Could somebody please have a quick look at these three licences? http://www.linuxdoc.org/COPYRIGHT.html http://www.linuxdoc.org/LDP-COPYRIGHT.html http://www.linuxdoc.org/HOWTO/XWindow-User-HOWTO-1.html#ss1.5 I believe that the first and third are simple DFSG-free copyrights, while the second is not (it requires modified versions to be approved by the author before distribution). Can somebody please confirm this? Thanks, -- Colin Watson [cjwatson@flatline.org.uk]
