# submodules: Whether we should initialize and update

# clone_before: before which resources a cloning should
#               happen. This is releveant in combination
#               with submodules as the exec of submodules
#               requires the `cwd` and you might get a
#               dependency cycle if you manage $projectroot
#               somewhere else.
