+     "This package takes a list of p-values resulting from the simultaneous
+testing of many hypotheses and estimates their q-values and local @dfn{false
+discovery rate} (FDR) values.  The q-value of a test measures the proportion
+of false positives incurred when that particular test is called significant.
+The local FDR measures the posterior probability the null hypothesis is true
+given the test's p-value.  Various plots are automatically generated, allowing
+one to make sensible significance cut-offs.  The software can be applied to
+problems in genomics, brain imaging, astrophysics, and data mining.")
