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

 Certain builds of CVC4 link against a GPLed library, CLN, the Class Library
 for Numbers, available here:
 
   http://www.ginac.de/CLN/
 
 Please be advised that as this class library is covered under the GPLv3, if
 you choose to use the combined work, "CVC4+CLN," by building CVC4 with CLN,
 then it is also covered under the GPLv3.  If you want to make sure you build
 a version of CVC4 that uses libgmp, the GNU Multiple Precision Arithmetic
 Library, configure CVC4 with "--with-gmp" before building (though that is the
 default).  It can then be used in contexts where you want to license CVC4
 under the (modified) BSD license.
 
 Certain builds of CVC4 link against a GPLed library, GLPK, the GNU Linear
 Programming Kit, available here:
 
   http://www.gnu.org/software/glpk/
 
 Please be advised that as this library is covered under the GPLv3, if
 you choose to use the combined work, "CVC4+GLPK," by building CVC4 with
 GLPK, then it is also covered under the GPLv3.  If you want to make sure
 you build a version of CVC4 that does not use GLPK, configure CVC4 with
 "--without-glpk" before building (though that is the default).  It can
 then be used in contexts where you want to license CVC4 under the
 (modified) BSD license.
