+// Class AliITSmoduleSSD
+// describes one SSD module
+// The main function of modules is to simulate DIGITS from
+// GEANT HITS and produce POINTS from DIGITS
+//
+// This class keep track of Detector Control System parameters
+// of one SSD module: invalid (dead) strips, gain, capacitive
+// coupling.
+//
+// In this release it make only simulation, and is not completly
+// tuned - up. Simulation will be improved after tests of SSD
+// modules on SPS. Improved simulation and reconstruction will
+// appear in next releas.
+//
+// created by: A.Boucham, W.Peryt, S.Radomski, P.Skowronski
