The example at
<URL:http://caml.inria.fr/resources/doc/guides/format.en.html#hov-boxes>
shows a major difference in the output of packing versus structural hov
boxes.  However, in my experiments I cannot achieve the output this
example assigns to "packing" boxes.  (OCaml 3.12)

My examples from the REPL are below.  Would someone be able to tell me
what I am doing incorrectly?

# Format.printf "@[<hv 2>(---@\n@[<hv 2>(---@\n@[<hv 2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
# Format.printf "@[<hov 2>(---@\n@[<hov 2>(---@\n@[<hov 2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
# Format.printf "@[<2>(---@\n@[<2>(---@\n@[<2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
# Format.printf "@[<b 2>(---@\n@[<b 2>(---@\n@[<b 2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()

I have no idea what you're doing wrong, but I can suggest you try 
easy-format (http://mjambon.com/easy-format.html) which lets you choose 
and customize various indentation styles.

Hi, I think he is trying to explain the difference:

let s = "--------------------------" in Format.fprintf 
Format.std_formatter "@[<hov1>(%s@[<hov1>(%s@[<hov1>(%s@,)@]@,)@]@,)@]" 
s s s;;
let s = "--------------------------" in Format.fprintf 
Format.std_formatter "@[<hov1>(%s@[<hov1>(%s@[<hov1>(%s@,)@]@,)@]@,)@]" 
s s s;;
(--------------------------(--------------------------(--------------------------
                                                        )))- : unit = ()
# let s = "--------------------------" in Format.fprintf 
Format.std_formatter "@[<1>(%s@[<1>(%s@[<1>(%s@,)@]@,)@]@,)@]" s s s;;
let s = "--------------------------" in Format.fprintf 
Format.std_formatter "@[<1>(%s@[<1>(%s@[<1>(%s@,)@]@,)@]@,)@]" s s s;;
(--------------------------(--------------------------(--------------------------
                                                        )
                             )
  )- : unit = ()
