# Update GeoIP packages to new version provided by MaxMind.
#
# Author: Elan Ruusamäe <glen@pld-linux.org>
# 2012-07-04 Created initial version
# 2014-03-04 Rewritten to be smarter when checking for updates avoiding full download if no changes.
# 2014-06-06 Fix finding new versions if multiple previous archives were present
