/**
 * @class AliHLTReconstructor
 * AliHLTReconstructor AliRoot event reconstruction plugin for the HLT.
 * The AliHLTReconstructor holds an instance of the @ref AliHLTSystem
 * steering class. The actual reconstruction depends on the loaded component
 * libraries. Each library must implement a module agent (@ref AliHLTModuleAgent)
 * in order to provide information on the supported features and the
 * configurations to be run.
 *
 * The default component libraries which are loaded through the initialization
 * are determined by the @ref kHLTDefaultLibs array. The library loading can
 * be overridden by an option to the AliHLTReconstructor through the
 * <tt>SetOption</tt> method of <tt>AliReconstruction</tt>, e.g.
 * <pre>
 * AliReconstruction rec;
 * rec.SetOption("HLT", "libAliHLTSample.so");
 * </pre>
 * will only load <tt>libAliHLTSample.so</tt>
 * 
 * Optional arguments:<br>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formating -->
 * \li loglevel=<i>level</i><br>
 *     level can be a hex number encoding the @ref AliHLTComponentLogSeverity
 * \li alilog=off <br>
 *     disables the logging of HLT log messages through <tt>AliLog</tt> <br>
 *
 * For further information on the AliRoot reconstruction refer to the AliRoot
 * documentation, namely <tt>AliReconstruction</tt>.
