David,
this doesn't seem to exist and I stumbled over the same requirement
a few years ago and back then I hacked up a little bash script which
does exactly that - using the output from rrdtool info.
It doesn't support the full rrd create syntax - especially support
for the COMPUTE DS-type and the Aberrant Behavior Detection has
been left out because it was more complex to add and I don't need it.
Feel free to add the missing functionality if you want.
The script is attached for everybodies convenience.
(if it makes it through the mailing list)
Of course it is provided as-is and with no support.
Use on your own risk.
