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