        !            41: in the current

        !            48: .Tp Fl n
        !            49: Suppress ad hoc translations.  Normally

        !            51: tries to decode many
        !            52: system calls into a more human readable format.  For example, ioctl
        !            53: values are replaced with the macro name and errno values are replaced
        !            54: with the
        !            55: .Li sys_errlist
        !            56: string.  Suppressing this feature yields a more consistent
        !            57: output format and is easily amenable to further processing.
