//____________________________________________________________________

// Forward Multiplicity Detector based on Silicon wafers. This class

+// The Forward Multiplicity Detector consists of 3 sub-detectors FMD1,
+// FMD2, and FMD3, each of which has 1 or 2 rings of silicon sensors.
//
// This is the base class for all FMD manager classes.

// * AliFMD
// This defines the interface for the various parts of AliROOT that
// simulator tasks are responsible to implment the geoemtry, and
// process hits.
//
-// * AliFMDGeoSimulator
-// This is a concrete implementation of the AliFMDSimulator that
-// uses the TGeo classes directly only.
+// * AliFMDReconstructor
+// This is a concrete implementation of the AliReconstructor that
+// reconstructs pseudo-inclusive-multiplicities from digits (raw or
+// from simulation)
//
-// * AliFMDG3Simulator
-// This is a concrete implementation of the AliFMDSimulator that
-// uses the TVirtualMC interface with GEANT 3.21-like messages.
+// Calibration and geometry parameters are managed by separate
+// singleton managers. These are AliFMDGeometry and
+// AliFMDParameters. Please refer to these classes for more
+// information on these.
