	# on a specific light docker container instead of using default GH-actions one.

	# Retrieve and use a light docker container on which ocaml 4.10 is installed
	# as a system compiler. This container also contains opam 2.1.

	# to `ocaml` with the container parameters

	- name: Update opam repository

	# Create a switch with the system compiler (no compilation needed).
	# And then, install external (no need for depext with opam 2.1) and libs deps.
	- run: opam switch create . ocaml-system --deps-only --ignore-constraints-on alt-ergo-lib,alt-ergo-parsers

	# Install the project packages
