Thanks.

It does, but the next sentence details the problem
with that description: nothing about `dependency',
for example (dunno whether there are other problems
with the columns description).

I know (and likely care) less about the package system
than you.  Neither of us is well placed, probably, to
help much in this regard.

I do appreciate your attempts to solicit strong doc
along with new developments.  The package system
slipped between the cracks to some extent in this
regard, I guessed.  A guess is that when a large
set of code gets developed outside Emacs first
it can get added to Emacs all at once, and the doc
isn't necessarily gone over with a fine-tooth comb,
in spite of your best efforts.

I agree that it would be great if Someone (TM) gave
the package.el doc some more attention.

Thank you.
