This is the official code released to the Offline Coordinator, Federico Carminati, as of September 19 at 18:10. BUT includes an update to be compatible with HP Unix and fixes two type-os, one in the ITSgeometry_5.euc file, the other replaceing a missing material in the .tme file. The type-o in the .euc file came about from having to renumber the transformations defined by Euclid so that all of the files can be merged into one file. This also contains some cosmetic changes introduce by Federico Carminati and a fix to a memory leak coming from AliITSv* and a typo in AliITSv5.cxx. This code has been updated as of September 25 to fix a bug in AliITSv1.cxx and AliITSv3.cxx. Bjorn S. Nilsen
