many thanks for your work! We are using both of your classes (gif-encoder & gif-decoder) since three years now, in a so called third-party-module. Now we want to embedd this into the core code base of an open source project (https://processwire.com/) and faces the problem, that there are no open source compatible licences bundled with your libraries. Would you mind to add, for example the MIT or LGPL to them, in addition to "Freeware"?
And don't ask me why "Freeware" isn't appropriate or enough to allow the include, I'm not a lawyer. I'm only got told that this is needed to be on the safe side for open source projects. :-/
