    ! 2017-02-08 - Charles Leggett (commit 09859bd)

     - add sysExecute(EventContext) and extract errorCount from Algorithm base class

       We need to extract the `m_errorCount` variable from the Algorithm base class,
        as it's not important on a per-instance basis, but rather on a job level.
       This is moved to the AlgExecStateSvc.
        This merge request also adds an explicit `IAlgorithm::sysExecute(const
       EventContext&)`, which should become the standard entry point to
       `Algorithm::execute`. This sets the local m_event_context variable, so
       derived classes can get quick access to the current context instead of going
       through the slower thead local `Gaudi::Hive::currentContext()`.
        Note that `IAlgorithm::sysExecute()` has been removed, to avoid "overloaded
       virtual" compiler errors, and should be replaced in all clients with
       `IAlgorithm::sysExecute(EventContext)`, or if the context is not immediately
       available, with `IAlgorithm::sysExecute(Gaudi::Hive::currentContext())`.
        All this is being done in preparation to re-introduce the ReEntrantAlgorithm
       class from merge !177 (see also !274)

     - Data object handle demangle name in error

       Small improvement to `DataObjectHandle` to use System::typeinfoName to
       extract the type when issuing a mis-match error message. Results in the type
       being de-mangled from something like

       ``` ERROR The type provided for /Event/Rec/Track/BestRichDown is

       and is different form the one of the object in the store.

     - CMake configuration changes to build Gaudi with optional externals missing

       In the last days I experimented a bit with teaching Gaudi how to build when
       only ROOT, Boost and TBB are available to it. This is the result. As far as I
       can tell the code builds in the same way as the current master branch when
       all possible externals are available. (All the ones available in a full ATLAS
       offline build at least.) And I'm also able to build the project in these
       modes:
         * On Ubuntu 16.04 with the system provided Boost and TBB versions, against
       a privately built ROOT 6 version.
         * On macOS Sierra against privately built Boost, ROOT and TBB versions.
       Both when building the project completely on its own, and when building it
       against an ATLAS externals project.
        Some notes:
         * The code uses C++14 expressions in quite a few places by now. So I raised
       the default C++ standard to C++14. This is the default in ATLAS builds since
       a while, I only saw this as an issue when building Gaudi "on its own" with a
       very minimal configuration command.
         * While the code advertises that it still has support for ROOT 5, it's not
       able to build against it since a wile. Since the updates I put in for TLS
       variables on macOS. (The macros used there are ROOT 6 only.) And this update
       makes things even worse. As the code now relies on not providing the
       definition of some classes to the dictionary generator in GaudiPython that
       are not available. (Because AIDA or XercesC is missing.) While ROOT 6 handles
       this with just a build warning, ROOT 5's genreflex treats this with an ERROR
       message. That I was unable to get rid of.
        So, extended testing is clearly necessary, the configuration code could
       definitely be fine tuned as I probably turned off the build of more source
       files than absolutely necessary, but I think we should move ahead with such a
       configuration organisation.

     - Allow ADL lookup of parse and toStream

       Currently, if one introduces a `Gaudi::Property<T>`, then there must be a
       corresponding `StatusCode Gaudi::Parsers::parse(T&,const std::string&)` in
       the namespace `Gaudi::Parsers` and a corresponding `void
       Gaudi::Utils::toStream(const T&, std::stream&)` in the namespace
       `Gaudi::Utils`.
        This patch explicitly enables
       [ADL](http://en.cppreference.com/w/cpp/language/adl) lookup (with a fall-back
       to `Gaudi::Parser::parse` and `Gaudi::Utils::toStream`) so that it is
       sufficient to either define `parse` and `toStream` in the namespace in which
       `T` is defined, or add them as `friend` functions to `T`.

     - Add accessor to ServiceHandle to allow non const access to service, even from

       See the discussion in gaudi/Gaudi!225
        I am not completely sure what I think of this. I am not completely sold on
       the idea, but can see Services are different beasts to tools.
        I submit this for discussion and testing by Atlas( @leggett I've tested it
       in as far as Gaudi compiles but as in LHCb we have no use case that requires
       it, cannot go much future. It would be good if this MR could be tested
       against Atlas *before* merging this time ;))

     - More efficient Toolhandle<T>::get() method

       I would like to use ToolHandle more, but I also want to use it optimally
       efficiently, by which I mean I want inline access to the underlying tool
       pointer, with no validity checks (I always `retrieve()` my tools up front in
       initialize()) and true const behaviour (for thread safety). Essentially what
       I want is `GaudiHandle<T>::get()`, but unfortunately in the current
       implementation this method is hidden behind the virtual
       `ToolHandle<T>::get()` method, that also down casts the tool to `IAlgTool*`
       (so no use for direct usage).
        This MR fixes both these issues. get() is now fully optimal in
       `ToolHandle<T>` as it simply refers back to GaudiHandle in an inline method.
        The `BaseToolHandle<T>::get()` method is just a wrapper that calls a hidden
       (protected) virtual function (`getAsIAlgTool()`) that returns what get()
       previously did.
        I also tightened up the const'ness, providing both const and non-const
       methods that return const and non-const tool pointers respectively.
        I also updated a few methods to remove multiple return statements (which
       normally cause compilers to abort inlining) and adding some `noexcept` here
       and there..
        The only API change is that `ToolHandle<T>::get()` now returns `T*` instead
       of `IAlgTool*`, but this is not a problem as the user can still choose to use
       it as a `IAlgTool*` if they want..
        Gaudi master builds fine with this, not tested any other projects yet.
        cheers Chris

     - modernization of Property

       This is a major rewrite of the system of `Property` classes. Started as  the
       implementation of GAUDI-1214, it continued as a review of
       `IProperty` and `PropertyMgr`, to end up in a complete rewrite
       (and optimization) of `PropertyWithValue`.

       * Fixes GAUDI-1214
        - added missing `declareProperty` signature
        - added `PropertyHolder` (an updated `PropertyMgr`)
        - adapted all properties in Gaudi
       * improved use of `PropertyHolder`
        - use inheritance instead of composition
        - removed ~200 (duplicated) lines of code in GaudiKernel
       * optimization of Property (fixes GAUDI-1229)
        - use templates and automatic code generation to handle efficiently
          both value and reference properties
          - avoid creation of values on the heap (see GAUDI-1229)
          - removed the *owned* boolean flag
          - improved usability of properties (e.g. begin/end wrappers for
            C++11 loops, increment/decrement operators...)
          - deprecated use of C arrays as properties
        - merged features of `PropertyWithVerifier`, `SimpleProperty` and
          `SimplePropertyRef` into `PropertyWithValue`
        - deduplication of name and doc strings via

       [`boost::string_ref`](http://www.boost.org/doc/libs/1_61_0/libs/utility/doc/html/string_ref.html)

          and a static storage  (see GAUDI-1229)
       * Fixes GAUDI-1205
       * add deprecation warnings in service accessors of `Algorithm` (@graven)
       * renamed `Property` base class to `Gaudi::Details::PropertyBase` and
       `PropertyWithValue` to `Gaudi::Property`
        - added backward compatibility type aliases (but not compatible with
          forward declarations of `class Property`, which should be replaced
          by `#include "GaudiKernel/PropertyFwd.h"`)
       * added macro `GAUDI_PROPERTY_v2` to allow easy implementation of
        backward compatible changes in derived projects (e.g. when user code
        relied on `DoubleProperty` having a verifier)
       * Fixes GAUDI-1268
        The changes are as backward compatible as much as possible (except if you
       explicitly inherit from `SimpleProperty`, or you forward declared
       `class Property`, which now are typedefs), but must be validated in the
       experiment frameworks.

