Wow! That's a huge loss of usability to me :( I want to compare images, 
not sets of images. I don't have complete sets to start from and I don't 
want to see a report that a thousand things are missing. It also sounds 
from that that it won't be able to compare profiles because it doesn't 
know about them. :(

I'm trying to sync up the profiles work from b60 level to b65 and I just 
got the images target to build again, so now I want to check that the 
jdk and jre images produced has the same contents compared to my b60 
build, before trying to make the profile images work again.

We also wanted to use this tool to compare a new build JDK with an old 
build JDK. But we really want to be able to work with individual images.
