Now the GNU GPL is a copyleft license, and that means it says &ldquo;Yes, you're free to put this code into other things, but when you do, the entire program that you put things into you must release as free software under the same license. And you must make the source code available to users, and to inform them of their rights you must give them a copy of this license when they get the software.&rdquo;
