## Why not [rnr](https://github.com/ismaelgv/rnr)?
## Installation

Because this project scratches my particular itch and allows me to try/learn rust.
Once you have [`cargo`](https://doc.rust-lang.org/cargo/getting-started/installation.html) on your system:

```
cargo install muren
```

## Alternatives

- [rnr](https://github.com/ismaelgv/rnr)

Why am I implementing this then? Because this project scratches my particular itch and allows me to try/learn rust.
