description         a fast online learning tool
long_description    Vowpal Wabbit is the essence of speed in machine learning, able to \
                    learn from terafeature datasets with ease. Via parallel learning, \
                    it can exceed the throughput of any single machine network interface \
                    when doing linear learning, a first amongst learning algorithms.
