    Avoid to expand the environment variables in the strings.
 
 ================ GaudiKernel v25r0 ====================================
 ! 2008-06-12 - Marco Clemencic

    - Prints out more information about the various History objects to the output
      file.
 
 ! 2008-06-02 - Marco Clemencic
  - Task #5809. Extension to Gaudi Application state machine.
    First implementation of the proposed extension.
    A new interface (IStateful) has been added to provide a common way of
    interacting with the state machine.
    The interfaces IService, IAlgorithm and IAlgTool have been extended with the
    methods from IStateful, and ISvcManager and IAlgManager have been extended to
    support the new states.
    The states and the transition have been defined in enums
    (Gaud::StateMachine::State, Gaudi::StateMachine::Transition), and the
    constraints on the possible changes are enforced by the function
    Gaudi::StateMachine::ChangeState, which throws an exception if the transition
    is not allowed.
    Since algorithms and tools do not support all the states, the state
    Gaudi::StateMachine::CONFIGURED is reached after the constructor. Services
    are constructed in the state Gaudi::StateMachine::OFFLINE and become
    Gaudi::StateMachine::CONFIGURED in the base class initialize method (as
    defined in patch #1757).
    The methods Algorithm::setInitialized and Algorithm::setFinalized has been
    removed.
    IAuditor has been extended to support auditing of the new transitions (start
    and stop).
    The Reflex dictionary has been updated to include the new classes/enums. 
 
 ! 2008-05-29 - Charles Leggett
  - Changed the name of the extension for libraries on OSX from ".dylib" to ".so".
 
 ! 2008-05-13 - Vanya Belyaev
  - Patch #1756. Improvements for Chrono/ChronoStat&IChronoSvc
    - Removal of many (ugly) obsolete lines, overall cleanup, improved flexible
      print-out and other improvements.
    - GaudiKernel/IChronoSvc.h
      - The basic type from IChronoSvc now is "double" instead of "longlong".
      - Change the return type from void to "(const)StatEntity*" for the methods
        chronoStart/Stop.
    - GaudiKernel/ChronoEntity.h, src/Lib/ChronoEntity.cpp
      - The class is essentially rewritten (keeping the same public interface) in
        terms of the generic counter StatEntity. And internally it is just a set
        of three generic counters (for user/kernel&elapsed time correspondingly).
        New features includes the better control over the printout through new
        methods: outputUserTime, outputSystemTime, outputElapsedTime, outputTime.
    - GaudiKernel/Chrono.h
      - Make this tiny helper class simpler and more efficient:
        - for the usage with IChronoSvc, avoid one virtual call
        - allow the usage with ChronoEntity class
 
 ! 2008-05-09 - Marco Clemencic
  - Added small interface (IFileAccess) for services/tools that allow read-only
    file access agnostic of the storage backend (filesystem, web, CondDB, ...).
  - Fixed a minor problem in ProcessJobOptions.py strip away spaces in component
    and property names ("MyAlg . MyProp" -> "MyAlg.MyProp"). 
 
 ================ GaudiKernel v24r0 ====================================
 ! 2008-04-04 - Vanya BELYAEV
  - Patch #1751. Fixed a typo in Stat::operator-=.
 
 ! 2008-04-04 - Marco Clemencic
  - Bug #35201. Python options parser '//' interpreted as comment in strings.
    Fixed by adding an extra check in ProcessJobOptions.py to allow '//' in
    strings (like URLs). The fix is not perfect because requires that the string
    is on a single line, but at least allows it.
  - Fixed Bug #34680. Bad implementation of Service::messageSvc.
    The obsolete methods now forward the call to the correct ones.
    (anyway they should be removed at some point)
  - Fixed a problem introduced with patch #1757.
    Modified DataStreamTool to call sysInitialize instead of initialize for
    conversion services.
  
 ! 2008-04-04 - Charles Leggett
  - Patch #1757. detect creation/initialization loops for services.
    Modified the way the state of the service is set:
     - the base class initialize sets the state to CONFIGURED
     - the service becomes INITIALIZED in the sysInitialized, after the
       specialized service completed (successfully) the initialization.
  
 ! 2008-04-03 - Sebastien Binet / Martin Woudstra
  - Bug #34752/Patch #1747. GaudiHandleArray.__getstate__ prevents pickling.
    Fixed.
 
 ! 2008-04-03 - Vanya BELYAEV
  - Patch #1751.
    Change the signature of declareProperty/declareRemoteProperty methods
     - for PropertyMgr form "void" to "Property*"
     - for Algorithm/Service/AlgTool/Auditor base classes from StatusCode to
       "Property*"
 
    The previous return value was completely useless: 
     - either "void" or (always) StatusCode::SUCCESS
 
    With the pointer to the actual property returned, one can easily use it, e.g.
    to declare handlers as in:
    //----------------------------------------------------------------------
    class MyAlg : public Algorithm
    {
    
    public: 
 
      // constructor 
 
      MyAlg ( ... ): Algorithm ( ... ) 
                   , m_property( .... ) 
      {
        declareProperty ("Property" , m_property , "some documentation") 
          -> declareUpdateHandler ( &MyAlg::handler ) ;
      }      
 
    private:
 
      SOMETYPE m_property;
 
    };
    //----------------------------------------------------------------------
 
 ! 2008-04-03 - Marco Clemencic
  - Patch #1725. New IAuditor interface.
    - The Auditor member functions are now only 8, for all the combinations of:
      * before or after
      * standard event or custom event
      * INamedInterface* or string
    - All the after methods accept a StatusCode (if not specified, a SUCCESS with
      the checked flag set is used).
    - The obsolete member functions are kept for backward compatibility.
    - The default implementations of "before" and "after" are using the obsolete
      methods to make legacy Auditors to work.
    - IAuditorSvc is now an extension of IAuditor.
    - AuditorGuard has been adapted to the new interface and the audit with a
      status code check is simpler.
    - The standard event types defined in the enum IAuditor::StandardEventType
      can be printed and converted to strings with operator<<. 
 
 ! 2008-04-02 - Marco Clemencic
  - Python job options:
    - Removed the possibility of assigning a tool to an attribute of a
      configurable if that attribute/property does not exists. It was intended to
      allow simple declaration of private tools, but it is dangerous because it
      avoids the checking of the spelling of properties. 
    - Modified Configurable.addTool() to accept a subclass of ConfigurableAlgTool
      as first argument (as well as an instance) to avoid the instantiation of an
      unneeded instance of the public tool configurable. 
 
 ! 2008-03-11 - Hubert Degaudenzi
  - added 2 patterns to create and use helper library for genconf. Some libraries
    need to have other preloaded libraries in order to perform the genconf 
    procedure correctly. While this can be fixed on linux with the 
    LD_PRELOAD environment variable, this is not possible on windows. Thus
    the genconf executable takes an extra argument "--load-library" to which
    the full path of the helper library is passed.
 
 ! 2008-03-07 - Marco Clemencic
  - Added a work around for ROOT bug #34282 in dict/dictionary.xml (excluded few
    data members of Gaudi::Time).
  - Fixed Bug #34046. False warning when mixing Python options and old options.
    The check on the case of old options have been improved.
 
 ================ GaudiKernel v23r4 ====================================
 ! 2008-02-28 - Marco Clemencic
  - Minor change to fix a regression. The line
 
      #include"file.opts"
 
    is understood by the JobOptsSvc, but it was not by the Python parser.
 
 ! 2008-02-27 - Charles Leggett
  - Patch #1711. Get all instances of a tool type.
    Function used in the Atlas event display.
 
 ! 2008-02-27 - Marco Clemencic
  - Hack to avoid a conflict in the way Configurables are used in Athena and
    Gaudi.  In GaudiPython they are used in the AppMgr constructor, while in
    Athena they are used in a different moment (and not even all of them are
    needed).
    The conflict is resolved by using a function to return the needed
    configurables, implemented to return the keys of allConfigurables for Gaudi
    and and empty list for Athena. 
 
 ! 2008-02-27 - Wim Lavrijsen
  - Patch #1710. Convenience method for removing entries from GaudiHandleArray
    Add a simple convenience method for deleting tools from a ToolHandleArray by
    name, rather than having to locate them first.
 
 ! 2008-02-21 - Marco Clemencic
  - Moved the release of m_messageSvc and m_pAuditorSvc from Service::~Service to
    Service::sysFinalize.
 
 ! 2008-02-21 - Yushu Yao
  - Patch #1687. Adding getPropertyMgr() in AlgTool
    This is needed to develop double use tools (tools that can be used in Gaudi
    as well as in ROOT) in Athena.
 
 ! 2008-02-20 - Hubert Degaudenzi
  - added static function to Message.{h,cpp} in order to be able to access 
    Message::DEFAULT_FORMAT and Message::DEFAULT_TIME_FORMAT.
 
 ! 2008-02-04 - Charles Leggett
  - Patch #1668.
    In Python 2.5, the method __str__ of ServiceHandles gets called causing some
    problems. The reason has to be investigated, but the patch allows to work.
    
 ! 2008-02-04 - Yushu Yao
  - Patch #1666: Add AlgTool::declareRemoteProperty
    Added the member function declareRemoteProperty to AlgTool (present in
    Algorithm and Service).
 
 ! 2008-02-04 - Marco Clemencic
  - Fixed bug #33209: Deprecated raising a string with Python 2.5
    Added a class for errors occurring during the parsing (ParserError).
 
