Ott takes as input a definition of a language syntax and semantics, in a concise
and readable ASCII notation that is close to what one would write in informal
mathematics. It can then generate a Coq version of the definition, which requires
this library.

Dry install with the current Coq version:

Command
opam install -y --show-action coq-ott.0.31 coq.8.17.1
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.17.1).
[ERROR] Package conflict!
  * No agreement on the version of ocaml:
    - (invariant) -> ocaml-base-compiler >= 5.1.1 -> ocaml = 5.1.1
    - coq-ott = 0.31 -> coq < 8.12~ -> ocaml < 4.02.0
    You can temporarily relax the switch invariant with `--update-invariant'

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
