        !            12: .I Eyacc
        !            13: is an old version of
        !            14: .IR yacc (1),
        !            15: which produces tables used by the Pascal system and its error recovery
        !            16: routines.
        !            17: .I Eyacc
        !            18: fully enumerates test actions in its parser when an error token
        !            19: is in the look-ahead set.
        !            20: This prevents the parser from making undesirable reductions
        !            21: when an error occurs before the error is detected.
        !            22: The table format is different in

        !            26: as minor changes had been made for efficiency reasons.
