Erg. So if I say to the machine, "emerge unmerge C", it will
refuse to do so? That can't be what you mean.

What Charles said a minute ago makes sense (where A<---B ==
"Package B will not function without package A"):



If I say, "emerge unmerge B", what should happen?

Clearly A should go, because it won't work without B.

Less clearly, but still desirable IMO, C should go, because
nothing on the system is now using it. However, folks on
a slow link might want C to stick around, because they
might have only uninstalled B in order to install
WhizBangBReplacement (in which case they want A to stay
to, and so shouldn't be using reverse dependencies

And clearly, too, D must stay, because Q won't work
without it.

I think I've got it :-)
