    longDescription =
      '' Objective Caml 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 Objective Caml 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 Objective Caml
         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).
