class_docstr: Dependency settings for the remote function.
  
  Instructs the runtime environment script on how to handle dependencies.
  If ``dependency_file`` is set, the runtime environment script will attempt
  to install the dependencies. If ``dependency_file`` is not set, the runtime
  environment script will assume no dependencies are required.
