  20 * The PlanetLab boot CD allows you to automatically install this machine as a  *
  21 * node within the PlanetLab overlay network.                                   *
  22 *                                                                              *
  23 * PlanetLab is a global overlay network for developing and accessing new       *
  24 * network services. Our goal is to grow to 1000 geographically distributed     *
  25 * nodes, connected by a diverse collection of links. Toward this end, we are   *
  26 * putting PlanetLab nodes into edge sites, co-location and routing centers,    *
  27 * and homes (i.e., at the end of DSL lines and cable modems). PlanetLab is     *
  28 * designed to support both short-term experiments and long-running services.   *
  29 * Currently running services include network weather maps, network-embedded    *
  30 * storage, peer-to-peer networks, and content distribution networks.           *
  31 *                                                                              *
  32 * Information on joining PlanetLab available at planet-lab.org/consortium/     *
