Express and the Node.js module i18n and the now lack of helpers

From the README at https://github.com/mashpie/i18n-node they show how to set it up with express templates but it uses helpers:

// register helpers for use in templates
app.helpers({
  __i: i18n.__,
  __n: i18n.__n
});

Well in Express 3.0 there are no helpers so how do I register the i18n module with the templates?

Thanks for any help!

helpers are now renamed to locals:

app.locals({
  __i: i18n.__,
  __n: i18n.__n
});
