The double "--" isn't a standard, it's just what you get when you compose the two rules you quoted in your original email :-). "--" is supposed to mean, "stop doing option processing and treat everything after this as positional arguments". So tox really should see the first "--" and then treat the second as a positional argument. Instead it is throwing the second one away. That is definitely a bug in tox or whatever option parsing library it's using. -N _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
