//! A very, VERY WIP Smithay-based Wayland compositor.
//!
//! Pinnacle is heavily inspired by the [Awesome Window Manager](https://awesomewm.org),
//! and this is an attempt to make something akin to it for Wayland.
//!
//! While Pinnacle is not a library, this documentation serves to guide those who want to
//! contribute or learn how building something like this works.

#![deny(unused_imports)] // gonna force myself to keep stuff clean
