The nightly compiler is required:
```bash
cargo +nightly build --release
```
A specific profile can also be used:
```bash
cargo +nightly build --profile unix -Z unstable-options
```
Available profiles are: `unix`, `windows` and `macos`.
Three profiles are defined: `unix`, `windows` and `macos`.
The release build is optimized for size. It can be changed to optimize on speed instead.
