I uploaded the files, I haven’t yet uploaded my small personal framework that accompanied it, but all you’re missing is some basic file handling class and a custom zlib wrapper, which is probably a little more complicated, but easily replaced.
The project is released under GPL, so if you do make any changes that end up seeing a public release, you must make sure to give them back to the project so that we can all benefit.
Either send me the code via e-mail, posting a comment or by becoming a part of the project.
Anyway, check it out:
