find something clean (not like YYLSP_NEEDED...).

* Documentation
Before releasing, make sure the documentation ("Understanding your
parser") refers to the current `output' format.
** vector
Move to using vector, drop stack.hh.
-** I18n
-Catch up with yacc.c.

** GLR
How would Paul like to display the conflicted actions? In particular,

keep $default? See the following point.
a sample text exhibiting the (LALR) ambiguity. See the paper from
DeRemer and Penello: they already provide the algorithm.
+** Statically check for potential ambiguities in GLR grammars. See

* Extensions
* Java, Fortran, etc.
-** Java
-
-There are a couple of proposed outputs:
-
-- BYACC/J
- which is based on Byacc.
- <http://troi.lincom-asg.com/~rjamison/byacc/>
-
-- Bison Java
- which is based on Bison.

-Sebastien Serrurier (serrur_s@epita.fr) is working on this: he is
-expected to contact the authors, design the output, and implement it
-into Bison.

* Coding system independence
Paul notes:
Show reductions.
* Broken options ?
-** %no-parser
** %token-table
** Skeleton strategy
-Must we keep %no-parser? %token-table?
+Must we keep %token-table?
* src/print_graph.c
Find the best graph parameters.
makes it impossible to have modular precedence information. We should
move to partial orders (sounds like series/parallel orders to me).
-This will be possible with a Bison parser for the grammar, as it will
-make it much easier to extend the grammar.
-
** Correlation b/w precedence and associativity
Also, I fail to understand why we have to assign the same
associativity to operators with the same precedence. For instance,
I was wondering what you think about adding YYACT_PROLOGUE/EPILOGUE
to bison. If you're interested, I'll work on a patch.
-* Move to Graphviz
-Well, VCG seems really dead. Move to Graphviz instead. Also, equip
-the parser with a means to create the (visual) parse tree.
+* Better graphics
+Equip the parser with a means to create the (visual) parse tree.
