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?

Tim
