-# Note 1: Poetry, Tox, and this project plugin all use pip under the hood for package
-#         installation. This means that even though we are creating up to eight venvs
-#         during a given CI run they all share the same download cache.
-# Note 2: The "VIRTUAL_ENV=$CI_VENV" prefix on the poetry commands below sets the venv
-#         that poetry will use for operations. There is no CLI flag for poetry that
-#         directs it to use a given environment, but if it finds itself in an existing
-#         environment it will use it and skip environment creation.
