-------------
-Google Mock is not a testing framework itself. Instead, it needs a
-testing framework for writing tests. It works with Google Test
-(http://code.google.com/p/googletest/) out of the box. You can use

 These are the base requirements to build and use Google Mock from a source
 package (as described below):
+
   * GNU-compatible Make or "gmake"
   * POSIX-standard shell
   * POSIX(-2) Regular Expressions (regex.h)
-  * gcc 3.4 or newer.

   * Microsoft Visual C++ 8.0 SP1 or newer
 
 ### Mac OS X Requirements ###
+
   * Mac OS X 10.4 Tiger or newer
   * Developer Tools Installed
 
+Requirements for Contributors
+-----------------------------
+
+We welcome patches.  If you plan to contribute a patch, you need to
+build Google Mock and its own tests from an SVN checkout (described
+below), which has further requirements:
+
+  * Automake version 1.9 or newer

 Getting the Source
 ------------------
-There are two primary ways of getting Google Mock's source code: you can
-download a source release in your preferred archive format, or directly check
-out the source from a Version Control System (VCS, we use Google Code's
-Subversion hosting). The VCS checkout requires a few extra steps and some extra
-software packages on your system, but lets you track development, and make
-patches to contribute much more easily, so we highly encourage it.
-
-### VCS Checkout: ###
-The first step is to select whether you want to check out the main line of
-development on Google Mock, or one of the released branches. The former will be
-much more active and have the latest features, but the latter provides much
-more stability and predictability. Choose whichever fits your needs best, and
-proceed with the following Subversion commands:
 
-  svn checkout http://googlemock.googlecode.com/svn/trunk/ gmock-svn

-  svn checkout http://googlemock.googlecode.com/svn/branches/release-X.Y/ \
-    gmock-X.Y-svn
+Google Mock 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 needed to
+extract their contents, and the size of the resulting file.  Download
+whichever you are most comfortable with.
 
-Next you will need to prepare the GNU Autotools build system, if you

+To build Google Mock and your tests that use it, you need to tell your

-  tar -xvjf gmock-X.Y.Z.tar.bz2

+This section shows how you can integrate Google Mock into your
+existing build system.
+
+Suppose you put Google Mock in directory ${GMOCK_DIR} and Google Test
+in ${GTEST_DIR} (the latter is ${GMOCK_DIR}/gtest by default).  To
+build Google Mock, create a library build target (or a project as
+called by Visual Studio and Xcode) to compile
+
+  ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
+
+with
+
+  ${GTEST_DIR}/include, ${GTEST_DIR}, ${GMOCK_DIR}/include, and ${GMOCK_DIR}
+
+in the header search path.  Assuming a Linux-like system and gcc,
+something like the following will do:
+
+  g++ -I${GTEST_DIR}/include -I${GTEST_DIR} -I${GMOCK_DIR}/include \
+      -I${GMOCK_DIR} -c ${GTEST_DIR}/src/gtest-all.cc
+  g++ -I${GTEST_DIR}/include -I${GTEST_DIR} -I${GMOCK_DIR}/include \
+      -I${GMOCK_DIR} -c ${GMOCK_DIR}/src/gmock-all.cc
+  ar -rv libgmock.a gtest-all.o gmock-all.o
+
+Next, you should compile your test source file with
+${GTEST_DIR}/include and ${GMOCK_DIR}/include in the header search
+path, and link it with gmock and any other necessary libraries:
+
+  g++ -I${GTEST_DIR}/include -I${GMOCK_DIR}/include \
+      path/to/your_test.cc libgmock.a -o your_test
+
+As an example, the make/ directory contains a Makefile that you can
+use to build Google Mock on systems where GNU make is available
+(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
+Mock's own tests.  Instead, it just builds the Google Mock 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 ${GMOCK_DIR}/make
+  make
+  ./gmock_test
+
+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.
+
+### Windows ###
+
+The msvc/ directory contains VC++ 2005 projects for building Google
+Mock and selected tests.
+
+Open msvc/gmock.sln and build the library and tests.  If you want to
+create your own project to use with Google Mock, you'll have to
+configure it to use the gmock_config propety sheet.  For that:
+
+ * Open the Property Manager window (View | Other Windows | Property Manager)
+ * Right-click on your project and select "Add Existing Property Sheet..."
+ * Navigate to gmock_config.vsprops and select it.
+ * In Project Properties | Configuration Properties | General | Additional
+   Include Directories, type <path to Google Mock>/include.
+
+Tweaking Google Mock
+--------------------
+
+Google Mock 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 Mock 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 ${GTEST_DIR}/include/gtest/internal/gtest-port.h.

