Hi, Kevin McCarty and I have packaged the software called ROOT, widely used in particle and nuclear physics for the numerical analysis of large data sets. Currently, ROOT cannot go into Debian or non-free due to various license issues. Current ROOT version is 4.04.02 and can be found in deb http://debian.ciencias.uchile.cl/debian-repository \ unstable/root non-free More information regarding ROOT can be found in http://root.cern.ch/ Ricardo Yanez
