The Alchemist Simulator License

Explanation for humans

Alchemist adopts a GNU GPLv3 license with a permissive modification. Alchemist or parts of it can be used in commercial products and closed-source software components, as far as they are not mutated. Namely, the GPLv3 is extended with a linking/classpath exception, so it can be used freely as a library, but modified versions the software must instead be released with a GPLv3 compatible lincesing scheme. There is no requirement for the portion of the program calling Alchemist to be reverse-engineerable (the Alchemist license is more permissive than GNU LGPL). If you use the simulator for academic purposes, then you must refer the appropriate paper.

Compiling or linking this code statically or dynamically with other modules is making a combined work based on this code. Thus, the terms and conditions of the GNU General Public License cover the whole combination.

As a special exception, the copyright holders of this code give you permission to compile or link this code with independent modules to produce an executable, regardless of the license terms of these independent modules, and to copy and distribute the resulting executable under terms of your choice, provided that you also meet, for each independent module, the terms and conditions of the license of that module. An independent module is a module which is not derived from or based on this code. If you modify this code, you may extend this exception to your version of the code, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version.

Over and above the legal restrictions imposed by this license, if you use this software for an academic publication then you are obliged to provide proper attribution. This should be to the paper that describes this simulator, described in the CITATION file that comes with this software distribution.
