          Args:
              destdir (str): A local directory on disk into which the contents of
                  this MAR file will be extracted. Required parent directories
                  will be created as necessary.
              decompress (obj, optional): Controls whether files are decompressed
                  when extracted. Must be one of 'auto' or None. Defaults to
                  'auto'.
