How does this compare to qemu-img?
If I understand correctly, the main feature in comparison is that it
offers a mode that kind of combines qemu-img's 'convert -B' and
'rebase', i.e. convert with a target backing file, but making no
assumptions about the content of the target backing file. Is my
understanding correct?
