def METHOD_NAME(self, master_appconfig):
    """ Configure  the specific aspect of the  application .  This
    method has a similar  meaning as master_configure() method and
    it should return a tuple (modified_flag,appconfig).
    This method must be  implemented in a derived class. Otherwise
    the submission will fail.
    Arguments:
      - master_appconfig is a result of the master job master_configure()
        method.
    In  case of  splitting this  method  will be  called for  each
    subjob  object  exactly  once  which  means that  it  will  be
    executed as many times as there are subjobs.
    If there  is no splitting  this method will be  called exactly
    once, after  master_configure().
    Transition from Ganga 4.0.x:
     - master_appconfig should be ignored (it is None anyway)
