  29 #
  30 # The options are, available both in single and double-dash versions
  31 #
  32 #   -b, -become    command to run on enter/pick, where `{}` is picked line,
  33 #                  and `{n}` is the picked line's nth items; also disallows
  34 #                  picking multiple items
  35 #   -h, -help      show this help message
  36 #   -m, -many      allow picking multiple items (+m disallows that)
  37 #   -s, -single    disallow picking multiple items (also available as +m)
