NAME
yyfix - extract tables from y.tab.c

SYNOPSIS
yyfix file [ tables ]

DESCRIPTION
Programs have historically used a script (often named ":yyfix")
to extract tables from the yacc(1) generated file y.tab.c. As the
names of the tables generated by the current version of yacc are
different from those of historical versions of yacc , the shell
script yyfix is provided to simplify the transition.

The first (and required) argument to yyfix is the name of the file
where the extracted tables should be stored.

If further command line arguments are specified, they are taken as
the list of tables to be extracted. Otherwise, yyfix attempts to
determine if the y.tab.c file is from an old or new yacc, and
extracts the appropriate tables.

The tables "yyexca", "yyact", "yypact", "yypgo", "yyr1",
"yyr2", "yychk", and "yydef" are extracted from historical
versions of yacc.

The tables "yylhs", "yylen", "yydefred", "yydgoto",
"yysindex", "yyrindex", "yygindex", "yytable", "yyname",
"yyrule", and "yycheck", are extracted from the current version
of yacc.

FILES
