Anyone can use Gifsicle however they wish; the license applies only to those who plan to copy, distribute, or alter its code. If you use Gifsicle for an organizational or commercial Web site, I would appreciate a link to the Gifsicle home page on any 'About This Server' page, but it's not required. This code, with the exception of the GIF compression code in gifwrite.c, is distributed under the GNU General Public License, Version 2, or, at your discretion, any later version. The GNU General Public License is available via the Web at The following alternative license may be used at your discretion. Permission is granted to copy, distribute, or alter gifsicle, whole or in part, as long as source code copyright notices are kept intact, with the following restrictions. 1. Unisys Corp. holds a patent on the Lempel-Ziv-Welch compression algorithm used by GIF images. When this first became an issue several years ago, Unisys stated that programs available at no cost to the user, like Gifsicle, could use LZW compression in the context of GIF images without obtaining a license. If you plan to distribute GIF writing code in a shareware or commercial product, you will need to worry about obtaining a license. (Many people believe that LZW decompression is not covered by the Unisys patent, so GIF reading code is probably all right.) 2. Developers or distributors who plan to use Gifsicle code, whole or in part, in a product whose source code will not be made available to the end user -- more precisely, in a context which would violate the GPL -- MUST contact the author and obtain permission before doing so. Please see /usr/share/common-licenses/GPL-2 for the full license. /* gifwrite.c - Functions to write GIFs.
