+    (description
+     "This package provides a differential abundance analysis for the
+comparison of two or more conditions.  Useful for analyzing data from standard
+RNA-seq or meta-RNA-seq assays as well as selected and unselected values from
+in-vitro sequence selections.  Uses a Dirichlet-multinomial model to infer
+abundance from counts, optimized for three or more experimental replicates.
+The method infers biological and sampling variation to calculate the expected
+false discovery rate, given the variation, based on a Wilcoxon Rank Sum test
+and Welch's t-test, a Kruskal-Wallis test, a generalized linear model, or a
+correlation test.  All tests report p-values and Benjamini-Hochberg corrected
+p-values.  ALDEx2 also calculates expected standardized effect sizes for
+paired or unpaired study designs.")
