Copyleft Notice from Wu Siu Yan
All material on my homepage may be freely reproduced, including computer programs, provided you agree with the "copy-left agreement" of Free Software Foundation, in essence, the agreement is,
You may freely copy, distribute, or sell the material or computer programs on my homepage provided you agree to (1) All webpages other than computer programs MAY NOT be altered. (2) If you modify the source code of a program, and when you sell or give your new code to others, you MUST supply him with the original code, so that he can form a more complete judgement. (3) When you sell or give programs ( or your modified version ) to others, you must give him the same right to "freely use, distribute, sell, or modify " the programs or your modified ones, as you have received. Item (3) is added because years ago, when Free Software Foundation gave programs to others freely, they modified the program, and patented the modified version for their own!
I do not mean to lay burdens to weary you. Should you still find the above difficult to comply, you may do in a way "right/fair/just in the sight of LORD" without communicating to me, as LORD is supreme judge of all.
Wu Siu Yan, 5th August, 2001.
