Chameleon Translate Function Support
====================================
:func:`translationstring.ChameleonTranslate` is a function which
returns a callable suitable for use as the ``translate`` argument to
various ``PageTemplate*`` constructors.
.. code-block:: python
:linenos:
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
:class:`translationstring.TranslationString` instance) which returns a
``unicode`` object as a translation; usually the result of calling
:func:`translationstring.Translator`. ``translator`` may also
optionally be ``None``, in which case no translation is performed (the
``msgid`` or ``default`` value is returned untranslated).
