+     "This package provides functions and data sets for actuarial science:
+modeling of loss distributions; risk theory and ruin theory; simulation of
+compound models, discrete mixtures and compound hierarchical models;
+credibility theory.  It boasts support for many additional probability
+distributions to model insurance loss amounts and loss frequency: 19
+continuous heavy tailed distributions; the Poisson-inverse Gaussian discrete
+distribution; zero-truncated and zero-modified extensions of the standard
+discrete distributions.  It also supports phase-type distributions commonly
+used to compute ruin probabilities.")
