   Bison  is  a  parser  generator  in the style of yacc(1).  It should be
   upwardly compatible with input files designed for yacc.

   Input files should follow the yacc convention of ending in .y.   Unlike
   yacc,  the generated files do not have fixed names, but instead use the
   prefix of the input file.  For instance,  a  grammar  description  file
   named  parse.y  would  produce  the  generated  parser  in a file named, instead of yacc's

   This description of the options that can be given to bison  is  adapted
   from  the  node Invocation in the bison.texinfo manual, which should be
   taken as authoritative.

   Bison supports both traditional single-letter options and mnemonic long
   option  names.   Long  option names are indicated with -- instead of -.
   Abbreviations for option names are allowed as long as they are  unique.
   When  a  long option takes an argument, like --file-prefix, connect the
   option name and the argument with =.

   -b file-prefix
          Specify a prefix to use for all bison output  file  names.   The
          names are chosen as if the input file were named file-prefix.c.

          Write  an extra output file containing macro definitions for the
          token type names defined in the grammar and the  semantic  value
          type YYSTYPE, as well as a few extern variable declarations.

          If  the  parser  output  file  is named name.c then this file is
          named name.h.

          This output file is essential if you wish to put the  definition
          of  yylex  in  a separate source file, because yylex needs to be
          able to refer to token type codes and the variable yylval.

          Don't put any #line preprocessor commands in  the  parser  file.
          Ordinarily  bison  puts  them  in  the parser file so that the C
          compiler and debuggers will associate errors  with  your  source
          file,  the  grammar  file.  This option causes them to associate
          errors with the parser file, treating it an  independent  source
          file in its own right.

   -o outfile
          Specify the name outfile for the parser file.

          The  other  output  files' names are constructed from outfile as
          described under the -v and -d switches.

   -p prefix
          Rename the external symbols used in  the  parser  so  that  they
          start  with  prefix  instead of yy.  The precise list of symbols
          renamed is yyparse, yylex, yyerror, yylval, yychar, and yydebug.

          For example, if you use -p c, the names become cparse, clex, and
          so on.

          Output  a  definition of the macro YYDEBUG into the parser file,
          so that the debugging facilities are compiled.

          Write an extra output file containing  verbose  descriptions  of
          the  parser  states and what is done for each type of look-ahead
          token in that state.

          This file also describes all the conflicts, both those  resolved
          by operator precedence and the unresolved ones.

          The file's name is made by removing .tab.c or .c from the parser
          output file name, and adding .output instead.

          Therefore, if the input file is foo.y, then the parser  file  is
          called  by  default.   As  a consequence, the verbose
          output file is called foo.output.

          Print the version number of bison.

          Equivalent to -o;  the  parser  output  file  is  called
,  and the other outputs are called y.output and
          The purpose of this switch is to imitate yacc's output file name
          conventions.   Thus,  the  following shell script can substitute
          for yacc:

          bison -y $*

   The long-named options can be introduced with `+' as well as `--',  for
   compatibility  with previous releases.  Eventually support for `+' will
   be removed, because it is incompatible with the POSIX.2 standard.
