[Inkscape-devel] tutorial copyright question

Hi, I'm going to write a tutorial for the calligraphy tool I implemented in Karbon, given that the tutorial of Inkscape is done very well and the tool is very similar I thought it would be silly to rewrite it from scratch. It isn't too clear under which license the tutorial is licensed so some clarification

would be greatly appreciated. The xml file generating the tutorial contains the line:

<!-- Copyright (C) 2004-6 bulia byak, buliabyak@...859... and josh andler, scislac@...1050...>

The parent directory also contains a COPYING file with the GPL, my best guess is thus that that's the license of the tutorial, but I would like a confirmation.

Thanks! - fela
