libvldocking-java binary package in Ubuntu Trusty i386

 An application can be divided into sub-sets: the "dockables".
  - Each Dockable can be precisely positionned by the user, by a drag and drop
    gesture issued from its title bar.
  - Dockables can be grouped into tabbed panes.
 .
 Every Dockable is given a title bar with a set of common functions (and
 keyboard shortcuts):
  - Maximize / Restore : the Dockable takes all the available space on the
    desktop
  - Detach/Attach : the Dockable is extracted from its parent window
  - Iconify / Restore : the Dockable is changed into a side button : it appears
    only when the mouse is moved over it
  - Contextual pop-up menus : customizable title bars and tabs
  - Close / Closable tab
