      Args:
          argv: Each item of argv will be treated as a separate
              module with potential arguments
              each item may be a string or a sequence of strings.
              If a given argument is a string, then treat string as
              shell arguments and split accordingly.
              If the given argument is a tuple or list, then assume
              that the given arguments are already parsed.
              The first item of each argument should be a module or module path
