[TimWillis]

Argparse documentation in 2.7 indicates support for an 'aliases' kwarg. (Fourth example down from http://docs.python.org/dev/library/argparse.html#sub-commands)

While aliases work as expected in 3.2, use in 2.7 results in TypeError: __init__() got an unexpected keyword argument 'aliases'

[TimWillis]

Attaching a patch which merges aliases code from 3.2 back into 2.7.

adding package author to nosy list

[bethard]

This is a new feature, not a bug, so I think the correct fix is to change the 2.7 documentation, since at this point 2.7 can only get bugfixes, not new features.

[merwok]

Agreed, this looks like a doc glitch.

[TimWillis]

The documentation appears to be up to date in the current 2.7 repository, so this can probably be marked as closed/fixed.

Ah, I did not see that your first message talked about the dev doc, which is 3.3.
