+     "This package contains functions to compute the nonparametric
+@dfn{maximum likelihood estimator} (MLE) for the bivariate distribution of
+@code{(X,Y)}, when realizations of @code{(X,Y)} cannot be observed directly.
+To be more precise, we consider the situation where we observe a set of
+rectangles that are known to contain the unobservable realizations of (X,Y).
+We compute the MLE based on such a set of rectangles.  The methods can also be
+used for univariate censored data (see data set @code{cosmesis}), and for
+censored data with competing risks (see data set @code{menopause}).  The
+package also provides functions to visualize the observed data and the MLE.")
