From b0e9a82310359965c5d0ede45c75387d33cc3ba5 Mon Sep 17 00:00:00 2001
From: Mike Makonnen <mtm@FreeBSD.org>
Date: Tue, 16 Mar 2004 13:46:29 +0000
Subject: o Add an -S option to not attempt to ascertain the validity of a
 shell. o Add a -D option to not attempt to create the home directory. o Treat
 the /nonexistent home directory specially. It means the user has   no home
 directory and it should not be created. o Update Copyright year and my email.
