From 1b55b1a3640da3ec2b032dcea3f4f7cbdff82303 Mon Sep 17 00:00:00 2001
From: Martin Mares <mj@ucw.cz>
Date: Mon, 29 May 2000 10:32:37 +0000
Subject: Spelling fixes.

Added skeleton for subchapters on all the protocols. Each subchapter should
contain:

	Introduction (brief intro to the protocol, where should it be used,
		references to the relevant standards)
	Configuration
	Attributes
	Example

Added a more detailed description of RIP attributes.
