+a wide range of programming languages.  Unlike most programming major modes
+that use error-prone imperative code and regular expressions to determine
+what's what in your code, Combobulate uses Emacs 29's tree-sitter library.
+Tree-sitter maintains a concrete syntax tree of your code; it gives
+Combobulate absolute clarity of all aspects of your code, enabling more
+correct movement and editing than you would otherwise have.")
