+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.
