(synopsis "Generation of comparison functions from types")
(description "Generation of fast comparison functions from type expressions
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.")
