For more on creating a custom subcommand, see [the cargo

book](https://doc.rust-lang.org/cargo/reference/external-tools.html#custom-subcommands).

The crate [`clap-cargo`](https://github.com/crate-ci/clap-cargo) can help in

mimicking cargo's interface.

The help looks like:

```console

$ cargo-example --help

Usage: cargo <COMMAND>

Commands:

  example  A simple to use, efficient, and full-featured Command Line Argument Parser

  help     Print this message or the help of the given subcommand(s)

Options:

  -h, --help  Print help

$ cargo-example example --help

A simple to use, efficient, and full-featured Command Line Argument Parser

Usage: cargo example [OPTIONS]

Options:

      --manifest-path <PATH>

  -h, --help                  Print help

  -V, --version               Print version

```

Then to directly invoke the command, run:

```console

$ cargo-example example

Some("Cargo.toml")

```
