code: ArgumentsBuilder intersperse(String param, List<String> values) {
          if (values != null) {
              for (String value : values) {
                  args.add(param);
                  args.add(value);

      }
docs: Adds a parameter that takes a value for each value in a list.
  For example, <code>intersperse("--foo", Arrays.asList("a", "b"))</code>
  will add <code>--foo a --foo b</code> to the argument list.
