## Why
Mainly the lowest level reusable components abstracted during the development process of [opensound-org](https://github.com/orgs/opensound-org/repositories) projects. Of course, others may also find these things useful.
## How
You can:
```
cargo add est
```
Or in your `Cargo.toml`:
```toml
[dependencies]
est = "0.8"
```
