* **--dry-run:** If you want to run through an installation without actually
installing a package, you can use `--dry-run`. This will simulate the
installation and show you what would happen.
* **--download-only:** Download only, do not install packages.
* **--dev:** Install packages listed in `require-dev` (this is the default behavior).
* **--no-dev:** Skip installing packages listed in `require-dev`. The autoloader
generation skips the `autoload-dev` rules. Also see [COMPOSER_NO_DEV](#composer-no-dev).