     - Algorithm Execution State Service

       Introduction of AlgExecStateSvc
        All event state information removed from Algorithm base class
       (m_filterPassed, m_isExecuted) as it will cause difficulties with re-entrant
       Algorithms.
        event success/fail flag removed from EventContext
        These flags are moved to be under control of a new service, the
       AlgExecStateSvc, which keeps track of the execution state of all Algorithms,
       and the Event as a whole.
        Algorithm status kept in a new class ```AlgExecState``` which has
       ```
           bool m_filterPassed  {true};
           bool m_isExecuted    {false};
           StatusCode m_execStatus  {StatusCode::FAILURE};
       ```
        AlgExecStateSvc holds an AlgExecState for each Algorithm in each Event
       Slot, as well as an overall ```EventStatus``` for each EventSlot, which can
       be one of

       ```
         Invalid = 0,
         Success = 1,
         AlgFail = 2,
         AlgStall = 3,
         Other = 4
       ```
        Algorithms add themselves to the AlgExecStateSvc upon initialization, but
       the Service's initialization of  the data structures is deferred until the
       first time ```AlgExecStateSvc::reset()``` is called, at which point it's
       probably safe to figure out if there's a WhiteBoard, and the number of slots
       to allocate.
        The EventLoopMgr should call ```AlgExecStateSvc::reset()``` at the start of
       each event. If it's a concurrent EventLoopMgr, it should be
       ```AlgExecStateSvc::reset(EventContext)```, after the EventContext object
       has been updated to reflect the new event.
        Also added an EventContext object to the MinimalEventLoopMgr, so that
       serial/concurrent behaviour is similar.
        Concurrent queries to the AlgExecStateSvc must contain the EventContext, so
       the correct EventSlot can be determined. Serial access is via methods that
       don't have the EventContext as a parameter. For access from Algorithm base
       class (eg from setFilterPassed, isExecuted, etc), if the EventContext ptr
       (m_event_context) in the Algorithm is null, we assume we're running
       serially.

     - Thread tool termination

       This set of changes completes the work started by @leggett in
       a875c69e3ac6b1d1253e4086daea076860a95e52 on thread initialization tools. Such
       tools are invoked by the ThreadPoolSvc on each worker thread when the pool is
       initialized and can be used to setup thread-local workspaces in cases where
       necessary (e.g. for running multi-threaded Geant4).
        These commits enable the thread-termination part of those tools for
       corresponding cleanup/finalization of thread-local memory. This is done
       primarily by adding a terminatePool method to IThreadPoolSvc which is called
       at the end of ForwardSchedulerSvc::activate. The ThreadPoolSvc underwent some
       slight refactoring to support the thread-termination tasks.
        Also included in this merge request are a number of whitespace and
       indentation fixes, as well as some added class documentation in the affected
       classes.

     - Isolate EventContext from Algorithm

       in order to not have re-entrant Algorithms stomp on each others'
       EventContexts, we need to isolate the EventContext from the Algorithm, and
       move it to the AlgoExecutionTask. We can then pass the EventContext
       explicitly to the tbb::task, instead of carrying it via the Algorithm, which
       would fail for re-entrant Algs. This also requires a change to the signature
       of ForwardSchedulerSvc::promoteToExecuted.
        We should also make the EventContext* of the Algorithm const, to prevent any
       modification from inside the Alg.

    ! 2016-03-10 - commit f84ad02

     - Register Tools declared in ToolHandleArray in parent Algorithm/AlgTool

       data deps of Tools in ToolHandleArrays are not pushed to parent Alg/AlgTool
        need to add a declareProperty(... ToolHandleArray<T> ...) to Algorithm and
       AlgTool, and add all ToolHandleArrays thus declared to a container that gets
       processed during initToolHandles. In order to avoid adding tools from Arrays
       that haven't been retrieved, we have to add a bool flag to the
       GaudiHandleArrayBase to detect if it's been retrieved. there's a bit of
       ugliness in extracting a ptr to an IAlgTool from the untemplated
       GaudiHandleArrayBase, as we have to explicitly retrieve the tool from the
       ToolSvc by name, but since it's already been retrieved when the Array gets
       retrieved, we won't be doing any new creations.
        I believe that the testing for whether the retrieved tool is public or
       private is redundant, as I don't think you can put a Public tool into a
       Private ToolHandleArray (at least you can't seem to do so in ATLAS), but I
       left it in just in case.

     - use StringKey for Alg name, add IAlgorithm::setIndex

       this patch does 3 things:

       - makes Algorithm::index() const (as it should have been), set the initial
       value to 0 instead of 123 (!)
       - adds a protected Algorithm::setIndex(unsigned int) method. this allows you
       to distinguish between clones. AlgResourcePool is the one who does the
       setting, and is declared as a friend to IAlgorithm
       - turns Algorithm::m_name into a StringKey (from a string), so we can hash on
       the name of Algorithms more easily (a useful ability when dealing with Alg
       clones, and trying to treat them all the same way)

     - Merge branch 'GAUDI-1183' into 'master'

       reorganize DataHandleHolder visitor acces to avoid non-retrieved tools
        This is not a perfect fix, more a workaround.
        The method `initToolHandles` have been modified to fill the list of used
       `ToolHandle`s only with the tools retrieved explicitly in the `initialize`
       method.

       `GaudiCommon` required the introduction of a hook so that the custom _fixer_
       visitor could be created in the `GaudiCommon::initialize`, but used only at
       the end of `PBASE::sysInitialize` (eb39274).

     - return the just-added tool from addTool

       augment addTool to return the tool it just added.
     This allows one to write:
       ```python
     myToolWithName = myalg.addTool(tool_conf2,"ToolWithName")

       myToolWithName.String = "xyz"
       ```
     instead of
       ```python
     myalg.addTool(tool_conf2,"ToolWithName")

       myalg.ToolWithName.String = "xyz"
       ```
     which requires one to duplicate the "ToolWithName" -- once as string,
       and
     once as attribute, but only rarely does anybody use getattr for the 2nd

       case to just avoid the duplication.
        Of course, one could write
       ```python
     myalg.addTool(tool_conf2,"ToolWithName", String="xyz")
       ```
     or even pass in a complete dictionary with **, but the configuration of

       the tool isn't necessarily complete at the time of creation of its

       configurable.

     - change return type of Property::declare{Read,Update}Handler from void to
       Property&,

       The reason is that this way one can write code like this:
       ```C++
        declareProperty("trackMaxChi2", m_trackMaxChi2 = 25.)
          ->declareUpdateHandler( [this](Property&){ this->m_trackChi =
       std::sqrt(this->m_trackMaxChi2); } )
          .useUpdateHandler();
       ```
     this keeps m_trackChi in sync with m_trackMaxChi2. Without the call
     to
       useUpdateHandler, if there is no entry in the JobOptionsSvc,
     m_trackChi
       would not be set, and one would have to duplicate the
     code to 'derive'
       m_trackChi from m_trackMaxChi2 just to initialize
     it to the proper default.

     - Allow compilation of Gaudi with clang 3.7 using gcc 4.9 externals

       To do so, some arguments have to be passed to cmake, assuming CMTCONFIG is
       x86_64-slc6-clang37-opt
        * LCG_SYSTEM: To specify the flavour of the externals to use
        * LCG_FORCE_COMPILER: To specify the compiler to use, with the
          format "<compiler>-<version>" (an lcg wrapper has to exist for
          this to work).

       Using the LHCb Makefiles, you just need to specify:
       ``` export CMAKEFLAGS="-DLCG_SYSTEM=x86_64-slc6-gcc49
       -DCMAKE_EXPORT_COMPILE_COMMANDS=1 -DLCG_FORCE_COMPILER=clang-3.7"

     - Merge branch 'dev-stateful' into 'master'

            restart and FSMState which, presumable not by coincidence, also happens
       to be the functions which IStateful declares.

     - Merge branch 'dev-smartif-use' into 'master'

       Provide (and use) C++11 smart pointer 'look and feel' for SmartIF

       The aim of this branch is to confine, for everything that inherits from
       IInterface, the calls to addRef(), release() and queryInterface() to the
       SmartIF implementation. Exceptions are a few places where interfaces
       (currently) return bare pointers (instead of SmartIF...) and where one thus
       has to addRef() explicitly to avoid returning a dangling pointer. This can be
       avoided by changing the relevant interface to return a SmartIF instead of a
       bare pointer.

       In addition, make SmartIF 'look and feel' like a smart pointer.

       - use explict bool conversion instead of .isValid()
       - add SmartIF::as<IFace>(), to return a SmartIF<IFace> to an alternate
          interface -- which (together with move) encourages the use of auto
       - add ISvcLocator::as<IFace>(), to return a SmartIF<IFace> to the current
       ISvcLocator.
       - add ServiceManager::service<IFace>() which return SmartIF<IFace> which
       encourages
          the use of auto

       And add a few other C++11 modernizations (eg. prefer STL over raw loop)

     - Merge branch 'AppMgrUI' into 'master'

       Switch IAppMgrUI inheritance from Interface to INamedInterface and remove the
       pure virtual name()

       IAppMgrUI inherits from IInterface, and adds a pure virtual name() method
       with the exact same signature as the one in INamedInterface.

