I have a question regarding GFDL license under which all Yii documentation is published.
I used code from a couple of tutorials in the website that doesn’t allow any reuse or copy of the source code. And now I am having trouble figuring out if I am allowed to use code from tutorials. i.e. this code: http://www.yiiframework.com/wiki/93/using-the-jqueryslidemenu-plugin-with-cmenu/
If I am, then what should I say in comments. Wikipedia explanation of GFDL wasn’t very helpful. I hope you could clarify it.
