description = "LALR(1) parser generator for Ruby. Reads a `.y` grammar file and writes a generated Ruby parser module to the file given by -o. Pure code generation — does not execute the grammar's actions at generation time. The -O flag emits a binary debug table file. -E embeds racc's runtime into the generated parser. -C/--check-only validates the grammar without writing output. -v/--verbose writes a `.output` log alongside the parser. Distributed with Ruby and as a separate gem; the surface is essentially frozen."
