synopsis: "The Chou, Gao and Zhang area method"
description: """
This contribution is the implementation of the Chou, Gao and Zhang's area method decision procedure for euclidean plane geometry.
This development contains a partial formalization of the book "Machine Proofs in Geometry, Automated Production of Readable Proofs for Geometry Theorems" by Chou, Gao and Zhang.
The examples shown automatically (there are more than 100 examples) includes the Ceva, Desargues, Menelaus, Pascal, Centroïd, Pappus, Gauss line, Euler line, Napoleon theorems.

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-area-method.8.5.0 coq.dev
Return code
5120
Output
[NOTE] Package coq is already installed (current version is dev).
The following dependencies couldn't be met:
  - coq-area-method -> coq < 8.6~ -> 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-area-method.8.5.0
