+     "The method implemented in this package performs bottom-up hierarchical
+clustering, using a Dirichlet Process (infinite mixture) to model uncertainty
+in the data and Bayesian model selection to decide at each step which clusters
+to merge.  This avoids several limitations of traditional methods, for example
+how many clusters there should be and how to choose a principled distance
+metric.  This implementation accepts multinomial (i.e. discrete, with 2+
+categories) or time-series data.  This version also includes a randomised
+algorithm which is more efficient for larger data sets.")
