Minecraft automatic starting, saving, and stopping

Here is a linux (Ubuntu) init script for starting and stopping (including running a /save-all to autosave) a pair of minecraft servers. Watch out for any line wrapping in the code below. Blogger has lousy support for code blocks. I've tried to keep it narrow but who knows. It's HTML. :)
