He +states that the code can be used freely for programs that are covered +by a "freeware" license. This probably includes both BSD style +licenses and the GPL. + +The code in "loader.asm" is a reimplementation of the uncompressor. It +has been written from scratch and is hereby placed under the +conditions of the GNU General Public License (GPL). The algorithm is +outlined in "algorithm.doc". + +Thus, there are no copyright problems with using this code, but there +still might be difficulties with software patents. These patents are +not legal in most parts of the world, but if you live in a country +that honors software patents then you should verify that using these +algorithms is legally permitted. Unless you are absolutely sure, that +there are no legal obstacles, you should use the code for educational +purposes only (this assumes that your educational institution is +exempted from patent laws). The author cannot be held responsible for +using the program code in violation of applicable local laws. + +If you are aware of patents that might affect the legality of using +the code in some parts of the world, please let me know. |
