FWIW, +1 from IPython: we ship a private copy of argparse as well (we use 
it in several places but we want the basic ipython to be installable just 
with the stdlib). Steven was gracious enough to relicense it as BSD at our 


so we could ship this copy without any GPL incompatibilities, but we'd 
much rather rely on stdlib components.
