+// Forward Multiplicity Detector based on Silicon wafers. This class
+// contains the base procedures for the Forward Multiplicity detector
+// 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

+// * AliFMD

+// AliFMDReconstructor, and so on.

+// * AliFMDv0

+// geometry.
+//
+// * 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.
+//
+// * AliFMDSimulator
+// This is the base class for the FMD simulation tasks. The
+// 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.
+//
+// * AliFMDG3Simulator
+// This is a concrete implementation of the AliFMDSimulator that
+// uses the TVirtualMC interface with GEANT 3.21-like messages.
