The tutorial has been created for the benefit of the community. All source code fragments inside are freely usable. You can download or print a copy for your own use, as you see fit, there are no restrictions. All I ask you is not to reproduce and distribute or publish it in its entirety, even if credited to me–link here instead, the site will not go away. This is not so much of a legal restriction, I simply want to make sure there are no forked and conflicting copies floating around the web.
