Using option ``-g'' or long option ``--graph'', you can generate a gram_filename.vcg file containing a VCG description of the LALR (1) automaton of your grammar. * src/main.c: Call to print_graph() function. * src/getargs.h: Update. * src/getargs.c (options): Update to catch `-g' and `--graph' options. (graph_flag): New flag. (longopts): Update. (getargs): Add case `g'. * src/files.c (graph_obstack): New obstack struct. (open_files): Initialize new obstack. (output_files): Saves graph_obstack if required. * src/files.h (graph_obstack): New extern declaration. * src/Makefile.am: Add new source files.
