IANAL either, but I don't think that parsing the output of a program creates a derivative-base relationship... > Indeed, the forementioned file > says, a program would be a derivate in the authors > interpretation of the GPL, if it > > """ > o Executes Nmap and parses the results (as opposed to typical shell or > execution-menu apps, which simply display raw Nmap output and so are > not derivative works.)

Even the FSF's interpretation (which stretches the definition of derivative work quite a bit, in the attempt to defend the copyleft mechanism of the GNU GPL) seems to assert that there's no derivation going on, when the two programs "communicate at arms length" [1]. [1] http://www.gnu.org/licenses/gpl-faq.html#GPLInProprietarySystem I would say that two programs communicate "at arms length", when one executes the other and parses its output... Let's anyway wait for the opinion of other debian-legal regulars. -- http://www.inventati.org/frx/frx-gpg-key-transition-2010.txt New GnuPG key, see the transition document! .....................................................
