The GPL License, or General Public License, is a widely used free software license that allows users to freely use, modify, and distribute software. It ensures that any derivative works also remain free and open, promoting collaboration and sharing within the software community. This means that if someone modifies a program licensed under the GPL, they must also share their changes under the same license. The GPL License was created by the Free Software Foundation in 1989 and has since become one of the most popular licenses for open-source software. It aims to protect users' freedom to run, study, and share software, fostering an environment where innovation can thrive without restrictions.
