GPLCode

GPLCode is a term that refers to software licensed under the GNU General Public License (GPL). The GPL is a free software license that guarantees end users the freedom to run, study, share, and modify the software. It is a copyleft license, meaning that any derivative works must also be licensed under the GPL.

The GPL is one of the most widely used free software licenses in the world. It is used by a large number of software projects, including the Linux kernel, the GNU operating system, and the GCC compiler. The GPL is also used by a number of commercial software products, as well as by many open-source projects.

The GPL is designed to promote the development and use of free software. It does this by ensuring that software licensed under the GPL is always free, and that users are always free to modify and share the software. The GPL also helps to ensure that software licensed under the GPL is always compatible with other free software.

There are two main versions of the GPL: the GPLv2 and the GPLv3. The GPLv2 was released in 1991 and is still used by many software projects. The GPLv3 was released in 2007 and includes a number of improvements over the GPLv2, including better support for international users and a more explicit statement of patent rights.

While the GPL is a powerful tool for promoting free software, it can also be a source of controversy. Some people argue that the GPL is too restrictive and that it hinders the development of commercial software. Others argue that the GPL is too permissive and that it does not do enough to protect the rights of free software users.