 ! 2008-01-29 - Marco Clemencic
  - Python options:
    Modified added a flag to the Configurable base class to block assignments.
    The flag is set in GaudiPython.AppMgr after the application manager has been
    configured, to prevent that people try to manipulate the configuration when
    it is too late.
    The lock does not (and cannot) work for in-place changes (like += on a list).  
 
 ! 2008-01-29 - Vanya BELYAEV
  - Modified IInterface::hash32 to use and return "unsigned int" instead of
    "unsigned long" for portability.
 
 ================ GaudiKernel v23r3 ====================================
 ! 2008-01-18 - Marco Clemencic
  - Fixed bug #32549.
    Changed the level of the message about the AbortEvent incident from ERROR to
    DEBUG. 
  - Fixed a compilation warning in genconf.cpp with Boost 1.34.1 on Win32.  
 
 ! 2008-01-14 - Vanya BELYAEV
  - Patch #1581.
    - GaudiKernel/Parsers.h, src/Lib/ParseMaps.cpp
       add the parser functions for parsion of following types:
       1) std::map<int,std::string>
       2) std::map<unsigned int, std::string>
     These types play important roles for LHCb-HLT and are requested 
       by Gerhard Raven 
 
 ! 2008-01-11 - Gerhard Raven
  - patch #1621 (bug #32466).
    Add to IToolSvc/ToolSvc the possibility of using observers to monitor the
    creation of and retrieval of tools.
 
 ! 2008-01-11 - Marco Clemencic
  - Python options:
    - Modified Configurable.addTool to set the property with the same name of the
      tool (if it exists), so that it not hides the tool reference.
    - Modified PropertyProxy.__get__ to allow direct access to the default for
      dictionaries as well as for lists.
    - Added the helper class Configurable.PropertyReference to allow the late
      binding of properties as it was possible in old options (mainly needed for
      backward compatibility).
      The option:
      
         MyAlg.MyProp = @AnotherAlg.AProp;
         
      translates to:
      
         MyAlg().MyProp = Configurable.PropertyReference("AnotherAlg.AProp")
      
    - Modified the parser of old job options to correctly translate references.
    - Modified ConfigurableAlgTool.getFullName to return only the instance name
      (instead of the fully qualified name).
    - Allow the wrong case for properties in old option files, but issue warnings.
    - Modified the default logger to print "GaudiKernel" instead of "Athena" and
      prepend a '#' to the message to allow evaluation of the standard output in
      Python (needed in Ganga).
 
 ! 2008-01-10 - Marco Clemencic
  - Fixed a problem in ProcessJobOptions.py occurring when option values have '\'
    inside (filenames on Windows).
 
 ! 2008-01-09 - Marco Clemencic
  - Python options:
    - Take the values for VERBOSE, DEBUG, INFO, WARNING, ERROR, FATAL always from
      GaudiKernel.Constants.
    - Made "Configurable" equivalent to "str", so that it is possible to set a
      string property from a configurable instance.  It allows something like:
      
        mySvc = AService("theService",...)
        myAlg = AnAlgorithm("theAlgorithm")
        myAlg.ServiceToUse = mySvc
 
 ! 2008-01-08 - Marco Clemencic
  - Fixed a problem in ProcessJoboptions.py: allow have white spaces before the
    '#' sign of directives.
 
 ! 2007-12-20 - Marco Clemencic
  - Improved the message of DataSvc when re-throwing a std::exception. Now the
    message contains the type of the exception.
  - Added a constructor for GaudiException accepting a std::exception. The type
    of the passed exception and its message are appended to the message of the
    GaudiException.
  - Fixed a problem in ProcessJoboptions.py when DOS new-lines were found on
    Unix. 
  
 ! 2007-12-19 - Marco Clemencic
  - Fixed a couple of typos in Map.h (preventing the generation of dictionary).
  - Check if a value is in the list before trying to delete it when interpreting
    "-=" in old job options.
  - Restored the original logic for parsing list in old job options (replace all
    "{}" with "[]", unless there is a ':').
     
 ! 2007-12-12 - Marco Clemencic
  - patch #1585.
    - Added the templated function pp_cast<DEST>(SRC**) to replace the common casts
        (void**)&pointer
      and
        (IInterface *&)m_mySvc
      to avoid the warning
        "dereferencing type-punned pointer will break strict-aliasing rules"
    - Fixed warnings about breaking of strict-aliasing rules (gcc 4.1 optimized).
 
 ! 2007-12-03 - Markus Frank & Marco Clemencic
  - Implemented the Win32 version of the code in DsoUtils.h, with some
    simplification.
 
 ! 2007-11-30 - Marco Clemencic
  - Fixed DsoUtils.h to work on OSX too.
  - Fix for bug #31677.
    Move GaudiHandles.py from GaudiPython to GaudiKernel.
 
 ! 2007-11-28 - Sebastien Binet
  - patch #1560.
    Minor change to avoid possible injection of GaudiKernel.Configurable through
    importOptions.
 
 ! 2007-11-26 - Marco Clemencic
  - Fixed a problem with the dictionary and ROOT >= 5.16.
 
 ! 2007-11-21 - Marco Clemencic
  - Fixed few compilation warnings on osx in the dictionary.
 
 ! 2007-11-20 - Marco Clemencic
  - Fixed few compilation warnings on win32 in the dictionary.
 
 ================ GaudiKernel v23r2 ====================================
 ! 2007-11-16 - Marco Clemencic
  - Added a new incident type (AbortEvent) that force the (Minimal)EventLoopMgr
    to skips all the top algorithms still to be executed for the current event.
    It can be used when a reconstruction step fails so it does not make sense to
    process the event, but we do not want to stop the application.   
  - Fixed a bug in the old job option interpretation if mixed with python
    options.
    The sequence:
      MessageSvc.OutputLevel = 1
      #include "SetMsgSvcOutLvlTo2.py"
      MessageSvc.OutputLevel = 1
    was not correctly setting the output level (if SetMsgSvcOutLvlTo2.py sets the
    output level).
 
 ! 2007-11-15 - Vanya Belyaev
  - patch #1523.
    Add possibility to have properties of the types std::map<int,int> and
    std::vector<std::pair<int,int> > (the second case is perfectly suited
    for Helder Lopez' request of the list of event/run numbers)
    modified files:
     - GaudiKernel/Parsers.h
       add two functions "parse" for parsing of new types
     - src/Lib/Parse*.cpp
       add the implementation of parsing functions
 
 ! 2007-11-14 - Marco Clemencic
  - Added the function GaudiKernel.Configurable.purge to clean up all the
    configurables and the list of already imported files from the memory.
    After a call to "purge" one is able to restart the configuration from scratch
    without having to leave the python session.
     
 ! 2007-11-13 - Marco Clemencic
  - Instead of generating *Conf.py files trying to import AthenaCommon and fail
    back on GaudiKernel, use the module GaudiKernel.Proxy, which internally does
    the same kind of trick but only once.
  
 ! 2007-11-13 - Sebastien Binet
  - patch #1520 (bug #31097)
    Removed a duplicated data member in ServiceHandle (same information already
    available in the base class).
  - patch #1158
    Modified genconf.exe to generate modules (*_confDb.py) with a smaller memory
    footprint. The code to fill the DB is encapsulated in a function that is then
    deleted after being called. 
 
 ! 2007-11-12 - Marco Clemencic
  - Moved the *.qmt files to the implicit suite (directory) "gaudikernel.qms".
 
 ! 2007-11-08 - Marco Clemencic
  - task #5807.
    Added the header GaudiKernel/SerializeSTL.h to provide implementations of
    operator<< for some common STL containers and GaudiUtils::*Map.
    The implementations live in the namespace GaudiUtils. To use them, one have
    to add "using namespace GaudiUtils" (in the relevant scope).
    Tests have been added too.
 
 ! 2007-11-02 - Marco Clemencic
  - Added a temporary work-around for OSX in ProcessDescriptor.cpp.
    To get timing information, it tries to open /proc/$PID/stats, which does not
    exist in OSX. The alternative is to use some other mechanism, but the one
    implemented in ProcessDescriptor seems to cause a segmentation fault.
    (to be investigated) 
 
 ! 2007-10-31 - Marco Clemencic
  - Rewritten ProcessJobOptions.py. Major changes:
    - honor the #pragma print on/off in old options
    - print a warning if a file is included twice (the second time it is ignored)
    - allow inclusion of ".py" and ".pkl" files from ".opts" files (this is the
      main reason fror the rewrite)
    - moved importOptions from Gaudi.Configaration to ProcessJobOptions to allow
      better recursion
 
 ! 2007-10-31 - Marco Clemencic
  - Minor change to the IUpdateManagerSvc interface (added the function :purge")
 
 ! 2007-10-29 - Pere Mato
  - KeyedObjectManager.cpp: changed order of specialization and instantiation
    to please gcc 4.0
 
 ! 2007-10-22 - Marco Clemencic
  - Use the pattern QMTest and add a .qmt file (QMTest test description) to run
    the DirSearchPath test.
  - Modified DirSearchPath_test to work on Windows too.
 
 ! 2007-10-16 - Paolo Calafiura
  - patch #1416. new DirSearchPath method and test
    - Added DirSearchPath::find_all
    - Moved the test from GaudiSvc to GaudiKernel
 
 ================ GaudiKernel v23r1 ====================================
 ! 2007-10-10 - Pere Mato
  - Corrected bug of ProcessJobOptions.py detected by Marco C. when using filenames with
    environments.
 
 ! 2007-10-09 - Marco Clemencic
  - Moved DirSearchPath from GaudiSvc/src/JobOptionsSvc to GaudiKernel
    (requested by Paolo Calafiura).
    Note: the 2 tests using DirSearchpath are still in GaudiSvc.
 
