-	help
-	  Unless you really know what you are doing, you should say Y here.
-	  The reason is that some programs need kernel networking support even
-	  when running on a stand-alone machine that isn't connected to any
-	  other computer. If you are upgrading from an older kernel, you
-	  should consider updating your networking tools too because changes
-	  in the kernel and the tools often go hand in hand. The tools are
-	  contained in the package net-tools, the location and version number
-	  of which are given in <file:Documentation/Changes>.
-
-	  For a general introduction to Linux networking, it is highly
-	  recommended to read the NET-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
