## Overview

A small command-line utility reads the first argument, passes it to Segno to create a QR code, then saves the image as qrcode.png. The sole source file is excerpted; the external library is not part of this repository.

Main entry points: [`qrcode.py`](https://github.com/cjkennedyo/qr_code_generator/blob/main/qrcode.py) (QR generator)