 ! 2007-10-02 - Pere Mato
  - Patch #1400.
    Support for pickle files in python configurations.
    Fixed various bugs in parsing old joboptions files
 
 ! 2007-09-28 - Vanya Belyaev
  - Patch #1345.
    minor modifications to improve Tuples::TupleObj (GaudiAlg package)
    - GaudiKernel/NTuple.h
        1) substitute the explicit specialization for NTuple::Range with 
           the regular calls of std::numeric_limits<T>::min()/max()
        2) disable "#ifndef ALLOW_ALL_TYPES"
 
 ! 2007-09-26 - Vanya Belyaev
  - patch #1375. Allow configuration of Histogram1D from job options.
    - New class Gaudi::Histo1DDef for histogram description/definition.
    - Implementation of parsing for new histogram properties.
      (Sascha Mazurov)
 
 ! 2007-09-25 - Vanya Belyaev
  - Patch #1357.
    Minor improvements to Gaudi::Utils::setProperty():
     - allow to set the documentation of a property
     - allow to set a property from a PopertyType
 
 ! 2007-09-24 - Sebastien Binet (& Marco Clemencic)
  - patch #1247. (partial)
    - avoid duplication of symbols in files generated by genconf.
      (Warning: Win32 implementation missing)
    Note: the patch was providing a patched version of genmap which cannot be
          included in Gaudi, but should be proposed to ROOT.
 
 ! 2007-09-24 - Hubert Degaudenzi
  - changed back Configurables.py into Configurable.py (it was
    a mistake).
 
 ! 2007-09-24 - Marco Clemencic
  - modified the way to pass  fallback module to genconf: comma-separated list
    instead of a dedicated option.
 
 ! 2007-09-24 - Markus Frank
  - fixed bug #29806. Wrong call to setDataProvider.
 
 ! 2007-09-21 - Hubert Degaudenzi & Marco Clemencic
  - factored out the main application part to the Gaudi package.
  - added the GaudiKernel prefix when importing python modules in order
    to avoid local imports.
  - changed the name of Configurable.py into Configurables.py for
    compatibility with the Athena module.
  - added an option to genconf that adds a fallback module for the
    location of Configurables and ConfigurableDb
  - modified the genconfig CMT pattern for the previous change to have
    AthenaCommon by default and if it doesn't exist fall back to
    GaudiKernel. This is a temporary fix until both approaches are merged.
 
 ! 2007-08-31 - Hubert Degaudenzi & Paolo Calafiura

  - patch #1231.
    - Splitted IChronoStatSvc.h into IChronoSvc and IStatSvc.
    - Remove ICounterSvc::CountObject and replaced it with Stat.
    - Added few free functions to format StatEntity objects as table rows.
 
 ! 2007-07-27 - Marco Clemencic
  - Added the file cbrt.h, which provides an implementation of cbrt (cubic
    root) to all the platforms (it is a built-in function of gcc).
 
 ! 2007-07-24 - Vanya Belyaev
  - patch #1246.
    Introduced 2 new classes:
      * Gaudi::Guards::ExceptionGuard
        executes a functor in a "standard" try-catch block.
      * Gaudi::Guards::AuditorGuard
        executes a function of an object when the instance is created and
        a second one when destroied, allowing automatic "clean-up" (in case
        of early exit).
    See GaudiKernel/Gaurds.h (doxygen) for more details.
 
 ! 2007-07-24 - Charles Leggett
  - patch #1253.
    This patch fixes Algorithm.cpp, AlgTool.cpp and Service.cpp such that
    there is a consistent use of the auditorSvc-after[whatever] in the catch
    loops when an exception is thrown. It also gets rid of some needlessly
    verbose comments.
 
 ! 2007-07-24 - Pere Mato

    Removed the default constructor of Service because it is causing a memory
    leak in Reflex.

 ! 2007-07-17 - Sebastien Binet
  - patch #1182.
    Improved precision for timing measurements in ProcessDescriptor
    (on linux).  The patch allow to use the function getrusage when
    possible to get a us precision instead of ms. When getrusage cannot
    be used, the timing is measured in the old way.
 
 ! 2007-07-16 - Marco Clemencic
  - changed the syntax for specialization of templated function in namespace 
    for gcc 4.1 future use
    
 ! 2007-07-16 - Hubert Degaudenzi
  - added the possibility to use the universal time for the messages.
    there is a new "%u" format for this. It replaces the usual "%t" in 
    the MessageSvc.Format.
 
 ! 2007-06-18 - Vanya Belyaev
  - patch #1178. 
     * The patch substitute the internal counters, used for
       (I)CounterSvc by generic counters of type StatEntity.
     * This allow to reuse the useful functionality of StatEntity class.
     * In addition it will allow an easy publishing and integration of
       counters with monitoring tasks.
     * Also it adds more functionality for grouping of counters, in
       particular the extraction of the whole group of counters
       (required by Matt Needham)
     * The printout of counters is now coherent with printout of
       generic counters through GuadiCommon<T>.
 
 ================ GaudiKernel v23r0 ====================================
 ! 2007-06-11 - Sebastien Binet
  - Fix to bug #26919. Explicit implementation of the copy constructor
    and assignment operator for the PropertyWithValue class.
 
 ! 2007-05-24 - Pere Mato
  - Added specialization of ROOT::Reflex::TypeDistiller for strings in
    AudFactory.h (was missing).
 
 ! 2007-05-24 - Marco Clemencic
  - Extended the IIncidentSvc interface to make it possible to register
    a listener for only one occurrence of the requested event
    (see bug #25552).
 
 ! 2007-05-24 - Vanya Belyaev
  - patch #1171. The enhancement of existing Algorithm Context Service
    is the primary goal of the proposed patch. The existing
    AlgContextSvc is not safe with respect to e.g. Data-On-Demand
    service or to operations with subalgorithms. The patched service
    essentially implements the queue of executing algorithms, thus the
    problems are eliminiated. In addition the enriched interface
    provides the access to the whole queue of executing algorithms.
 
 ! 2007-05-24 - Vanya Belyaev
  - patch #1163. Patch to allow the following syntax:
          setProperty ( "OutputLevel" , "4" ) ;
          setProperty ( "OutputLevel" , 4 ) ;  //new
          setProperty ( "Enable" , "False" ) ;
          setProperty ( "Enable" , false ) ; //new
          setProperty ( "ErrorMax" , "10" ) ;
          setProperty ( "ErrorMax" , 10 ) ; //new
          std::vector<double> data = ... ; //new
          setProperty( "Data" , data ) ; //new
          std::map<std::string,double> cuts = ... ; //new
          setProperty( "Cuts" , cuts ) ; //new
          std::map<std::string,std::string> dict = ... ; //new
          setProperty( "Dictionary" , dict ) ; //new
    The setting of properties through strings is still possible.

     - Removed "weight"-related functions and methods (unused)
     - Added binomial error calculation for efficiency-like counters
     - Improved print-out format
     - Added methods to make StatEntity mode DIM friendly
     - Some clean up in comments

     * ParseVectorsChar.cpp
     * ParseVectorsInteger.cpp
     * ParseVectorsReal.cpp
     * ParseVectorsString.cpp
     * ParseVectorsVector.cpp
    to reduce memory usage at compile time (with a modest increase of
    disk space and compilation time).
 
 ! 2007-05-15 - Sebastien Binet
  - patch #1157. Here is a simple patch to harmonize the interaction
    with the underlying m_outputLevel data member of each of these main
    Gaudi components. It makes sure that the 3 of them have:
         int outputLevel () const;
         void initOutputLevel(Property&); //update handler
    also added this method to MsgStream:
         void setMsgSvc( IMessageSvc* svc ) {
              m_service = svc;
         } 
 
 ! 2007-05-15 - Chris Jones

    monitoring service
   + Addition of the same declareInfo(...) methods in AlgTool as in
     Algorithm
   + Replace hardcoded monitor service name with new job option
   + New method to provide 'easy' direct access to monitor service
     via pointer

 ! 2007-05-14 - Marco Clemencic
  - fix to bug #25852 bis
    Fixed compilation problem on windows by adding the definitions for
    the missing functions localtime_r and gmtime_r
    (header GaudiKernel/time_r.h).
    Removed also a couple of compilation warnings.
 
 ! 2007-05-10 - Ivan Belyaev 
  Patch #1126: 
  - GaudiKernel/StatEntity.h, src/Lib/StatEntity.cpp
    1) Add the assignment operator from the scalar value according to
       the request by Ulrich Kerzel (LHCb/RICH)
    2) Add two new methods "efficiency" and "efficiencyErr" for
       evaluation of binomial estimate of the efficiency, associated
       with the counter. If the counter could be interpreted as
       efficiency, these methods produce right results. Method
       "efficiency" returns either "flagMean" or -1, if the
       interpretation of counter as efficiency is not possible. In a
       similar way "efficiencyErr" returns the binomial estimate of the
       uncertainty or -1, if the interpretation of counter as
       efficiency is not possible. Note that there could be sizable
       difference between RMS estimate "flagMeanRMS" and the binomial
       estimate "efficiencyErr", however for large statistics and for
       non-extremal (close to ~0 or, especially ~100%) efficiencies,
       these estimates should be very similar.
  - GaudiKernel/ToStream.h
    1) Add the printout for std::list
    2) Add the template parameters for std::vector, std::set, std:map,
       GaudiUtils::Map, GaudiUtils::VectorMap, GaudiUtils::HashMap. It
       allows to use all these function for containers with non-default
       optional template arguments, e.g. allocators, comparison
       criteria, hash functions or underlying containers,
    3) Remove the unused local variable "delim".
  - GaudiKernel/VectorMap.h, GaudiKernel/Map.h. Improve doxygen
    comments according to the request by Marco Cattaneo)
 
 ! 2007-05-10 - Hubert Degaudenzi

    destructors in NTuple.h for NTuple::Array, NTuple::Matrix,
    NTuple::Item etc.
 
