NAME
       yyextract -- extract grammar rules from a yacc grammar

SYNOPSIS
       yyextract [-behyV] [-o file] [-t	title] [-w cols] [file ...]

DESCRIPTION
       The yyextract utility extracts the grammar rules	from a yacc grammar.

       The options are as follows:

       -b      Select the Backus-Naur Form (BNF) for the output.

       -e      Select the Extended Backus-Naur Form (EBNF) for the output.

       -h      Output in HTML format.

       -o file
	       Set the output destination to file.

       -t title
	       Specify the page	title for the generated	HTML page.

       -w cols
	       Set  the	width limit of the output (this	sets only the width of
	       the %token header).

       -y      Select the yacc format for the output. This is the default for-
	       mat.

       -V      Print version information on standard output then exit.

NOTES
       The Extended Backus-Naur	Form (EBNF) is like the	Backus-Naur Form (BNF)
       but with	the empty  rules  translated  with  the	 zero-or-one  operator
       (within the brackets '['	and ']').
