Vowpal Wabbit is a machine learning system which pushes the frontier of machine learning with techniques such as online, hashing, allreduce, reductions, learning2search, active, and interactive learning.
1) no binary classification code in boosting
2) boosting below binary in reduction stack
3) breaking change (since old "--boosting n" becomes "--boosting n --binary")
