ROOT stand for "OOTs bject-riented echnologies" - it is an object oriented data anlaysis framework written in C++. ROOT has its origin at the Centre Europeenne pour la Recherche Nucleaire (CERN) and is a cross platform tool well-known to high energy physicists, but it's also used in a wide range of other data analysis applications. The system consists of the C/C++ interpreter CINT (for interactive development and rapid prototyping) and hundreds of classes, which provides functionalities u.a. for: - Data Histogram and Minimization Operations - Linear Algebra, Matrix and Vector Operations - Tree, Ntuple and other Data Containers/Stuctures - 2D Graphics, 3D Graphics and Detector Geometry Modeling - Graphical User Interface - Operating System and Networking Interface - Inline Documentation and PostScript Interface - PROOF Server (parallel computing) For more information, user manuals, tutorials, how-to's, examples, discussion groups and so on look at the ROOT web site: WWW: http://root.cern.ch/ Ported to FreeBSD by Simon Lang,
