Pavan, I guess part of the documentation difficulty is in that Mahout
Samsara environment is only used for "training" but external components are
used for "scoring". So it is not 100% end-to-end Mahout solution to
document.

Pat, it would be nice though to put some of your docs on to Mahout site
though, what you think? They will be bound by Apache ICLA though after that
(meaning anyone can cut-and-paste it and put it in their books, with or --
in practice -- without any attribution).
