+ * @class AliHLTQADataMakerRec
+ * Steering class for HLT QA for reconstruction.
+ *
+ * HLT QA allows to define multiple HLT detector QA plugins. Each plugin
+ * inherits through AliHLTQADataMakerBase from AliQADataMakerRec. Currently only
+ * the AliQADataMakerRec interface is supported in the HLT QA. It seems that
+ * AliQADataMakerSim is not relevant for HLT QA. However if so and at some
+ * point it is required please inform the author of this class.
+ *
+ * AliHLTQADataMakerRec keeps a list of detector plugins and redirects the
+ * different QA calls to all the plugins. At EndOfDetectorCycle all histograms
+ * are collected from the plugins after EndOfDetectorCycle has been invoked
+ * for every plugin.
+ *
+ * Detector plugins are added via the AliHLTModuleAgent. The optional function
+ * AliHLTModuleAgent::GetQAPlugins() has to return a string of blank separated
+ * class names.
+ * 
+ * HLT QA requires access to both the Esd and HLTEsd objects. Therefore the
+ * Exec function is overloaded in AliHLTQADataMakerRec. A specific hnadling
+ * in AliQAManager::RunOneEvent makes sure that an array of those objects
+ * is passed, the call is then redirected to 
+ * MakeESDs(AliESDEvent*, AliESDEvent*). Please note that the standard function
+ * MakeESDs(AliESDEvent*) is usually not the place for HLT QA.