       As a result, the same effect can be obtained by inheritance from
       INamedIterface instead of IInterface.  The advantage is that if an
       implementation (virtually) inherits not only from IAppMgrUI but also another
       interface which (virtually) inherits from INamedInterface, there is no
       ambiguity in the definition of name(). With the 'old' code, one has to
       disambiguate between multiple name() members...

    ! 2015-09-17 - commit d53e750

     - Merge branch 'dev-common-messaging' into 'master'

       Generalize CommonMessaging, and use it to implement the messaging
       functionality ...

       ...in GaudiAlg/GaudiCommon

         CommonMessaging needs two methods to be available to implement its
       functionality:

               const std::string& name() const
              SmartIF<ServiceLocator>& serviceLocator() const

         As CommonMessaging is a mix-in class which uses the 'curiously recurring
       template'
        pattern, it can either demand that the 'Base' class it is 'mixed' into
       already
        provided this functionality, or it can add pure virtual methods to insure
       any
        derived class does so. As this depends on the template argument, one cannot
        a-priori decide which of the two solution is appropriate.

         To solve this problem in a generic way, this patch uses SFINAE to detect
        at compile time whether Base::name() and Base::serviceLocator() -- where
        Base is the template argument provided to CommonMessaging -- are valid
        expressions. If they are, no further action is taken. If not, the missing
        function(s) is (are) added as pure virtual. This is done by specialization
        of two template classes from which CommonMessaging inherits, prior to
        inheriting from Base.  Those specializations are either 'empty' classes,
        or add the missing interface requirement.

         files and _merged.confdb files (if the merged one is present, ignore the
         others).
       - Minor code clean up in loadConfigurableDb.
       - Added tests for loadConfigurableDb (CMake only).

    ! 2014-05-06 - Sebastien Binet
     - fix bug #102404: implement a pure ascii based configurable-db.

       ContextSpecificPtr.

    ! 2013-10-28 - Marco Clemencic
     - Added unit test for Gaudi::Hive::ContextSpecificPtr.

    ! 2013-10-27 - Marco Clemencic
     - Added Gaudi::Hive::ContextSpecificPtr, a smart pointer with independent
       values for different tasks.
       In addition to the standard smart pointer functionalities, it features:
         - ``accumulate`` to allow gathering of informations collected in different
                          contexts (slots)
         - ``for_each`` to call a function on each pointer
         - ``deleteAll`` to delete all the created objects

     - Keep the buggy implementation of 'applyConfigurableUsers()' (bug #103803) to
       provide backward compatibility until all the problems with the configuration
       are fixed.

    ! 2014-02-07 - Marco Clemencic
     - Fixed bug #103808: regression introduced with the fix to bug #103803

    ! 2012-10-21 - Marco Clemencic
     - Added implementation of a serial task queue: Gaudi::SerialTaskQueue (based on
       the TBB Pattern 'Local Serializer').
       Users of SerialTaskQueue must implement the tasks to be executed as
       specializations of the class Gaudi::SerialTaskQueue::WorkItem, overriding the
       member function 'run()'.
       Tasks are enqueued with the method 'add(WorkItem*)' of SerialTaskQueue.
       The destructor ensures that all the tasks are completed before giving back
       control.

     - Fixed compilation warnings.

    ! 2012-09-10 - Benedikt Hegner
     - Added missing copy constructor and assignment operator to 'implementsN<>'
       base class.
       They should not be needed because components cannot not really be copied or
       cloned, but in some cases there are copy constructors and assignment
       operators defined in the derived classes and in those cases the reference
       count should be set to 0 in the initialization of a new object and not
       touched by an assignment.

       It is needed to be able to run the tests from the build directory (CMake).
     - Modified the test for bug #87340 to work without the installation of
       libGaudiKernel.so (CMake).

     - Hidden compilation warnings in Grammars.h using the pragma "system_header".

    ! 2011-07-26 - Marco Clemencic
     - Improved the stability of HistoryObj and IVersHistoryObj in dynamic_cast.

    ! 2011-07-26 - Markus Frank
     - Patch #4999: Added virtual destructor implementation for IUpdateableIF

    ! 2011-07-25 - Marco Clemencic
     - Fixed a compilation problem triggered by the changes in some header files.

    ! 2011-07-22 - Marco Clemencic
     - Divided the bulk of parsers in several small files to speed up the
       (parallel) compilation.

    ! 2011-07-22 - Sasha Mazurov
     - Patch #4891: New parsers for Gaudi Configuration
       - Fully rewritten parsers (less amount of code, more readable and more robust)
       - Based on Boost.Spirit 2
       - New parsers for std::set and std::list
       - Job options files: variables introduced

    ! 2011-07-21 - Charles Leggett

       Update HistorySvc to use new HistoryObj base classes, and provide XML output

    ! 2011-07-21 - Marco Clemencic
     - Added use of 'UNLIKELY' in the destructor of StatusCode.

    ! 2011-07-21 - Charles Leggett
     - Patch #4975: check for uncaught exceptions in StatusCode destructor
       If a StatusCode is created in some alg, and an exception is thrown before
       it's checked, when the stack is unwound it will trigger an unchecked status
       code error from the StatusCodeSvc, which can mislead people as to the true
       cause of the problem.
       This patch checks for std::uncaught_exception() in the StatusCode destructor
       before calling the StatusCodeSvc.

    ! 2011-06-27 - Marco Clemencic
     - Fixed a problem with the compilation of genconf on ICC after the fix to
       bug #83433.

     - Fixed a defect spotted by Coverity in KeyedObject (UNINIT_CTOR).

    ! 2011-04-18 - Marco Clemencic
     - Moved the LIKELY and UNLIKELY macros to GaudiKernel/Kernel.h

    ! 2011-04-15 - Charles Leggett
     - added LIKELY and UNLIKELY macros to improve branch prediction for linux
     A       GaudiKernel/likely.h

    ! 2011-04-15 - Marco Clemencic
     - Fixed a warning triggered by the macro NDEBUG.
     - Fixes to patch #4820.

       Fix bug accessing system-memory information, if process memory is > 4GB.

    ! 2011-04-08 - Marco Clemencic
     - Introduced two new incidents: BeginProcessing and EndProcessing.
       They are needed to reintroduce the signals around the processing loop as
       it was the case for BeginEvent and EndEvent before GaudiSvc v17r0.

    ! 2011-03-28 - Marco Clemencic
     - Fixed a typo.

    ! 2011-03-23 - Marco Clemencic
     - Fixed VC9 warnings.
       - Replaced C-style string manipulation and formatting with C++ (and Boost)
         implementations.
       - Disabled some warnings.
       - Removed some "empty" files (files producing empty objects files),
         replacing them with a test .cpp file to ensure that the headers do not
         contain syntax errors.

    ! 2011-03-22 - Marco Clemencic
     - Added a function to convert IAuditor::StandardEventType to const char*,
       (toStr) needed to simplify the implementation of some auditors.

    ! 2011-03-17 - Marco Clemencic
     - Modified DirSearchPath to remove boost::filesystem::no_check. It is not
       needed and breaks on MacOSX in debug mode (at least with Boost 1.44).
       See patch #4735.
     - Fixed PathResolver_test to work on MacOSX.

    ! 2011-03-16 - Charles Leggett, Marco Clemencic

    ============================= GaudiKernel v27r12 =============================
    ! 2011-01-19 - Markus Frank
     - Fixes for bug #77109.
       Add a virtual "update()" method to the DataObject.
       This method should then be called unconditionally by converters.
       Remove the obsolete "serialize()" methods.
       Apply this method to the keyed containers and replace the
       existing "configureDirectAccess()" method with "update()".
       (patch #4613)

    ! 2011-01-14 - Markus Frank
     - Patch #4607: Do not store process id.
       ProcessDescriptor.cpp Do not locally store the process id (pid).
       This causes problems e.g. after a call to fork(), because the data
       accessed are those of the parent process, not the newly created process.

    ! 2011-01-11 - Marco Clemencic
     - Fixed some ICC remarks.

    ! 2011-01-07 - Marco Cattaneo
     - Locally disable few ICC remarks.

         (GaudiKernel/AppReturnCode.h)
       - Set appropriate return code in case of "scheduled stop" and unhandled exceptions
         (MinimalEventLoopMgr)

    ! 2010-09-17 - Vanya Belyaev
     - Fixed bug #72170: Python Parsers and map of <string, unsigned int>
       Added support for map<string,unsigned int>.

