# Error code E0498

The `plugin` attribute was malformed.

Erroneous code example:

    #![allow(unused)]
    #![feature(plugin)]
    #![plugin(foo(args))] // error: invalid argument
    #![plugin(bar="test")] // error: invalid argument
    fn main() {
    }

The `#[plugin]` attribute should take a single argument: the name of the plugin.

For example, for the plugin `foo`:

    #![feature(plugin)]
    #![plugin(foo)] // ok!

See the `plugin` feature section of the Unstable book for more details.
