From 7e6279057a57ef44c11349e594ad392fbfce0098 Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Sun, 3 Feb 2013 14:26:10 -0600
Subject: Add new pgp_import command; replaces import_signatures

This command now imports keys, subkeys, and signatures of those keys &
subkeys. This will allow us to actually match developers with their
packages signed by subkeys rather than the primary key.
