 Cot is an easy to use, modern, and fast web framework for Rust. It has been designed to be familiar if you've ever
 used [Django](https://www.djangoproject.com/), and easy to learn if you haven't. It's a batteries-included framework
 built on top of [axum](https://github.com/tokio-rs/axum).
