Rust Reference still talks about #[deriving(...)], instead of #[derive(...)]

It seems that #[deriving(Show)] has stopped defining the Show trait for structs.

In the code below, if I remove the #[cfg(skip)] before the explicit Show derivation, the program runs correctly.

    fn fmt(&self, f: &mut Formatter) -> Result<(), Error> {
        f.write_str("Stuff()")
    }
}

fn main() {
    let x = Stuff;
    assert_eq!(format!("{:?}", x), "Stuff()");
}

Ah, sorry. This is a doc issue. #[derive(Show)] works. The Rust reference still describes deriving.
