Code in johnny is under reduced mit license. It seems to be compatible with whatever there could be. Images are... I do not know license. README.icons says: Originally created: 10 Nov 2009 Icon creators: see LICENSES file Archive Creator: Jeff Israel License url: http://openiconlibrary.sourceforge.net/LICENSES.html ... The icons in this package are under various free/open licenses such as GPL, Creative Commons, etc. All sources with their respective licenses are documented in the LICENSES file, as well as in their metadata. License url: http://openiconlibrary.sourceforge.net/LICENSES.html Images do not have meta information. So it is hard to determine what exact license certain image is subject to. By the way if we package johnny as .deb or .rpm then should we use images from respective packages on system? Or is it ok to dupe images? Though it is related only to src packages. I guess I need to craft src .deb to build right .deb binary package. Qt is available under LGPL 2.1 with exception, GPL 3.0 or commercial license. For binary distribution GPL 3.0 seems ok for us: we could refer to sources in original place not providing them directly (e.g. qt's site if we build against sources from there, page at packages.debian.org if we build on debian). How should I notice it? GPL-3 point 5.d says: d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. It does not seem to affect me because qt does not seem to have interactive interface. So I could postpone "about" screen and do not write there about qt at all. Currently I am lost with all these points. I do not know what I should do with it and should I do something at all. Any tips? Thanks! -- Regards, Aleksey Cherepanov
