   3  * @file adjustOCDBObject.C
   4  * @brief Tool to adjust properties of an OCDB object and write it back to OCDB.
   5  *
   6  * Usage:
   7  * <pre>
   8  *   aliroot -b -q adjustOCDBObject("file",
   9  *                                  targetCDB="local://$PWD",
  10  *                                  firstrun=-1,
  11  *                                  lastrun=-1,
  12  *                                  version=-1,
  13  *                                  subversion=-1,
  14  *                                  comment=NULL,
  15  *                                  responsible=NULL,
  16  *                                  alirootv=NULL)
  17  * </pre>
  18  *
  19  * The macro opens an OCDB entry directly as a file, changes properties
  20  * of the entry and uses the CDBmanager to write it back to some new
  21  * location.
