linking = The Aladdin Free Public License, abbreviated AFPL, is a license written by L. Peter Deutsch for his Ghostscript PostScript language interpreter. It was derived from the GNU General Public License, but differs on two key points:
* The source code must be included with any software distribution.
* The software may not be sold, including any fees involved with distribution.

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.

But I saw a number of companies bundling Ghostscript with commercial products while just barely complying with the letter of the GNU license, so I decided that I did not want to make Ghostscript as available for commercial distribution as it would be with the GNU license.] Recent versions of Ghostscript are not licensed under the AFPL.