     - Minor fix to make_patch.py

    ! 2010-09-14 - Marco Clemencic
     - Fixed a warning introduced with patch #4394.

    ! 2010-09-13 - Charles Leggett
     - Patch #4394: rewriting PathResolver using boost::filesystem
       - simplified the code
       - small change in behavior:
         if the search for "B/a.txt" is not successful, the original PathResolver
         would traverse the search list again looking for just "a.txt"; not it is
         not the case anymore

    ! 2010-08-23 - Marco Clemencic
     - Modified "loadConfigurableDb" to be able to find *_merged_confDb.py in any
       subdirectory of the InstallArea (needed to be able to install platform-
       independent files in the platform-specific directories, see GaudiPolicy).

    ! 2010-08-20 - Marco Clemencic
     - Modified src/Lib/Debugger.cpp to compile on VC9.

    ! 2010-08-19 - Marco Clemencic

       the maps and make them behave as Python dictionaries.

    ! 2010-05-11 - Marco Clemencic
     - Fixed bug #64571: Python 2.6 warnings
       Removed extra arguments in the call to "object.__new__".

    ============================= GaudiKernel v27r9 ==============================
    ! 2010-04-22 - Marco Clemencic
     - Use the property "ReturnCode" of the ApplicationMgr as return value of the
       application (Gaudi.exe).
     - Added a couple of helper functions to easily set/get the return code of the
       application (GaudiKernel/AppReturnCode.h).

    ! 2010-04-20 - Marco Clemencic
     - Removed ICC warnings and remarks.

    ! 2010-04-16 - Vanya Belyaev
     - Patch #3943: Good names for StatEntity methods
       - GaudiKernel/StatEntity.h: add new names for "ugly methods"
             flag        -> sum
             flagMean    -> mean
             flagMeanErr -> meanErr
             flagRMS     -> rms
                 ...
         All "flag" methods are moved into "legacy"-section.
         The old methods were OK when Counter has two fields "flag"(additive) and
         "weight" (multiplicative), but after removal of "weight" all these flag*
         methods are ugly.
     - Patch #3989: Tiny (but very important) fix for Gaudi::RangeBase_
       The patch removes the protected destructor form Gaudi::RangeBase_.

    ============================= GaudiKernel v27r8 ==============================
    ! 2010-03-16 -Charles Leggett
     - Patch #3718: Unchecked StatusCode in GaudiKernel/Algorithm.cpp
       Modified the code to avoid Unchecked StatusCode in case of failures.

     - Patch #3912: Add a IInterface-based version of IUpdateable.

    ! 2010-03-08 - Charles Leggett
     - Fixed bug #63502: GaudiKernel/Converter.cpp don't assume converter
       is a ConverterSvc when retrieving name

    ! 2010-03-02 - Marco Clemencic
      - Improvements in ConfigurableUser:
        - Allow dependency between named ConfigurableUser instances.
          The entry in __used_configurables__ can be a tuple where the first element
          is the class (or class name) and the second element is the instance name.
          If the instance name is equivalent to False (None, "", etc.), the name of
          the instance is obtained through the method self._instanceName() that, by
          default, returns "<userclass>_<class>", but can be overridden.
        - Added a method to get a used instance by name: self.getUsedInstance().
      - Minor fix in Configurable: allow to instantiate it passing the name as a
        keyword argument (it was failing if the instance already existed).
      - Fixed a race condition in WatchdogThread.

    ! 2010-02-26 - Marco Clemencic
     - Added a simple generic class (WatchdogThread) for implementation of software
       watchdogs (in the sense of a secondary thread that periodically checks that
       an event has occurred).
       A derived class should implement (at least) the method "action()", which is
       invoked when the time-out occurs without that another thread called the
       "ping()" method of the watchdog.

    ! 2010-01-29 - Marco Clemencic
     - Fixed icc remark #1599: declaration hides variable
     - Fixed icc warning #858: type qualifier on return type is meaningless
     - Fixed icc warning #279: controlling expression is constant

    ! 2010-01-28 - Marco Clemencic
     - Fixed icc remark #424: extra ";" ignored
     - Fixed icc remark #111: statement is unreachable
     - Fixed icc remark #193: zero used for undefined preprocessing identifier
     - Fixed icc remark #522: function "X" redeclared "inline" after being called
     - Fixed icc remark #304: access control not specified ("private" by default)
     - Fixed icc remark #177: X declared but never referenced
     - Fixed icc remark #193: zero used for undefined preprocessing identifier X

    ============================= GaudiKernel v27r7 ==============================
    ! 2010-01-19 - Markus Frank
     - Fixed EventSelectorDataStream to fit with the changes in GaudiSvc
       (support of 'SVC=' in EventCollectionSvc) and removed references to SICB.

    ! 2010-01-15 - Marco Clemencic
     - Fixed compilation on icc 11.
       - cmt/requirements:
         removed the cppflag -Wno-unused-parameter because not understood by icc
         (only for icc).
       - GaudiKernel/HashMap.h:
         modified to use the same code as gcc < 4.3 (ext/hash_map)
       - GaudiKernel/SmartDataPtr.h:
         disabled (icc only) a trick to avoid problems with hidden operator=,
         otherwise icc gives the error
           internal error: assertion failed: add_symbol_to_overload_list
       - src/Lib/Bootstrap.cpp:
         removed the method <anonymous>::ShadowEntry::operator=, never used and not
         accessible outside the translation unit, to avoid a warning.
       - src/Lib/System.cpp:
         removed the declaration "extern char **environ;" from within the method
         System::getEnv() (if on linux), because not needed and icc was trying to
         resolve it as System::environ.
       - scripts/make_patch.py:
         updated the default exclusion list.

    ! 2010-01-15 - Marco Clemencic
     - Fixed a bug in genconf: the third argument passed to the factory of tools was
       IService* instead of IInterface* (it works as long as the memory address is
       the same).

    ! 2010-01-11 - Vanya Belyaev
     - Patch #3478: Registration for Algorithm Context Service
       Moved the registration for the context service from GaudiAlgorithm to Algorithm

     - Fixed bug #59450: valgrind reports conditional or jump depends upon
                         uninitialized variable in ProcessDescriptor
       Fixed following the suggestion in the bug report.

    ============================= GaudiKernel v27r6 ==============================

     - Patch #3357: Comparison of floating point numbers
       GaudiKernel/Lomont.h, src/Lib/Lomont.cpp
         *  The equality comparison of double numbers using as the metric the maximal
         *  number of Units in the Last Place (ULP).
         *  It is a slightly modified version of very efficient implementation
         *  of the initial Bruce Dawson's algorithm by Chris Lomont.
       The functions are copied from Kernel/LHCbMath package

    ! 2009-11-09 - Marco Clemencic

     - Modified genconfuser.py to also print a stack trace in case of ImportError.

    ================ GaudiKernel v27r5 ====================================
    ! 2009-10-19 - Marco Clemencic
     - Improved error reporting in genconfuser.py in case of missing modules and
       always fail on ImportError.
     - Fixed a problem in genconfuser.py occurring when a ConfigurableUser was found
       in more than one python module of the package. Not it is reported as existing
       only in the first imported module.

    ! 2009-10-15 - Marco Clemencic
     - Minor change to ConfigurableUser to allow the declaration of
       __used_configurables__ with strings.
     - Fixed a compilation (visibility) problem on gcc43 with GAUDI_V21 tag enabled
       introduced by patch #2978.

    ! 2009-10-13 - Marco Clemencic
     - Fixed compilation problem on Windows caused by patch #3223.
     - Modified DirSearchPath_test to avoid "/tmp" to make it more Windows friendly.
     - Disabled the support for LorentzVector as Property (patch #3223) on Windows
       (compilation problem).

    ! 2009-10-12 - Marco Clemencic
     - Normalization of white-spaces in Python files.
       (using http://svn.python.org/projects/python/tags/r254/Tools/scripts/reindent.py)

    ! 2009-10-12 - Vanya Belyaev
     - Patch #2978: GaudiKernel/StringKey.h
       New class Gaudi::StringKey to be used as "Efficient" key.
       Essentially it is just a string with pre-computed hash.

