def register_commands(self, subparsers):
<EOL>pass<EOL>
Add commands to a list of subparsers. This will be called by
Fissfc to add additional command targets from this plugin.

Each command added should follow the pattern:

parser = subparsers.add_parser('cmd', ...)
parser.add_argument(...)
...
parser.set_defaults(func=do_my_cmd)

where do_my_cmd is a function that takes one argument "args":, i.e:

def do_my_cmd(args):
    pass
