From 30692c67a567c223b3fb752fd8781407c783db79 Mon Sep 17 00:00:00 2001
From: Dirk von Suchodoletz
Date: Mon, 22 Jan 2007 00:47:54 +0000
Subject: Recoded the shell "(u)sleep" functions, depends on /proc by now, but
 should not impose to much (obsoletes rev. 629). Added AUTHORS file. Switched
 off halt/shutdown links for initial/boot.d scripts (in functions seems no
 need, but may produce problems if switched on)
