# Command-Line Application with `app-cli`

This Rust application demonstrates the use of the `app-cli` crate for building a command-line interface (CLI). The application allows users to register a person or a pet with specific command-line arguments.

## Features

- Register a person with first and last name.
- Register a pet with a pet name.
- Optional flag to indicate if the person is wearing a fluffy coat.

## Usage

### Register a Person

To register a person, use the `register-person` subcommand with the required `--first-name` (or aliases `-f`, `--fname`, `--firstname`) and `--last-name` (or aliases `-l`, `--lname`, `--lastname`) arguments.

```bash
cargo run -- register-person --first-name John --last-name Doe

or using the short aliases:

cargo run -- register-person -f John -l Doe

Register a Pet

To register a pet, use the register-pet subcommand with the required --pet-name argument.

cargo run -- register-pet --pet-name Fluffy

Optional Arguments

The --fluffy argument can be used with any subcommand to indicate if the person is wearing a fluffy coat.

cargo run -- register-person --first-name John --last-name Doe --fluffy
