-## Getters, setters, and Tweener
+## Animations
+
+Most objects that are animated are actors, and most properties used in animations
+are animatable, which means they can use implicit animations:
 
-Getters and setters should be used when you are dealing with an API that is
-designed around setting properties, like Tweener. If you want to animate an
-arbitrary property, create a getter and setter, and use Tweener to animate the
-property.
 ```javascript
-    var ANIMATION_TIME = 2000;
-
-    var MyClass = new Lang.Class({
-        Name: 'MyClass',
-
-        _init() {
-            this.actor = new St.BoxLayout();
-            this._position = 0;
-        },
-
-        get position() {

-        set position(value) {

+            mode: Clutter.AnimationMode.EASE_OUT_QUAD
+        });
+    }
+```
+
+The above is a convenience wrapper around the actual Clutter API, and should generally
+be preferred over the more verbose:
+
+```javascript
+    moveActor(actor, x, y) {
+        actor.save_easing_state();
+
+        actor.set_easing_duration(500);
+        actor.set_easing_mode(Clutter.AnimationMode.EASE_OUT_QUAD);
+        actor.set({
+            x,
+            y
+        });
+
+        actor.restore_easing_state();
+    }
+```
+
+There is a similar convenience API around Clutter.PropertyTransition to animate
+actor (or actor meta) properties that cannot use implicit animations:
+
+```javascript
+    desaturateActor(actor, desaturate) {
+        let factor = desaturate ? 1.0 : 0.0;
+        actor.ease_property('@effects.desaturate.factor', factor, {
+            duration: 500, // ms
+            mode: Clutter.AnimationMode.EASE_OUT_QUAD
+        });

+cldr2json
+=========
+
+This script converts Unicode CLDR android keyboard layouts to JSON usable by
+GNOME Shell.
+
+CLDR keyboard layouts can be found at
+<http://www.unicode.org/Public/cldr/latest/keyboards.zip>
+
+
+Usage
+=====
+
+    ./cldr2json <input file or directory> <output directory>
+
+example:
+
+    ./cldr2json cldr/keyboards/android/ json_layouts/
+
+
+Keyboard layout mapping
+=======================
+
+Unicode CLDR layout identifiers are language codes, while XKB layout
+identifiers are... something else. The mapping between the two currently uses
+heuristic based on the layout descriptions, in this order:
+
+- if the CLDR layout description matches an XKB layout description, chose its
+  XKB identifier
+- if one word of the CLDR layout description matches an XKB layout
+  description, chose its XKB identifier
+- if the CLDR layout description matches one word of an XKB layout description,
+  chose its XKB identifier
+
+That doesn't always work. For instance it fails for "en" language, that should
+match "us" XKB identifier. For such cases, there is a mapping in
+LOCALE_TO_XKB_OVERRIDES at the top of the script. If you discover a weird
+mapping of if you get a "failed to find XKB mapping for <locale>" warning then
+please consider adding an override there.
