-** erroneous test
-src/complains.c changed the output of errors (prefixes), but the m4 macros
-have not been changed to reflect this change.
-Fix the message "an identifier expected" (m4) in tests/input.at.
+** 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.

-A stray $ is a warning in the actions, but an error in the epilogue.
-IMHO, it should not even be a warning in the epilogue.

 Get rid of it.  The original idea is nice, but actually it makes
 the code harder to follow, and uselessly different from the other
 skeletons.
