The purpose of this script is to handle "STOP to quit" functionality for our SMS notification service we provide.

However, we're running into problems

I'm curious about the specific case of a csh script I have that batch runs a bunch of different build flavors and runs all night. If something occurs to me mid operation, I'd like to go in and add additional commands, or comment out un-executed ones.
