Yet another program dedicated to Sioe-Lin Kwik.
COLOUR WINDOW was created by Anders Bjerin, and is distributed as
public domain with NO RIGHTS RESERVED. That means that you can do
what ever you want with the program.
You may use COLOUR WINDOW in your own programs, commercial or not,
and do not even need to mention that you have used it. You may
alter the source code to fit your needs, and you may spread it to
anyone.
HAPPY PROGRAMMING,
Anders Bjerin
