Yes, but that is TLMGR, and I am speaking of TeX !  In other
words, if I write \usepackage {keyval}, I would like /TeX/
to (a) look to see if I have keyval.cls locally; (b) if not,
look to see in which package/bundle/whatever "keyval" lives;
(c) fetch the p/b/w-h-y from CTAN; (d) un-p/b/w it into my
local TeXMF hierarchy; (e) continue as if nothing had happened
and the file had been local all the while.  It may sound
"pie in the sky", but isn't this exactly what a sane, reasonable,
TeX user would want to happen in the 21st century ?
