From dd9b9a1d118960ca9f2ffc50b054eaab13efebf7 Mon Sep 17 00:00:00 2001
From: imp <imp@FreeBSD.org>
Date: Mon, 24 Jun 2002 06:09:54 +0000
Subject: Document -L and -l. Change -l -> -L to match OpenBSD (since we
 haven't MFC'd it yet). -l will now list stations that are associated with a
 hostap (preliminary)

MFC After: 2 weeks
