+This directory contains the ATK library.
+
+For more information about ATK and accessibility in GNOME, see:
+ http://developer.gnome.org/projects/gap
+
+Dependencies
+============
+
+In order to get CVS atk installed on your system, you need to have
+the most recent CVS version of glib installed as well.
+
+Building
+========
+
+To compile a CVS version of atk on your system, you will need to take
+several steps to setup the tree for compilation.  You can do all these
+steps at once by running:
+
+        cvsroot/atk# ./autogen.sh
+  
+Basically this does the following for you:
+
+        cvsroot/atk# aclocal; automake; autoconf
+
+        The above commands create the "configure" script.  Now you
+        can run the configure script in cvsroot/atk to create all
+        the Makefiles.
+
+Before running autogen.sh or configure, make sure you have libtool
+in your path.
+
+Note that autogen.sh runs configure for you.  If you wish to pass
+options like --prefix=/usr to configure you can give those options
+to autogen.sh and they will be passed on to configure.
+
