 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.
 
-#### Build
+### Build with CMake
 
-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](https://github.com/google/googletest/blob/master/CMakeLists.txt))
 that can be used on a wide range of platforms ("C" stands for cross-platform.).

-### Legacy Build Scripts
+#### C++ Standard Version
 
-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 above sections to
-integrate Google Test with your existing build system.
+An environment that supports C++11 is required in order to successfully build
+Google Test. One way to ensure this is to specify the standard in the top-level
+project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
+is not feasible, for example in a C project using Google Test for validation,
+then it can be specified by adding it to the options for cmake via the
+`DCMAKE_CXX_FLAGS` option.
 
-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).

-### 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.).

-// Value-parameterized tests allow you to test your code with different
-// parameters without writing multiple copies of the same test.
-//
-// Here is how you use value-parameterized tests:
-
-#if 0
-
-// To write value-parameterized tests, first you should define a fixture
-// class. It is usually derived from testing::TestWithParam<T> (see below for
-// another inheritance scheme that's sometimes useful in more complicated
-// class hierarchies), where the type of your parameter values.
-// TestWithParam<T> is itself derived from testing::Test. T can be any
-// copyable type. If it's a raw pointer, you are responsible for managing the
-// lifespan of the pointed values.
-
-class FooTest : public ::testing::TestWithParam<const char*> {
-  // You can implement all the usual class fixture members here.
-};
-
-// Then, use the TEST_P macro to define as many parameterized tests
-// for this fixture as you want. The _P suffix is for "parameterized"
-// or "pattern", whichever you prefer to think.
-
-TEST_P(FooTest, DoesBlah) {
-  // Inside a test, access the test parameter with the GetParam() method
-  // of the TestWithParam<T> class:
-  EXPECT_TRUE(foo.Blah(GetParam()));
-  ...
-}
-
-TEST_P(FooTest, HasBlahBlah) {
-  ...
-}
-
-// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
-// case with any set of parameters you want. Google Test defines a number
-// of functions for generating test parameters. They return what we call
-// (surprise!) parameter generators. Here is a summary of them, which
-// are all in the testing namespace:
-//
-//
-//  Range(begin, end [, step]) - Yields values {begin, begin+step,
-//                               begin+step+step, ...}. The values do not
-//                               include end. step defaults to 1.
-//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
-//  ValuesIn(container)        - Yields values from a C-style array, an STL
-//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
-//  Bool()                     - Yields sequence {false, true}.
-//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
-//                               for the math savvy) of the values generated
-//                               by the N generators.
-//
-// For more details, see comments at the definitions of these functions below
-// in this file.
-//
-// The following statement will instantiate tests from the FooTest test case
-// each with parameter values "meeny", "miny", and "moe".
-
-INSTANTIATE_TEST_CASE_P(InstantiationName,
-                        FooTest,
-                        Values("meeny", "miny", "moe"));
-
-// To distinguish different instances of the pattern, (yes, you
-// can instantiate it more then once) the first argument to the
-// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
-// actual test case name. Remember to pick unique prefixes for different
-// instantiations. The tests from the instantiation above will have
-// these names:
-//
-//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
-//    * InstantiationName/FooTest.DoesBlah/1 for "miny"
-//    * InstantiationName/FooTest.DoesBlah/2 for "moe"
-//    * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
-//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
-//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
-//
-// You can use these names in --gtest_filter.
-//
-// This statement will instantiate all tests from FooTest again, each
-// with parameter values "cat" and "dog":
-
-const char* pets[] = {"cat", "dog"};
-INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));
-
-// The tests from the instantiation above will have these names:
-//
-//    * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
-//
-// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
-// in the given test case, whether their definitions come before or
-// AFTER the INSTANTIATE_TEST_CASE_P statement.
-//
-// Please also note that generator expressions (including parameters to the
-// generators) are evaluated in InitGoogleTest(), after main() has started.
-// This allows the user on one hand, to adjust generator parameters in order
-// to dynamically determine a set of tests to run and on the other hand,
-// give the user a chance to inspect the generated tests with Google Test
-// reflection API before RUN_ALL_TESTS() is executed.
-//
-// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
-// for more examples.
-//
-// In the future, we plan to publish the API for defining new parameter
-// generators. But for now this interface remains part of the internal
-// implementation and is subject to change.
-//
-//
-// A parameterized test fixture must be derived from testing::Test and from
-// testing::WithParamInterface<T>, where T is the type of the parameter
-// values. Inheriting from TestWithParam<T> satisfies that requirement because
-// TestWithParam<T> inherits from both Test and WithParamInterface. In more
-// complicated hierarchies, however, it is occasionally useful to inherit
-// separately from Test and WithParamInterface. For example:
-
-class BaseTest : public ::testing::Test {
-  // You can inherit all the usual members for a non-parameterized test
-  // fixture here.
-};
-
-class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
-  // The usual test fixture members go here too.
-};
-
-TEST_F(BaseTest, HasFoo) {
-  // This is an ordinary non-parameterized test.
-}
-
-TEST_P(DerivedTest, DoesBlah) {
-  // GetParam works just the same here as if you inherit from TestWithParam.
-  EXPECT_TRUE(foo.Blah(GetParam()));

