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. --------------9qIXlj8HZReJhw9VLppkcspM Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 8bit
