What's also likely to occur is that someone may be working
on your script after you (e.g. adding functionality) and has to
remember to turn on the -T switch again, which (s)he may not
always remember to do, Thus rendering your "insurance"
null & void :)
While this may be true in most enviornments, your response
has pricked the nagging sys admin in me to say, "NO production
script should EVER be modified. Maintianing the
development->(Readiness if you can afford it)->Production cycle
is key to stable rapid deployment."
