Language definitions for Weblate

Weblate is libre software web-based continuous localization system, used by over 2500 libre projects and companies in more than 165 countries.

Language definitions used by Weblate and free to use by others.

Usage

The Python module can be installed from the PyPI:

pip install weblate-language-data

It contains several modules containing language definitions and Gettext translations for them (in a way that they would be discovered by Django when used as an Django application).
