4 The source code of CVC4 is open and available to students, researchers,
5 software companies, and everyone else to study, to modify, and to
6 redistribute original or modified versions; distribution is under the
7 terms of the modified BSD license. However, CVC4 can be configured (and
8 is, by default) to link against some GPLed libraries, and therefore the
9 use of these builds may be restricted in non-GPL-compatible projects.
10 See below for a discussion of CLN, GLPK, and Readline (the three GPLed
11 optional library dependences for CVC4), and how to ensure you have a
12 build that doesn't link against GPLed libraries.
