-      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).
