All files released under the GPLv3 license [1] unless otherwise specified.  Ping me if you need this changed.

May contain some 3rd party libraries under their own (separate, open source) licenses.

Note that this software should be legal at least in the EU, 
as it is only software and therefore theoretically not subject to patents (see "What about patent licenses?" in [2]).

If it's not legal in your country, don't use it!
