+** 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.

-Do some people use YYPURE, YYLSP_NEEDED like we do in the test suite?
-They should not: it is not documented.  But if they need to, let's
-find something clean (not like YYLSP_NEEDED...).

-parser") refers to the current `output' format.

-* BTYacc
-See if we can integrate backtracking in Bison.  Charles-Henri de
-Boysson <de-boy_c@epita.fr> has been working on this, but never gave
-the results.
-
-Vadim Maslow, the maintainer of BTYacc was once contacted.  Adjusting
-the Bison grammar parser will be needed to support some extra BTYacc
-features.  This is less urgent.
-
-** Keeping the conflicted actions
-First, analyze the differences between byacc and btyacc (I'm referring
-to the executables).  Find where the conflicts are preserved.
-
-** Compare with the GLR tables
-See how isomorphic the way BTYacc and the way the GLR adjustments in
-Bison are compatible.  *As much as possible* one should try to use the
-same implementation in the Bison executables.  I insist: it should be
-very feasible to use the very same conflict tables.

-** Adjust the skeletons
-Import the skeletons for C and C++.
