This software is dual-licensed.
- By default, this software is governed permissively under the terms of the ISC license; since all of the core (non-optional) modules are licensed as such. Also note that all third-party code, which has been adapted or adopted by these core modules, is also provided under similar permissive licensing terms (MIT, BSD, WOL, etc.). The specific license employed by each third-party code is stated clearly in the code comments at the point of its inclusion.
- Including and enabling certain optional modules, which are instead provided under the copy-left GNU GPLv2 license, will mean that the use of this software is instead governed by the GNU GPLv2 licencing terms.
Note that the license employed by each module is stated clearly in saf.h. For more information, refer to the license terms found at the top of each source and header file.
