post-messages: [
"afl-persistent is installed, but since the current OCaml compiler does
not enable AFL instrumentation by default, most packages will not be
instrumented and fuzzing with afl-fuzz may not be effective.

To globally enable AFL instrumentation, create an OCaml switch like:

  opam switch create %{ocaml:version}%+afl ocaml-variants.%{ocaml:version}%+options ocaml-option-afl" {success & afl-available & !afl-always}

synopsis: "Use afl-fuzz in persistent mode"
description: """
afl-fuzz normally works by repeatedly fork()ing the program being
tested. using this package, you can run afl-fuzz in 'persistent mode',
which avoids repeated forking and is much faster."""
