+//! This crate provides gsp language support for the [tree-sitter][] parsing library.
+//!
+//! Typically, you will use the [language][language func] function to add this language to a
+//! tree-sitter [Parser][], and then use the parser to parse some code:
+//!
+//! ```
+//! let code = "";
+//! let mut parser = tree_sitter::Parser::new();
+//! parser.set_language(tree_sitter_gsp::language()).expect("Error loading gsp grammar");
+//! let tree = parser.parse(code, None).unwrap();
+//! ```
