  *  Iterator.h
  *
  *  Base class for iterators. Extension writers that want to create traversable
- *  classes, should override this class and implement all pure virtual methods
- *  in it.
+ *  classes, should override the Php::Traversable base class. This base class
+ *  forces you to implement a getIterator() method that returns an instance of 
+ *  a Php::Iterator class.
+ * 
+ *  In this file you find the signature of the Php::Iterator class. It mostly has
+ *  pure virtual methods, which means that you should create a derived class
+ *  that implements all these methods.
