'# The mirror system uses the connecting IP address of the client and the
'# update status of each mirror to pick mirrors that are updated to and
'# geographically close to the client. You should use this for CentOS updates
'# unless you are manually picking other mirrors.
'#
'# If the mirrorlist= does not work for you, as a fall back you can try the
'# remarked out baseurl= line instead.
