Option "--help" does not list all available options

[stephansann]

Hello

It would be nice if the command line option "--help" would list all available options.

At least missing are:
--relay
--clipboard (even though not working for me)

Current output:

% ./sendme --help                                                        
Send a file or directory between two machines, using blake3 verified streaming.

For all subcommands, you can specify a secret key using the IROH_SECRET environment variable. If you don't, a random one will be generated.

You can also specify a port for the magicsocket. If you don't, a random one will be chosen.

Usage: sendme <COMMAND>

Commands:
  send     Send a file or directory
  receive  Receive a file or directory [aliases: recv]
  help     Print this message or the help of the given subcommand(s)

Options:
  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

Thanks
Stephan

The helptext is auto-generated using the CLI-parser clap. It does list these options if you ask it about help like this: sendme send --help.

That said, it's possible we could make those options more discoverable. Perhaps we can add a text to the help saying something like "run sendme [Command] --help for more information on individual commands"?

@matheus23 thanks for the clarification.
And yes, the additional hint would be very valuable.

The issue here is that sendme is not, by default, built with the clipboard feature, and so the command does not exist in our release binaries.

We should consider adding clipboard as a default feature.
