+     "This package extends the @code{fitdistr} function of the MASS package
+with several functions to help the fit of a parametric distribution to
+non-censored or censored data.  Censored data may contain left-censored,
+right-censored and interval-censored values, with several lower and upper
+bounds.  In addition to @dfn{maximum likelihood estimation} (MLE), the package
+provides moment matching (MME), quantile matching (QME) and maximum
+goodness-of-fit estimation (MGE) methods (available only for non-censored
+data).  Weighted versions of MLE, MME and QME are available.")
