10 for them sysctl files? If anybody really needs
11 the source...'
12
13 Well, this documentation is written because so
14 don't know they need to tweak something, or be
15 have the time or knowledge to read the source

25
26 1. you get what you pay for
27 2. it's free

29 The consequences are that I won't guarantee th
30 this document, and if you come to me complaini
31 screwed up your system because of wrong docume
32 feel sorry for you. I might even laugh at you.
33
34 But of course, if you _do_ manage to screw up
35 only the sysctl options used in this file, I'd
36 it. Not only to have a great laugh, but also t
37 you're the last RTFMing person to screw up.
