//! This crate provides Bass 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_bass::language()).expect("Error loading Bass grammar");
//! let tree = parser.parse(code, None).unwrap();
//! ```
//!

//! [language func]: fn.language.html
