```toml
[server]
address = "0.0.0.0:12345" # ip address to bind to
max_clients = 32 # max amount of connected clients

"In-house" libraries
- [`hui`, `hui-glium`, `hui-winit`](https://github.com/griffi-gh/hui): semi-imm.mode backend-agnostic ui system\

deprecated:
- ~~`kubi-udp`~~ eventually got replaced by `uflow` (https://github.com/lowquark/uflow) in #5
- ~~`kubi-pool`~~ decided there's no need to replace rayon for now
