and its not that obvious to me how to do that. Especially on short notice
which is my view of we're dealing with here.

There is another concern that I have. In spite of all of the above, the
part of the documentation which I think needs the most work is
"Archive Implementation". This is fairly complicated undertaking. I
do suspect that it will result in a refinement of "Archive Concept" as
this task progresses.
