let tomorrow=$today+1

I know some bash. I'm actually moving along quite well on this
particular project, though it looks like it's going to be a lot longer
then I origianally thought.
I know just a little bit about scripting in (t)csh.
I know *NO* perl. Or python. Or any other script language. I'm teaching
myself C, but this particular project can't wait that long. :)