    ! 2009-10-08 - Vanya Belyaev
     - Patch #3223: Add some more "Extended" property types to Gaudi

       "Vectors"
            Gaudi::Point3D
            Gaudi::Vector3D
            Gaudi::LorentzVector

        "SVector"
            ROOT::Math::SVector

        "BoostArrays"
            boost::arrays

        "CArray"
            C-arrays

        These properties are not available "on-default"  (why?)
        To use these properties one needs to include the corresponding files
           GaudiKernel/VectorsAsProperty.h
           GaudiKernel/SVectorAsProperty.h
           GaudiKernel/BoostArrayAsProperty.h
           GaudiKernel/CArrayAsProperty.h

        The usage is new proeprties is fairly trivial and illsutrated by
        new exampeles in GaudiExamples package:
           ExtenderProperties2,
           ArrayProperties
           BoostArrayProperties

        Attention:
          For *NOW* one needs to include these files before direct or
          indirect inclusion of  GaudiKernel/Property.h.
          The problem comes from some invalid design of "generic"
          function in GaudiKernel/ToStream.h  (mia culpa).
          I am goind to provide the redesigned version of ToStream.h,
          but it will take some time.
          For a time being one needs to take crea botu the
          inclusion of new headers

    ! 2009-10-07 - Marco Clemencic
     - Patch #3239: Moved Parsers.icpp to the public headers directory (GaudiKernel)

     - Reverted the changes in GaudiException while looking for a better
       solution (too many classes where relying on the internals of
       GaudiException).
       The other changes have been kept.

    ! 2009-09-25 - Marco Clemencic
     - Slightly modified GaudiException, MsgStream end few others to reduce the
       possibility of an exception in the middle of a catch block in case of
       std::bad_alloc (which would result in an immediate exit/abort).

    ! 2009-09-24 - Rob Lambert

     - Patch #3222: Patch to Issue incidents for Input Files
       - Details required for the documentation of output
         files in the Summary services
       - Added method to EventSelectorDataStream
         dbName, returns m_dbName, which contains the parsed dataset name
         required for the issuing of an incident
       - Added extra incident definitions to Incident.h

    ================ GaudiKernel v27r4 ====================================
    ! 2009-08-01 - Rob Lambert
     - Patch #3174: Added ICounterSummarySvc.
       This is a pure abstract interface to allow the persistance of
       counters in a file. This will be implimented by LHCb in the
       writing of an XMLSummary. StatEntities and Stat objects can be added.

    ! 2009-07-31 - Marco Clemencic
     - Modified genconfuser.py to find the local configurables also when the file
       python.zip does not contain them yet.

    ! 2009-07-30 - Marco Clemencic
     - Fixed some doxygen warnings.
     - Use of the tag "no-hide-warnings" to re-enable warnings due to external
       libraries.
     - Added a generic hash function in GaudiKernel/Hash.h (not used by default) to
       allow simpler transition to the new Hash class introduced with patch #2979.

    ! 2009-07-29 - Marco Clemencic
     - Modified the script genconfuser.py to accept an extra option to locate the
       locker module.
     - The scripts merge_files.py, ZipPythonDir.py and genconfuser.py can now be
       synchronized with a "global lock file" defined with the environment variable
       GAUDI_BUILD_LOCK (needed when using tbroadcast or equivalent).

    ! 2009-07-27 - Vanya Belyaev
     - Patch #2979: Modified version of file GaudiKernel/Hash.h
       - _WIN32 specific part (due to non-adequate stdext::hash_map) is removed,
          since stdext::hash_map is not used anymore - GaudiUtils::HahsMap for
          _WIN32 platform is using std::map instead
       - The generic a'la Stroustrup implementation is removed (may break existing
         code)
       - For generic implementation relies on availability of hash_value function in
         a spirit of boost. Boost provides the specializations for the basic
         fundamental types as well for the standard containers
       - there is no specialization for "void*"

    ! 2009-07-22 - Marco Clemencic
     - Modified genconfuser.py to explicitly avoid errors if the imported file tries
       to imports configurables that do not exist.
     - Removed the obsolete merge_genconfDb.py.

    ! 2009-07-20 - Marco Clemencic
     - Fixed a compilation warning in PropertyMgr.cpp.
     - Added '-no_static' to the declaration of the libraries (implemented since CMT
       v1r20p20081118).

    ! 2009-07-16 - Marco Clemencic
     - Support for zipped python directories.
       Modified loadConfigurableDb() to be able to locate the "*_merged_confDb.py"
       inside the .zip files too.

    ================ GaudiKernel v27r3 ====================================
    ! 2009-07-08 - Marco Clemencic
     - Removed the need for extend_interfaces1. Then necessary typedef is added by
       the macro DeclareInterfaceID, simplifying a lot the changes. The drawback is
       that when an interface extends more than one other interface, it must use
       DeclareInterfaceIDMultiBase instead of DeclareInterfaceID.
     - Removed the usage of extend_interfaces1.

    ================ GaudiKernel v27r2 ====================================
    ! 2009-06-29 - Marco Clemencic
     - Removed the special compile time flag for the dictionary (problem fixed in
       ROOT 5.22.00c)

    ! 2009-06-26 - Vanya Belyaev
     - Patch #3019: std::map<std::string,std::pair<double,double> > as property
       Useful for representation of ranges or value+/-error.

    ! 2009-06-26 - Gerhard Raven
     - Patch from bug #52359: Allow setting of logging stream in ProcessJobOptions
       A custom output stream can now be passed to
       GaudiKernel.ProcessJobOptions.InstallRootLoggingHandler().

    ! 2009-06-23 - Marco Clemencic, Vanya Belyaev
     - Patch #2980: Moved Range.h and NamedRange.h from GaudiUtils to GaudiKernel.

    ! 2009-06-22 - Marco Clemencic
     - Disable the macros for the visibility of symbols on Windows, because it is
       impossible (currently) to make coexists the gcc and VC ways.
     - Added a compile time flag for the dictionary to hide warnings.
     - Fixed some compilation problems on Win32.

    ! 2009-06-15 - Hubert Degaudenzi
     - use the new LCG tag convention.

    ! 2009-05-29 - Marco Cattaneo
     - Added "define NOMINMAX" in boost_allocator.h to avoid compilation problems on
       Windows.

    ! 2009-05-25 - Marco Clemencic
     - Fixed bug #45517: Units not taken into account in .opts files
       Added the function importUnits() to populate from python the units used in a
       .opts file.

    ! 2009-05-20 - Yushu Yao
     - Patch #2975: ServiceHandleArray
       Added ServiceHandleArray, similar to ToolHandleArray, but for services.

    ================ GaudiKernel v27r1 ====================================
    ! 2009-05-15 - Marco Clemencic
     - Fixed bug #50389: AppMgr.algorithm/tool/algorithms does not work for
                         GaudiPython::PyAlg<TYPE>
       Changed the inheritance from "implements#": replaced "virtual public" with
       "public" (more correct and does not confuse PyROOT).

    ! 2009-05-14 - Marco Clemencic
     - Fixed an extra "release" of EventDataSvc in EventSelectorDataStream.
       At each new file, the reference count was artificially decreased by 1,
       causing a segmentation fault during finalization.

    ! 2009-05-13 - Eric Van Herwijnen
     - Patch #2998: Extension of IMonitorSvc for StatEntity
       Added a declareInfo method for StatEntity instances.

    ! 2009-05-07 - Marco Clemencic
     - Added backward compatibility hack in SmartIF: SmartIF::pRef.
       Can be disabled with the macros GAUDI_V22_API and NEW_SMARTIF.
     - Added a temporary hack to allow the print out of a SmartIF instance.

    ! 2009-05-06 - Marco Clemencic
     - Simplified the implementation of SmartIF, removing the unnecessary base
       class. It requires some more code duplication in the implementation of
       SmartIF<IInterface>.
       Part of the simplification comes from auto_ptr and the Boost smart pointers.
       Note: NOT backward compatible.

    ! 2009-04-27 - Marco Clemencic
     - Added specific macros to disable specific backward compatibility hacks.
       The hacks are all enabled with the preprocessor macro GAUDI_V20_COMPAT,
       and they are all disabled if the macro is not defined.
       Each of them can be disabled independently of the others using the
       following macros (enabled with the same CMTEXTRATAG):
       - G21_NEW_INTERFACES: new interfaces and interfaces ids
       - G21_HIDE_SYMBOLS: enable symbol visibility control
       - G21_NO_ENDREQ: remove the obsolete endreq
       Some hacks are disabled by the macro GAUDI_V22_API and can be independently
       disabled with the macros:
       - G22_NEW_SVCLOCATOR: backward incompatible changes to ISvcLocator etc.
       Obsolete/deprecated methods and functions (kept with GAUDI_V20_COMPAT)
       can be removed with the macros G21_NO_DEPRECATED and G22_NO_DEPRECATED.

