.SH RATIONALE
This program was based on the dd(1p) utility as specified in POSIX. While
character conversion may have been the original intent of dd(1p), it is
irrelevant to its modern use. Because of this, it eschews character conversion
and adds typical option formatting, allowing seeks to be specified in bytes
rather than in blocks, allowing arbitrary bytes as padding, and printing in a
format that’s easy to parse for machines.
