From be606510fb37cac8ca7eddadf719efb0598a2ed2 Mon Sep 17 00:00:00 2001
From: Jameson Graef Rollins <jrollins@finestructure.net>
Date: Tue, 3 Feb 2009 01:23:51 -0500
Subject: fix up gen/import-key: - remove stuff about expiration, so we assume
 keys imported/generated with no expiration - set expiration with 'set-expire'
 function - update tests to test key importing and generation - fix some bugs
