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.
