| * This program is a specialisation of the Unix "dd" command in which |
| * either the input or the output file is a scsi generic device, raw |
| * device, a block device or a normal file. The block size ('bs') is |
| * assumed to be 512 if not given. This program complains if 'ibs' or |
| * 'obs' are given with a value that differs from 'bs' (or the default 512). |
| * If 'if' is not given or 'if=-' then stdin is assumed. If 'of' is |
| * not given or 'of=-' then stdout assumed. |
| * |
| * A non-standard argument "bpt" (blocks per transfer) is added to control |
| * the maximum number of blocks in each transfer. The default value is 128. |
| * For example if "bs=512" and "bpt=32" then a maximum of 32 blocks (16 KiB |
| * in this case) is transferred to or from the sg device in a single SCSI |
| * command. |
| * |
| * This version is designed for the Linux kernel 2.4, 2.6, 3, 4 and 5 series. |
