The Clutter Accessibility Library is an implementation of the ATK, the Accessibility Toolkit, which exposes Clutter actors to accessibility tools. This allows not only writing accessible user interfaces, but also allows testing and verification frameworks based on A11Y technologies to inspect and test a Clutter scene graph. http://bugzilla.clutter-project.org/show_bug.cgi?id=2097 Signed-off-by: Emmanuele Bassi <ebassi@linux.intel.com>
