//-------------------------------------------------------
// Implementation of the TPC clusterer
//
+// 1. The Input data for reconstruction - Options
+// 1.a Simulated data - TTree - invoked Digits2Clusters()
+// 1.b Raw data - Digits2Clusters(AliRawReader* rawReader);
+//
+// 2. The Output data
+// 2.a TTree with clusters - if SetOutput(TTree * tree) invoked
+// 2.b TObjArray - Faster option for HLT
+// 2.c TClonesArray - Faster option for HLT (smaller memory consumption), activate with fBClonesArray flag
+//
+// 3. Reconstruction setup
+// see AliTPCRecoParam for list of parameters
+// The reconstruction parameterization taken from the
+// AliTPCReconstructor::GetRecoParam()
+// Possible to setup it in reconstruction macro AliTPCReconstructor::SetRecoParam(...)
+//
