@(#)yacc.1 5.3 (Berkeley) 05/12/90
The following options are available:
-b prefix The -b option changes the prefix prepended to the output file names to the string denoted by prefix. The default prefix is the character y.
-d The -d option causes the header file y.tab.h to be written.
-l If the -l option is not specified, yacc will insert \#line directives in the generated 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 retained.
-t The -t option will change the preprocessor directives generated by yacc so that debugging statements will be incorporated in the compiled code.
-v The -v option causes a human-readable description of the generated parser to be written to the file y.output.
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.
