giftool was formerly developed by www.homepages.com (this domain has been bought by another company), which have discontinued to exist. The source-code is (c) by them, and restrictions apply for commercial use.

You can make GIFs interlaced, or non-interlaced and set transparency, and add comments.

GIFTool 2. Legal

Since the company stopped to exist, I do not know who owns the Copyright of it anymore. Since I consider the tool as must for every UNIX web-developer, I redistribute it here again freely. If this is a problem for anybody, let me know.
