+/**
+ * @class AliHLTLogging
+ * Basic logging class. All classes inherit the besic HLT logging functionality.
+ * Logging levels are controlled by a global logging filter and a local logging
+ * filter.
+ *
+ * @section alihlt_logging_levels Logging Levels
+ * Logging levels are switched by a bit pattern, AliHLTComponentLogSeverity {
+ * - ::kHLTLogNone no logging (0)
+ * - ::kHLTLogBenchmark benchmark messages (0x1)
+ * - ::kHLTLogDebug debug messages (0x2)
+ * - ::kHLTLogInfo info messages (0x4)
+ * - ::kHLTLogWarning warning messages (0x8)
+ * - ::kHLTLogError error messages (0x10)
+ * - ::kHLTLogFatal fatal error messages (0x20)
+ * - ::kHLTLogImportant few important messages not to be filtered out (0x40)
+ * - ::kHLTLogAll special value to enable all messages (0x7f)
+ * - ::kHLTLogDefault the default logging level: Warning, Error, Fatal, Important (0x79)
+ *
+ * @section alihlt_logging_filter Logging Filters
+ * The class provides a global and a local logging filter, the AND beween both
+ * defines whether a message is printed or not.
+ *
+ * The global filter is by default set to ::kHLTLogAll. Please note that AliHLTSystem
+ * changes the global logging level to ::kHLTLogDefault. The global filter can be
+ * adjusted by means of SetGlobalLoggingLevel().
+ *
+ * The local filter is set to ::kHLTLogAll and can be adjusted by
+ * SetLocalLoggingLevel(). The default can be changed for all objects by
+ * SetLocalLoggingDefault(). Please note that a change of the default level only
+ * applies to objects generated after the change of the default.
+ *
+ * @section alihlt_logging_external Redirection
+ * - external logging function
+ * - keyword
+ *
+ * @section alihlt_logging_aliroot AliRoot Redirection
+ * - switching of redirection
+ * - logging options in AliSimulation/AliReconstruction
