4 CVC4 is open-source; distribution is under the terms of the modified BSD
5 license. However, certain builds of CVC4 link against GPLed libraries,
6 and therefore the use of these builds is restricted in non-open-source
7 projects. See below for a discussion of CLN and how to ensure you have
8 a build that doesn't link against GPLed libraries.

235 Certain builds of CVC4 link against a GPLed library, CLN, the Class Library
236 for Numbers, available here:
238 http://www.ginac.de/CLN/
240 Please be advised that as this class library is covered under the GPLv3, if
241 you choose to use the combined work, "CVC4+CLN," by building CVC4 with CLN,
242 then it is also covered under the GPLv3. If you want to make sure you build
243 a version of CVC4 that uses libgmp, the GNU Multiple Precision Arithmetic
244 Library, configure CVC4 with "--with-gmp" before building (though that is the
245 default). It can then be used in contexts where you want to license CVC4
246 under the (modified) BSD license.
