Shhh, don't tell anyone but I've made a secret post. It's a simple script to look up language codes, but it's 1100 lines long. The script is one simple grep command, the other 1100 lines are just languages and codes.
I made the post date Jan 1 2009 so it would go straight to the archive and not take up the front page. It can be found here.
It may be useful to anyone running my iPhone language deleting script who runs across an unknown language code.
