cargo - The Rust package manager https://crates.io/ This will build cargo from source, which like rust, requires itself to bootstrap. This will build cargo using the installed rust and previously stable version of cargo. If you already have rust and cargo installed, this slackbuild will use these to bootstrap this version of cargo instead of a downloaded one. You can also force either behaviour through the LOCAL_BOOTSTRAP=yes|no parameter. LOCAL_BOOTSTRAP=no ./cargo.SlackBuild
