     yacc -- an LALR(1) parser generator

     yacc [-dlrtv] [-b file_prefix] [-o output_filename] [-p symbol_prefix] filename

     Yacc reads the grammar specification in the file filename and generates an LR(1) parser for
     it.  The parsers consist of a set of LALR(1) parsing tables and a driver routine written in
     the C programming language.  Yacc normally writes the parse tables and the driver routine to
     the file y.tab.c.

     The following options are available:

     -b file_prefix
	     Change the prefix prepended to the output file names to the string denoted by
	     file_prefix.  The default prefix is the character y.

     -d      Cause the header file y.tab.h to be written.

     -l      If the -l option is not specified, yacc will insert #line directives in the gener-
	     ated code.  The #line directives let the C compiler relate errors in the generated
	     code to the user's original code.	If the -l option is specified, yacc will not
	     insert the #line directives.  Any #line directives specified by the user will be

     -o output_filename
	     Cause yacc to write the generated code to output_filename instead of the default
	     file, y.tab.c.

     -p symbol_prefix
	     Change the prefix prepended to yacc-generated symbols to the string denoted by
	     symbol_prefix.  The default prefix is the string yy.

     -r      Cause yacc to produce separate files for code and tables.	The code file is named
	     y.code.c, and the tables file is named y.tab.c.

     -t      Change the preprocessor directives generated by yacc so that debugging statements
	     will be incorporated in the compiled code.

     -v      Cause a human-readable description of the generated parser to be written to the file

     If the environment variable TMPDIR is set, the string denoted by TMPDIR will be used as the
     name of the directory where the temporary files are created.


     If there are rules that are never reduced, the number of such rules is reported on standard
     error.  If there are any LALR(1) conflicts, the number of conflicts is reported on standard
