# Buzz

The language magusfiles are written in (the `.buzz` engine).

## Elsewhere

Buzz is an upstream language with its own interpreter, written in Zig (buzz-lang.dev). magus
embeds a Go implementation of it, and language changes there follow upstream Buzz.

## Example

```sh
magus buzz -e 'import "std"; fun main(args: [str]) > void { std\print("hello"); }'
```
