+    (description
+     "iClusterPlus is developed for integrative clustering analysis of
+multi-type genomic data and is an enhanced version of iCluster proposed and
+developed by Shen, Olshen and Ladanyi (2009).  Multi-type genomic data arise
+from the experiments where biological samples (e.g. tumor samples) are
+analyzed by multiple techniques, for instance, @dfn{array comparative genomic
+hybridization} (aCGH), gene expression microarray, RNA-seq and DNA-seq, and so
+on.  In the iClusterPlus model, binary observations such as somatic mutation
+are modeled as Binomial processes; categorical observations such as copy
+number states are realizations of Multinomial random variables; counts are
+modeled as Poisson random processes; and continuous measures are modeled by
+Gaussian distributions.")
