From 432baeee55f382bbf5fbe951b93f022306be4ac3 Mon Sep 17 00:00:00 2001
From: "Tom G. Christensen" <tgc@jupiterrise.com>
Date: Sat, 6 Dec 2003 14:55:30 +0000
Subject: [PATCH] A major overhaul. New functionality added: - 'hide' meta file
 to list files that should be 'nohist' in the IDB - 'ops' meta file to list
 files and associated ops - 'depends' meta file to list prereqs for the
 specfile.

Several new functions where introduced and a few old ones where
updated.

Fixed a bug in create_idb which resulted in all toplevel image
descriptions being set to the first one listed in image.conf

Extended subsys.conf to use wildcards to match files
for the subsystems

What's missing currently is the ability to check
if there are unpackaged files left in the staging
area, like rpm does.

New functionality has been ligthly tested
