+and definitions. Ppx_compare is a ppx rewriter that derives comparison functions
+from type representations. The scaffolded functions are usually much faster
+than ocaml's Pervasives.compare. Scaffolding functions also gives you more
+flexibility by allowing you to override them for a specific type and more safety
+by making sure that you only compare comparable values.")
