Since when did the GPL not cover non-code artifacts? The FSF's view at http://www.gnu.org/licenses/gpl-faq.en.html#GPLOtherThanSoftware http://www.gnu.org/licenses/gpl-faq.en.html#GPLOtherThanSoft...: "You can apply the GPL to any kind of work, as long as it is clear what constitutes the “source code” for the work. The GPL defines this as the preferred form of the work for making changes in it. However, for manuals and textbooks, or more generally any sort of work that is meant to teach a subject, we recommend using the GFDL rather than the GPL."
