In the east there is a shark which is larger than all other fish. It
changes into a bird whose winds are like clouds filling the sky. When this
bird moves across the land, it brings a message from Corporate Headquarters.
This message it drops into the midst of the program mers, like a seagull
making its mark upon the beach. Then the bird mounts on the wind and, with
the blue sky at its back, returns home.
The novice programmer stares in wonder at the bird, for he understands
it not. The average programmer dreads the coming of the bird, for he fears
its message. The master programmer continues to work at his terminal, for he
does not know that the bird has come and gone.
