+ (description
+ "This package provides an exact Goodness-of-Fit test for
+multinomial data with fixed probabilities. It can be used to
+determine whether a set of counts fits a given expected ratio. To see
+whether a set of observed counts fits an expectation, one can examine
+all possible outcomes with @code{xmulti()} or a random sample of them
+with @code{xmonte()} and find the probability of an observation
+deviating from the expectation by at least as much as the observed.
+As a measure of deviation from the expected, one can use the
+log-likelihood ratio, the multinomial probability, or the classic
+chi-square statistic. A histogram of the test statistic can also be
+plotted and compared with the asymptotic curve.")
