//   OS> root ../scripts/ROOT/ELYSE.C

// Note :
//   The ELYSE_batch.exe program produces a ELYSE.root file.
//   This file sould have been produced with the "export=root"
//   option when creating the AIDA::ITree for this file
//   (see ELYSE::Analysis constructor).
//     By default the Lab package does not stream its histograms
//   as THs of ROOT (because the AIDA histos are more rich). 
//   In ordet that ROOT plot the saved histos, the Lab::Histograms
//   can be saved as THs by using the "export=root" option.
