/**
 * @file changeRunValidity.C
 * @brief Change the run validity for OCDB entries. It increments the version of the input by 1,
 * in case there exists another object in the same folder with the same run validity. 
 * Please BE CAREFUL where you run it and where you copy the result. Check that the version of the
 * produced file is correct to enable its loading during the reconstruction.
 *
 * THIS IS A TEMPORARY SOLUTION UNTIL THE PENDOLINO STARTS RUNNING. WE SHOULD NOT RELY ON THIS MACRO.
 *
 * <pre>
 * Usage: aliroot -b -q -l changeRunValidity.C'("RunXXX_YYY_v?_s?.root",runmin,runmax)'
 * Default runmin = 0, runmax = 999999999
 *
 * Used for OCDB objects whose run validity is restrictic (run specific),
 * e.g. TPC/Calib/AltroConfig
 *      TPC/Calib/Temperature
 *      TPC/Calib/HighVoltage
 *      GRP/CTP/CTPtiming
