Display. Visualization of Caml values. Jean-Christophe Filliātre.
=================================================================

This little piece of code displays the internal representation of Caml values.
It produces a graph as an ASCII file, in a format suitable for the `dot' tool
(freely available at http://www.research.att.com/sw/tools/graphviz/).

This module exports a function `display : string -> 'a -> unit' which takes
as arguments the name of the file to produce and the Caml value to display.
One the file is written, say foo.dot, a PostScript file can be produced
with the command

	dot -Tps foo.dot -o foo.ps

(the `dot' tool supports other output languages; see the manual page for dot)
