Update of /cvs-repository/Zope/lib/python/Products/PageTemplates
In directory cvs.zope.org:/tmp/cvs-serv6172/lib/python/Products/PageTemplates

Modified Files:
      Tag: Zope-2_6-i18n-branch
	TALES.py 
Added Files:
      Tag: Zope-2_6-i18n-branch
	GlobalTranslationService.py 
Log Message:
Added a hookable global translation service to PageTemplates, with tests.

A third-party product wishing to add a translation service simply has to
do:
    from Products.PageTemplates.GlobalTranslationService import \
         setGlobalTranslationService
    setGlobalTranslationService(mytranslationservice)
A translation service only needs one method, whose signature is:
    def translate(self, domain, msgid, mapping=None,
                  context=None, target_language=None)
It must return a translated string based on msgid and the domain, and
optionally the other arguments. The translated string can be Unicode.
