Looking at the code I found it already
     parser = argparse.ArgumentParser(description=description,
                                      
formatter_class=argparse.ArgumentDefaultsHelpFormatter)

the only thing is that it displays also "default: None" which isn't 
probably very useful,
but it would easy to write my own formatter and pass it if I don't like 
this..
