    longDescription =
      ''
        OCaml is the most popular variant of the Caml language.  From a
        language standpoint, it extends the core Caml language with a
        fully-fledged object-oriented layer, as well as a powerful module
        system, all connected by a sound, polymorphic type system featuring
        type inference.

        The OCaml system is an industrial-strength implementation of this
        language, featuring a high-performance native-code compiler (ocamlopt)
        for 9 processor architectures (IA32, PowerPC, AMD64, Alpha, Sparc,
        Mips, IA64, HPPA, StrongArm), as well as a bytecode compiler (ocamlc)
        and an interactive read-eval-print loop (ocaml) for quick development
        and portability.  The OCaml distribution includes a comprehensive
        standard library, a replay debugger (ocamldebug), lexer (ocamllex) and
        parser (ocamlyacc) generators, a pre-processor pretty-printer (camlp4)
        and a documentation generator (ocamldoc).
