+/// \class AliMUONReconstructor
+///
+/// Implementation of AliReconstructor for MUON subsystem.
+///
+/// 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);
+///
+/// Valid modes are :
+///
+/// SIMPLEFIT : use the AliMUONClusterFinderSimpleFit clusterizer
+///
+/// SIMPLEFITV3 : SIMPLEFIT with preclustering=PRECLUSTERV3
+///
+/// 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
+/// the produced clusters do not have a position, hence the tracking will not
+/// work
+/// PRECLUSTERV2 : another version of the preclustering
+/// PRECLUSTERV3 : yet another version of the preclustering
+///
+/// COG : use AliMUONClusterFinderCOG clusterizer. Not really a production
+/// option either, as center-of-gravity is generally not a good estimate
+/// of the cluster position...
+///
+/// PEAKCOG : COG cluster finder around local maxima
+/// PEAKFIT : fit around local maxima with up to 3 peaks, COG otherwise
+///
+/// NOCLUSTERING : bypass completely the clustering stage
+///
+/// ------
+///
+/// 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
+///
+/// NOFASTTRKDECODER : makes the digit maker class use the non-high performance decoder
+/// AliMUONPayloadTracker instead of AliMUONTrackerDDLDecoder.
+///
+/// NOFASTTRGDECODER : makes the digit maker class use the non-high performance decoder
+/// AliMUONPayloadTrigger instead of AliMUONTriggerDDLDecoder.
+///
+/// NOFASTDECODERS : makes the digit maker class use the non-high performance decoders
+/// AliMUONPayloadTracker and AliMUONPayloadTrigger.
