  where:
    app         if argument is 1 then open OFILE in append mode
    bpt         is blocks_per_transfer (default: 128)
    bs          block size (default is 512)
    cat         xcopy segment descriptor CAT bit (default: 0)
    conv        ignored
    count       number of blocks to copy (def: device size)
    dc          xcopy segment descriptor DC bit (default: 0)
    fco         xcopy segment descriptor FCO bit (default: 0)
    ibs         input block size (if given must be same as 'bs=')
    id_usage    sets list_id_usage field to hold (0), discard (2) or
                disable (3)
    if          file or device to read from (def: stdin)
    iflag       comma separated list of flags applying to IFILE
    list_id     sets list_id field to ID (default: 1 or 0)
    obs         output block size (if given must be same as 'bs=')
    of          file or device to write to (def: stdout), OFILE of '.'
                treated as /dev/null
    oflag       comma separated list of flags applying to OFILE
    prio        set xcopy priority field to PRIO (def: 1)
    seek        block position to start writing to OFILE
    skip        block position to start reading from IFILE
    time        0->no timing(def), 1->time plus calculate throughput
    verbose     0->quiet(def), 1->some noise, 2->more noise, etc
    --help|-h   print out this usage message then exit
    --on_dst    send XCOPY command to OFILE
    --on_src    send XCOPY command to IFILE
    --verbose|-v   same action as verbose=1
    --version|-V   print version information then exit

Copy from IFILE to OFILE, similar to dd command; but using the SCSI
EXTENDED COPY (XCOPY(LID1)) command. For list of flags, use '-hh'.
