libgail-3-dev 3.24.35-2ubuntu1 (ppc64el binary) in ubuntu lunar

 Gail implements ATK interfaces for GTK widgets which are dynamically
 loadable at runtime by a GTK application. Once loaded, those parts of
 an application that use standard GTK widgets will have a basic level
 of accessibility, without the need to modify the application at all.

 This package contains the development files for Gail.
