+Tree-sitter aims to be:
+
+@enumerate
+@item General enough to parse any programming language.
+@item Fast enough to parse on every keystroke in a text editor.
+@item Robust enough to provide useful results even in the presence of syntax
+errors.
+@item Dependency-free so that the runtime library (which is written in pure C)
+can be embedded in any application.
+@end enumerate
+
+This package includes the @command{tree-sitter} command-line tool.")