 ! 2007-05-09 - Sebastien Binet
  - patch #1141. Fix return statement of GaudiHandleArray::operator=.
 
 ! 2007-05-02 - Hubert Degaudenzi
  - fix to bug #25460. The return value of getLastError is now an
    unsigned long. A static_cast was added.
 
 ! 2007-04-30 - Andy Salnikov
  - fix to bug #25852. The patch is quite small and touches only two
    classes - Message and MessageSvc. Messages now have one more format
    flag '%t' which is replaced with the formatted timestamp on
    output. Default format string has not changed so default output
    will look identical to what it was before. The format of the
    timestamp can be changed through the additional format string
    similarly to the message format string. Time format can contain
    anything that is accepted by strftime plus additional '%f' code for
    milliseconds.
 
 ! 2007-04-27 - Sebastien Binet 
  - patch #25888. Fixed uninitialized variable in Algorithm.cpp.

    IInterfaceID. An empty virtual destructor has been added.
 
 ! 2007-04-05 - Martin Woudstra
  - Patch #1103. The attached 2 patches (one for GaudiPython and one
    for GaudiKernel) contain the changes needed to support
    ToolHandleArray's (a 'vector' of ToolHandles). This is a new
    feature, and is already in use in ATLAS. In addition to the
    ToolHandleArray and its associated base classes, there is the
    GaudiHandleArrayProperty, and an update to genconf to support it
 
 ! 2007-03-25 - Chris Jones
  - Patch #1099. Add Specialization stream operator for
    std::vector<T,A> to MsgStream.h Allows print out of vector created
    with custom allocators e.g. std::vector< RichSmartID,
    boost::pool_allocator< RichSmartID > >
 
 ! 2007-04-04 - Chris Jones
  - Patch #1092. There is a bug in the current implementation of the
    format(..) method in MsgStream.(cpp,h) which means if a user uses
    the format method twice in one message request, wrong information
    is printed. The attached patch fixes this by returning instead a
    std::string.  However, if somewere a user is explicitly using the
    returned char * pointer (They really shouldn't be...) a small
    change to their code would be required. i.e.
       char * c = format("XXX,x);
       to
       std::string s = format("XXX,x);
       c = s.c_str();

    the destinatin file of genconf has a "+" in its path.
 
 ! 2007-03-13 - Sebastien Binet
  Patch #1080: fixes to GaudiKernel/src/Util/genconf.cpp:
  - fix handling of templated components
  - fix handling of (default value of) BooleanProperties
  - fix handling of NaN DoubleProperties (follows the good old Garbage
    In, Garbage Out pattern, even though a warning is issued during
    genconf processing...)
 
 
 ! 2007-03-12 - Vanya Belyaev
  - Patch #1073. Simple modification of IExceptionSvc interface (and
    the implementation ExceptionSvc) to avoid the explicit appearence
    of class Algorithm in the interface. The interface is modified to
    substitute Algorithms with INamedInterface. It allows to use the
    service in much wider context, in particular with tools, services
    and auditors.
 
 ! 2007-03-9 - Sebastien Binet
  - Patch #1058 (partially). Makes sure a DoubleProperty is understood
    as a double on the python side (and not converted into an int as it
    was the cast)
  - added merge_genconfDb.py scripts to merge configurables.
 
 ! 2007-03-9 - Hubert Degaudenzi
  - Clean up genconf pattern left over.
 
 ! 2007-03-08 - Martin Woudstra
  - patch #1070. The python configurables generated with the current
    genconf.cpp return the python (mangled) class name from the
    function getType(). This should be the C++ class name, otherwise
    the ToolSvc will not find tools from classes in namespaces and/or
    templated classes. This is critical as many classes in ATLAS as of
    these categories and all those are broken now.
  - patch #1071. The GaudiHandle version used in ATLAS has since some
    time an 'empty()' member function to indicate that no component is
    supposed to be retrieved nor used. For some reason this member
    function did not make it into Gaudi 19, so now the ATLAS code is
    broken. patch adds this member function to the GaudiHandleBase
    class, and allows the users to specify an 'empty' handle in the
    constructor (i.e. "" is kept is-as and does not trigger the setting
    to the default type).

 ! 2007-02-15 - Marco Clemencic
  Patch 1032:
  - Added a helper class to allow the usage of IUpdateManagerSvc from
    python.  The helper class is IUpdateManagerSvc::PythonHelper,
    declared as friend of IUpdateManagerSvc. The implementation
    consists of 2 static functions implemented in dictionary.h.

       only from Algorithm, Services and AlgTools, but also from
       Auditors.
    b) Update the queryInteface method for AlgTool,Algorithm,Auditor

 ! 2007-02-08 - Pere Mato (David Quarrie)
  - Bootstrap.cpp:
    Introduced a dual-stage boostrap mechanism to ensure an orderly startup
    of the ApplicationMgr. If the Gaudi::svcLocator() function is called before the singleton
    ApplicationMgr instance exists, a BootSvcLocator singleton instance is
    created. This responds to any subsequent requests for services by
    returning StatusCode::FAILURE, unless the ApplicationMgr singleton 
    instance has been created in the interim. In this case, the BootSvcLocator
    forwards the request to the ApplicationMgr instance. The motiviation for
    this is to handle static object instances where the constructor attempts
    to locate services and would otherwise instantiate the ApplicationMgr
    instance in an unorderly manner. This logic requires that the 
    ApplicationMgr instance is created explicitly.

    partial spec operator << (vector<T>&) into open functions. This
    appears to remove ambiguities a user defined MsgStream operator <<
    template (typically in a data object header file). The compiler
    sees the user defined template as a better specialization and
    matches that with no ambiguity.

 ! 2006-11-29 - Hubert Degaudenzi
  - this is the beginning of the release notes for the merge with the
    v20r13 release (v20r9b branch).
 
 ! 2006-11-26 - Vanya BELYAEV - patch #922
  - GaudiKernel/VectorMap.h
     1) On the request form ATLAS (Savannah reports  #21395 and #21394)
        add the method "update" to class GaudiUtils::VectorMap.
        NOTE: It is nor STL-compliant! 
        It behaves like "insert", but it OVERRIDES the mapped value 
     2) Also  "const-look-up" is added through the methods 
        "operator()" and "operator[]" 
        Again it is nto STL-complient signature: 
        the methdod are "const" , and there are no 
        "non-const" analogues 
 
      *  For typical usage of this class in LHCb context 
      *  as "ExtraInfo" field I would like to recommend 
      *  to AVOID this method 
  
     3) Add also the checked access in STL-spirit: 
         GaudiUtils::VectorMap::at   
        throw std::out_of_range exception for non-existing keys 
  - GaudiKernel/ToStream.h
     add the partial specialization for printout of following classes:  
      1) GaudiUtils::Map   
      2) GaudiUtils::HashMap   
      3) GaudiUtils::VectorMap
     The printout done in a style of "Python-dictionary", similar to 
      std::map 
     Also print out for std::set is added 
  - src/Lib/VectorMap.cpp
      new file fith implementtation of action for nonexisting key 
 
 ! 2006-11-22 - Hubert Degaudenzi
  - added environment variable GCCXML_CXXFLAGS=" -m32" for 32 bits
    compilation on amd64 machines (with the slc4-ia32 tag)
  - added environment variable GAUDIEXE which points to the Gaudi
    executable.
 
 ! 2006-11-02 - Hubert Degaudenzi
  - modified rootmapdump.py in order to match any file *beginning* with
    "rootmap" and not only the "rootmap" filename. This is the same
    matching behavior as the one in ROOT itself.
 
 ! 2006-10-27 - Ivan Belyaev
  - patch #870. Added operator << for StatusCode.
 
 ! 2006-10-26 - Marco Clemencic
  - Patch #736. Improvemts to TransientFastContainer. Now it allows to
    use for new objects the default constructor, the copy constructor
    and a user specified constructor (via placement new).
 
 ! 2006-10-12 - Marco Clemencic
  - Patch #879. Fixed a bug in DataSvc. When retrieving an object from
    the transient store, it fails if the root node has not yet been
    loaded. I added a check on the root node for those cases and I
    explicitely load it if needed.
 
 ! 2006-10-06 - Marco Clemencic
  - Patch #863. Add the function System::setEnv to set an environment
    variable.  Setting the variable to "" results in removing it from
    the environment (same behavior on windows and linux). The parameter
    overwrite define the behavior in the case the variable is alredy
    present (0=no change, 1=overwrite).
 
 ! 2006-11-29 - Hubert Degaudenzi
  - this is the end of the release notes for the merge with the
    v20r13 release (v20r9b branch).
 
 ! 2006-11-27 - David Quarrie
  - fixed compilation problems for MacOS 10.4
 
 ! 2006-11-17 - Pere Mato
  - ISvcLocator.h: Added new function eraseService() to erase a service
    from the list of known services
  - Service.cpp: The destructor calls eraseService() to cleanup the
    service list
  - Minor corrections for StatusCode.
 
