But there is no rrd files in those directories, this is were orcallator
puts its raw data. Are those the directory you are copying, or is that a
typo ?

I am looking at this, to see what I can do with it - I'll get back to the
list if I figure something out.

For information, what I am trying to do is to have each server/workstation
running orca to generate the rrd and png files, copy those on one web
server, and have orca generates the html files only on this box, without
wasting cpu time trying to re-generate the rrd and png files.
