+======
+README
+======
+
+Let's show how z3c.language.switch works:
+
+Imports and placeless setup:
+
+  >>> import zope.component
+  >>> from zope.app.testing import placelesssetup
+  >>> from z3c.language.switch import II18nLanguageSwitch
+  >>> from z3c.language.switch.testing import IContentObject
+  >>> from z3c.language.switch.testing import II18nContentObject
+  >>> from z3c.language.switch.testing import I18nContentObject
+  >>> from z3c.language.switch.testing import I18nContentObjectLanguageSwitch
+  >>> from z3c.language.switch.testing import ContentObject
+  >>> placelesssetup.setUp()
+
+Setup test object:
+
+  >>> en_title = u'en_title'
+  >>> obj = I18nContentObject(en_title)
+  >>> obj.title
+  u'en_title'
+
+Add additional languages:
+
+  >>> de_title = u'de_title'
+  >>> fr_title = u'fr_title'
+  >>> deObj = obj.addLanguage('de', de_title)
+  >>> frObj = obj.addLanguage('fr', fr_title)
+
+Switch default language:
+
+  >>> obj.title
+  u'en_title'
+
+  >>> obj.setDefaultLanguage('de')
+  >>> obj.title
+  u'de_title'
+
+Remove the 'en' language object:
+
+  >>> obj._data.keys()
+  ['de', 'en', 'fr']
+  >>> obj.removeLanguage('en')
+  >>> obj._data.keys()
+  ['de', 'fr']
+
+Remove default language object will end in a ValueError error:
+
+  >>> obj.removeLanguage('de')
+  Traceback (most recent call last):
+  ...
+  ValueError: cannot remove default language (de)
+
+Remove nonexistent language object will end in a ValueError error:
+
+  >>> obj.removeLanguage('undefined')
+  Traceback (most recent call last):
+  ...
+  ValueError: cannot remove nonexistent language (undefined)
+
+Set default language to a non existent language will end in a ValueError:
+
+  >>> obj.setDefaultLanguage('en')
+  Traceback (most recent call last):
+  ...
+  ValueError: cannot set nonexistent language (en) as default
+
+Access the language directly via the II18nLanguageSwitch adapter,
+first register the adapter for the I18nContentObject:
+
+  >>> zope.component.provideAdapter(I18nContentObjectLanguageSwitch,
+  ...     (II18nContentObject,), provides=II18nLanguageSwitch)
+
+The adapter is set to the default language in the init method:
+
+  >>> adapted = II18nLanguageSwitch(obj)
+  >>> adapted.title
+  u'de_title'
+
+Change the default language and access the title again, the title should not 
+switch to another language:
+
+  >>> obj.setDefaultLanguage('fr')
+  >>> adapted.title
+  u'de_title'
+
+Switch the language to 'fr'  via the adapter:
+
+  >>> adapted.setLanguage('fr')
+  >>> adapted.title
+  u'fr_title'
+
+Finally, clean up::
+
+  >>> placelesssetup.tearDown()
+
+
+AvailableLanguagesVocabulary
+----------------------------
+
+Use this vocabulary for get the available languages from the object 
+itself.
+
+  >>> from z3c.language.switch import vocabulary
+  >>> vocab = vocabulary.AvailableLanguagesVocabulary(obj)
+  >>> len(vocab._terms)
+  2
+
+  >>> vocab._terms[0].value
+  'de'
+  >>> vocab._terms[0].token
+  'de'
+  >>> vocab._terms[0].title
+  'de'
+  >>> vocab._terms[1].value
+  'fr'
+  >>> vocab._terms[1].token
+  'fr'
+  >>> vocab._terms[1].title
+  'fr'
