ocaml-compiler-libs 4.04.0-2ubuntu4 (i386 binary) in ubuntu artful

 Objective (OCaml) is an implementation of the ML language, based on
 the Caml Light dialect extended with a complete class-based object system
 and a powerful module system in the style of Standard ML.

 This package contains several modules used internally by the OCaml
 compilers. They are not needed for normal OCaml development, but may
 be helpful in the development of certain applications.
