source: branches/gettext/upload.php @ 24311

Last change on this file since 24311 was 5021, checked in by nikrou, 15 years ago

Feature 1451 : localization with gettext
Use php-gettext (developpement version rev43, because of php5.3) as fallback
Use native language (english) instead of key for translation
Keep directory en_UK for english customization
Need some refactoring for plurals

Todo : managing plugins in the same way
