For a script this short, you could probably get away with just leaving
it here. However, I mean that in a "if you're really lazy, I suppose
you could" way. It will become easier to understand if you break it
up, and that is good for your future sanity. So it's not required, but
it definitely can't hurt, and if this script gets any larger you will
be glad you broke it up.
