To quote Bryce Harrington from [1]: "MIT has released software under several slightly different licenses, including the old 'X11 License' or 'MIT License'. Some code under this license was in fact included in X.org's Xserver in the past. However, X.org now prefers the MIT Expat License as the standard (which, confusingly, is also referred to as the 'MIT License'). See http://cgit.freedesktop.org/xorg/xserver/tree/COPYING When Wayland started, it was Kristian Høgsberg's intent to license it compatibly with X.org. "I wanted Wayland to be usable (license-wise) whereever X was usable." But, the text of the older X11 License was taken for Wayland, rather than X11's current standard. This patch corrects this by swapping in the intended text." libinput is a fork of weston and thus inherited the original license intent and the license boilerplate itself. See this thread on wayland-devel here for a discussion: http://lists.freedesktop.org/archives/wayland-devel/2015-May/022301.html [1] http://lists.freedesktop.org/archives/wayland-devel/2015-June/022552.html Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@gmail.com> Acked-by: Jonas Ådahl <jadahl@gmail.com>
