You may make, run and propagate covered works that you do not convey, without conditions so long as your license 
otherwise remains in force. You may convey covered works to others for the sole purpose of having them make 
modifications exclusively for you, or provide you with facilities for running those works, provided that you comply 
with the terms of this License in conveying all material for which you do not control copyright. Those thus making 
or running the covered works for you must do so exclusively on your behalf, under your direction and control, on 
terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
