+    (description
+     "Fit generalized linear models with binomial responses using either an
+adjusted-score approach to bias reduction or maximum penalized likelihood
+where penalization is by Jeffreys invariant prior.  These procedures return
+estimates with improved frequentist properties (bias, mean squared error) that
+are always finite even in cases where the maximum likelihood estimates are
+infinite (data separation).  Fitting takes place by fitting generalized linear
+models on iteratively updated pseudo-data.  The interface is essentially the
+same as @code{glm}.  More flexibility is provided by the fact that custom
+pseudo-data representations can be specified and used for model fitting.
+Functions are provided for the construction of confidence intervals for the
+reduced-bias estimates.")
