The University of Illinois/NCSA Open Source License, or UIUC license, is a permissive free software license, based on the MIT/X11 license and the 3-clause BSD license. By combining parts of these two licenses, it attempts to be clearer and more concise than either.The license is the result of efforts by a University of Illinois committee set up in 2001. The intention was to create a new license standard for both NCSA and the worldwide software community in general.
