Thanks everyone for the translation files but I think they don't follow the new Sourcemod 1.1 guideline for distributing language files ...
Distributing Language Files
As of SourceMod 1.1, there is a new preferred method of shipping translations. By default, the main translation file should only contain English phrases. Additional translations are made in separate files, under a folder named after the ISO language code in languages.cfg.

But I will take care of the modification
so don't bother.
Added an archive containing the translation files following the new 1.1 guideline. Can any sourcemod dev confirm this is what we should do ?
