"""
Test framework to configure and drive a collection of rpkid.py and
irdbd.py instances under control of a master script.

Usage: python rpkid.py [ { -c | --config } config_file ]
                       [ { -h | --help } ]
                       [ { -y | --yaml }   yaml_script ]

Default config_file is testbed.conf, override with --config option.

Default yaml_script is testbed.yaml, override with -yaml option.

yaml_script is a YAML file describing the tests to be run, and is
intended to be implementation agnostic.

config_file contains settings for various implementation-specific
things that don't belong in yaml_script.
