+// Forward Multiplicity Detector based on Silicon wafers. This class
+// 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 simulation
+//
+//
+// +----------+ +----------+

+//
+// * AliFMD
+// This defines the interface for the various parts of AliROOT that
+// 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.
+// 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.
+//
+// * AliFMDReconstructor
+// This is a concrete implementation of the AliReconstructor that
+// reconstructs pseudo-inclusive-multiplicities from digits (raw or
+// from simulation)
+//
+// 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.
