translationstring.ChameleonTranslate is a function which returns a callable suitable for use as the translate argument to various PageTemplate* constructors.
from chameleon.zpt.template import PageTemplate
from translationstring import ChameleonTranslate
from translationstring import Translator
import gettext
translations = gettext.translations(...)
translator = Translator(translations)
translate = ChameleonTranslate(translate)
pt = PageTemplate('<html></html>', translate=translate)The translator provided should be a callable which accepts a single argument translation_string ( a translationstring.TranslationString instance) which returns a unicode object as a translation; usually the result of calling translationstring.Translator. translator may also optionally be None, in which case no translation is performed (the msgid or default value is returned untranslated).
