"""
rocRoller performance tracking suite command line interface.

New, modular way to add subcommands to rrperf:

Make a top-level module inside rrperf. It must implement get_args() and run().

- get_args() should take an argparse.ArgumentParser and add all command-line arguments
  to it.
- run() should take the parsed arguments object and run the relevant command.

The docstring for the module will be used as the description for the subcommand (under
`rrperf <command> --help`).  The docstring for the `run` function will be used as the
 help text for the subcommand (under `rrperf --help`).
