+through all possible subsets of z-scores to identify the subset of traits
+giving the best meta-analyzed z-score.  Further, it returns a p-value
+adjusting for the multiple-testing involved in the search.  It also allows for
+searching for the best combination of disease subtypes associated with each
+variant.")
