Why ?Why ?

When moving from CMZ to CVS we tried to create 3 When moving from CMZ to CVS we tried to create 3 independent programs: independent programs:

simulation, reconstruction and analysis

We did not succeed : We did not succeed : there is one program SICB which does everything and several

specific executables.

SICB can be seen as a collection of packages:SICB can be seen as a collection of packages: utility to handle data structures and I/O shared by Gaudi events to handle initialization, data cards, event loop. detdes a detector description package detector specific packages for simulation, reconstruction, trigger analysis packages


Why? (2)Why? (2)

The evolution in time of theses packages is quite The evolution in time of theses packages is quite different:different:

utility and events are stable detector description is rather stable: changes are put in the

geometry database. detector specific evolve at different speed. analysis is independent of the other.

==> Let packages evolve independently.==> Let packages evolve independently. ==> each package carries its own version number ==> each package carries its own version number
