+     "This package provides tools for fitting possibly high dimensional
+penalized regression models.  The penalty structure can be any combination of
+an L1 penalty (lasso and fused lasso), an L2 penalty (ridge) and a positivity
+constraint on the regression coefficients.  The supported regression models
+are linear, logistic and Poisson regression and the Cox Proportional Hazards
+model.  Cross-validation routines allow optimization of the tuning
+parameters.")
