+    (description
+     "This package can do non-parametric bootstrap and permutation
+resampling-based multiple testing procedures (including empirical Bayes
+methods) for controlling the family-wise error rate (FWER), generalized
+family-wise error rate (gFWER), tail probability of the proportion of
+false positives (TPPFP), and false discovery rate (FDR).  Several choices
+of bootstrap-based null distribution are implemented (centered, centered
+and scaled, quantile-transformed).  Single-step and step-wise methods are
+available.  Tests based on a variety of T- and F-statistics (including
+T-statistics based on regression parameters from linear and survival models
+as well as those based on correlation parameters) are included.  When probing
+hypotheses with T-statistics, users may also select a potentially faster null
+distribution which is multivariate normal with mean zero and variance
+covariance matrix derived from the vector influence function.  Results are
+reported in terms of adjusted P-values, confidence regions and test statistic
+cutoffs.  The procedures are directly applicable to identifying differentially
+expressed genes in DNA microarray experiments.")
