Hello!
It seems my mail system has missed the mail message from Tobi,
so I picked up the next message in thread to answer.

I just needed current RRD to generate proper SVG right now
therefore I've created that patch.

I'll have a look at it on Monday.
BTW: rrdfraph always outputs something to stdout/stderr.
Even if the picture generation succeeds, it prints image size
to stdout. This makes rrdgraph usage as a cron job rather an ugly
thing. I created another patch to implement "-q" "--quiet" option.
But for 1.2.x version it seems bad, as rrdtool has mode-specific
command arguments parsing, and the offending printf() is done
in global part. There is no global place to store flags. I had
to add "flags" field to global context structure, and this way
was able to pass "-q" flag from mode-specific to global code of
rrdtool.
This implementation seems ugly, and the right idea,
I suppose, is this: Pass some structure like "request mode" from main()
to all mode-specific code parts. It would allow to pass full status
information back to main().
If I try to implement this option in 1.3.x, what is the
right way to do it?
Bye. Alex.
