AlterEgo is a Ruby implementation of the State pattern as described by  
the Gang  
of Four. It differs from other Ruby state machine libraries in that it  
focuses  
on providing polymorphic behavior based on object state. In effect, it  
makes it  
easy to give an object different personalities depending on the state it  
is in.