+### Choosing a TR1 Tuple Library ###
 
-Choosing a TR1 Tuple Library

 refer to the Boost website (http://www.boost.org/) for how to obtain
 it and set it up.
 
-Building the Source
--------------------
-### Linux and Mac OS X (without Xcode) ###
-There are two primary options for building the source at this point: build it
-inside the source code tree, or in a separate directory. We recommend building
-in a separate directory as that tends to produce both more consistent results
-and be easier to clean up should anything go wrong, but both patterns are
-supported. The only hard restriction is that while the build directory can be
-a subdirectory of the source directory, the opposite is not possible and will
-result in errors. Once you have selected where you wish to build Google Mock,
-create the directory if necessary, and enter it. The following steps apply for
-either approach by simply substituting the shell variable SRCDIR with "." for
-building inside the source directory, and the relative path to the source
-directory otherwise.
-
-  ${SRCDIR}/configure  # Standard GNU configure script, --help for more info
-
-Once you have successfully configured Google Mock, the build steps are standard
-for GNU-style OSS packages.
-
-  make  # Standard makefile following GNU conventions
-  make check  # Builds and runs all tests - all should pass
+### Tweaking Google Test ###
 
-Note that when building your project against Google Mock, you are building
-against Google Test as well. There is no need to configure Google Test
-separately.
+Most of Google Test's control macros apply to Google Mock as well.
+Please see file ${GTEST_DIR}/README for how to tweak them.
 
-### Windows ###
-The msvc/ directory contains VC++ 2005 projects for building Google
-Mock and selected tests.
+Upgrading from an Earlier Version
+---------------------------------
 
-If you want to use a version of Google Test other then the one bundled with
-Google Mock, change the value of the GTestDir macro in gmock_config.vsprop
-to point to the new location.
+We strive to keep Google Mock 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 Mock.
 
-Open msvc/gmock.sln and build the library and tests. If you want to
-create your own project to use with Google Mock, you'll have to
-configure it to use the gmock_config propety sheet. For that:
- * Open the Property Manager window (View | Other Windows | Property Manager)
- * Right-click on your project and select "Add Existing Property Sheet..."
- * Navigate to gmock_config.vsprops and select it.
- * In Project Properties | Configuration Properties | General | Additional
-   Include Directories, type <path to Google Mock>/include.
+### Upgrading from 1.2.0 or Earlier ###
 
-TODO(wan@google.com): update the .vsprops and .vcproj files such that the
-last step is unnecessary.
+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".
 
-### Using GNU Make ###
-The make/ directory contains a Makefile that you can use to build
-Google Mock on systems where GNU make is available (e.g. Linux and Mac
-OS X).  It doesn't try to build Google Mock's own tests.  Instead, it
-just builds the Google Mock libraries and some sample tests.  You can
-use it as a starting point for your own Makefile.

+Google Mock use it in order to be thread-safe.  For this to work, you

+you may need to do.
 
-  cd ${SRCDIR}/make
-  make
-  ./gmock_test
+If you have custom matchers defined using MatcherInterface or
+MakePolymorphicMatcher(), you'll need to update their definitions to
+use the new matcher API [2].  Matchers defined using MATCHER() or

-### Using Your Own Build System ###
-If none of the build solutions we provide works for you, or if you
-prefer your own build system, you just need to compile
-${GTEST_SRCDIR}/src/gtest-all.cc (where GTEST_SRCDIR is the root of
-the Google Test source tree) and src/gmock-all.cc into a library and
-link your tests with it.  Assuming a Linux-like system and gcc,

+This section discusses how to make your own changes to Google Mock.
+
+### Testing Google Mock 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'll need Autotools.  First, make sure you have followed
+the instructions in section "SVN Checkout" to configure Google Mock.
+Then, create a build output directory and enter it.  Next,
+
+  ${GMOCK_DIR}/configure  # Standard GNU configure script, --help for more info
+
+Once you have successfully configured Google Mock, the build steps are
+standard for GNU-style OSS packages.
+
+  make        # Standard makefile following GNU conventions
+  make check  # Builds and runs all tests - all should pass.
+
+Note that when building your project against Google Mock, you are building
+against Google Test as well.  There is no need to configure Google Test
+separately.
+
+### Regenerating Source Files ###
 
-Regenerating Source Files
--------------------------
