-This is the initial CVS checkin of the Gnome Accessibility Project's
-Assistive Technology Service Provider Interface.
+D-Bus AT-SPI
+------------
-At the moment it does not include IDL for all of the SPI, but it does
-provide a prototype implementation of the core of the out-of-process
-accessibility service, the 'registry'.
+This version of at-spi is a major break from version 1.x.
+It has been completely rewritten to use D-Bus rather than
+ORBIT / CORBA for its transport protocol.
-Accessible applications will register with this registry service (via OAF)
-and adaptive/assistive technologies will register with the service as
-well, to indicate their interest in receiving UI events. ATs can also use
-the registry's services programmatically to query accessible applications.
+A page including instructions for testing, project status and
+TODO items is kept up to date at:
+ http://www.linuxfoundation.org/en/AT-SPI_on_D-Bus
-Running the test programs: ============================
+The mailing list used for general questions is:
-At the moment the only clients and 'apps' are the test at client and
-test app in the 'tests' subdirectory.
+ accessibility-atspi@lists.linux-foundation.org
-If you have a working ORBit2/OAF installation you can run the tests after
-adding the registryd directory to OAF's directory list with oaf-sysconf,
-or by installing Accessibility_Registry.oaf in your 'oafinfo' directory.
+For bug reports, feature requests, patches or enhancements please use
+the AT-SPI project on bugzilla.gnome.org. Use the at-spi2-atk component for
+bugs specific to this module.
-You can then run './at' and './app' from the 'test' directory, to see
-'app' register as an application, and 'at' as a listening client.
-OAF should take care of the job of bootstrapping the registry daemon
-('registryd') for you.
+ http://bugzilla.gnome.org
-At the moment app and at deregistration are broken, so you are advised
-to kill the registry daemon if you exit either 'at' or 'app' instances.
-You may run as many instances of each as you like, concurrently - you
-may find it useful to do so in separate terminal windows.
+A git repository with the latest development code is available at:
+ git://git.gnome.org/at-spi2-atk
-'at' connects to the registry as an event listener, then queries the
-service for the number of virtual desktops (currently always 0 or 1),
-and queries each desktop for the accessible applications it is running.
-It then prints out the name of each such application (as reported by the
-application's accessibility interfaces), and then waits to receive events.
+Code in this repository depends on at-spi2-core resources. The
+at-spi2-core repository can be found at:
-'app' connects to the registry as an application, then dispatches an
-event which the registry should relay to all registered listeners.
-Thus instances of 'app' run after 'at' should cause the 'at' instances
-to receive events.

+Contents of this package
+------------------------
+
+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.
+
+Directory structure
+-------------------
+
+The directories within this package are arranged as follows:
+
+ droute
+
+ Contains a framework for registering objects
+ with a D-Bus connection and for routing messages to
+ the implementing object.
+
+ Used by the ATK adaptor.
+
+ atk-adaptor
+
+ This directory contains code that bridges
+ the at-spi to the GTK+ toolkit, and which is
+ loaded at runtime by GTK+-based Gnome applications.
+ The 'bridge' automatically registers GTK+-2.0
+ applications with the accessibility registry,
+ and relays UI events from application to registry.
+ It is also responsible for servicing requests from
+ the registry to register handlers for specific event
+ types.
