/**
 * @file EnableHLTInGRP.C
 * @author Artur Szostak <artursz@iafrica.com>
 * @ingroup alihlt_tutorial
 * @brief Patches GRP to process recorded data with HT in mode A.
 *
 * Usage:
 * <pre>
 *   aliroot -b -q 'EnableHLTInGRP.C(\<runNumber\>,\<grpPath\>)'
 * </pre>
 * Where \<runNumber\> is the number of the run the GRP corresponds to. This
 * can be found from the file name of the GRP entry of interest in the CDB.
 * \<grpPath\> is the path to the local GRP/GRP/Data directory where the GRP
 * entry to be modified is stored. Setting a value for \<grpPath\> is optional
 * and is the current working directory by default.
 *
 * Data recorded in mode A will not have the HT bit set in the GRP's active
 * detector mask. Trying to process such data with the HT framework will fail.
 * To be able to process such runs the GRP must be downloaded and patched with
 * this macro. It will set the HT bit in the GRP and write a new version of
 * the GRP with and incremented version number.
 * 
 * @return true if the macro completed successfully and false otherwise.
