+to fit @dfn{generalized linear models} (GLMs) with multiple types of
+predictors via regularized maximum likelihood.  Next to the fitting
+procedure, following functionality is available:
+
+@itemize
+@item Selection of the regularization tuning parameter lambda using
+  three different approaches: in-sample, out-of-sample or using
+  cross-validation.
+@item S3 methods to handle the fitted object including visualization
