Documentation for supporting Spigot's Autorecovery scripts

Spigot has a line in it's config for autorecovery where you point it (usually at) start.sh and it'll just restart itself when it hangs. However, I'd love to have the documentation for what command needs to be put in it's place. I've tried using the one in /etc/init.d, and a few others, but none of the .sh scripts I've tried result in a successful autorecovery that reflects in the web admin.
