This tool, called `argparse`, helps you easily handle command-line arguments in your C++ programs. Here’s how it benefits you You just need to include a single header file `argparse.hpp` and create an `ArgumentParser` object to start parsing command-line arguments.
- **Flexible Argument Types** You can add arguments with specific behaviors (e.g., required, default values, flags) using methods like `add_argument`, `default_value`, and `implicit_value`.
- **Help Messages** You can create subcommands and share arguments between parsers, similar to how tools like `git` work.
- **Customization**: You can customize prefix characters, assignment characters, and even format the usage output to suit your needs.

Overall, `argparse` simplifies the process of handling command-line arguments, making your program more user-friendly and flexible.
