+Changes for 1.7.0:
+
+* New feature: death tests are supported on OpenBSD and in iOS
+  simulator now.
+* New feature: Google Test now implements a protocol to allow
+  a test runner to detect that a test program has exited
+  prematurely and report it as a failure (before it would be
+  falsely reported as a success if the exit code is 0).
+* New feature: Test::RecordProperty() can now be used outside of the
+  lifespan of a test method, in which case it will be attributed to
+  the current test case or the test program in the XML report.
+* New feature (potentially breaking): --gtest_list_tests now prints
+  the type parameters and value parameters for each test.
+* Improvement: char pointers and char arrays are now escaped properly
+  in failure messages.
+* Improvement: failure summary in XML reports now includes file and
+  line information.
+* Improvement: the <testsuites> XML element now has a timestamp attribute.
+* Improvement: When --gtest_filter is specified, XML report now doesn't
+  contain information about tests that are filtered out.
+* Fixed the bug where long --gtest_filter flag values are truncated in
+  death tests.
+* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
+  function instead of a macro in order to work better with Clang.
+* Compatibility fixes with C++ 11 and various platforms.
+* Bug/warning fixes.
+
+Changes for 1.6.0:
+
+* New feature: ADD_FAILURE_AT() for reporting a test failure at the
+  given source location -- useful for writing testing utilities.
+* New feature: the universal value printer is moved from Google Mock
+  to Google Test.
+* New feature: type parameters and value parameters are reported in
+  the XML report now.
+* A gtest_disable_pthreads CMake option.
+* Colored output works in GNU Screen sessions now.
+* Parameters of value-parameterized tests are now printed in the
+  textual output.
+* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
+  now correctly reported.
+* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
+  ostream.
+* More complete handling of exceptions.
+* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
+  name is already used by another library.
+* --gtest_catch_exceptions is now true by default, allowing a test
+  program to continue after an exception is thrown.
+* Value-parameterized test fixtures can now derive from Test and
+  WithParamInterface<T> separately, easing conversion of legacy tests.
+* Death test messages are clearly marked to make them more
+  distinguishable from other messages.
+* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
+  PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
+  IBM XL C++ (Visual Age C++), and C++0x.
+* Bug fixes and implementation clean-ups.
+* Potentially incompatible changes: disables the harmful 'make install'
+  command in autotools.
+
+Changes for 1.5.0:
+
+ * New feature: assertions can be safely called in multiple threads
+   where the pthreads library is available.
+ * New feature: predicates used inside EXPECT_TRUE() and friends
+   can now generate custom failure messages.
+ * New feature: Google Test can now be compiled as a DLL.
+ * New feature: fused source files are included.
+ * New feature: prints help when encountering unrecognized Google Test flags.
+ * Experimental feature: CMake build script (requires CMake 2.6.4+).
+ * Experimental feature: the Pump script for meta programming.
+ * double values streamed to an assertion are printed with enough precision
+   to differentiate any two different values.
+ * Google Test now works on Solaris and AIX.
+ * Build and test script improvements.
+ * Bug fixes and implementation clean-ups.
+
+ Potentially breaking changes:
+
+ * Stopped supporting VC++ 7.1 with exceptions disabled.
+ * Dropped support for 'make install'.
+
+Changes for 1.4.0:
+
+ * New feature: the event listener API
+ * New feature: test shuffling
+ * New feature: the XML report format is closer to junitreport and can
+   be parsed by Hudson now.
+ * New feature: when a test runs under Visual Studio, its failures are
+   integrated in the IDE.
+ * New feature: /MD(d) versions of VC++ projects.
+ * New feature: elapsed time for the tests is printed by default.
+ * New feature: comes with a TR1 tuple implementation such that Boost
+   is no longer needed for Combine().
+ * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
+ * New feature: the Xcode project can now produce static gtest
+   libraries in addition to a framework.

+ * New feature: support for distributing test functions to multiple
+   machines (requires support from the test runner).
