It is currently able to generate Haskell,\nAgda, C, C++, Java, and OCaml, as well as XML representations.\n\nGiven a LBNF grammar the tool produces:\n- an abstract syntax implementation\n- a case skeleton for the abstract syntax in the same language\n- an Alex, Ocamllex, JLex, or Flex lexer generator file\n- a Happy, Ocamlyacc, Menhir, ANTLR, CUP, or Bison parser generator file\n- a pretty-printer as a Haskell/Agda/C/C++/Java/Ocaml module\n- a Latex file containing a readable specification of the language\n\n*More information*: http://bnfc.digitalgrammars.com/\n\nInstallation\n------------\n\nSome binaries are available at https://github.com/BNFC/bnfc/releases.\nInstallation from the Haskell sources is possible via `stack` or `cabal`.\n\n### Installation via stack (recommended)\n\nYou need a running installation of\n[stack](https://docs.haskellstack.org/en/stable/install_and_upgrade/).\nTo install and run the latest version of\n[bnfc from stackage](https://www.stackage.org/package/BNFC),\nenter at the command line:\n\n```\n  stack ",
