The Aladdin Free Public License, abbreviated AFPL, is a license written by L. Peter Deutsch for his Ghostscript PostScript language interpreter.
The license was derived from the GNU General Public License, but differs on two key points: Deutsch chose to include a commercial restriction in the AFPL based on his observation of people including Ghostscript in commercial products without full license compliance.
[2] Recent versions of Ghostscript are not licensed under the AFPL.
[3] Despite the name, the Free Software Foundation does not consider the AFPL a free software license,[1] neither the OSI consider it an open-source license, nor does it fall under the Copyfree Standard definition.
[4] The AFPL can be considered a source-available license.
