+# 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.
