A simple, elegant, concise helper module that converts quantities between measurement units.
For the moment only common distance units (metric + non-metric) are implemented, but the module can grow.
localization
Sozluk(meaning 'dictionary' in Turkish) is a localization library for Corona SDK (and probably LÖVE 2D).
Main difference of this library is that it uses Lua files to store localization data, instead of text or json files. This will let you easily update your games/apps over 50MB on Google Play without coping with patch files.
