I don't really get the difference between the two as impl. = today.
What can PKG_INSTALL_MASK do that INSTALL_MASK can't(or vice versa)?

What I undersood is that=C2= =A0 PKG_INSTALL_MASK will make smaller binary tbz file, and
INSTALL_MAS= K will at install time, mask files, so the tbz will have all files in it.

Yeah, it is a bit much :) I either case it would be nice if one
could group several bianry pkgs into one that qmerge can install. Is that p= ossible?