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.2.1:
+
+ * Compatibility fixes for Linux IA-64 and IBM z/OS.
+ * Added support for using Boost and other TR1 implementations.
+ * Changes to the build scripts to support upcoming release of Google C++
+   Mocking Framework.

+Google C++ Testing Framework
+============================
+
+http://code.google.com/p/googletest/
+
+Overview
+--------
+
+Google's framework for writing C++ tests on a variety of platforms
+(Linux, Mac OS X, Windows, Windows CE, Symbian, etc).  Based on the
+xUnit architecture.  Supports automatic test discovery, a rich set of
+assertions, user-defined assertions, death tests, fatal and non-fatal
+failures, various options for running the tests, and XML test report
+generation.
+
+Please see the project page above for more information as well as the
+mailing list for questions, discussions, and development.  There is
+also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
+join us!
+
+Requirements for End Users
+--------------------------
+
+Google Test is designed to have fairly minimal requirements to build
+and use with your projects, but there are some.  Currently, we support
+Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
+effort to support other platforms (e.g. Solaris, AIX, and z/OS).
+However, since core members of the Google Test project have no access
+to these platforms, Google Test may have outstanding issues there.  If
+you notice any problems on your platform, please notify
+googletestframework@googlegroups.com.  Patches for fixing them are
+even more welcome!
+
+### Linux Requirements ###
+
+These are the base requirements to build and use Google Test from a source
+package (as described below):
+  * GNU-compatible Make or gmake
+  * POSIX-standard shell
+  * POSIX(-2) Regular Expressions (regex.h)
+  * A C++98-standard-compliant compiler
+
+### Windows Requirements ###
+
+  * Microsoft Visual C++ 7.1 or newer
+
+### Cygwin Requirements ###
+
+  * Cygwin 1.5.25-14 or newer
+
+### Mac OS X Requirements ###
+
+  * Mac OS X 10.4 Tiger or newer
+  * Developer Tools Installed
+
+Also, you'll need CMake 2.6.4 or higher if you want to build the
+samples using the provided CMake script, regardless of the platform.
+
+Requirements for Contributors
+-----------------------------
+
+We welcome patches.  If you plan to contribute a patch, you need to
+build Google Test and its own tests from an SVN checkout (described
+below), which has further requirements:
+
+  * Python version 2.3 or newer (for running some of the tests and
+    re-generating certain source files from templates)
+  * CMake 2.6.4 or newer
+
+Getting the Source
+------------------
+
+There are two primary ways of getting Google Test's source code: you
+can download a stable source release in your preferred archive format,
+or directly check out the source from our Subversion (SVN) repository.
+The SVN checkout requires a few extra steps and some extra software
+packages on your system, but lets you track the latest development and
+make patches much more easily, so we highly encourage it.
+
+### Source Package ###
+
+Google Test is released in versioned source packages which can be
+downloaded from the download page [1].  Several different archive
+formats are provided, but the only difference is the tools used to
+manipulate them, and the size of the resulting file.  Download
+whichever you are most comfortable with.
+
+  [1] http://code.google.com/p/googletest/downloads/list
+
+Once the package is downloaded, expand it using whichever tools you
+prefer for that type.  This will result in a new directory with the
+name "gtest-X.Y.Z" which contains all of the source code.  Here are
+some examples on Linux:
+
+  tar -xvzf gtest-X.Y.Z.tar.gz
+  tar -xvjf gtest-X.Y.Z.tar.bz2
+  unzip gtest-X.Y.Z.zip
+
+### SVN Checkout ###
+
+To check out the main branch (also known as the "trunk") of Google
+Test, run the following Subversion command:
+
+  svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
+
+Setting up the Build
+--------------------
+
+To build Google Test and your tests that use it, you need to tell your
+build system where to find its headers and source files.  The exact
+way to do it depends on which build system you use, and is usually
+straightforward.
