The tools can be run inside Coq, thus making them available for proof by reflection, and the code can also be extracted and connected to a yacc-based parser, thanks to the use of a functor parameterized by a module type of strings. A hand-written parser is also provided in Coq, but there are no proofs associated.

Dry install with the current Coq version:
opam install -y --show-action coq-semantics.8.14.0 coq.8.7.1+2
[NOTE] Package coq is already installed (current version is 8.7.1+2). The following dependencies couldn't be met: - coq-semantics -> coq >= 8.10 -> ocaml >= 4.09.0 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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-semantics.8.14.0
