The first command-line argument is the action to take:
* 'start': Become a daemon and call `app.run()`.
* 'stop': Exit the daemon process specified in the PID file.
* 'restart': Stop, then start.

:param app: The application instance; see below.
:return: ``None``.
The `app` argument must have the following attributes:
* `stdin_path`, `stdout_path`, `stderr_path`: Filesystem paths
to open and replace the existing `sys.stdin`, `sys.stdout`,
`sys.stderr`.
* `pidfile_path`: Absolute filesystem path to a file that will
be used as the PID file for the daemon. If ``None``, no PID
file will be used.
* `pidfile_timeout`: Used as the default acquisition timeout
value supplied to the runner's PID lock file.
* `run`: Callable that will be invoked when the daemon is
started.

from the `app`.

The parser expects the first argument as the program name, the
second argument as the action to perform.
If the parser fails to parse the arguments, emit a usage
message and exit the program.
