# This file uses a new release list system developed by Lance Davis for centos.
# The mirror system uses the connecting IP address of the client and
# Update Status of each mirror to pick mirrors that are updated to and
# Geographically close to the client. You shoshould use this for centos updates
# Unless you are manually picking other mirrors.
#
# If the specified list = does not work for you, as a fall back you can try
# Remarked out baseurl = line instead.
