GNU General Public License

The GNU General Public License is the software license used by Piga Software. The GNU General Public License was created and is maintained by the Free Software Foundation, and is a free software license that allows the redistribution, studying, copying and modifying of the program and its source code. The GNU General Public License is a "copyleft" license, meaning that it requires that every redistribution and modification of a released program fall under the same license, or a later version of the license, thereby preserving its status as free software. Many free software projects, such as the Linux kernel, Gambas or the The GIMP, use the GNU General Public License. Currently Piga Software uses version 3.0 of the GNU General Public License, and if ever a version 4.0 is published, it will be studied by the Piga staff and probably adopted.
