+     "Tree-sitter is a parser generator tool and an incremental parsing
+library.  It can build a concrete syntax tree for a source file and efficiently
+update the syntax tree as the source file is edited.
+
+Tree-sitter aims to be:
+
+@itemize
+@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 itemize
+
+This package includes the @code{libtree-sitter} runtime library.
