code: def parse(self, context):
          
          context.args = context.parser.parse_args(context.argv)
docs: Parse command line arguments.
  
          This method relies on ``context.argv`` and ``context.early_parser``
          and produces ``context.args``. Note that ``.argv`` is modified by
          :meth:`preparse()` so it actually has _less_ things in it.
  
          The ``context.args`` object is the return value from argparse.
          It is the dict/object like namespace object.
