            # handled by argparse directly, but there are cases where extra
            # processing is needed.  For example, "--foo name=value" the value
            # can be converted from "name=value" to {"name": "value"}.  This is
            # referred to as the "unpacking" process.  Once we've unpacked the
            # argument value, we have to decide how this is converted into
            # something that can be consumed by botocore.  Many times this is
            # just associating the key and value in the params dict as down
            # below.  Sometimes this can be more complicated, and subclasses
            # can customize as they need.
