GPL

(General Public License) A free software license, originally written by Richard Stallman for the GNU project. The GPL is the most popular and well-known example of strong copyleft license that requires derived works to be available under the same copyleft. Under this philosophy, the GPL is said to grant the rights of the free software definition and uses copyleft to ensure the freedoms are preserved, even when the work is changed or added to. This is in distinction to permissive free software licences, of which the BSD licences are the standard examples.
