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