We have one: `cargo`.
All commands are standard, you don't have to define scripts to build or run:
```bash
cargo init
cargo build
cargo run
cargo test
cargo publish
```
```toml
[package]
name = "scratch"
version = "0.1.0"
[dependencies]
serde = { version = "1.0.197", features = ["derive"] }
serde_json = "1.0.115"
```
