Tornado-Babel adds i18n and l10n support to tornado with the help of babel and speaklater. It has builtin support for date formatting as well as a very simple and friendly interface to gettext translations.
Torando comes bundled with pretty basic locale support basic and does not offer support for merging translation catalogs and several other features most multi language applications require. The module also adds more date and number formatting helpers.
Tornado-Babel also includes a plugin for Babel to extract translatable strings from tornado templates.
