To design LArSoft code, it's important to understand the core LArSoft suite and all the components used by it. Reference the items below when designing new software.

_gallery_ provides lightweight access to event data in art/ROOT files outside the art event processing framework executable. It is not an alternative framework; rather, it provides a library that can be used to write programs that need to read (but not write) art/ROOT files. Information is available at: http://art.fnal.gov/gallery/

ROOT and Geant4 do not use namespaces. In general, ROOT classes begin with "T" (e.g., "TTree":http://root.cern.ch/root/html522/TTree.html, "TH1":http://root.cern.ch/root/html522/TH1.html) while "Geant4 classes":http://geant4www.triumf.ca/lxr/ begin with "G4" (e.g., "G4Track":http://geant4www.triumf.ca/lxr/source//track/include/G4Track.hh, "G4Step":http://geant4www.triumf.ca/lxr/source//track/include/G4Step.hh). Exception: Some of the newer ROOT sub-packages have namespaces (such as @ROOT::Math::@, @ROOT::Fit::@, @ROOT::Minuit2::@, @Reflex::@, @TMVA::@).
53 20 Katherine Lato
54 36 Katherine Lato
Some of these packages duplicate functionality; e.g., 4-vectors are implemented in both "ROOT":http://root.cern.ch/root/html522/TLorentzVector.html and "CLHEP":http://proj-clhep.web.cern.ch/proj-clhep/doc/CLHEP_2_1_2_2/doxygen/html/LorentzVector_8h.html. Given a choice, use a package that's higher in the above tables over one that's lower; e.g., choose ROOT classes over their CLHEP equivalents.
