        !            18: .I Eyacc
        !            19: is an old version of
        !            20: .IR yacc (1),
        !            21: which produces tables used by the Pascal system and its error recovery
        !            22: routines.
        !            23: .I Eyacc
        !            24: fully enumerates test actions in its parser when an error token
        !            25: is in the look-ahead set.
        !            26: This prevents the parser from making undesirable reductions
        !            27: when an error occurs before the error is detected.
        !            28: The table format is different in
        !            29: .I eyacc
        !            30: than it was in the old
        !            31: .I yacc,
        !            32: as minor changes had been made for efficiency reasons.