+
+### Generic Build Instructions ###
+
+Suppose you put Google Test in directory ${GTEST_DIR}.  To build it,
+create a library build target (or a project as called by Visual Studio
+and Xcode) to compile
+
+  ${GTEST_DIR}/src/gtest-all.cc
+
+with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR}
+in the normal header search path.  Assuming a Linux-like system and gcc,
+something like the following will do:
+
+  g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+      -pthread -c ${GTEST_DIR}/src/gtest-all.cc
+  ar -rv libgtest.a gtest-all.o
+
+(We need -pthread as Google Test uses threads.)
+
+Next, you should compile your test source file with
+${GTEST_DIR}/include in the system header search path, and link it
+with gtest and any other necessary libraries:
+
+  g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
+      -o your_test
+
+As an example, the make/ directory contains a Makefile that you can
+use to build Google Test on systems where GNU make is available
+(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
+Test's own tests.  Instead, it just builds the Google Test library and
+a sample test.  You can use it as a starting point for your own build
+script.
+
+If the default settings are correct for your environment, the
+following commands should succeed:
+
+  cd ${GTEST_DIR}/make
+  make
+  ./sample1_unittest
+
+If you see errors, try to tweak the contents of make/Makefile to make
+them go away.  There are instructions in make/Makefile on how to do
+it.
+
+### Using CMake ###
+
+Google Test comes with a CMake build script (CMakeLists.txt) that can
+be used on a wide range of platforms ("C" stands for cross-platform.).
+If you don't have CMake installed already, you can download it for
+free from http://www.cmake.org/.
+
+CMake works by generating native makefiles or build projects that can
+be used in the compiler environment of your choice.  The typical
+workflow starts with:
+
+  mkdir mybuild       # Create a directory to hold the build output.
+  cd mybuild
+  cmake ${GTEST_DIR}  # Generate native build scripts.
+
+If you want to build Google Test's samples, you should replace the
+last command with
+
+  cmake -Dgtest_build_samples=ON ${GTEST_DIR}
+
+If you are on a *nix system, you should now see a Makefile in the
+current directory.  Just type 'make' to build gtest.
+
+If you use Windows and have Visual Studio installed, a gtest.sln file
+and several .vcproj files will be created.  You can then build them
+using Visual Studio.
+
+On Mac OS X with Xcode installed, a .xcodeproj file will be generated.
+
+### Legacy Build Scripts ###
+
+Before settling on CMake, we have been providing hand-maintained build
+projects/scripts for Visual Studio, Xcode, and Autotools.  While we
+continue to provide them for convenience, they are not actively
+maintained any more.  We highly recommend that you follow the
+instructions in the previous two sections to integrate Google Test
+with your existing build system.
+
+If you still need to use the legacy build scripts, here's how:
+
+The msvc\ folder contains two solutions with Visual C++ projects.
+Open the gtest.sln or gtest-md.sln file using Visual Studio, and you
+are ready to build Google Test the same way you build any Visual
+Studio project.  Files that have names ending with -md use DLL
+versions of Microsoft runtime libraries (the /MD or the /MDd compiler
+option).  Files without that suffix use static versions of the runtime
+libraries (the /MT or the /MTd option).  Please note that one must use
+the same option to compile both gtest and the test code.  If you use
+Visual Studio 2005 or above, we recommend the -md version as /MD is
+the default for new projects in these versions of Visual Studio.
+
+On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using
+Xcode.  Build the "gtest" target.  The universal binary framework will
+end up in your selected build directory (selected in the Xcode
+"Preferences..." -> "Building" pane and defaults to xcode/build).
+Alternatively, at the command line, enter:
+
+  xcodebuild
+
+This will build the "Release" configuration of gtest.framework in your
+default build location.  See the "xcodebuild" man page for more
+information about building different configurations and building in
+different locations.
+
+If you wish to use the Google Test Xcode project with Xcode 4.x and
+above, you need to either:
+ * update the SDK configuration options in xcode/Config/General.xconfig.
+   Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If
+   you choose this route you lose the ability to target earlier versions
+   of MacOS X.
+ * Install an SDK for an earlier version. This doesn't appear to be
+   supported by Apple, but has been reported to work
+   (http://stackoverflow.com/questions/5378518).
