+/// This macro reads the generation/reconstruction files in the
+/// input directories (recodir and simdir),
+/// builds a tree that contains, for each event, an array of muons and dimuons
+/// (TClonesArrays of AliMUONTrackLight and AliMUONPairLight objects)
+/// and writes the tree in an output file (outFileName)
+/// Note that if the path for the output file is not explicitly specified,
+/// it will be written in the directory containing the generation/reconstruction
+/// 27-Nov-2006: modified by in order to loop on files
+///
+/// 13 Nov 2007:
+/// Updated this macro to work with new version of AliMUONRecoCheck. Also, we are
+/// now fetching reconstructed track data from ESD and not the track tree, because
+/// the AliMUONTrack objects for reconstructed tracks are no longer stored on disk.
