.Nd copy and/or verify mag tapes
.Sh SYNOPSIS
.Nm
.Op Fl cvx
.Op Fl s Ar maxblk
.Oo Ar src Op Ar dest
.Oc
.Sh DESCRIPTION
.Nm
is designed to copy magnetic tapes.  The only assumption made
about the tape is that there are two tape marks at the end.
.Nm
with only a source tape
.Pf ( Ar /dev/rst0
by default) specified will print
information about the sizes of records and tape files.  If a destination
is specified a copy will be made of the source tape.  The blocking on the
destination tape will be identical to that used on the source tape.  Copying
a tape will yield the same output as if just printing the sizes.
.Pp
Options:
.Bl -tag -width s_maxblk
.It Fl c
Copy
.Ar src
to
.Ar dest
and then verify that the two tapes are identical.
.It Fl s Ar maxblk
Specify a maximum block size,
.Ar maxblk .
.It Fl v
Given the two tapes,
.ar src
and
.Ar dest
verify that they are identical.
.It Fl x
Output all informational messages to the standard error.
This option is useful when
.Ar dest
is
.Pa /dev/stdout .
