+* The PlanetLab boot CD allows you to automatically install this machine as a  *
+* node within the PlanetLab overlay network.                                   *

+* PlanetLab is a global overlay network for developing and accessing new       *
+* network services. Our goal is to grow to 1000 geographically distributed     *
+* nodes, connected by a diverse collection of links. Toward this end, we are   *
+* putting PlanetLab nodes into edge sites, co-location and routing centers,    *
+* and homes (i.e., at the end of DSL lines and cable modems). PlanetLab is     *
+* designed to support both short-term experiments and long-running services.   *
+* Currently running services include network weather maps, network-embedded    *
+* storage, peer-to-peer networks, and content distribution networks.           *
+*                                                                              *
+* Information on joining PlanetLab available at planet-lab.org/consortium/     *