+
+Tweaking Google Test
+--------------------
+
+Google Test can be used in diverse environments.  The default
+configuration may not work (or may not work well) out of the box in
+some environments.  However, you can easily tweak Google Test by
+defining control macros on the compiler command line.  Generally,
+these macros are named like GTEST_XYZ and you define them to either 1
+or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below.  For a complete list,
+see file include/gtest/internal/gtest-port.h.
+
+### Choosing a TR1 Tuple Library ###
+
+Some Google Test features require the C++ Technical Report 1 (TR1)
+tuple library, which is not yet available with all compilers.  The
+good news is that Google Test implements a subset of TR1 tuple that's
+enough for its own need, and will automatically use this when the
+compiler doesn't provide TR1 tuple.
+
+Usually you don't need to care about which tuple library Google Test
+uses.  However, if your project already uses TR1 tuple, you need to
+tell Google Test to use the same TR1 tuple library the rest of your
+project uses, or the two tuple implementations will clash.  To do
+that, add
+
+  -DGTEST_USE_OWN_TR1_TUPLE=0
+
+to the compiler flags while compiling Google Test and your tests.  If
+you want to force Google Test to use its own tuple library, just add
+
+  -DGTEST_USE_OWN_TR1_TUPLE=1
+
+to the compiler flags instead.
+
+If you don't want Google Test to use tuple at all, add
+
+  -DGTEST_HAS_TR1_TUPLE=0
+
+and all features using tuple will be disabled.
+
+### Multi-threaded Tests ###
+
+Google Test is thread-safe where the pthread library is available.
+After #include "gtest/gtest.h", you can check the GTEST_IS_THREADSAFE
+macro to see whether this is the case (yes if the macro is #defined to
+1, no if it's undefined.).
+
+If Google Test doesn't correctly detect whether pthread is available
+in your environment, you can force it with
+
+  -DGTEST_HAS_PTHREAD=1
+
+or
+
+  -DGTEST_HAS_PTHREAD=0
+
+When Google Test uses pthread, you may need to add flags to your
+compiler and/or linker to select the pthread library, or you'll get
+link errors.  If you use the CMake script or the deprecated Autotools
+script, this is taken care of for you.  If you use your own build
+script, you'll need to read your compiler and linker's manual to
+figure out what flags to add.
+
+### As a Shared Library (DLL) ###
+
+Google Test is compact, so most users can build and link it as a
+static library for the simplicity.  You can choose to use Google Test
+as a shared library (known as a DLL on Windows) if you prefer.
+
+To compile *gtest* as a shared library, add
+
+  -DGTEST_CREATE_SHARED_LIBRARY=1
+
+to the compiler flags.  You'll also need to tell the linker to produce
+a shared library instead - consult your linker's manual for how to do
+it.
+
+To compile your *tests* that use the gtest shared library, add
+
+  -DGTEST_LINKED_AS_SHARED_LIBRARY=1
+
+to the compiler flags.
+
+Note: while the above steps aren't technically necessary today when
+using some compilers (e.g. GCC), they may become necessary in the
+future, if we decide to improve the speed of loading the library (see
+http://gcc.gnu.org/wiki/Visibility for details).  Therefore you are
+recommended to always add the above flags when using Google Test as a
+shared library.  Otherwise a future release of Google Test may break
+your build script.
+
+### Avoiding Macro Name Clashes ###
+
+In C++, macros don't obey namespaces.  Therefore two libraries that
+both define a macro of the same name will clash if you #include both
+definitions.  In case a Google Test macro clashes with another
+library, you can force Google Test to rename its macro to avoid the
+conflict.
+
+Specifically, if both Google Test and some other code define macro
+FOO, you can add
+
+  -DGTEST_DONT_DEFINE_FOO=1
+
+to the compiler flags to tell Google Test to change the macro's name
+from FOO to GTEST_FOO.  Currently FOO can be FAIL, SUCCEED, or TEST.
