 * @brief Sample macro for the use of the HOMERManager
 *
 * Usage:
 * <pre>
 *   aliroot -l HOMERManager.C 
 * </pre>
 *
 * This macro illustrates the usage of the AliHLTHOMERManager in order
 * to on-line read events outside the HLT.
 *
 * This macro can be run inside the
 * <ul>
 *    <li>DAQ/DCS(ACR) network</li>
 *    <li>HLT network</li>
 *    <li>CERN GPN network</li>
 * </ul>
 * 
 * See AliHLTHOMERManager for detailed description.
