The current modules are made for one language and one wiki. Small wikis do not have Lua-coders to translate them and can not enjoy them.
So I wrote a module able to translate them and more ...
To convert a module into a central module, you have to add some tables of arguments ... and replace the texts with their translation keys and their arguments.
For a new language, only add translations, in Module:Example/I18N, without any configuration.
