 * @file adjustOCDBObject.C
 * @brief Tool to adjust properties of an OCDB object and write it back to OCDB.

 * Usage:

 *   aliroot -b -q adjustOCDBObject("file",
 *                                  targetCDB="local://$PWD",
 *                                  firstrun=-1,
 *                                  lastrun=-1,
 *                                  version=-1,
 *                                  subversion=-1,

 *                                  alirootv=NULL) 
 * </pre>
 *
 * The macro opens an OCDB entry directly as a file, changes properties
 * of the entry and uses the CDBmanager to write it back to some new
 * location.
