AppleScript for auto-shutdown?

I'm looking for a script that will shut down the computer after a program has closed. Thanks in advance.

can I ask what do you need it for? I imagine it would have to be some sort of a custom listener that would scan running processes and do a shutdown when the application isn't one of them .. no idea though if applescript has process monitoring capabilities

you could try a bash script though

All in all, you will probably have to write it yourself
