---The entry point to configuration.

---This module contains one function: `setup`, which is how you'll access all the ways to configure Pinnacle.

---The Pinnacle module.
---
---This module holds all the other configuration modules (Window, Input, etc.), and allows you to
---quit the compositor using the `quit` method.

---@field input Input
---@field output Output
---@field process Process
---@field tag Tag

---Setup Pinnacle.
---
---You must pass in a function that takes in the `Pinnacle` module object. The module is how you'll access the other config modules.
---
---Note: All the config modules are object instantiations, and their methods require you to use the colon operator
---instead of the dot operator to call them.
---
---If you want to do a multi-file config, you should have other files return a function taking in necessary modules.
---Or you could cheat and stick the modules into globals :TrollFace:
