    (description "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:

@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} tool as well as the runtime
library.")
