|============================================================================|   The Quote for the day is:

.. Any resemblance between the above views and those of my employer,
my terminal, or the view out my window are purely coincidental.  Any
resemblance between the above and my own views is non-deterministic.
The question of the existence of views in the absence of anyone to hold
them is left as an exercise for the reader.  The question of the
existence of the reader is left as an exercise for the second god
coefficient.  (A discussion of non-orthogonal, non-integral polytheism
is beyond the scope of this article.)
