+// 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.
+//
+// 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
+//

+// * AliFMD
+// This defines the interface for the various parts of AliROOT that
+// uses the FMD, like AliFMDDigitizer, AliFMDReconstructor, and so
+// on.
+//
+// * AliFMDv1
+// This is a concrete implementation of the AliFMD interface.
+// It is the responsibility of this class to create the FMD
+// 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.
