hi there,

the project is to put together a beginners manual for knoppix

i want to modify a manual that was written for debian and released under GNU General Public License. its a bit strange because its not released under the free documentation license, just the software GNU General Public License. its at:

http://www.debian.org/doc/manuals/us...-guide.en.html

my question is about Progeny's copyright notice. if i do the modifications, how do i show that my work is based on progeny's original work?

its all a bit confusing, i looked at the GNU General Public License website with all their faq's but i am still left wondering.

can anyone show me a good example of how to legally modify a GNU General Public License document?
