But what exactly does "tlmgr update --list" do ?
Does it compare the actual files I have in my
TeX hierarchy with those on CTAN, or does it
compare their modification dates ?  Can it
detect if I have accidentally deleted one
(or many) ?  Will it report new packages,
or changed packages, or both, and so on.
