 * @file raw-hlt-its.C
 * @brief HLT data replay in AliReconstruction
 *
 * <pre>
 * Usage: aliroot -b -q ra-hlt-it.C'("raw.root","cdburi", minevent, maxevent)'
 * Parameter:
 *     input     default 'raw.root'
 *     cdburi    default 'raw://'
 *     minevent  default 0  (no restriction)
 *     maxevent  default -1 (no restriction)
 *     usepredefined  default false
 * </pre>
 *
 * Replay of raw data through the ITS chain. The reduced configuration
 * consists of SPD clusterfinder, SPD vetexer and histogram component.
 * Histograms are written to file 'histos.root'.
 *
 * The predefined chain can be run by specifying the 'GLOBAL-vertexhisto'
 * configuration. In that case also TPC tracking, ITS tracking, generation
 * of ESD and GlobalVertexer are executed as input to the histogramming
 * component.
