+pair of two-group differential expression analysis comparisons show a level of
+agreement that is greater than expected if the group labels for each two-group
+comparison are randomly assigned.  The agreement is evaluated for the entire
+transcriptome and (optionally) for a collection of pre-defined gene-sets.
+Additionally, the procedure performs permutation-based differential expression
+and meta analysis at both gene and gene-set levels of the data from each
+experiment.")
