UPDATE: Apparently this static-HTML version of the Seaside Book counts as a derivative work. I knew I forgot to do something after I put it together, and it was the most important step: notify the authors of the book and ask for permission (and an exception to the no-derivatives rule of their Creative Commons license). I have apologized in an email and stated that I will remove the files from the website and the links.
I also requested that the authors host a static version on their own site as an alternative because I don't see why Seaside's session management is needed for a tutorial. Hopefully this is done, but maybe it won't be. Ah well.
It's static now. The whole thing. All the images are there too, all the text is there and I changed the stylesheet so it takes up more of the screen space. The overview doesn't have links to all of the table of contents stuff but I'm tired right now.
In any case, it's good enough to start reading from. I did this mostly because I wanted a local copy but hey, it loads faster than the other dynamic version so why not let the rest of the Internet share in the speed?
