From 11947d5ba71b18faf8967bc5de38bc0138e5fe8a Mon Sep 17 00:00:00 2001
From: Garrett Wollman <wollman@FreeBSD.org>
Date: Sat, 14 Jan 1995 23:14:25 +0000
Subject: Add a `-p' option, allowing the super-user to directly set a user's
 encrypted password.  Kerberized `login' might use this, if I get around to
 implementing the complete Allspice System behavior.
