+    (description "The Tweedie compound Poisson distribution is a mixture of a
+degenerate distribution at the origin and a continuous distribution on the positive
+real line.  It has been applied in a wide range of fields in which continuous data
+with exact zeros regularly arise.  The cplm package provides likelihood based and
+Bayesian procedures for fitting common Tweedie compound Poisson linear models.
+In particular, models with hierarchical structures or extra zero inflation can be
+handled.  Further, the package implements the Gini index based on an ordered version
+of the Lorenz curve as a robust model comparison tool involving zero-inflated and
+highly skewed distributions.")
