Libraries Licenses

---

This page lists all licenses of code SUMO depends on directly for compiling. There may be secondary references (like the C++ standard library or a particular OpenGL implementation) which are not mentioned here except for the cases where we deliver binaries for that code.

Code in the repository#

All the code which can be found under <SUMO>/src and <SUMO>/tools except for <SUMO>/src/foreign and <SUMO>/tools/contributed is since 03.10.2017 (revision 26300) licensed under EPL V2. All earlier versions were licensed under GPL V3+. The code in <SUMO>/src/foreign and <SUMO>/tools/contributed should have separate license files but we strive to list them here as well:
