That simple example makes it trivially easy to understand.  I remember 
trying to figure that out previously via the manual and I just got more 
confused.  There's no merit to obfuscation tho you'd not know that 
reading some Linux/Unix man pages.  It's a critical lesson: what you see 
is not what you get, you hafta understand the hidden structure of your 
data.
