+ * @defgroup alihlt_system HLT integration into AliRoot
+ * This section describes the HLT integration into AliRoot.
+ *
+ * @section alihlt_system_intro General Remarks
+ * The HLT analysis is organized in components which can also be used
+ * in off-line processing. Two different types of off-line applications
+ * can be distinguished:
+ * - AliRoot simulation (AliSimulation)
+ * - AliRoot reconstruction (AliReconstruction)
+ *
+ * In either case an HLT chain described by means of AliHLTConfiguration
+ * builds the core of any HLT application. Special components exist, which
+ * emulate the behavior of the components of the HLT on-line data
+ * transportation framework. Together with the analysis components, this
+ * allows the full emulation of the behavoir of HLT analysis chain off-line.
+ *
+ * More details how to setup up such a chain can be found:
+ * - The examples page under @ref tut_hltsystem
+ *
+ * @section alihlt_system_simulation AliRoot simulation
+ * HLT has a special role in the normal data flow of simulation and
+ * reconstruction. Since the HLT reconstruction and analysis runs on-line
+ * on the HLT farm, the raw data produced by HLT as a detector contains
+ * already reconstructed events. Consequently, the HLT response has to be
+ * simulated as well as the data of all other detectors.
+ *
+ * Since the detector data is needed, the HLT simulation is run at the
+ * end of AliSimulation.
+ *
+ * As a matter of fact, HLT always reconstructs data, <em><b>HLT simulation
+ * </b></em> means <em><b>HLT reconstruction embedded into AliRoot</b></em>.
+ *
+ * More Details an be found in the module:
+ * - @ref alihlt_aliroot_simulation
+ *
+ * @section alihlt_system_reconstruction AliRoot reconstruction
+ *
+ * Like all other ALICE detectors, HLT utilizes the AliReconstruction interface
+ * to implement a plugin for the AliRoot reconstruction. The reconstructor can be
+ * used to
+ * - run HLT analysis chains in the AliRoot reconstruction <br>
+ * This option is mainly intended for the development and debugging cycle. HLT
+ * chains can be defined by means of AliHLTConfiguration and can be run either
+ * stand-alone or embedded into the AliReconstruction cycle.
+ * - run the default analysis chains <br>
+ * HLT modules can define default analysis chains to be run during AliRoot
+ * reconstruction.
+ * - handle the HLTOUT data<br>
+ * The HLT output stream contains multiple data blocks produced by the various
+ * components of the HLT chain. Each block might need different and even
+ * detector specific processing, like e.g. the processing of ESD objects or the
+ * handling of compressed data.
+ *
+ * More Details an be found in the module:

+ * Main class for the HLT integration into AliRoot.
+ * @note This class is only used for the @ref alihlt_system.
+ *
+ * @section alihltsystem_overview Main functionality
+ * The class implements the main binding functionality to run HLT
+ * embedded in AliRoot:
+ * - creates handlers for HLT components (AliHLTComponentHandler)
+ * and configurations (AliHLTConfigurationHandler).
+ * - implements the creation of a task list from configurations
+ * - runs the tasks of the task list
+ * - implements the interface to AliHLTReconstructor and AliHLTSimulation
+ * - manages the registered module agents (AliHLTModuleAgent)
+ *
+ * @section alihltsystem_functions Main functions
+ * The following list gives the most important functions, see documentation
+ * of functions for details.
+ * - ScanOptions(const char*) initialize the system from arguments
+ * - BuildTaskList(const char*) build task list for a reconstruction chain
+ * - Run() processing loop for task list
+ * - Reconstruct() interface to AliHLTReconstructor
+ * - ProcessHLTOUT() process an HLTOUT colection
+ *
+ * @section alihltsystem_initialization Initialization
+ * AliHLTSystem is initialized with a list of component libraries which determine
+ * the actual functionality. See ScanOptions() for description of options.
+ *
+ * @section alihltsystem_usage Usage
+ * The class AliHLTPluginBase handles the global instance of AliHLTSystem,
+ * the instance is created and fetched like
+ * <pre>
+ * // setup the HLT system
+ * AliHLTSystem* pHLT=AliHLTPluginBase::GetInstance();
