description         A scalable machine learning library that supports large data sets

long_description    Mahout is a scalable machine learning library that implements many \

                    different approaches to machine learning. \

                    The project currently contains implementations of algorithms for \

                    classification, clustering, genetic programming and collaborative \

                    filtering, all enabled to scale by leveraging the power of Hadoop's \

                    Map-Reduce (http://hadoop.apache.org) implementation.
