stego, short for Steganosaurus, converts ansforms any binary file into
nonsense text based on a dictionary either given explicitly or built on the
fly from a source document.  The output of stego is nonsense, but
statistically resembles text in the language of the dictionary supplied.
Although a human reader will instantly recognise it as gibberish,
statistical sampling employed by eavesdroppers to detect encrypted messages
may consider it to be unremarkable, especially if a relatively small amount
of such text appears within a larger document.
