+     "The purpose of this package is to identify traits in a dataset that can
+separate groups.  This is done on two levels.  First, clustering is performed,
+using an implementation of sparse K-means.  Secondly, the generated clusters
+are used to predict outcomes of groups of individuals based on their
+distribution of observations in the different clusters.  As certain clusters
+with separating information will be identified, and these clusters are defined
+by a sparse number of variables, this method can reduce the complexity of
+data, to only emphasize the data that actually matters.")
