Detailed Instructions: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Q: original question: Which software has the license of [University of Illinois/NCSA Open Source License]?
answer: clang, archon, llvm
answer type: Software.
auxiliary information: The University of Illinois/NCSA Open Source 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. It was formally certified as an open-source license during a March 28, 2002 board meeting of the Open Source Initiative. Source code under the NCSA license can be incorporated into proprietary products without the reciprocity requirements that copyleft free software licenses raise. The license is compatible with all versions of the GNU General Public License. Notable software using the license includes LLVM and Clang.
