    -l [<KIND>[:<MODIFIERS>]=]<NAME>[:<RENAME>]
                        Link the generated crate(s) to the specified native
                        library NAME. The optional KIND can be one of

                        Comma separated list of types of crates

                        lints are capped at this level
    -C, --codegen <OPT>[=<VALUE>]
                        Set a codegen option
    -V, --version       Print version info and exit
