                     48: .Sh DESCRIPTION
                     49: .Nm Kdump
                     50: displays the kernel trace files produced with
                     51: .Xr ktrace 1
                     52: in human readable format.
                     53: By default, the file
                     54: .Pa ktrace.out
                     55: in the current directory is displayed.
                     56: .Pp
                     57: The options are as follows:
                     58: .Bl -tag -width Fl
                     59: .It Fl d
                     60: Display all numbers in decimal.
                     61: .It Fl e Ar emulation
                     62: Interpret system call maps assuming the named emulation instead of "netbsd".
                     63: .It Fl f Ar file
                     64: Display the specified file instead of
                     65: .Pa ktrace.out .
                     66: .It Fl l
                     67: Loop reading the trace file, once the end-of-file is reached, waiting for
                     68: more data.
                     69: .It Fl m Ar maxdata
                     70: Display at most
                     71: .Ar maxdata
                     72: bytes when decoding
                     73: .Tn I/O .
                     74: .It Fl n
                     75: Suppress ad hoc translations.
                     76: Normally
                     77: .Nm kdump
                     78: tries to decode many system calls into a more human readable format.
                     79: For example,
                     80: .Xr ioctl 2
                     81: values are replaced with the macro name and
                     82: .Va errno
                     83: values are replaced with the
                     84: .Xr strerror 3
                     85: string.
                     86: Suppressing this feature yields a more consistent output format and is
                     87: easily amenable to further processing.
                     88: .It Fl R
                     89: Display relative timestamps (time since previous entry).
                     90: .It Fl T
                     91: Display absolute timestamps for each entry (seconds since epoch).
                     92: .It Fl t Ar cnis
                     93: See the
                     94: .Fl t
