Minor note, I'm not the person who originally asked.

Another note, koti688 did specifically ask "I want to know what pack and Unpack do excatly" [sic]. Although I will admit that I missed the second question the first time I read it. But in any case, it's pretty clear from the printed output that someone unfamiliar with pack/unpack isn't going to gain much from looking at the output.