    ================ GaudiKernel v27r0 ====================================
    ! 2009-04-08 - Marco Clemencic
     - Fixed bug #47258: gaudirun.py -o option.opts option.py introduces
                         explicit \n and \t in strings

    ! 2009-04-08 - Marco Clemencic, Vanya Belyaev
     - Fixed bug #48401: No dictionaries for IStatSvc and IChronoSvc

    ! 2009-04-07 - Marco Clemencic
     - Moved back the namespace MSG to the global namespace.

    ! 2009-04-06 - Charles Leggett
     - Fixed bug #48889: Copy and paste errors in MinimalEventLoopMgr

    ! 2009-04-06 - Marco Clemencic
     - Renamed back the namespace Msg to MSG and moved it into the namespace Gaudi.
       The backward compatibility is obtained with a namespace alias, that is
       enabled with GAUDI_V20_COMPAT and can be selectively disabled with the macro
       NO_OLD_MSG_NAMESPACE.
     - Renamed back INamed to INamedInterface.

    ! 2009-04-02 - Charles Leggett
     - Patch #2867: Propagate finalize errors of sub-algorithms.
     - Patch #2871: Propagate errors in Property callbacks.
       Changed the return value of Property::useUpdateHandler() and added a
       try-catch to trap exceptions and return a failure in that case.

    ! 2009-03-18 - Marco Clemencic
     - Minor change in Service::service<T> to avoid a problem with an old gccxml
       (ROOT 5.18).

    ! 2009-03-13 - Marco Clemencic
     - Task #9061: Introduction of component managers
       - Added the IComponentManager interface to allow a common and generic
         handling of managers. A basic implementation is provided too
         (currently used only by ServiceManager and AlgorithmManager)
         The FSM transitions are accessed through the IStateful interface, instead
         of specific methods like initializeServices or finalizeAlgorithms.
     - Simplified the interfaces ISvcLocator, ISvcManager, IAlgManager reducing
       the methods. The new format is enabled with the cpp macro GAUDI_V22_API.
       The main function now returns a SmartIF instead of a StatusCode.
     - Added a templated base class (CommonMessaging) to instrument classes with
       common messaging functionalities: msgSvc(), caching of the message stream,
       info(), etc.
     - Disabled the constructor of InterfaceID from a long (conditional to
       GAUDI_V20_COMPAT). The result was not correct.
     - Removed "void** operator& ()" from SmartIF because prevents the creation of
       std::list<SmartIF<T> >.
     - Replaced the small class "ListItem" with a more explicit "TypeNameString"
       with the same implementation.
     - Code adapted to the changes in the API.

    ! 2009-03-05 - Marco Clemencic
     - Added a macro to disable the longlong typedef: NO_LONGLONG_TYPEDEF.

    ! 2009-02-19 - Marco Clemencic
     - Patch #2790: Rename the namespace MSG to Msg

    ! 2009-02-06 - Marco Clemencic
     - Moved the implementation of the methods addRef and release to the templated
       base class implements<> (avoids duplication).
     - Modified implements.h to use preprocessor macros instead of replicated code.
     - Fixed a problem with MinimalEventLoopMgr::executeEvent. An AbortEvent
       incident fired by the last top alg in the list caused the skipping of the
       following event.

    ! 2009-01-30 - Marco Clemencic
     - Fixed compilation warnings when using Boost 1.38 (Spirit changed includes).
     - Replaced all the occurrences of endreq with endmsg. Removed endreq and added
       a macro endreq for backward compatibility (enabled with -DGAUDI_V20_COMPAT).

    ! 2009-01-29 - Marco Clemencic, Sebastien Binet
     - Symbol visibility (includes patch #2641)
       Added the preprocessor macros GAUDI_API, GAUDI_EXPORT, GAUDI_IMPORT and
       GAUDI_LOCAL to allow the decoration of classes and functions with visibility
       attributes.
       Decorated all the classes and functions that needs to be exported. This means
       essentially:
         - classes with at least one method in a .cpp file
         - abstract/virtual classes (to have the virtual destructor only in one
           place, to allow a correct dynamic_cast)
         - non-inline functions (i.e. implemented in .cpp)
         - all the classes that are part of an hierarchy that has to be navigated
           with dynamic_cast
       Usually it is not needed to decorate the fully-inlined classes/functions and
       the templated ones (unless they are using globals or are not completely
       implemented in the .h).
       In some cases it is enough to decorate only the non-inline methods of a
       class, mainly if the ratio non-inline/inline is small.

    ! 2009-01-29 - Marco Clemencic
     - Restored the special implementation of queryInterface for PropertyMgr.

    ! 2009-01-23 - Marco Clemencic
     - Fixes
       - added Boost_linkopts_date_time to avoid a compilation problem on win32
         with the LCGCMT 56 candidate (Boost 1.37)
       - removed fake declaration of mpl_::na (Boost) used for GCCXML
       - constantness problems in the new code discovered by gcc 4.3
       - warning about non specified base class in a copy constructor

    ! 2009-01-22 - Marco Clemencic
     - Introduced Boost Meta Programming Library (MPL) code to allow automatic
       generation of queryInterface methods.
       - modified IInterface to provide the needed basic typedefs
       - added the class Gaudi::InterfaceId to collect the list of interfaces
         implemented
       - added the templated classes extend_interfaces#, implements#, extends#
         - extend_interfaces#: used to write interfaces that inherits from other
                               interfaces (IInterface too)
         - implements#       : used to write concrete classes based on interfaces
                               only
         - extends#          : used to write concrete classes that extend concrete
                               classes with other interfaces (the constructor of the
                               base class must be called via the base_class typedef)
         if these classes are used, the method queryInterface is generated
         automatically.
       - added the preprocessor macro DeclareInterfaceID to declare the interface id
         for the interface; it must be put in the public section of the interface
         declaration using the interface as first argument, then major and minor
         versions:

           class IMyFunctionality: virtual public extendInterfaces1<IInterface> {
           public:
             DeclareIterfaceID(IMyFunctionality,1,0);
           };

       - modified the interfaces to use the new functionalities
       - NOTE: An updated interfaces does not require changes in the concrete
               implementations if GAUDI_V20_COMPAT is enabled. On the other hand, an
               adapted concrete class requires that all its interfaces are adapted.
       - added the (automatically generated) method IInterface::getInterfaceNames
         which returns a vector with the names of the interfaces implemented by the
         component
       - all the IID_* constants had to be removed to avoid conflicts with the IDs
         generated with DeclareIterfaceID (note that they are not needed even in
         v20-compatible code)
     - Renamed INamedInterface to INamed. The old header and a typedef are provided
       for backward compatibility (only if the macro GAUDI_V20_COMPAT is used).
     - Removed the obsolete ITime.h, TimePoint.h and Algorithm.icc.

    ================ GaudiKernel v26r1 ====================================
    ! 2008-12-16 - Marco Clemencic
     - Modified the Configurable.getValuedProperties logic to use all the explicitly
       set properties and not only those different from the defaults.

    ! 2008-12-15 - Marco Clemencic
     - Added the possibility of declaring "passive" dependencies between
       ConfigurableUser instances (i.e. C.U.s from which the properties are taken).
       The dependency is declared with the class data member
       __queried_configurables__.
     - Modified Python logging formatter of configurables to add the prefix ("#") to
       each printed line.

    ! 2008-12-10 - Marcus Frank
     - Patch #2699: First version of run records service
       Generalize DataIncident to also pass arbitrary parameters.

    ! 2008-12-09 - Marco Clemencic
     - Fixed minor problem in Configurable.__new__ for ConfigurableUser.

    ! 2008-12-07 - Marco Clemencic
     - Fixed compilation warning with gcc 4.3.

    ! 2008-12-05 - Marco Clemencic
     - Improved the logic of ConfigurableUser.propagateProperty (see the code for
       details).

    ! 2008-12-01 - Marco Clemencic
     - Fixed bug #44504. Inconsistent default for createIf flag for services.
       Set the default of the flag to "true" in both IServiceLocator::service
       signatures.
     - Fixed bug #44279. Ambiguous signature in setProperty functions
       Removed the redundant declarations.
     - Fixed problems with ToolHandles.

