+	* NEWS: The -g and --graph options now output graphs in Graphviz
+	DOT format, not VCG format.
+	* doc/bison.1: Likewise.
+	* doc/bison.texinfo (Understanding, Bison Options): Likewise.
+	* THANKS: Add Satya Kiran Popuri, who proposed the initial version
+	of this change in
+	<http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
+	* TODO: Remove Graphviz entry.
+	* src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
+	remove vcg.c, vcg.h, vcg_defaults.h.
+	* src/vcg.c, src/vcg.h, src/vcg_defaults.h: Remove.
+	* src/graphviz.c, src/graphviz.h: New files.
+	* src/files.c (compute_output_file_names): Output .dot, not .vcg.
+	* src/files.h: Make comment more generic.
+	* src/main.c (main): Likewise.
+	* src/print_graph.h: Likewise.
+	* src/getargs.c (usage): Make usage description more generic.
+	* src/print_graph.c: Include graphviz.h rather than vcg.h.
+	(static_graph, fgraph): Remove.  All uses changed to pass
+	arguments instead of sharing a static var.
+	(print_core, print_actions, print_state, print_graph):
+	Output graphviz format rather than VCG format.
+	* tests/.cvsignore: Remove *.vcg; add *.dot.
+	* tests/output.at: Expect *.dot files, not *.vcg files.

+
+2006-10-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* data/push.c (yypushparse): Fix memory leak if yymsg is malloced

+	b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,

+	<http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
+	and try to make such failures easier to catch in the future.
+	* data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
+	that's now the caller's responsibility.
+	(yyprocessOneStack, yyrecoverSyntaxError, yyparse):