 ! 2006-11-10 - Markus Frank -Patch #908
  - Removed access to histogram factory.
  - Added storage types for online usage to CLID.h
  - new header HistogramBase.h to allow access to ROOT implementation
    of AIDA histograms.
 
 ! 2006-11-09 - Pere Mato
  - Added classes JobHistory, AlgorithmHistory, AlgToolHistory,
    DataHistory, ServiceHistory from "GaudiHistory" package such that
    it can be removed. The goal is to have less packages
    (i.e. complexity)
  - requirements: added pattern to generate Python configuration file
  - genconf.cpp: adapted to new properties
 
 ================ GaudiKernel v21r0 ====================================
 ! 2006-10-31 - Pere Mato
  - StatusCode.h(.cpp) - Reworked to avoid copying complicated objects
    all the time
 
 ! 2006-09-25 - Hubert Degaudenzi
  - added the scripts folder with the rootmapdump.py utility. This
    scripts allows to dump the ROOTMAPs present in the
    LD_LIBRARY_PATH. It can also check the duplication of entries.
 
 ! 2006-09-21 - Hubert Degaudenzi
  - factored out the stacktrace function from the StatusCode class to the
    System.cpp file.
 
 ! 2006-09-09 - Hubert Degaudenzi
  - added dictionary generation for ExceptionSvc, IssueLogger,
    StatusCodeSvc, THistSvc.
  - fixed compilation problem for win32 in the StatusCode.cpp file.
 
 ! 2006-09-09 - Charles Leggett & Hubert Degaudenzi
  - Imported new services interfaces from ATLAS: IExceptionSvc,
    IIssueLogger, IStatusCodeSvc, ITHistSvc.
  - StatusCode.h has been modified (and has now an implementation)
  - new IssueSeverity.cpp.
 
 ! 2006-09-09 - Vanya BELYAEV - patch #839
  - GaudiKernel/Grammars.h
      Add a method StringGrammar::matchString, which allows to 
      substitute all "std::isspace" symbols with the blank.
      It is a bit incorrect operation, but it allows 
      to split very long string into few lines.
      It is incorrect since the overall number of blank symbols 
      in the string is a quantity which is difficult to control.
      One still needs to be very careful with CR/LF symbols in the 
      opts-files. 
      This particular fix solves the problem with configuration
      of DataOnDemandSvc, where long string are unavoidable. 
      The solution  ( 'std::isspace' --> ' ' ) has been discussed with 
      Marco Cattaneo. We have agreed that this solution is not safe, 
      but it solves the particular problem. 
 
      The fix is kindly provided by Sasha Mazurov (Alexander.Mazurov@gmail.com)
 
  - GaudiKernel/Property.h 
     1) reshuffle the property assignment/load methods to eliminate the 
        duplication of actions, from now Property::load is implemented 
        through Property::assign. It provides a bit more coherency in 
        the code.
     2) the actual action for Property::assign and Property::load is 
        been released a bit, not one can load/assign either from the 
        property of the same type or from the valid string representation 
        of property of any type. Previously only StringProperty has been 
        allowed.
     3) The full template specializations of 
        PropertyWithValue<std::string>::toString and  
        PropertyWithValue<std::string>::assign are provided 
         - there are no "extra" confusing double quotes now in the 
           string printout 
         - the string is always parsed at assign, in particular it means
           that all surrounding pairs of quotes will be removed 
           automatically as redundant  
  - GaudiKernel/ToStream.h
       - modify a bit the implementation of Gaudi::Utils::toStream 
         for std::string to use single quotes if the string containt 
         double quotes
       - add the implementation of Gaudi::Utils::toStream for boolean values 
         to print boolean values "à la Python" as "True" or "False" 
       - add the implementation for float/double/long double to print them 
         with reasonable precision. It is important since the default 
         precision of ios_base is 6, which could be not enough, and 
         the precision of boost::lexical_cast is 
          std::numerical_limit<...>::digit10+1, 
         which is much more than we need.
   - GaudiKernel/Property.h, src/Lib/Property.cpp 
      add few useful functions to descrease the number of ugly  
      technical lines in some public code 
 
      namespace Gaudi { namespace Utils {
        bool      hasProperty ( const IProperty*  p  , const std::string& name ) ;
        bool      hasProperty ( const IInterface* p  , const std::string& name ) ;
        Property* getProperty ( const IProperty*  p  , const std::string& name ) ;
        Property* getProperty ( const IInterface* p  , const std::string& name ) ;
        bool      hasProperty 
        ( const std::vector<const Property*> , const std::string& name ) ;
        const Property* getProperty 
        ( const std::vector<const Property*> , const std::string& name ) ;
      
      }}
 
 ================ GaudiKernel v20r9 ====================================
 ! 2006-08-21 - Ivan Belyaev
  - patch #817. For new associatiove properties, e.g. map
    the implemented behaviour do not fulfill the naive expectations. E.g:
 
    A.a = { "a" : 1 , "a" : 2 , "b" : 3 , "a" : 10 } ; 
    A.a += { "a" : 100 , "a" : 200 };
 
    The result will be the map:
 
    { "a" : 1 , "b" = 2 } ; // "The first wins"
 
    this result is not in agreement with "naive" expectation for
    std::map, where "the last wins". the attached patch solves the
    problem, and now the behaviour of the properties is more coherent
    with behaviour of std::map.
 
 ! 2006-08-06 - Markus Frank
  - System.cpp: do not free strings after calls to strerror() or
    dlerror().  This is known to cause valgrind errors because libc
    internally allocates memory, but is the **correct** usage of these
    functions according to the docs. Otherwise repeated calls tend to
    screw up malloc.
  
 ! 2006-07-31 - Pere Mato
  - Changed interface IJobOptionsSvc from pointer to reference to fix
    bug #18581 overview: Memory leak due to changed behaviour of
    JobOptionsSvc
 
 ================ GaudiKernel v20r8 ====================================
 ! 2006-07-14 - Stefan Roiser
  - fixed type in dictionary for m_typeinfo member of the Property
    class in the xml selection file.
 
 ! 2006-07-07 - Hubert Degaudenzi
  - bug #17843: fixed extra semicolon and DOS end of lines.
 
 ! 2006-07-07 - Marco Clemencic
  - patch #748: fixed the recipient of the std::string::find method. It
    should not be assigned to int but to std::string::size_type since
    it has a different size on 64 bits plateforms.
 
 ! 2006-06-26 - Hubert Degaudenzi
  - bug #17739. Changed the return value of GaudiMain. Before it was always
    returning 0 and now it returns the StatusCode of the ApplicationMgr
    in the UNIX command line way.
       - "0" for success
       - "1" for failure
    to test it for examples one could do: 
      >Gaudi.exe some.opts && echo "Gaudi has succeeded"
 
 ! 2006-06-15 - Hubert Degaudenzi
  - Fix gcc 3.4.5 compilation problems in the new property parser. 
 
 ! 2006-06-06 - Alexander Mazurov & Ivan Belyaev
  - new property parser installed. It relies on the Boost::spirit
    lexer/parser.
 
 ! 2006-06-06 - Vanya Belyaev
  - fixed const problem in VectorMap.
 
 ! 2006-05-31 - Marco Clemencic
  - patch #730. Fixes a bug in the constructor of
    TransientFastContainer when it is called with an argument different
    from 0.
 
 ================ GaudiKernel v20r7 ====================================
 ! 2006-05-22 - Marco Clemencic
  - patch #727. Fixed a compilation problem on Win32 after using
    std::map instead of hash_map in GaudiUtils::HashMap.
 
 ! 2006-05-19 - Marco Clemencic
  - patch #725. Fixed a warning on Win32.
 
 ! 2006-05-11 - Marco Cattaneo
  - patch #723. Redefines the unit "pascal" to "Pa" to avoid a name
    clash that causes a compiler warning on on Windows in
    SystemOfUnits.h
 
 ! 2006-05-11 - Vanya Belyaev
  - added templated SmartRefVector constructor with first and last
    iterator pointers as arguments 
 
 ================ GaudiKernel v20r6 ====================================
 ! 2006-05-04 Marco Clemencic
  - patch #720. Added TransientFastContiner<T> (and related helper classes
    TransientFastContainerBase and DefaultObjectCleaner<T>).
    The new container does its own memory management, recycling the objects not
    used and not deleting them when it is cleared (just reset an internal
    counter).
 
 ! 2006-05-02 Hubert Degaudenzi
  - Added PhysicalConstants.h and SystemOfUnits.h (from CLHEP) in
    GaudiKernel. The constants and units are in the Gaudi::Units
    namespace. 
  - patch #715. Added boost allocator wrapper (Marco Clemencic).
  - patch #719. Added 2 functions to make the UpdateManagerSvc work
    safely in multi-thread environment. They allow to block the
    activities of the service while interacting with it (Marco Clemencic).
 
 ! 2006-04-20 Hubert Degaudenzi
  - clean up of the legacy lines of code for obsolete compiler version
   (before gcc 3).
 
 ! 2006-04-20 Marco Clemencic
  - patch #705. The default hash functions is extremely expensive for
    integers. This causes extremely poor performaces for the standard
    KeyedContainer<>. The patch introduces efficient specializations of
    Hash<> for int, long and long long (and unsigned).
 
 ! 2006-04-13 Charles Leggett and Hubert Degaudenzi
  - inserted ATLAS feature INamedInterface.
 
 ================ GaudiKernel v20r5 ====================================
 ! 2006-03-15
  - modified the returned values of the Auditors
    beforeExecute/afterExecute (etc) to be void instead of StatusCode::SUCCESS.
 
