It is the responsibility of the different detector groups to maintain and develop the different modules describing the ALICE detectors. The modular structure of the code has been developed to reflect this fact, and changes in one module should not affect the others.
New modules can be provided, incorporated and tested within the AliRoot framework. These should then be submitted and incorporated into the centrally maintained filebase.
Any query or proposal for a change in the code can be addressed to the Alice Off-line Mailing List.
We expect the code to evolve rapidly, as the TDR studies will require frequent modifications and updates, so we have decided to reserve the right to release a new version up to once a week.
The AliRoot framework will support an interface to Geant4. Reconstruction and analysis of simulated events are also supported by AliRoot.
