Hello David,

> TL;DR for installing Menhir on OCaml 4.02-4.06 using opam, you don't need to do anything.

Thanks for your prompt reply, which sounds reassuring!

However, attempting to install dune 2.2.0 on a pre-4.07 switch
(for instance, 4.02.3) results in the following failure:

   $ opam install dune.2.2.0
   The following dependencies couldn't be met:
     - dune → ocaml >= 4.07 → ocaml-variants >= 4.07.0
         conflict with the base packages of this switch
     - dune → ocaml >= 4.07 → ocaml-system >= 4.07.0
         unmet availability conditions, e.g. sys-ocaml-version = "4.07.0"
     - dune → ocaml >= 4.07 → ocaml-base-compiler >= 4.07.0
         base of this switch (use `--unlock-base' to force)

I have run "opam update" first. Is there something else I should do
to convince opam that it is possible to install dune?
