Well, there's this:
http://home.covad.net/~geoschmo/GenAiFileCreator.html
It doesn't do all the AI files, but it helps make the AI_general text file.
You can also get the file here so you can use it offline.
Download it here.
Don't know of a utility to make all the AI files, but it wouldn't suprise me if someone has and I just missed it.
