10// SDD geometry, based on ROOT geometrical modeler
11//
12// Its integration to the aliroot framework is done in the AliITSv11Hybrid
13// class (AliITSv11 not being functionnal so far)
14//
15// This geometry has no dependence with aliroot, you can run it with root
16// only, provided that the AliITSv11GeomCable classes are also compiled
