* Short term
** Graphviz display code thoughts
The code for the --graph option is over two files: print_graph, and
graphviz. I believe this is because Bison used to also produce VCG graphs,
but since this is no longer true, maybe we could consider these files for
fusion.
Little effort factoring seems to have been given to factoring in these files,
and their print-xml and print counterpart. We would very much like to re-use
the pretty format of states from .output in the .dot
Also, the underscore in print_graph.[ch] isn't very fitting considering
the dashes in the other filenames.
** Variable names.
What should we name `variant' and `lex_symbol'?
