+*/
+//____________________________________________________________________
//
// Forward Multiplicity Detector based on Silicon wafers. This class
-// contains the base procedures for the Forward Multiplicity detector
-// Detector consists of 5 Si volumes covered pseudorapidity interval
-// from 1.7 to 5.1.
+// is the driver for especially simulation.
+//
+// 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.
//
// The actual code is done by various separate classes. Below is
// diagram showing the relationship between the various FMD classes
-// that handles the geometry
+// that handles the simulation
//

//
// * AliFMD
// This defines the interface for the various parts of AliROOT that
-// uses the FMD, like AliFMDDigitizer, AliFMDReconstructor, and so
-// on.
+// uses the FMD, like AliFMDSimulator, AliFMDDigitizer,
+// AliFMDReconstructor, and so on.
+//
+// * AliFMDv0
+// This is a concrete implementation of the AliFMD interface.
+// It is the responsibility of this class to create the FMD
+// geometry.
//
// * AliFMDv1
// This is a concrete implementation of the AliFMD interface.
// geometry, process hits in the FMD, and serve hits and digits to
// the various clients.
//
-// It uses the objects of class AliFMDSubDetector to do the various
-// stuff for FMD1, 2, and 3
-//
-// * AliFMDRing
-// This class contains all stuff needed to do with a ring. It's
-// used by the AliFMDSubDetector objects to instantise inner and
-// outer rings. The AliFMDRing objects are shared by the
-// AliFMDSubDetector objects, and owned by the AliFMDv1 object.
-//
-// * AliFMDPolygon
-// The code I lifted from TGeoPolygon to help with the geometry of
-// the modules, as well as to decide wether a hit is actually with
-// in the real module shape. The point is, that the shape of the
-// various ring modules are really polygons (much like the lid of a
-// coffin), but it's segmented at constant radius. That is very
-// hard to implement using GEANT 3.21 shapes, so instead the
-// modules are implemented as TUBS (tube sections), and in the step
-// procedure we do the test whether the track was inside the real
-// shape of the module.
-//
-// * AliFMD1, AliFMD2, and AliFMD3
-// These are specialisation of AliFMDSubDetector, that contains the
-// particularities of each of the sub-detector system. It is
-// envisioned that the classes should also define the support
-// volumes and material for each of the detectors.
+// * AliFMDSimulator
+// This is the base class for the FMD simulation tasks. The
+// simulator tasks are responsible to implment the geoemtry, and
+// process hits.
//
-// The responsible person for this module is Alla Maevskaia
-// <Alla.Maevskaia@cern.ch>.
+// * AliFMDReconstructor
+// This is a concrete implementation of the AliReconstructor that
+// reconstructs pseudo-inclusive-multiplicities from digits (raw or
+// from simulation)
//
-// Many modifications by Christian Holm Christensen <cholm@nbi.dk>
+// 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.
