+// This class builds AliTPCtrack objects from generated tracks to feed
+// ITS tracking (V2). The AliTPCtrack is built from its first hit in
+// the TPC. The track is assigned a Kalman-like covariance matrix
+// depending on its pT and pseudorapidity and track parameters are
+// smeared according to this covariance matrix.
+// Output file contains sorted tracks, ready for matching with ITS.
+//
+// See implementation file for more details.
