        ANTLR (ANother Tool for Language Recognition) is a powerful parser
        generator for reading, processing, executing, or translating structured
        text or binary files. It's widely used to build languages, tools, and
        frameworks. From a grammar, ANTLR generates a parser that can build and
        walk parse trees.
