    `*VERSION` can be used to derive version-specific rules and can be passed
    to the rules.

    The `VERSION`s and also the local `PATH` to the repo can be accessed in
    python libraries/binaries. By adding `@envoy_repo` to `deps` they become
    importable through the `envoy_repo` namespace.

    As the `PATH` is local to the machine, it is generally only useful for
    jobs that will run locally.

    This can be useful, for example, for bazel run jobs to run bazel queries that cannot be run
    within the constraints of a `genquery`, or that otherwise need access to the repository
    files.
