+//          Options for the TPC Reconstruction in rec.C
+//
+//  4 options can be set to change the input for TPC reconstruction
+//  which overwrites the usage of fUseHLTClusters of the AliTPCRecoParam
+//
+//  1) useRAW        - use RAW, if not present -> do nothing
+//  2) useRAWorHLT   - use RAW, if not present -> use HLT clusters
+//  3) useHLT        - use HLT clusters, if not present -> do nothing
+//  4) useHLTorRAW   - use HLT clusters, if not present -> use RAW
+//
+//  -> The current default is useHLTorRAW
