Metalinks contain mirror and p2p locations along with checksums and other
metadata for faster and easier downloads. Downloads can be distributed
between mirrors and checksums are automatically verified when it finishes.
Mirrors have location and priority information to make the download more
efficient.

Metalinks for CentOS are automatically generated at
http://download.packages.ro/metalink/centos/ by your mirror RoEduNet Iasi
(http://www.iasi.roedu.net/). These are for CentOS 3.8 and 4.4.

Here's what part of a .metalink looks like:

  <files>  
   <file name="CentOS-4.4-i386-LiveCD.iso">
    <os>Linux-x86</os>
