizer packageNamed: name) unregister

So which is the correct one to use (or are they the same?).

I��ve tried both, but then when I save my image (headless in a script) - it doesn��t seem to make any difference in image size. So I��m also wondering if there is an extra step to forcing size reduction. I have tried:

3 timesRepeat: [
    Smalltalk garbageCollect.
    Smalltalk cleanOutUndeclared.
    Smalltalk fixObsoleteReferences].

Which is what I saw in some ImageCleaner tool, but again I don��t see any image size difference, which makes me wonder if I��m doing the wrong thing or missing a step?
