libgail3.0-dev 2.99.3-0ubuntu1 (i386 binary) in ubuntu natty

 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.
