From df07c87b8986dfc0b840484cc841f8b708ae25cb Mon Sep 17 00:00:00 2001
From: Gunter Knauf <gk@gknw.de>
Date: Mon, 11 Feb 2008 15:00:00 +0000
Subject: [PATCH] added strict to make sure all vars are properly defined;
 added -t switch to make text info of CAs optional; added -q switch to be
 really quiet.
