+"""*What is this pattern about?
+The Factory Method pattern can be used to create an interface for a
+method, leaving the implementation to the class that gets
+instantiated.
+
+*What does this example do?
+The code shows a way to localize words in two languages: English and
+Greek. "getLocalizer" is the factory method that constructs a
+localizer depending on the language chosen. The localizer object will
+be an instance from a different class according to the language
+localized. However, the main code does not have to worry about which
+localizer will be instantiated, since the method "get" will be called
+in the same way independently of the language.
+
+*Where can the pattern be used practically?
+The Factory Method can be seen in the popular web framework Django:
+http://django.wikispaces.asu.edu/*NEW*+Django+Design+Patterns For
+example, in a contact form of a web page, the subject and the message
+fields are created using the same form factory (CharField()), even
+though they have different implementations according to their
+purposes.
