Sometimes you might like to store all language files in your own central location, so that translators have one easy place to access all language files.

Put the above into the functions.php and add textdomain handling for those you want to centralize.

Most current plugins should include the option to store language files to the global WordPress language folder, but that is sometimes just not enough :) Its all about options ;)
