+ Third-Party Software
+-------------------------------------------------------------------------------
+
+The CVC4 source code includes third-party software which has its own copyright
+and licensing terms, as described below.
+
+The following file contains third-party software.
+
+ cmake/CodeCoverage.cmake
+
+The copyright and licensing information of this file is in its header.
+
+CVC4 incorporates MiniSat code (see src/prop/minisat and src/prop/bvminisat),
+excluded from the above copyright. See src/prop/minisat/LICENSE and
+src/prop/bvminisat/LICENSE for copyright and licensing information.
+
+CVC4 incorporates code from ANTLR3 (http://www.antlr3.org/), the files
+src/parser/bounded_token_buffer.h, src/parser/bounded_token_buffer.cpp, and
+src/parser/antlr_input_imports.cpp are excluded from the above copyright.
+See licenses/antlr3-LICENSE for copyright and licensing information.
+
+CVC4 by default links against The GNU Multiple Precision (GMP) Arithmetic
+Library, which is licensed under GNU LGPL v3. See the file
+licenses/lgpl-3.0.txt for a copy of that license. Note that according to the
+terms of the LGPL, both CVC4's source, and the combined work (CVC4 linked with
+GMP) may (and do) remain under the more permissive modified BSD license.
+
+The implementation of the floating point solver in CVC4 depends on symfpu
+(https://github.com/martin-cs/symfpu) written by Martin Brain.
+See https://raw.githubusercontent.com/martin-cs/symfpu/CVC4/LICENSE for
+copyright and licensing information.
+
+CVC4 optionally links against the following libraries:
+
+ ABC (https://bitbucket.org/alanmi/abc)
+ CaDiCaL (https://github.com/arminbiere/cadical)
+ CryptoMiniSat (https://github.com/msoos/cryptominisat)
+ LFSC checker (https://github.com/CVC4/LFSC)
+
+Linking CVC4 against these libraries does not affect the license terms of the
+CVC4 code. See the respective projects for copyright and licensing
+information.
+
+
+-------------------------------------------------------------------------------
+ OPTIONAL GPLv3 libraries
+-------------------------------------------------------------------------------
+
+Please be advised that the following libraries are covered under the GPLv3
+license. If you choose to link CVC4 against one of these libraries, the
+resulting combined work is also covered under the GPLv3. If you want to make
+sure you build a version of CVC4 that uses no GPLed libraries, configure CVC4
+with the "--no-gpl" option before building (which is the default). CVC4 can
+then be used in contexts where you want to use CVC4 under the terms of the
+(modified) BSD license. See licenses/gpl-3.0.txt for more information.
+
+CVC4 can be optionally configured to link against CLN, the Class Library for
+Numbers, available here:
+
+ http://www.ginac.de/CLN/
+
+CVC4 can be optionally configured to link against glpk-cut-log, a modified
+version of GLPK, the GNU Linear Programming Kit, available here:
+
+ https://github.com/timothy-king/glpk-cut-log
+
+CVC4 can be optionally configured to link against GNU Readline for improved
+text-editing support in interactive mode. GNU Readline is available here:
