　　# CentOS-Base.repo

　　# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
　　# 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.