 ! 2006-03-09 Markus Frank
  - patch #691. Add support for objects in N-tuples. Note: This only works for
    NTuple::Item.  NTuple::Array and NTuple::Matrix is __NOT__
    supported for objects. If you need this functionality store an
    std::vector<Object*>. See GaudiExamples/POOLIO/EvtCollectionWrite
    for an example of the usage.
  - Added GaudiMain.cpp in the library.
 
 ! 2006-03-09 Markus Frank
  - patch #668. Fix retrieval of error string in System::getErrorString().
    The routine caused a core dump on linux when dl_error() returned NULL.
 
 ! 2006-02-24 Marco Clemencic
  - patch #678. It has been reported that MS implementation of hash_map
    is extremely slow. The idea is to use std::map instead (which is
    faster than hash_map on win!!!), while we investigate to find a
    better solution.
 
 ! 2006-02-23 Hubert Degaudenzi
  - fix compilation warnings with Gcc 3.4.4
 
 ! 2006-02-14 Ivan Belyaev
  - added new allocator imported from GEANT4. They should decrease the
    allocation time significantly. Please have a look at the
    GaudiExample "Allocator".
 
 ! 2006-02-06 Hubert Degaudenzi
  - fixed windows compilation warning (bug #14852).
 
 ================ GaudiKernel v20r4 ====================================

  - Moved some class in the dictionary of GaudiPython to the dictionary in GaudiKernel
  
 ! 2006-01-25 Marco Clemencic
  - Added class Gaudi::Time (based on seal::Time). Updated interfaces
    IDetDataSvc, IValidity and IUpdateManager in order to use the new class.
    Modified dictionary.h and dictionary.xml in order to produce dictionaries
    for Gaudi::Time.
 
 ! 2006-01-25 Hubert Degaudenzi
  - added IUpdateManagerSvc in the dictionary generation.
 
 ! 2006-01-19 Pere Mato
  - Adapted to use genreflex (Reflex from ROOT)

 ! 2006-01-18 Hubert Degaudenzi
  - fixed forward declarations in GaudiKernel/IMagneticFieldSvc.h
 
 ! 2006-01-12 Pere Mato
  - Added std::vector<const ContainedObect*> in the dictionary
 
 ! 2006-01-10 Hubert Degaudenzi
  - moved the macro definitions DECLARE_XXX_FACTORY and
    DECLARE_NAMESPACE_XXX_FACTORY from DeclareFactoryEntries.h to their
    own header files where XXX are Algorithm, Auditor, Converter,
    Object, Service, Tool.
  - corrected wrong syntax in macros.
  - moved the remaining macros (DECLARE_XXX and DECLARE_NAMESPACE_XXX)
    from DeclareFactoryEntries.h to their corresponding header files.
 
 ! 2005-12-20 Hubert Degaudenzi
  - Commented out AIDATupleSvc.
 
 ! 2005-12-20 Marco Clemencic
  - Added UpdateManager interface.

  - added setCriteria method to IAIDATupleSvc interface to allow passing
    a preselection criteria for reading data from a tuple.
 
 ! 2005-11-15 Markus Frank
  - Fix problems of KeyedContainer when using keys with explicit constructors.
 
 ================ GaudiKernel v20r2 ====================================
 ! 2005-11-22 Pere Mato
  - Booststrap.h: converted Gaudi class into a Gaudi namespace
 
 ! 2005-11-22 Vanya Belyaev
  - Added class GaudiUtils::VectorMap (former _VctMap from Vanya) that implements associative version inspirer 
    from the Loki library by Andrei Alexandrescu.
  
  an associative vector
    inspired from Loki associative vector.
    Fix problems of KeyedContainer when using keys with explicit constructors.
 
 ! 2005-11-21 Markus Frank
  - Fix problems of KeyedContainer when using keys with explicit constructors.
 
 ! 2005-11-21 -  Pere Mato
   - Added new methods in IAlgorithm: isInitialized(), isFinalized() and isExecuted() (suggested by Vanya)
 
 ! 2005-11-18 -  Marco Clemencic
   - Added 3 classes to replace the HashTable and the hacks in stl_hash.h
   
     * GaudiUtils::Map is a simple associative container. It is implemented as a proxy 
       to a template class implementing the underlying container (defaulting to std::map). 
       It features "operator[](key) const" and "operator()(key) const". It has a virtual 
       destructor so that it can be extended via inheritance.
     * GaudiUtils::Hash is a simple hash function (based on Stroustrup's example) which 
       correctly handle pointers, std::string and char*. It is portable between Linux and Windows.
     * GaudiYUtils::HashMap is a Map which uses internally a hash_map. The differences 
       between gcc and VC7 are taken into account in order avoid users having to put "#ifdef"s.
 
 ! 2005-11-09 - Chris Jones
  - Change output level data member in Algorithms and AlgTools from int
    to IntegerProperty, and add a non-const access method for this
    property. Allows uses to attach callback handle methods to this
    property (Such as in GaudiAlg) to allow them to react as needed
    to changes in the output levels. Needed in GaudiAlg to force the
    creation of a new cached MsgStream object.
 
 ================ GaudiKernel v20r1 ====================================
 ! 2005-11-03 Pere Mato
  - added the changes to dictionary.xml delection file. Removed the dictionary_rflx.xml file.

    KeyedObject in the dictionary_rflx.xml selection file (Markus Frank).
 
 ================ GaudiKernel v20r0 ====================================
 ! 2005-09-12  Pere Mato
  - MsgStream.h: removed special stream function for StatusCode. It did
    not help on WIN32
  - GaudiException.h: added explicit call to accessor of StatusCode to
    unsigned long code
 
 ! 2005-08-05  Hubert Degaudenzi
  - added "long long" format in the instantiation of SimpleProperty and
    SimplePropertyRef templates.
 
 ! 2005-08-05  Hubert Degaudenzi
  - applied patch #502. Minor polishing of Stat and StatEntity classes
    to improve their functionality (in absolutely backward compatible
    way). From now the usage of StatEntyty in 'standalone' mode is
    greatly simplified (previously it has been tightly coupled to
    Chrono&Stat Service, and "public" interface was ugly). The
    functionality of Stat class is also improved (Vanya).

    hence problem did not appear)
  - Fix data member access in RndmGenerators.h
 
 ! 2005-07-21 Hubert Degaudenzi
  - patch #476. Compilation of some Reflex dictionaries currently
    fails. I'd need an overload for the MsgStream::operator << for
    StatusCode to cure this. The attached patch is one proposal how it
    could be done (Stefan Roiser).

 ! 2005-02-25 - Pere Mato
  - System.cpp: applied patch to overcome CXXABI problem (merge from v17r1)
  
 ! 2005-02-24 - Manuel Domenech
 - Added the interface IAIDATupleSvc.h for the AIDA-based tuple service.

 ================GaudiKernel v18r2=====================================
 ! 2005-02-15 - Markus Frank
  - SealDictionary.h - fix for SmartRefDict. 
 
 ! 2005-02-11 - Pere Mato
  - Algorithm.cpp: removed the name extensions such as  ".sysInitialize()", ".sysExecute()" 
    and ".sysFinalize()" in the messages generated by the base class.
    It makes it simple to control over the threshold messages from algorithm. (suggested by Vanya)
 
 ! 2005-02-02 - Pere Mato
  - System.cpp(typeinfoName):  removed extra spaces between types and "*" and "&"
 
 ================GaudiKernel v18r1=====================================

  - Algorithm.h,.cpp: Added new method declateInfo(...) to declare monitoring variables
  
 ! 2004-12-06 - Markus Frank
  - SealDictionary.h
    Make use of ReflectionBuilder/CollectionProxy.h
    for new container handling using ROOT CollectionProxy mechanism.
  - Service.cpp:
    Inhibit printing of services before the properties are properly
    set. Until the properties are set, each service inherits the
    output level of the message service.
    This was apparently screwed with the invention of the
    OutputLevel update handler for services.
    This removes the "ignored" global printout level of the
    sub-eventselector instances when opening new files.

     Fixed Feature: For smart refs to ContainedObject(s), resolve
     parent pointer only when needed.
   - ConversionSvc.cpp:
     Bug fix: Converters were never finalized. Done from now on, whenever the
     converter gets disconnected from the conversion service.
     
 ================v11r0=====================================
 ! 20011212 - Pere Mato
   - Added dependency to AIDA requested by David Quarrie
 
 ! 20011207 - Sebastien Ponce
   - Changed interface IConversionSvc.h. Added method converter(const CLID&) to get
     the converter with that CLID.
 
 ! 20011126 - Markus Frank
   - MsgStream.cpp
     Any change of the printout level from the application program
     using MsgStream::setLevel(...) is ignored by the message service. 
     Update the local printout level on a by message bases and restore
     the previous printout level.
 
 ! 20011120 - Markus Frank
   - NTuple.h
     the function entries addItem(...) are DEPRECATED for
     Ntuple columns, which depend on an index column.
     The replacement is: addIndexedItem(...).
     This has repeatedly caused confusion for users.
     Also added doxygen information for these entries.
 
 ! 20011115 - Pere Mato
   - Added initialize() and finalize() methods in IAlgTool interface.
   - The base class AlgTool implemements them as dummy but allows an implementation
     of  them on specific Algorithm Tools
   - Removed the need to implement a queryInterface() in specific Algorithm tools. Instead
     use the expresion declareInterface<Ixxxx>(this) in the constructor.  
   - Added releaseTool() method in IToolSvc.
  
 ! 20011111 - Pere Mato
   - Many Changes from Markus for the DataStore classes re-design.
 