-// Range(start, end, step)
-//   - returns a generator producing a sequence of values {start, start+step,
-//     start+step+step, ..., }.
-// Notes:
-//   * The generated sequences never include end. For example, Range(1, 5)

-//     returns a generator producing {1, 3, 5, 7}.
-//   * start and end must have the same type. That type may be any integral or

-//     * It must have operator+() (operator+(int-compatible type) for
-//       two-operand version).
-//     * It must have operator<() defined.

+// This is an advanced API only to be used when the `TEST` macros are
+// insufficient. The macros should be preferred when possible, as they avoid
+// most of the complexity of calling this function.
+//
+// The `factory` argument is a factory callable (move-constructible) object or
+// function pointer that creates a new instance of the Test object. It
+// handles ownership to the caller. The signature of the callable is
+// `Fixture*()`, where `Fixture` is the test fixture class for the test. All
+// tests registered with the same `test_suite_name` must return the same
+// fixture type. This is checked at runtime.
+//
+// The framework will infer the fixture class from the factory and will call
+// the `SetUpTestSuite` and `TearDownTestSuite` for it.
+//
+// Must be called before `RUN_ALL_TESTS()` is invoked, otherwise behavior is
+// undefined.
+//
+// Use case example:
+//
+// class MyFixture : public ::testing::Test {
+//  public:

-// A "smart" pointer type with reference tracking.  Every pointer to a
-// particular object is kept on a circular linked list.  When the last pointer
-// to an object is destroyed or reassigned, the object is deleted.
-//
-// Used properly, this deletes the object when the last reference goes away.
-// There are several caveats:
-// - Like all reference counting schemes, cycles lead to leaks.
-// - Each smart pointer is actually two pointers (8 bytes instead of 4).
-// - Every time a pointer is assigned, the entire list of pointers to that
-//   object is traversed.  This class is therefore NOT SUITABLE when there
-//   will often be more than two or three pointers to a particular object.
-// - References are only tracked as long as linked_ptr<> objects are copied.
-//   If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
-//   will happen (double deletion).
-//
-// A good use of this class is storing object references in STL containers.
-// You can safely put linked_ptr<> in a vector<>.
-// Other uses may not be as good.
-//
-// Note: If you use an incomplete type with linked_ptr<>, the class
-// *containing* linked_ptr<> must have a constructor and destructor (even
-// if they do nothing!).
-//
-// Bill Gibbons suggested we use something like this.
-//
-// Thread Safety:
-//   Unlike other linked_ptr implementations, in this implementation
-//   a linked_ptr object is thread-safe in the sense that:
-//     - it's safe to copy linked_ptr objects concurrently,
-//     - it's safe to copy *from* a linked_ptr and read its underlying
-//       raw pointer (e.g. via get()) concurrently, and
-//     - it's safe to write to two linked_ptrs that point to the same
-//       shared object concurrently.
-// FIXME: rename this to safe_linked_ptr to avoid
-// confusion with normal linked_ptr.

-//    #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]

-//                                      // not a compile-time constant.
-//
-// - By using the type CompileAssert<(bool(expr))>, we ensures that
-//   expr is a compile-time constant.  (Template arguments must be
-//   determined at compile-time.)
-//
-// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
-//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
