From 649d8f8c9430bc0485cbc6dda54a16bf3b8c4edd Mon Sep 17 00:00:00 2001
From: Stefan Bethke <stb@FreeBSD.org>
Date: Tue, 18 May 1999 22:40:35 +0000
Subject: - Added support for SMP systems to etc/rc.d/setiathome.sh - Added
 etc/setiathome.conf with options to set the nice level, the max.   number of
 processes to run, the working directory, and the the user id   to run as. -
 setiathome.1 was missing from Makefile (and +CONTENTS subsequently) - Updated
 the man page to reflect the changes.
