Hello!
I read that there is a license from GNU, the Free Documentation License, which is good to be applied to documents, like to the Help of FET.
I would like to apply this license to FET documentation. Is it enough if I add this phrase at the end of each document: "This document is licensed under GNU FDL"? But this is quite weird, because there are a lot of text documents - for instance, what should I add to the ChangeLog or README.
Also, I should add the license description, in a text file. Currently, there is a file, COPYING, describing the GNU GPL. Should I make 2 files: COPYING.GPL and COPYING.FDL, or LICENSE.GPL and LICENSE.FDL (like Qt has)?
As a second thought, I think I'll keep current state, only GPL license, and if someone else suggests something else, I'll try to improve. But I hope the GPL can clearly state that the documentation included in the FET package can be copied and modified.
