Flask-BabelEx *DEPRECATION WARNING* All Flask-BabelEx features were merged into Flask-Babel and Flask-BabelEx package should no longer be used in your projects. Please migrate. Implements i18n and l10n support for Flask. This is fork of the official Flask-Babel extension with additional features: 1. It is possible to use multiple language catalogs in one Flask application; 2. Localization domains: your extension can package localization file(s) and use them if necessary; 3. Does not reload localizations for each request. Flask-BabelEx is API-compatible with Flask-Babel.
