[Scilab-users] Licensing question

[Urban Simoncic]

Dear Scilab Community,

I have a question about Scilab licensing. I would like to develop an 
application based on Scilab (modified Scilab, GUI as a Scilab function 
and application functionality as a Scilab library and/or external module 
in C) and distribute everything (modified Scilab and my code) together 
as an application. What of that (modified Scilab, GUI as a Scilab 
function, my Scilab library and my external module in C) I have to 
distribute with sources? I am sure that I would have to open sources for 
modified Scilab and I don't care for that. I don't know for GUI and 
Scilab libraries (if necessary, I could open them). But I would expect 
that at least external modules can be distributed in binary form only 
(section 5.3.3. in license). However, I am not sure if they can be 
distributed together with the rest of the application that is under 
CeCILL, or I would have to distribute separately my external modules 
under my license and modified Scilab under CeCILL and expect that user 
will stack all that together?

Is it possible to get "official explantion" for such case, so that I can 
claim it, if I am sued later for violating the license?

Best Regards,
Urban
