description: """
MetaCoq is a meta-programming framework for Coq.
The PCUIC module provides a cleaned-up specification of Coq's typing algorithm along
with a certified typechecker for it. This module includes the standard metatheory of
PCUIC: Weakening, Substitution, Confluence and Subject Reduction are proven here.

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-metacoq-pcuic.1.0~beta2+8.11 coq.8.12.0
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.12.0).
The following dependencies couldn't be met:
  - coq-metacoq-pcuic -> coq-metacoq-template = 1.0~beta2+8.11 -> coq < 8.12~ -> ocaml < 4.06.0
      base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
  - No available version of coq satisfies the constraints
No solution found, exiting

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

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-metacoq-pcuic.1.0~beta2+8.11