+For example, with -DGTEST_DONT_DEFINE_TEST=1, you'll need to write
+
+  GTEST_TEST(SomeTest, DoesThis) { ... }
+
+instead of
+
+  TEST(SomeTest, DoesThis) { ... }
+
+in order to define a test.
+
+Upgrating from an Earlier Version
+---------------------------------
+
+We strive to keep Google Test releases backward compatible.
+Sometimes, though, we have to make some breaking changes for the
+users' long-term benefits.  This section describes what you'll need to
+do if you are upgrading from an earlier version of Google Test.
+
+### Upgrading from 1.3.0 or Earlier ###
+
+You may need to explicitly enable or disable Google Test's own TR1
+tuple library.  See the instructions in section "Choosing a TR1 Tuple
+Library".
+
+### Upgrading from 1.4.0 or Earlier ###
+
+The Autotools build script (configure + make) is no longer officially
+supportted.  You are encouraged to migrate to your own build system or
+use CMake.  If you still need to use Autotools, you can find
+instructions in the README file from Google Test 1.4.0.
+
+On platforms where the pthread library is available, Google Test uses
+it in order to be thread-safe.  See the "Multi-threaded Tests" section
+for what this means to your build script.
+
+If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google
+Test will no longer compile.  This should affect very few people, as a
+large portion of STL (including <string>) doesn't compile in this mode
+anyway.  We decided to stop supporting it in order to greatly simplify
+Google Test's implementation.
+
+Developing Google Test
+----------------------
+
+This section discusses how to make your own changes to Google Test.
+
+### Testing Google Test Itself ###
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you can use CMake:
+
+  mkdir mybuild
+  cd mybuild
+  cmake -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Make sure you have Python installed, as some of Google Test's tests
+are written in Python.  If the cmake command complains about not being
+able to find Python ("Could NOT find PythonInterp (missing:
+PYTHON_EXECUTABLE)"), try telling it explicitly where your Python
+executable can be found:
+
+  cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Next, you can build Google Test and all of its own tests.  On *nix,
+this is usually done by 'make'.  To run the tests, do
+
+  make test
+
+All tests should pass.
+
+### Regenerating Source Files ###
+
+Some of Google Test's source files are generated from templates (not
+in the C++ sense) using a script.  A template file is named FOO.pump,
+where FOO is the name of the file it will generate.  For example, the
+file include/gtest/internal/gtest-type-util.h.pump is used to generate
+gtest-type-util.h in the same directory.
+
+Normally you don't need to worry about regenerating the source files,
+unless you need to modify them.  In that case, you should modify the
+corresponding .pump files instead and run the pump.py Python script to
+regenerate them.  You can find pump.py in the scripts/ directory.
+Read the Pump manual [2] for how to use it.
+
+  [2] http://code.google.com/p/googletest/wiki/PumpManual
+
+### Contributing a Patch ###
+
+We welcome patches.  Please read the Google Test developer's guide [3]
+for how you can contribute.  In particular, make sure you have signed
+the Contributor License Agreement, or we won't be able to accept the
+patch.
+

+Happy testing!

-// Google Test defines the testing::Message class to allow construction of
-// test messages via the << operator.  The idea is that anything

-// This allows a user to use his own types in Google Test assertions by
-// overloading the << operator.
-//
-// util/gtl/stl_logging-inl.h overloads << for STL containers.  These
-// overloads cannot be defined in the std namespace, as that will be
-// undefined behavior.  Therefore, they are defined in the global
-// namespace instead.

-// C++'s symbol lookup rule (i.e. Koenig lookup) says that these
-// overloads are visible in either the std namespace or the global
-// namespace, but not other namespaces, including the testing
-// namespace which Google Test's Message class is in.
-//
-// To allow STL containers (and other types that has a << operator
-// defined in the global namespace) to be used in Google Test assertions,
-// testing::Message must access the custom << operator from the global
-// namespace.  Hence this helper function.

-// Note: Jeffrey Yasskin suggested an alternative fix by "using
