I translated the magento. I want to create a language pack and upload to Magento. I do not know how to create packages. I tried to create a pack with "Create Extension Packag" in admin panel. I completed the all fields.
New Extension->Contents Iset Path:
/magento/magento/app/locale/my_file/ Type: Res.Dir.
In "conncect" folder I see only tgz file with xml inside without language pack.
