/**
 * @file publish-rawreader-data.C
 * @brief Publish data from the the RawReader provided by the AliReconstruction.
 *
 * Usage:
 * <pre>
 *   aliroot -b -q 'publish-rawreader-data.C("raw.root", 768, 769)' | tee publish-rawreader-data.log
 * </pre>
 *
 * This macro runs shows a use case of the AliHLTRawReaderPublisherComponent
 * An HLT chain is run inside the AliReconstruction and the DDL payload is
 * extracted from the AliRawReader in a given  equipment range.
 * Input can be either a root file or the path to the directory containing
 * the 'rawx' sub folders.
