IANAL, but if I were asked to explain it I'd say that since that code
came from dbus-glib, that the code in that file is under the GPL/AFL
dual-license, and that the collective work of GVFS is LGPL, which is
why the LGPL copyright header is at the top of the file.

(And so you know, GVFS questions should be asked on the GVFS mailing list,
http://mail.gnome.org/mailman/listinfo/gvfs-list
But it's easy to mistake, the list is very new).

Hope that helps,
-A.Walton

Hi,

I am wonder what these two files are licensed under, the snipplet at the
end.

Is this LGPL or GPL or  Academic Free License version 2.1?
Thanks,

gio is lgpl because it is part of gtk+.  It is my understanding that
gvfs uses D-Bus and not gio so it it compatible because of that.

dbus-main is GPL/AFL dual licensed (always look at the COPYING file for
a full description of the license).  What dual licensing says is you can
use the file under either license but under copyright law you may not
modify the notice so if you use it under the AFL others can still use it
under the GPL.  You can however link any AFL compatible license and the
GPL will not apply to the external source.

We have been trying to re-license under MIT Permissive license to make
it easier for some licensing corner cases but hit a roadblock so that
may or may not happen.  If your apps is not compatible with the GPL or
AFL (such as GPL + exception licenses) you can add an AFL exception to
your licenses (provided you have the rights) and use D-Bus under the AFL
license.

Thanks John, and A.Walton!

I got concerned because it appeared under libdaemon_la_SOURCES
but as it turns up these is only used in the various gvfs-* commands after
nm the binaries.

Both your answers also helped me to understand quite a bit on dual
licensing :)
First time I see this in textual forms.

Thanks,
