How to show dots ?

[Drup]

At the moment, describe --dot uses xdot by default. I use it because the rendering is pretty, it has a nice and simple UI and it is widly available on linux plateforms (debian, ubuntu and arch all have it). Apparently, it's also available in brew (and even windows!). So either

• We stick with it (and add a conf-xdot to opam).
• We try to find an OCaml replacement.
• (optional) We try to add some auto-detection magic.

Potential OCaml replacements:

• The old one in ocamlgraph is broken, and the new one is not complete (and less pretty).
• ocamldot, haven't tested, depends on lablgtk

Not idea about the landscape but my gut feeling would be to find an html renderer and then open the file with xdg-open (linux) or open (osx) or ??? (windows) it.

xdot has a much nicer UI than plain html, especially as the graph get large.
