# Takes a submission zip and makes a tar file suitable for the sandbox
class SubmissionPackager
  # Packages a submitted ZIP of the given exercise into a TAR or a ZIP with tests
  # added from the clone (to ensure they haven't been tampered with).
  #
  # - zip_path must be the path to the submitted zip.
  # - return_file_path is the path to the file to be generated.
  # - extra_params are written as shell export statements into into .tmcparams.
  # - config options:
  #   - tests_from_stub: includes tests from the stub instead of the clone.
  #                      This effectively excludes hidden tests.
  #   - include_ide_files: includes IDE settings from the submission,
  #                        or from the clone if none in the submission
  #                        (as is usually the case).
  #   - no_tmc_run: does not include the tmc-run file
  #   - format: may be set to :zip to get a zip file. Defaults to :tar.
  #   - toplevel_dir_name: if present, the zip or tar is made such that
  #                        there is a toplevel directory with this name
