+//! HIR (previsouly known as descriptors) provides a high-level OO acess to Rust
+//! code.
+//!
+//! The principal difference between HIR and syntax trees is that HIR is bound
+//! to a particular crate instance. That is, it has cfg flags and features
+//! applied. So, there relation between syntax and HIR is many-to-one.
