Now that you've *asked*, I *suppose* we'll have to tell you The Secret. It's all part of the Conspiracy (but There Is No Conspiracy, of course.)
# Perl itself actually measures the computer's temperature,
# subtracts CPU temp, extrapolates the location of the closest
# window or door, catches the temp whenever it was last opened,
# and uses a heterogenous mean deteriorating sliding semi-
# automated average to compute the current temp +-0.0001 degrees.
# All part of DWIM, of course.

Don't tell anyone else, 'K?
