Dear Michael,

Appart from you saying
"this is how I think it would be a better overall tool."
I can not see any point in this discussion. (And in the rrdtool
developers version there is already a rrdupdate command which just
that functionality.)

But what I realy want to say is, that I am primarily interested in
things which make using rrdtool more simple, be it for graphing or data
collection. This mainly involves people sitting down at their
machine and writing code. Preferably after discussing their plan on
the developers mailinglist ... So if you have something to say or
contribute in this area lets hear it ...