    ! 2008-11-27 - Marco Clemencic
     - Fixed compilation problems with ROOT 5.21/06.

    ================ GaudiKernel v26r0 ====================================
    ! 2008-11-13 - Pere Mato
     - Added the functions pushCurrentDataObject and popCurrentDataObject, taken
       from GaudiPoolDb.

    ! 2008-11-12 - Marco Clemencic
     - Added the possibility of specifying post-config actions (functions to be
       called after the call of all __apply_configuration__ methods) with the
       functions appendPostConfigAction and removePostConfigAction from
       GaudiKernel.Configurable (exposed via Gaudi.Configuration too).

    ! 2008-11-11 - Marco Clemencic
     - Added a small script (make_patch.py) to simplify the generation of patches.

    ! 2008-11-10 - Marco Clemencic
     - Minor change to ISvcManager to allow enable/disable of the initialization
       loop check.

    ! 2008-11-07 - Marco Clemencic
     - Added automatic registration of ConfigurableUser specializations to the
       database of configurables.

    ! 2008-11-06 - Marco Clemencic
     - Re-enabled the GaudiHandleProprtyProxy.
     - Modified the ConfigurableUser base class so that the ConfigurableUser classes
       declared as used are not active by default and they get activated the when
       they get instantiated explicitly. The test has been updated too.

    ! 2008-11-01 - Marco Clemencic
     - Fixed bug #43420. IPartPropSvc not accessible from Python
       Added the missing interface to the dictionary.

    ! 2008-10-30 - Marco Clemencic
     - Fixed a compilation problem on gcc4.3 with properties of type vector<pair>.
       (order of specializations in GaudiKernel/ToStream.h)
     - Replaced operator<<(MsgStream,vector) with the one in GaudiKernel/SerializeSTL.h
     - Modified the base class ConfigurableUser to allow automatic apply. If the
       ConfigurableUser derived class should touch other ConfigurableUser instances,
       the classes must be added to the class data member __used_configurables__
       (see tests/scripts/test_configurable_users.py in the package Gaudi).
     - Added the function GaudiKernel.Configurable.applyConfigurableUsers() which
       actually does the job of calling the apply method of all the ConfigurableUser
       instances.
     - Added the methods getProp and setProp to Configurable (LHCb contibution) and
       propagateProperty and propagateProperties to ConfigurableUsers (adaptations from
       LHCb contributions).

    ! 2008-10-28 - Marco Clemencic
     - Fixed bug #43314. Memory leak in StatusCode
       Added protection against self-assignment and delete of the owned
       IssueSeverity instance.

    ! 2008-10-27 - Marco Clemencic
     - Fixed warnings reported by gcc 4.3:
       - type qualifiers ignored on function return type
       - ../src/Lib/StatusCode.cpp:59: warning: the address of ‘addresses’ will
         always evaluate as ‘true’
       - ISO C++ forbids casting between pointer-to-function and pointer-to-object
         (only active for gcc >= 4)
     - Modified ConfigurableAlgTool.toStringProperty to use getFullName (to get rid
       of the parent name in front of the instance name).
     - Fixed a glitch in Configurable.__str__ when the property is a GaudiHandle.
     - Do not use the full path to genconf.exe with install area.
     - Fixed compilation errors and some warnings on gcc 4.3.

    ! 2008-10-23 - Marco Clemencic
     - Reverted old implementation of the reinitialize method of Algorithm, Service
       and AlgTool, i.e. do nothing. Fixes bug #39706.
     - Fixed bug #42428. Properties of clones are not cloned.
       - Modified the method clone to create copies of the properties if they are of
         types: [ str, list, dict, tuple ].
     - Fixed bug #43065. Error when unpickling GaudiHandles.
       - Modified the constructor of GaudiHandle to accept a GaudiHandle (or any
         instance with the method "toStringProperty") as argument.

    ! 2008-10-21 - Marco Clemencic
     - Improvements in the logging of GaudiKernel.ProcessJobOptions. "Print OFF" and
       "print ON" can be obtained using the GaudiKernel.ProcessJobOptions.PrintOn and
       GaudiKernel.ProcessJobOptions.PrintOff functions.

    ! 2008-10-20 - Marco Clemencic
     - Fixed the cast of errno from "int" to "unsigned long". (Fixes bug #25460)

    ! 2008-10-17 - Sebastien Binet
     - Fixed bug #42005. System::typeinfoName is missing 'signed char'
       - Added the missing case.

    ! 2008-10-17 - Marco Clemencic
     - Patch #2303. Improve/extend IAlgorithm interface
       Added the methods
        - setExecuted
        - isEnabled
        - filterPassed
        - setFilterPassed
     - Fixed bug #39846. gaudirun.py creates invalid entries in flattened options
       Modified filter "getNeededConfigurables" (GaudiKernel.Proxy.Configurable) to
       exclude ConfigurableUser instances.

    ! 2008-10-15 - Marco Clemencic
     - Excluded a couple of problematic methods from the dictionary (not preseent with
       ROOT 5.18, but causing problems with ROOT 5.21).
     - Fixed a problem with patch #2261. The usage of "id" for the aliases was
       conflicting with its usage for the DataObject factories.

    ! 2008-10-10 - Vanya Belyaev
     - Patch #2073: SharedObjectsContainer and 'blind' access to TYPE::Container &
                    TYPE::Selection
       Added SharedObjectsContainer.

    ! 2008-10-09 - Pere Mato
     - Patch #2261. Introducing name alias for Algorithms and Services
       Added the new macros DECLARE_NAMED_ALGORITHM_FACTORY(type,name) to be used
       instead of the current DECLARE_ALGORITHM_FACTORY(type) for algorithms with
       templates. Similarly for Services.

    ! 2008-10-09 - Marco Clemencic
     - Modified the return type of the "size" methods of ObjectContainerBase,
       KeyedContainer, ObjectList and ObjectVector to be size_t (i.e. "unsigned long")
       instead of long.
       It avoids some compilation warnings.

    ! 2008-10-09 - Vanya Belyaev
     - Patch #2058. Extensions for AIDA::TProfile1D
       IHistogramSvc : few new methods are added for booking of 1D-profiles with
                       Y-range and options

    ! 2008-10-03 - Marco Clemencic
     - Added ITHistSvc::getGraphs(), needed by patch #1963.

    ! 2008-10-01 - Marco Clemencic
     - Minor change in System::backTrace interface.

    ! 2008-10-01 - Frank Winklmeier
     - Patch #1797: Backtrace utility for System
       Generalized version of the code taken from IssueLogger::getTraceBack()
       (GaudiSvc).
     - Patch #1796: Performance improvement for message reporting

    ! 2008-08-06 - Marco Clemencic
     - Fixed bug #39809 (wrong configuration of public tools).

    ! 2008-08-05 - Marco Clemencic
     - Fixed bug #39250. Cannot use configurable instances as values for properties
                         of type map<str,str>.
     - Fixed bug #39117. gaudirun.py export to old options does not handle correctly
                         GaudiHandles.
       Added the method getFullName.
     - Fixed bug #39116. gaudirun.py export to old options prints '#' instead of '//'
       The fix required a review of the way messages are printed across the whole
       Configurables machinery. The Python standard logging module is now used and
       the customization in GaudiKernel.Logging has been removed.
       In printout in Python job option files should be done with the log instance
       accessible from Gaudi.Configuration.

    ================ GaudiKernel v25r2 ====================================

     - Added the interface IEventTimeDecoder (from LHCb detector description), and
       the Reflex dictionary for it.

    ! 2008-07-15 - Marco Clemencic
     - Fixed bug #38868. MinimalEventLoopMgr does not restart algorithms

       Fixed the implementation of reinitialize too.

    ! 2008-07-15 - Gerhard Raven
     - Fixed bug #38855. Inconsistent check in Service::sysRestart.
       Fixed a the result of a bad cut & paste.

    ! 2008-07-15 - Vanya Belyaev

       Added a check in StatEntity::addFlag to avoid floating point exceptions
       (underflows).

    ! 2008-07-11 - Charles Leggett
     - requirements: tweak genconfig_cmd macro to work with GAUDI_ATLAS tag

    ! 2008-06-25 - Marco Clemencic
     - Fixed bug #38206: gaudirun.py fails to set a list property from a property
                         reference.
     - Fixed bug #38194: gaudirun.py expands too many environment variables
       Avoid to expand the environment variables in the strings.

