But there is a condition. And the condition, of course, is the reason why we go to all this trouble, so that we could put the condition in. The condition says: Whenever you distribute anything that contains any piece of this program, that whole program must be distributed under these same terms, no more and no less. So you can change the program and distribute a modified version, but when you do, the people who get that from you must get the same freedom that you got from us. And not just for the parts of it &mdash; the excerpts that you copied from our program &mdash; but also for the other parts of that program that they got from you. The whole of that program has to be free software for them.
