  # from other modules (thus have a .fixtures.yaml file),
  # read the contents of the fixtures file and create a
  # one-level dependency tree. It could be debatable if we should
  # include higher order, indirect dependencies (if module C depends on module
  # B that depends on module A, should we add it to the dependencies of C?),
  # but we chose not to go that way as each module should just care about the
  # interfaces it uses directly.
