[Zope] i18n from a python script or external method

Hi I have installed and set up the PlacelessTranslationService product and it works correctly from Zope Page Templates. However, I have failed to get it to work from a python script or external python method. I have found several different methods via google however none of them work (ie none will translate a msg). Can someone please give me a valid method to do this for Zope 2.10 .3 or later. Thanks Adam
