-Short intro.
+Our framework still lacks of good way to create button and
+menu like objects. These objects are different than
+most other objects, since usually Vob doesn't know anything
+about events and events don't know anything about Vobs. 
+Now it's time to take care that vobs and events
+meet eachother in a way that selectable objects
+can be created.
+

 Changes
 =======
+
+Create a new abstract Vob which reacts to following events:
+
+    1) select down(pre selection, event pressed but no released), 
+    2) select up(no events, mostly this is the normal mode before events) and 
+    3) selection selected(post selection, event pressed and released).
+
+These three selections, `selection modes`, are represent with 
+three Vobs. Because of efficiency (reusing vobscene), 
+the select Vob is immutable and all three Vobs must be given 
+in constructor. The current `selection mode` is shown by one of the Vobs
+at the bottom and then placeable object is placed over it, i.e. text.
+The control of `selection mode` is done with second coordinate system.
+It is the only way to do it with immutable object.
