The internationalization framework allows you to easily mark strings for translation both in Python code and in your templates. It relies on the GNU gettext toolset to generate and manage message files. A message file is a plain text file that represents a language. It contains a part, or all, of the translation strings found in your application and their respective translations for a single language. Message files have the .po extension.
Once the translation is done, message files are compiled to offer rapid access to translated strings. The compiled translation files have the .mo extension.