 ! 20011108 - Pere Mato
   New versions of interfaces:
   - ISvcManager.h (incompatible) Added more functionality to offload ApplicationMgr
   - ISvsLocator.h (compatible) Changed getServices() to const
   
 ! 20011105 - Sebastien Ponce
   Added new methods in DataSvc to be able to set the root without clearing
   the store
 
 ! 20011009 - Pere Mato
   Removed CLID_Event from ClassID.h to avoid clashes with Event.h generated from
   GaudiObjDesc tools
 
 ! 20011005 - Pere Mato
   Changed IInterface.h Introduced a new constructor for InterfaceID that
   uses a name (class name) instead of the interface number. A hash
   function converts the name into a number.
 
 ! 20011003 - Pere Mato
   Changed SmartDataLocator.h reported by David Rousseau
 
 ! 20010914 - Pere Mato
   Modified ClassID.h to include CondDB stuff
   Solved bug in DataSvc.cpp reported by Andrea Valassi
 
 ! 20010710 - Pere Mato
   Removed interfaces IGiGaSvc.h and IGiGaSetUpSvc.h
 
 ! 20010706 - David Quarrie
   Extend IChronoStatSvc to support retrieving the delta-time between
   start/stop pairs.
 
 ! 20010629 - Pere Mato
   Changes in interfaces needed for improved interactivity support :
   IService.h   : Added new method reinitialize() to allow services to 
                  take into account changes after the first time initialization
   IAlgorithm.h : Added beginRun() and endRun() methods. These are called each time
                  the event loop is executed.
   IEventProcessor.h : Added executeRun() and nextEvent() methods. This is to 
                       eliminate the need to use the IAppMgrUI interface in the
                       EventLoopMgr components.
   IAppMgrUI.h  : Renamed method state() to stateName().
   IScriptingSvc.h : Deleted
 
 ! 20010627 - Markus Frank
   Bootstrap.h/cpp : Allow to set the instance of the service locator
                     in case several ApplicationMgr instances are present.
   ObjectVector.h,
   ObjectList.h    : Add forward typedefs for pointer and const_pointer
                     (Requested by P.Calafiura/LBL)
   RefTable.h      : Implement serialize methods
   RegistryEntry.h/cpp,
   DataSvc.h/cpp   : Implement several bug-fixes
                      - allow for objects in locations like /AA/BB/BB/BB/...
                      - allow to access objects with omission of the root
                        directory: "/Event/MC" is equivalent to "MC"
                      - execution optimization
   SmartDataObjectPtr.h : Fix annoying compiler warning
   SmartRefBase.h,
   SmartRef.h      : operator==() was badly implemented (Found by O.Callot)
   strcasecmp.h    : WIN32 needs an additional #include <cstring> 
 
 ! 20010625 - Pere Mato
   - Added remote properties functionality. Changed PropertyMgr and base classes Service
     and Algorithm
   - Added MsgStream::endmsg with same functionality as endreq. (Request from ATLAS)
   - Using AIDA Historams instead of LHCb private ones. The existing include files 
     include the new ones but generating a warning. The IAnnotation interface is added
     because it does not exists in the used AIDA release
     
 
 ! 20010618 - v10 (Flr)
   requirements - use GaudiPolicy v5
                  apply pattern package_stamps
 
 ! 20010518 - Pere Mato
   Changed CLIDs in Reftable.h (re-tagged v9)
 
 ! 20010508 - Pere Mato
   Fixed bug reported by M. Cattaneo. The OutputLevel of AlgTools was not
   set correctly if the parent Algorithm didn't set it explicitely.
 
 ! 20010503 - Markus Frank
   Allow access to data store items without specification of the top level
   directory. It is equivalent to specify an histogram like "/stat/simple/1"
   or simply "simple/1". Note that the the entire prefix "/stat/" must be 
   omitted. The use is backwards compatible.
   Added a qualifier ALWAYS to the message service specifying that a given 
   message should always be printed.
   ie.
   MsgStream log (msgSvc(), "Name")
   log << MSG::ALWAYS << "Hello." << endreq;
   will result in
   Name      SUCCESS Hello.
   and will not be omitted.

   Bug fixes:
   GaudiKernel/DllMain.icpp WINNT: Processhandle should no longer be closed
                            since the handle is shared for all DLLs.
   GaudiKernel/INTuple.h    Interface extended to directly use NTuple pointer
                            to write/read n-tuple. It is no longer necessary to

                                     if ( obj ) {...}
                                     Check succeeded if object is present however
                                     had bad type. Now this check checks for the

                                     Moved pointer to object from SmartDataObjectPtr
                                     to SmartDataStorePtr (template class).

  -@System:
        Major code reshuffeling.
         - Static class was changed to namespace. This will make it much simpler to
         extend the functionality without actually having the default header System.h.
         System.h containes the declarations of all functions in a backwards-compatible way.
       - All other functionality was factorized out:
         Memory.h/cpp            Info about memory consumption
         Timing.h/cpp            Info about time consumption
         ModuleInfo.h/cpp        Info about running modules
         Debugger.h/cpp          Invoke debugger from running program (NT only)
         ProcessDescriptor.h/cpp **Internal** access to process specific information
         + Win32Api.h            as it is exported by Linux/NT. This header is PURELY internal
                                 and should never be included directly.

  - Moved files ISolid.h, IPVolume.h, ILVolume.h, IDetectorElement.h, IGeometryInfo.h
    ITransportSvc.h to the DesDesc package. Forward links to the new position have been
    left in place.
 
 ! 20010312 Markus Frank
  Changes to the job options processing
  - implemented PropertyMgr::setProperty( const std::string& n, const std::string& v )
  - Properly implement the macro QUOTEDELEMENTINPUT.
    CTDay ir right when he quotes that this is "HACK Big Time". It's also undebuggable.

  - Corrected bug reported by O. Callot that the OutputLevel was not working
    for Algorithms.
 
 ! 20010228 David Quarrie
  - ARM page 210 tweaks to IToolFactory.h to avoid compiler warnings. Add
    DECLARE_ALGTOOL(X) and DECLARE_TOOL(X) macros to DeclareFactoryEntries.h
 
 ! 20010226 Pere Mato
  - Small changes to make it compile in NT
 
 ! 20010223 David Quarrie
  - Changes for Solaris support, which is incomplete. The package compiles on
    this platform, but some of the required template specialization "hacks" are
    not fully understood and need to be revisited. Run-time debugging hasn't
    yet begun.
  - Changes to avoid compiler warning messages. These are all due to function
    overloading across class hierarchies. The policy is described on Page 210
    of the ARM. It's not yet clear whether these are compatible with the Visual
    C++ compiler on NT. Modified files:
        GenericLink.h IAlgFactory.h IAuditorFactory.h IDataDirectory.h
        IFactory.h IHistogramSvc.h ISvcFactory.h ObjectContainerBase.h
        ObjectFactory.h ObjectList.h ObjectVector.h
  - Changes to support the scripting service. SimpleProperties now support
    callback handlers for both reading and updating. The IProperty interface
    has been extended to allow more flexible setting & retrieving of properties
    from streams and strings. Modified files:
        IProperty.h Property PropertyMgr PropertyVerifier
  - Add support for explicitly specifying the CLID and name of the root
    object in the transient event store (defaults are CLID_Event and "/Event").
    Modified files:
     DataSvc IDataManagerSvc
  - Other details:
    AlgTool Algorithm Auditor Service
        Support new IProperty interface. Use function template for
        declareProperty. Support deferred service instantiation in service
        accessors.
    FactoryTable.h
         Fix compiler warning because of missing comment characters
    System.cpp
         Minor tweak to avoid SOlaris compiler warning.

  - Corrected bug in Algorithm::service()
  - In Bootstrap.h, added static method Gaudi::svcLocator() to get the ISvcLocator* 
    in isolation.
  - In ISvcLocation.h added a templated method ISvcLocator::service() to facilitate 
    retrival of services.
 
 ! 20010122 - GaudiKernel v8r1 and head revision (Flr)
   GaudiKernel/IGiGa*.h - update include file path to new schema.
 
 ! 20000119 Pere Mato
  <<< Changes are not compatible with existing packages. Everything should be re-built >>>>
  - Eliminated static library GaudiBase.
  - Eliminated the constant data files IInterface.cpp and Kernel.cpp
  - Renamed class IID to InterfaceID
  - Added de definition of the InterfaceID (IID) constants in each interface Ixxxx.h file
  - Introduced new file ClassID.h which constains some the definition of CLID and some basic
    constants.
  - Changes asked by Vanya for the classes: ILVolume, IPVolume, ISolid, IGeometryInfo,
    IDetectorElement
 
 ! 20001215 Pere Mato
  - Renamed Time::Time class by TimePoint class
  - The constants Time::time_absolutepast and Time::time_absolutefutre are now defined 
    in the TimePoint.h. The namespace Time has been removed.
    
 ! 20001213 Pere Mato
  - Cleanup and adaptation to the new way of documenting the code based
    on Doxygen (JavaDoc style)
  - Incorparated changes done by D.Quarrie in the old LHCb repository
 
  - Add isInitialized() and seInitialized() member functions and handling to prevent
    multiple initialization attempts on the same Algorithm. This protection is needed
    when scripting is in use.
 
 ! 20001119 - David Quarrie
  - Implemented a new service called ScriptingSvc. This is a service (with an
    initial implementation based on Python), which provides a scripting capability
    at run-time as opposed to the JobOptionsSvc which is limited to run startup
    time. This service has entailed some changes to the Gaudi kernel classes, which
    are mainly extensions to existing interfaces, but with some backwards-compatible
    rework of several of the Property classes.
    + Added new interface: IScriptingSvc
 
 - Auditor/Auditor
   Same changes as for Algorithm.
 
