+     "This is a package for regression modeling, testing, estimation,
+validation, graphics, prediction, and typesetting by storing enhanced model
+design attributes in the fit.  The rms package is a collection of functions
+that assist with and streamline modeling.  It also contains functions for
+binary and ordinal logistic regression models, ordinal models for continuous Y
+with a variety of distribution families, and the Buckley-James multiple
+regression model for right-censored responses, and implements penalized
+maximum likelihood estimation for logistic and ordinary linear models.  The
+package works with almost any regression model, but it was especially written
+to work with binary or ordinal regression models, Cox regression, accelerated
+failure time models, ordinary linear models, the Buckley-James model,
+generalized least squares for serially or spatially correlated observations,
+generalized linear models, and quantile regression.")
