+//! Syntax Tree library used throughout the rust analyzer.
+//!
+//! Properties:
+//!   - easy and fast incremental re-parsing
+//!   - graceful handling of errors
+//!   - full-fidelity representation (*any* text can be precisely represented as
+//!     a syntax tree)
+//!
+//! For more information, see the [RFC]. Current implementation is inspired by
+//! the [Swift] one.
+//!
+//! The most interesting modules here are `syntax_node` (which defines concrete
+//! syntax tree) and `ast` (which defines abstract syntax tree on top of the
+//! CST). The actual parser live in a separate `parser` crate, though the
+//! lexer lives in this crate.
+//!
+//! See `api_walkthrough` test in this file for a quick API tour!
+//!
+//! [RFC]: <https://github.com/rust-lang/rfcs/pull/2256>
+//! [Swift]: <https://github.com/apple/swift/blob/13d593df6f359d0cb2fc81cfaac273297c539455/lib/Syntax/README.md>

+//! Implementation of incremental re-parsing.
+//!
+//! We use two simple strategies for this:
+//!   - if the edit modifies only a single token (like changing an identifier's
+//!     letter), we replace only this token.
+//!   - otherwise, we search for the nearest `{}` block which contains the edit
+//!     and try to parse only this block.
