    @section intro Introduction:

    This file contains a short overview of the FMD code.   It is by no 
    means authoritative  - only the code is good for that.  However,
    I'll try to explain things a bit here. 

    @section structure Structure:

    There are 4 libraries build for the FMD.  These are 

    - libFMDbase: This contains the basic stuff, like data classes and
      managers.
    - libFMDsim: This contains code used by the simulation only.  That
      includes the detector class AliFMD and it's derivatives.  It
      also contains the code for building the geometry, as well as the
      digitisers and raw data writer.
    - libFMDrec: Code needed for the reconstruction.  This include the
      reconstruction code itself, as well as a raw data reader.
    - libFMDutil: This is a special library that contains various
      utility classes for the FMD expert/developer/tester.  It
      includes code to read all data produced by the FMD, a simple
      event display, and code to make fake calibration and alignment
      data.  This library is @e not loaded by aliroot
      automatically. The user has to load it herself:
      @code 
      gSystem->Load("libFMDutil.so");
      @endcode
    The content of these libraries is detailed more below. 
    
    @subsection base libFMDbase:

    This currently (18th or March 2006) contains the classes 

    - AliFMDBaseDigit, AliFMDDigit, AliFMDSDigit: Base class for
      digits, real digits, and summable digits.  The are all data
      classes that holds the ADC value(s) for a single strip.
    - AliFMDBoolMap: A map of booleans, one for each strip.
    - AliFMDUShortMap: A map of unsigned short integers, one for each
      strip.
    - AliFMDDetector, AliFMD1, AliFMD2, AliFMD3: 3 classes that holds
      the parameters for each of the 3 FMD sub-detectors.  These
      derive from AliFMDDetector, and are managed by AliFMDGeometry.
      Each of these also contains the translation from sensor
      reference frame to global reference frame.
    - AliFMDRing: Parameters for the FMD rings (inner and outer type).
      These are managed by AliFMDGeometry.
    - AliFMDGeometry: Manager of FMD geometry data. All code queries
      this manager for geometry parameters, so that the data is always
      consistent.  
    - AliFMDParameters: Manager of FMD parameters, like calibration
      parameters.  This class fetches data from CDB if necessary.
      All code queries this manager for parameters, so that the data
      is always consistent. 
    - AliFMDCalibPedestal, AliFMDCalibGain, AliFMDCalibSampleRate,
      AliFMDAltroMapping: Containers of calibration parameters.  These
      correspond to the pedestal and its width, the gain of each
      strip, the oversampling rate used in read-out, and the map from
      hardware address to detector.
    - AliFMDAltroIO, AliFMDAltroReader, AliFMDAltroWriter: Low-level
      classes to do input/output on ALTRO formated buffers. 

  
    @subsection sim libFMDsim:

    This currently (18th or March 2006) contains the classes 

    - AliFMDEdepMap: Cache of energy deposited and total number of
      hits for each strip.  The digitiser AliFMDDigitizer uses this to
      store simulation data before making digits.
    - AliFMDHit: A hit in the FMD active elements, as described by the
      simulation back-end during transport.
    - AliFMD, AliFMDv0, AliFMDv1: Simulation drivers for the FMD.
      AliFMD is the base class. AliFMDv0 corresponds to a simulation
      where no hits are created, but the material distribution is
      right.  AliFMDv1 is like AliFMDv0, except that hits are
      produced.
    - AliFMDGeometryBuilder: Build the FMD geometry in terms of TGeo
      objects.  The information for building the geometry is retrieved
      from AliFMDGeometry.
    - AliFMDBaseDigitizer, AliFMDDigitizer, AliFMDSDigitizer: Base
      class for the digitisers.  AliFMDDigitizer makes `real' digits
      (AliFMDDigit) from hits, and AliFMDSDigitizer makes summable
      digits from hits.
    - AliFMDRawWriter: Writes a pseudo raw data file from the digits
      created by the digitisers.  It uses the AliFMDAltroMapping from
      AliFMDParameters to make the mapping from detector coordinates
      to hardware addresses.

    @subsection rec libFMDrec:

    This currently (18th or March 2006) contains the classes 

    - AliFMDReconstructor: Reconstruct (in a naiive way) the charged
      particle multiplicity in the FMD strips.  This also writes an
      AliESDFMD object to the ESD files (that class is in libESD).

    - AliFMDRecPoint: Reconstructed point in the FMD.  These objects
      are made AliFMDReconstructor. 

    - AliFMDRawReader: Classes to read raw data files. 

    @subsection flow libFMDflow:
    
    This library contains flow analysis code that works similar to 
    histograms. 

    @subsection ana libFMDanalysis:
    
    This library contains analysis code.


    @subsection util libFMDutil:

    This currently (18th or March 2006) contains the classes 

    - AliFMDInput, AliFMDInputHits, AliFMDInputDigits,
      AliFMDInputSDigits, AliFMDInputRecPoints: Base class, and
      concrete classes to read in FMD generated data.  These provide a
      simple and unified way of getting the data.  Hooks are defined
      to process hits, tracks, digits, and reconstructed points, as
      well as geometry and ESD data.   See for example the scripts
      @c DrawHits.C, @c DrawHitsDigits.C, @c DrawHitsRecs.C, @c
      DrawDigitsRecs.C in the @c FMD/scripts sub-directory.

    - AliFMDDisplay: Simple event display for FMD data, including
      hits, digits, reconstructed points and ESD data. 

    - AliFMDCalibFaker, AliFMDAlignFaker: Classes to write fake (or
      dummy) calibration and alignment 	data. 


    @section script Scripts 
    
    Most scripts live in @c FMD/scripts.  The notiable exceptions are 
    @ref Simulate.C, @ref Reconstruct.C, and @ref Config.C 

    @section quick Quick start 

    First, install ROOT.  Then Install TGeant3: 
    @verbatim 
    > cd ~/
    > mkdir alice
    > cd alice
    > cvs -d :pserver:cvs@root.cern.ch:/user/cvs login 
    Password: cvs
    > cvs -d :pserver:cvs@root.cern.ch:/user/cvs co geant3
    > cd geant3
    > make 
    @endverbatim 

    Now you can install AliRoot 
    @verbatim 
    > cd ../
    > cvs -d :pserver:cvs@alisoft.cern.ch:/soft/cvsroot login
    Password: <empty>
    > cvs -d :pserver:cvs@alisoft.cern.ch:/soft/cvsroot co AliRoot
    > cd AliRoot
    > export ALICE_TARGET=`root-config --arch`
    > export ALICE=${HOME}/alice
    > export ALICE_ROOT=${ALICE}/AliRoot
    > export ALICE_LEVEL=new
    > export LD_LIBRARY_PATH=${ALICE_ROOT}/lib/tgt_${ALICE_TERGET}:${LD_LIBRARY_PATH}
    > export PATH=${ALICE_ROOT}/bin/tgt_${ALICE_TERGET}:${PATH}
    > export G3SYS=${ALICE}/geant3
    > make 
    @endverbatim 
    
    To simulate one event, do something like 

    @verbatim 
    > aliroot ${ALICE_ROOT}/FMD/Simulate.C
    @endverbatim 

    To reconstruct the generated event, do 
    @verbatim 
    > aliroot ${ALICE_ROOT}/FMD/Reconstruct.C
    @endverbatim 

    Now, open the file `AliESDs.root' in AliRoot, and browse through  that.

/** @class AliFMD AliFMD.h <FMD/AliFMD.h>
    @brief 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.
