	We had a really suspicious lecturer in college who used to take the printouts
which we had handed in as assignments and hold them up to the light in batches,
looking for programs which were the same.

	He obviously didn't realize that the Pascal (well it was designed as a
teaching language!) `prettier' which we had available allowed you to customize
the indentation etc., though we cottoned on pretty quickly. A global replace on
a few variable names also defeated his system.
