CliOptionSet class final

The options one subcommand reads: flags alone, valued with the argument after them (or --name=value).

The parser's first look, the same for every command. Each command answers an option that is not here with CliExit.usage before it reads anything else, so --knd=viewer is refused rather than dropped, and a test holds each set to the flags its usage text names, both ways.

Constructors
