Bug 877265 - Make dmcli parseable by python 2.6;r=ahal

            subparser = subparsers.add_parser(commandname, help=commandprops['help'])

            if commandprops.get('args'):

                for arg in commandprops['args']:

                    kwargs = { k: v for k,v in arg.items() if k is not 'name' }

                    # this is more elegant but doesn't work in python 2.6

                    # (which we still use on tbpl @ mozilla where we install

                    # this package)

                    # kwargs = { k: v for k,v in arg.items() if k is not 'name' }

                    kwargs = {}

                    for (k, v) in arg.items():

                        if k is not 'name':

                            kwargs[k] = v

                    subparser.add_argument(arg['name'], **kwargs)

            subparser.set_defaults(func=commandprops['function'])
