+It was designed to meta-analyze gene-level association tests for binary trait.
+While rareMETALS offers a near-complete solution for meta-analysis of
+gene-level tests for quantitative trait, it does not offer the optimal
+solution for binary trait.  The package rareMETALS2 offers improved features
+for analyzing gene-level association tests in meta-analyses for binary
+trait.")
