liblablgtk-extras-ocaml-dev 1.4-2 (amd64 binary) in ubuntu trusty

 Lablgtk-extras is a collection of libraries and modules useful when
 developing OCaml/LablGtk2 applications. Most of the libraries come
 from Cameleon2:
  * Configwin: a library to easily create input dialog boxes,
  * Okey: a module to add handlers for key press events,
  * Gtksv_utils: a module to share configuration of colors, fonts,
    ..., between applications using LablGtkSourceView, with functions
    and boxes to make the user edit configuration of languages and
    source views.
