| | Conditions to distribute Ghostscript in a commercial context (Site not responding. Last check: 2007-11-07) |
 | | Some versions of Ghostscript are distributed freely under the name AFPL Ghostscript or (for older versions) Aladdin Ghostscript; these versions are always distributed with a license, called the Aladdin Free Public License (also known as the AFPL), which permits AFPL Ghostscript to be redistributed freely under certain conditions. |
 | | Older versions of Ghostscript are distributed with a license called the GNU General Public License (also known as the "GNU License", the "GPL", or "copyleft"), which allowed distribution with commercial products under certain conditions. |
 | | One implication of this is that the GNU Ghostscript documentation must specify all properties of GNU Ghostscript on which the application relies; for example, if GNU Ghostscript has been modified by the addition of command line switches or language elements such as new operators, the documentation must describe any such additions that the application uses. |
