+//! Servo's compiler plugin/macro crate
+//!
+//! Attributes this crate provides:
+//!
+//!  - `#[derive(DenyPublicFields)]` : Forces all fields in a struct/enum to be private
+//!  - `#[derive(JSTraceable)]` : Auto-derives an implementation of `JSTraceable` for a struct in the script crate
+//!  - `#[must_root]` : Prevents data of the marked type from being used on the stack.
+//!                     See the lints module for more details
+//!  - `#[dom_struct]` : Implies #[derive(JSTraceable, DenyPublicFields)]`, and `#[must_root]`.
+//!                       Use this for structs that correspond to a DOM type
