• Bindings - packages related to the interplay with other programming languages (Python, Ruby)
• Cint - the C++ interpreter
• Core - the basic ROOT functionality
• Geometry - building, representing and drawing geometrical objects
• 2D Graphics - ROOT's two dimensional graphics interface
• 3D Graphics - ROOT's three dimensional graphics interface
• Graphical User Interface - from basic GUI elements to ROOT's own, complete dialogs
• Histograming - counting values, spectra, and drawing them
• HTML - the documentation generator
• Input/Ouput - storing and reading data
• Mathemathics - everything one can use to calculate: minimizers, matrixes, FFT, and much more
• Miscellaneous - things that didn't make it into the other groups: table
• Monte Carlo - monte carlo and physics simulation interfaces
• Networking - network-related parts, e.g. protocols and authentication interfaces
• PROOF - parallel ROOT facility
• RooFit - a fitting library
• RooStats - a collection of statistical tools
• SQL - database interfaces
• TMVA - multivariate analysis tools
• Trees - ROOT's unique container class and related utilities