    ================ GaudiKernel v25r0 ====================================
    ! 2008-06-12 - Marco Clemencic
     - Modified the logic behind IFileAccess: the implementation must be able to
       tell which protocols it can handle.

    ! 2008-06-10 - Charles Leggett, Marco Clemencic
     - Fixed bug #37690. message svc release() in Auditor destructor
       - Moved the call the message service release to the finalize method, where it
         should be.

    ! 2008-06-10 - Marco Clemencic
     - Added platform-independent sleep functions:
       - Gaudi::Sleep(int)
       - Gaudi::NanoSleep(long long)

    ! 2008-06-06 - Marco Clemencic
     - Fixed Windows compilation warning (caused by patch #1756).

    ! 2008-06-05 - Marco Clemencic
     - Fixed bug #36742. Cannot pickle options using "PropertyReference"
     - Fixed a problem on osx105 (Undefined symbols: _environ).
     - Fixed bug #37479. gaudirun.py fails parsing old option lines with comments
                         and quotes.
     - Fixed bug #37488. importOptions does not expand environment variables.
     - Fixed bug #35347. Cannot import 2 Python option files with the same name.
       - Used execfile instead of __import__ for Python modules, following Paolo's
         suggestion).
     - Fixed bug #35913. Configurables type checking fails on Gaudi::Histo1DDef.
       - Fixed avoiding that tuples and lists are treated the same way.
     - Fixed bug #34769. Assigning a configurable to a list property does not fail.
       - Values for properties expecting lists, tuples and dictionaries must match
         the type (before it was possible to set a list from an iterable object).
     - Fixed handling of files starting with '#!' in gaudirun.py

    ! 2008-06-04 - Marco Clemencic
     - Fixed the last place where dylib was used on OSX (DsoUtils.h).

    ! 2008-06-04 - Charles Leggett
     - Patch #1865. Better printouts for HistorySvc.
       - 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 #1260.moved the MinimalEventLoopMgr from GaudiSvc to GaudiKernel. The factory
       for this service is still in GaudiSvc

    ! 2007-08-06 - Vanya Belyaev
     - 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
     - patch #1250.
       Removed the default constructor of Service because it is causing a memory
       leak in Reflex.

    ! 2007-07-24 - Vanya Belyaev
     - patch #1227.
       Added the functions "Gaudi::Utils::setProperty(IInterface*,...)", simpler
       counterparts of "Gaudi::Utils::setProperty(IProperty*,...)".

    ! 2007-07-23 - Vanya Belyaev
     - patch #1226.
       * SmartIFBase<TYPE>:
         + explicitely disable copy constructor and assignement
         + add "checking operator", operator!()
       * SmartIF<TYPE> and SmartIF<IInterface>
         + add "const" into copy constructor
         + add the constructor from underlying pointer
         + add "const" into standard assignement
         + add "const" into template assignemet
         + remove line duplicates between standard assignement and assignement
           from the regular pointer
         + fix typo in return type of assignement from the base
         + add "checking operator", operator!()

    ! 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.

    ! 2007-05-23 - Marco Clemencic
     - patch #1168. Added specialization for void* to GaudiUtils::Hash.

    ! 2007-05-23 - Charles Leggett
     - patch #1176. Added few missing functions in ITHistSvc
       (already present in THistSvc)

    ! 2007-05-23 - Vanya Belyaev
     - patch #1161. Improvements and clean-up in StatEntity:
        - 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

    ! 2007-05-23 - Marco Clemencic
     - patch #1160. Changed the returned value of
        - Algorithm::setExecuted()
        - Algorithm::resetExecuted()
        - Algorithm::setFilterPassed()
       from StatusCode to void.

    ! 2007-05-22 - Marco Clemencic
     - patch #1166. Splitted ParseVectors.cpp in 6 pieces:
        * ParseVectorsBool.cpp
        * 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
     - patch #1136: Updates to Algorithm and AlgTool required for
       changes in GaudiAlg for automatic registration of data to the
       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

    ! 2007-05-15 - Sebastien Binet
     - patch #1129: Add the method outputLevel() to Auditor.

    ! 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
     - fixed warning for gcc 4 (on MacOSX) about non-existing virtual
       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.

    ! 2007-04-09 - Marco Clemencic
     - patch #1125. Fixed INamedInterface in order to provide the right
       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();

    ================ GaudiKernel v22r2 ====================================
    ! 2007-03-14 - Sebastien Binet
     - Patch #1081 (fix to bug #24704): fix the crash that happens when
       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).

    ! 2007-02-26 - Sebastien Binet

       could be dyn-casted.

    ! 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.

    ! 2007-02-14 - Vanya BELYAEV
     Patch #1001
     - a) couple of fixes, which allows to retrieve the private tools not

    ! 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.

     Patch #1007
     - turned the templated member functions operator << (T&) and its
       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.

    ! 2006-11-26 - 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.

       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).

       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.

       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:

       iterator pointers as arguments

    ================ GaudiKernel v20r6 ====================================

     - 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

     - 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

    ! 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.

       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

     - 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.

     - 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).

    ! 2005-07-25 - Hubert Degaudenzi
     - fixed bug #9475. Missing #include <stdexcept> (Mattias Ellert).

    ! 2005-07-25 - Hubert Degaudenzi

       gccxml inputs in new subdirectory dict
       output id a dictionary DLL called "GaudiKernelDict"
       Reflex dictionary produced in parallel: "GaudiKernelRflxDict"
     - Fix inline bug in SmartDataPtr (function was never instantiated,
       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).

    ! 2005-07-18  Hubert Degaudenzi

     - 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=====================================

     - 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.

    ! 2004-09-13 - Markus Frank

    ================GaudiKernel v14r0=======================================
    ! 2003-07-03 - Markus Frank
      Major upgrade for use of POOL. Main change: extend technology specifier to
      int from unsigned char. Please note, that the changed interfaces are NOT BACKWARDS
      compatible. In particular in the converter area concrete user classes must
      support integer technology types. To create a compiler error, the converter
      base class does no longer have the method repSvcType().

      ModuleInfo.cpp        Remove signed/unsigned warning
      MsgStream.h           Added missing header file

     - Service.h: add ISvcLocator include for service() inline implementation

    ! 20020628 Pere Mato, Sebastien Ponce
     - Improved error reporting when loading dynamic libraries
     - Changed INFO messages to DEBUG when initializing services
     - Replaced forward class declarations by including the concerned header files. This
       is to aliviate user confusion.
     - Added function format(string fmt, ...) that can be used to format messages
       within the MsgStream class.
       Example:
       log << MSG::INFO << format("Evt: %8d Run: %8d", evt, run) << endmsg;
    	 Caveat: Since the unspecified argument list is used (...) the arguments can not
    	 be cheched for the correct type and possible conversions are not triggered.

    ! 20020529 Paolo Calafiura
     - Auditor.h: service() needs IServiceLocator header file

    ! 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

      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

      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.

    ! 20010430 - Markus Frank
      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
                               use the n-tuple service for these actions.
      NTupleImplementation.h/cpp dto.
      GaudiKernel/SmartDataPtr.h        Bug fix:

                                        if ( obj ) {...}
                                        Check succeeded if object is present however
                                        had bad type. Now this check checks for the
                                        presence of the object AND the data type.
                                        Moved pointer to object from SmartDataObjectPtr
                                        to SmartDataStorePtr (template class).
                                        Also moved corresponding check operators.
      GaudiKernel/SmartDataLocator.h    dto.

     - Fix Linux macro problem in Kernel.h (should be __linux, not linux).  Fix
       memory leak in Property.h. Fix a destructor problem in PropertyMgr.h by
       adding a std::vector<bool> to keep track of Property ownership. Add
       a protected state() member function to Service to allow subclasses to
       access the current state.

     -@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.

    ! 20010305 Pere Mato
     - 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.

    ! 20010223 Pere Mato
     - Changes to deal with the template specialization in the new version of GNU c++ compiler

    ! 20010208 Pere Mato
     - Modified System.cpp. Added suffix in the DLL name when loading

    ! 20000125 Pere Mato
     - Changed CLID& by CLID in Converter base class to avoid weird problems with some
       converters in Linux.
     - 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)

    ! 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.

    - 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

    - 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:
