def print_model_settings(locals_var, path=None, sys_arg=False):
    """
    Prints all variables in upper case in locals_var,
    except for T which usually stands for theano.tensor.
    If locals() passed as input to this method, will print
    all the variables in upper case defined so far, that is
    model settings.

    With `path` as an address to a directory it will _append_ it
    as a file named `model_settings.txt` as well.

    With `sys_arg` set to True, log information about Python, Numpy,
    and Theano and passed arguments to the script will be added too.
    args.pkl would be overwritten, specially in case of resuming a job.
    But again that wouldn't be much of a problem as all the passed args
    to the script except for '--resume' should be the same.

    With both `path` and `sys_arg` passed, dumps the theano.config.
