I haven't used weka in anger, but intended to in a few months and
hopefully via kepler.... My understanding was that YALE superceeded
Weka and YALE has been renamed RapidMiner.  IIRC RapidMiner is still
open source.  Did I misunderstand the ancestry and Rapid Miner doesn't
replace Weka?  Is there some other reason for not building on top of
RapidMiner?

Cheers