 - Interfaces/IServiceLocator
   Add list<IService*> getServices() for symmetry with the IAlgManager.
 
 - JobOptionsSvc
   A major rework of the Property class hierarchy to better support the scripting
   interface. For the most part the changes are backwards compatible, with the
   exception that bounds checking involves use of a verifier().  Note that the
   PropertyRef.cpp & .h files are obsolete since that class is now typedef'd.
   The PropertyList class for nested properties is not yet functional. Both of
   these classes have been retained but bypassed in the build for now.
 
 - Kernel/Service
   Replace overloaded declareProperty function by function template.
   Add PropertyMgr* accessor
 
 - ApplicationMgr/AppMgrUI
   Add AppMgrUI class as intermediate class between IAppMgrUI and
   ApplicationMgr. This simplifies the scripting interface.
 
 
 ! 20001204 Pere Mato
   Moved in ObjectVector<T> and ObjectList<T> from the LHCbEvent package.
   Removed iterator from ObjectContainerBase class
 
 ! 20001122 Pere Mato
   Various changes needed for CMT v1r7 and Nmake
 
 ! 20001128 GaudiKernel v8
   move *.cpp into src/static/ and src/Lib/
   move *.h, *.icpp and GaudiFactory.cpp into GaudiKernel/
   update #include statements
 
 !=============================================================================
 ! 20001018 - Pere Mato
  - Implemented a new service called IncidentSvc. This allows to communicate 
    asynchronously things that happen in the system. The ApplicationMgr uses it to inform
    when begining and ending the processing of one physics event.
    + Added new interfaces related to the new service: IIncidentSvc.h, IIncidentListener.h
    + Added new base class: Incident.h
 
  - Changed IHistogramSvc to be consistent with the (HTL) histogram implementation using
    double for defining histogram edges instead of float. Code using histograms needs to
    be re-compiled!!. (CT0000000035488)

                   to please CMT v1r5
 
 ! 20000617 - Vanya Belyaev
   - Bug fix in Gaudi/System/System.cpp file in method char** System::argv()
 
 ! 20000616 - Pere Mato
   - Changed Algorithm base class. Added an error counter and max error 
     limit to allow continuation of trhe program. Default is one.
     Added accessor to RndmGenSvc from base class.
 
 ! 20000615 - (Pere Mato, David Quarrie)
   - Changed interface IAlgorithm and base class Algorithm to support 
     Algorithm sequences (Babar style). Added some more algorithm flags
    (enabled, executed, fileter passed, ...) in base class. Added method
     reasetExecuted() in the IAlgorithm interface.
   - Changed IProperty interface to support property browsing. Added the
     following methods:
     const Property& getProperty( const std::string& name ) const = 0;
     const std::vector<Property*>& getProperties( ) const = 0;
   - Changed base class Property to introduce the possibility of asking
     to a property for its type. 
   - Introduced new classes: PropertyList, CommandProperty
     A PropertyList is a Property that contains an array of other properties
     A CommandProperty has a callback function associated that is called 
     when a new value of the property is set.
     The PropertyList can handle property nesting. The name convention is
     that names are separated by ":".  
   - Changed PropertyMgr to base its implementation with PropertyList
 
 ! 20000609 - (Markus Frank)
   - Main improvement:
     Implementation of the public part of the random number generator package.
 
   Besides this I **had** to do some code cleanup:
   - Algorithm.h: Removed Algorithm::create(...) 
     Function was declared but never implemented.
   - IChronoStatSvc.h: "long double" is not really a ansi data type.
     Changed to double.
   - IDataManagerSvc.h
     IID_IDataManagerSvc_NO_ERROR = SUCCESS becomes
     IID_IDataManagerSvc_NO_ERROR = IInterface::SUCCESS
   - ITime.h: use longlong data type from kernel.h instead
     of __int64 and "long long" + #ifdef.
   - PropertyRef.h: Simple typedefs of simple properties.
     e.g. typedef SimplePropertyRef<int> IntegerPropertyRef;
     just as it is done in "Property.h".
   - DataObject.cpp: Actually implement 2 member functions which
     were always in the header, but never made it to code.
   - Kernel.h: If neither Linux nor WIN32 is the platform,
     fix "longlong" to a 64 bit structure capable of holding
     the variable.
   - StreamBuffer.h: Clean up internal classes ContainedLink and 
     IdentifiedLink, get rid of macros
   - Message.h: There is no such class "ostream". Use #include <iostream> instead;
   - MsgStream.h: Added copy constructor
   - NTuple.h:    Get rid of a few macros and write the proper code instead.
   - Get rid of NTupleFile.h and NTupleDirectory.h - should never have 
     been used at all. The classes were always defined in NTuple.h!
 
 
 ! 20000525 
 
 - Fixed template instantiation in Ntuple::Item (For version 6 of Visual C++
 - Corrected "OuputLevel" bug in Service.cpp. This would not take into account
   a change in the OuputLevel for services.
 
 ! 20000523 
 
 Markus Frank Make System.cpp compile under VC 6.0 which opposite to VC 5.0
              defines STRICT by default.
 
 ! 20000410 - Gaudi v6
 
 New EventSelector Interface  06/04/2000 
 ----------------------------------------
 Gonzalo Gracia Abril: IEvtSelector.h modified
 
 Gaudi splited into Gaudi and GaudiSvc
 -------------------------------------
 - Nearly all services moved into the new package GaudiSvc
 - Gaudi remains to contain only interfaces, base classes,
   DataSvc and ConversionSvc
 - Gaudi uses the new package LHCbCMT
   (Pavel Binko)
 
 Small correction in Service.cpp/h
 ---------------------------------
 - Added const function messageService() which was 
   necessary to get a MsgStream in any constant function
   (Gonzalo Gracia Abril)
 
 New Functionality
 -----------------
 - New histogram 1D and 2D interfaces, conforming the AIDA interfaces.
 - HistogramSvc changed - the LHCb histogram implementation uses now
   the HTL implementation of histograms through the AIDA interfaces.
 - HistogramSvc and NTupleSvc changed in order to allow their moving
   to the new package GaudiSvc.
 
 ! 19991116 - Gaudi v5
 
 New Functionality
 -----------------
 - Added a output level threshold associated to the clients (services &
   algotihms) of the MessageSvc overriding the global threshold.
 - New JobOptions service implementation with a new parser.
 - Support for N-tuples.
 - Support for dynamic library loading
 
 Improvemenets
 ------------- 
 - Added interfaces for detector description
 - Improved ParticleProperty service. Added index by LundID.
 - Modified ApplicationManager to acommonatye other changes
 
 ! 19991018 - Gaudi v4r1
 
 New Funtionality
 ----------------
 - Data service and conversion services changed, information about
   storage types and class IDs added
 - HTL histograms supported
   + New HTL interfaces are the Interfaces directory,
     their syntax does not differ from the native HTL syntax
   + Compilation with the HTL library nedds the flag HTL_USE_STD
 
 Changes done by Markus Frank, Pere Mato, Pavel Binko
 
 
 ! 19990812 
 
 New Funtionality
 ----------------
 - Support for dynamic link libraries (shareable libraries):
   + Added interface IClassManager with a method called loadModule()
   + Added interface IFactory as a base interface for all factory interfaces
   + Added a FactoryTable static class to support DLLs
   + Modified implemtation of AlgFactory and SvcFactory to use new interfaces
   + Added new property ("DLLs") in ApplicationMgr to set a list of DLL to be loaded at run time
   + Temporary compilation macro to use Gaudi with DDLs (GAUDI_USE_DLL)
 
 Improvements
 ------------
 - Removed "std" from the names of standard services instances.
 
 ! ========================================================================
 
 ! 19990618 - Gaudi v4
 
 Changes done by Markus Frank, Marco Cattaneo, Paul Maley, Pere Mato
                 Rado Chytracek, Iain Last, Pavel Binko among others
 
 New Functionality
 -----------------
 - Support for Detector Descriptions:
   New classes: DetDataSvc, DetectorElement
   New Interfaces: IgeometryInfo
 - Particle Property service:
   New classes: ParticleProperty, ParticlePropertySvc
   New interfaces: IPartoplePropertySvc
 
 Improvements
 ------------
 - Kernel:
   Added classes: GenericAddress, GenericLink
   Many changes in base classes to support new functionality.
 - Algorithm:
   Changed initialization methods (sysInitialize(), sysFinalize())
   Added assessors to standards services
 - ApplicationMgr:
   Changed to support new services (DetDataSvc, ParticlePropertiesSvc,...)
 - DataSvc:
   Improvements in interfaces. Changed the way to name a DataObject in the store.
   Added classes: SmartDataLocator, SmartDataObjectPtr
 - MessageSvc:
   Added classes GaudiErrorHandler and GaudiNagHandler to
   interface NAG C error handling to Gaudi/MessageSvc. 
   In order to avoid compile time dependency of Gaudi on <nag.h>,
   GaudiNagHandler is defined inline. Applications using this
   facility must #include "Gaudi/MessageSvc/GaudiNagHandler.h".
   Details of usage can be found at:
   http://lhcb.cern.ch/~cattanem/LHCb/GaudiNagC.html
 - PersistencySvc:
   Changed to support two or more conversion services. This was needed to
   support the Root conversion service. 
   Added classes OutputStream, OutputStreamAgent
