What is the GNU GPLv2?¶

The GNU General Public License version 2 (GNU GPLv2 or simply GPLv2) is a widely-used free software license, originally written by Richard Stallman for the GNU movement. The GPLv2 is an example of a powerful copyleft license that requires derivative works to be released to the public under the same license. You can have a look at the full GPLv2 text or you can learn more on Wikipedia.
