%description
    The program SNOW is used to conceal messages in ASCII text by
    appending whitespace to the end of lines. Because spaces and
    tabs are generally not visible in text viewers, the message is
    effectively hidden from casual observers. And if the built-in
    encryption is used, the message cannot be read even if it is
    detected. SNOW uses the ICE encryption algorithm.
