''
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).
