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 format.

     -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 ']').
