OPTIONS:
-h, --help Print help information
-V, --version Print version information
$ 03_04_subcommands_derive add bob

Because we used `command: Commands` instead of `command: Option<Commands>`:
```console
$ 03_04_subcommands_derive
? failed
clap [..]
A simple to use, efficient, and full-featured Command Line Argument Parser
USAGE:
03_04_subcommands_derive[EXE] <SUBCOMMAND>
OPTIONS:
-h, --help Print help information
-V, --version Print version information
SUBCOMMANDS:
add Adds files to myapp
help Print this message or the help of the given subcommand(s)
```
Because we added `#[clap(propagate_version = true)]`:
```console
$ 03_04_subcommands_derive --version
clap [..]
$ 03_04_subcommands_derive add --version
03_04_subcommands_derive[EXE]-add [..]
```
