  XROOTD software framework is a fully generic suite for fast, low latency
  and scalable data access, which can serve natively any kind of data,
  organized as a hierarchical filesystem-like namespace, based on the
  concept of directory. 
  It is usually used with <pkg>sci-physics/root</pkg> and its PROOF
  facilities for cluster computing in high energy physics.
