This package includes libatk-bridge, a library that bridges ATK to the new D-Bus based AT-SPI, as well as a corresponding module for gtk+ 2.x. Gtk+ 3.x now links against libatk-bridge directly rather than requiring it to be loaded as a module.

These libraries depend on the at-spi2-core code that contains the daemon for registering applications, D-Bus helper libraries and the AT-SPI D-Bus specifications.
