I'm seeing the following pattern:

```
if (flags.master.isNone()) {
  cerr << flags.usage("Missing required option --master") << endl;
  return EXIT_FAILURE;
}
```

Why not leverage EXIT here?

```
if (flags.master.isNone()) {
  EXIT(EXIT_FAILURE) << flags.usage("Missing required option --master");
}
```

I'm assuming there's probably also a ticket or TODO somewhere to be able to 
declare when an argument is required to avoid these manual checks entirely. :)
