The copyright and (lack of) warranty information most relevant to you is in the file COPYING that you got with your CVC4 source code, or received with any binary packaging of CVC4. The 1.3 release is covered by the following copyright and disclaimers: 

CVC4 is copyright (C) 2009, 2010, 2011, 2012, 2013 New York University
and The University of Iowa.  All rights reserved.

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.

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.
