/// \class AliMUONReconstructor
///
/// Implementation of AliReconstructor for MUON subsystem.
///
-/// The behavior of the MUON reconstruction can be changed, besides
-/// the usual methods found in AliReconstruction (e.g. to disable tracking)
-/// by using AliReconstruction::SetOption("MUON",options)
-/// where options should be a space separated string.
-///
-/// Valid options are :
+/// The clustering mode and the associated parameters can be changed by using
+/// AliMUONRecoParam *muonRecoParam = AliMUONRecoParam::GetLow(High)FluxParam();
+/// muonRecoParam->Set...(); // see methods in AliMUONRecoParam.h for details
+/// AliRecoParam::Instance()->RegisterRecoParam(muonRecoParam);
///
-/// SAVEDIGITS : if you want to save in the TreeD the *calibrated* digits
-/// that are used for the clustering
+/// Valid modes are :
///
/// SIMPLEFIT : use the AliMUONClusterFinderSimpleFit clusterizer
///
-/// AZ : use the AliMUONClusterFinderAZ clusterizer (default)
+/// SIMPLEFITV3 : SIMPLEFIT with preclustering=PRECLUSTERV3
///
-/// MLEM : another implementation of AZ, where preclustering is external
-/// MLEMV3 : MLEM with preclustering=PRECLUSTERV2
+/// MLEM : use AliMUONClusterFinderMLEM and AliMUONPreClusterFinder for preclustering (default)
+/// MLEMV2 : MLEM with preclustering=PRECLUSTERV2
/// MLEMV3 : MLEM with preclustering=PRECLUSTERV3
///
/// PRECLUSTER : use only AliMUONPreClusterFinder. Only for debug as
///
/// NOCLUSTERING : bypass completely the clustering stage
///
-/// NOSTATUSMAP : disable the computation and usage of the pad status map. Only
-/// for debug !
+/// ------
+///
+/// The behavior of the MUON reconstruction can also be changed, besides
+/// the usual methods found in AliReconstruction (e.g. to disable tracking)
+/// by using AliReconstruction::SetOption("MUON",options)
+/// where options should be a space separated string.
+///
+/// Valid options are :
+///
+/// SAVEDIGITS : if you want to save in the TreeD the *calibrated* digits
+/// that are used for the clustering
+///
+/// DIGITSTOREV1 : use the V1 implementation of the digitstore
+/// DIGITSTOREV2R : use the V2R implementation of the digitstore
///
/// NOLOCALRECONSTRUCTION : for debug, to disable local reconstruction (and hence
/// "recover" old behavior)
///
/// TRIGGERDISABLE : disable the treatment of MUON trigger
///
-/// DIGITSTOREV1 : use the V1 implementation of the digitstore
-/// DIGITSTOREV2R : use the V2R implementation of the digitstore
+/// USEFASTDECODER : makes the digit maker class use the high performance decoder
+/// AliMUONTrackerDDLDecoder instead of AliMUONPayloadTracker.
