+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, and Symbian). 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 mailing lists
+for questions, discussions, and development. There is also an IRC channel on
+OFTC (irc.oftc.net) #gtest available. Please join us!
+
+Requirements
+------------
+Google Test is designed to have fairly minimal requirements to build and use
+with your projects, but there are some. Currently, the only Operating System
+(OS) on which Google Test is known to build properly is Linux, but we are
+actively working on Windows and Mac support as well. The source code itself is
+already portable across many other platforms, but we are still developing
+robust build systems for each.
+
+### 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 standards compliant compiler
+
+Furthermore, if you are building Google Test from a VCS Checkout (also
+described below), there are further requirements:
+  * Automake version 1.9 or newer
+  * Autoconf version 2.59 or newer
+  * Libtool / Libtoolize
+  * Python version 2.4 or newer
+
+Getting the Source
+------------------
+There are two primary ways of getting Google Test'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 Test, 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://googletest.googlecode.com/svn/trunk/ gtest-svn
+
+or for a release version X.Y.*'s branch:
+
+  $ svn checkout http://googletest.googlecode.com/svn/branches/release-X.Y/ gtest-X.Y-svn
+
+Next you will need to prepare the GNU Autotools build system. Enter the
+target directory of the checkout command you used ('gtest-svn' or
+'gtest-X.Y-svn' above) and proceed with the following commands:
+
+  $ aclocal-1.9  # Where "1.9" must match the following automake command
+  $ libtoolize -c
+  $ autoheader
+  $ automake-1.9 -ac  # See Automake version requirements above
+  $ autoconf
+
+While this is a bit complicated, it will most often be automatically re-run by
+your "make" invocations, so in practice you shouldn't need to worry too much.
+Once you have completed these steps, you are ready to build the library. 
+
+### Source Package: ###
+Google Test is also released in source packages which can be downloaded from
+its Google Code 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] Google Test Downloads: http://code.google.com/p/googletest/downloads/list
+
+Once downloaded expand the archive using whichever tools you prefer for that
+type. This will always result in a new directory with the name "gtest-X.Y.Z"
+which contains all of the source code. Here are some examples in Linux:
+
+  $ tar -xvzf gtest-X.Y.Z.tar.gz
+  $ tar -xvjf gtest-X.Y.Z.tar.bz2
+  $ unzip gtest-X.Y.Z.zip
+
+Building the Source
+-------------------
+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 Test,
+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
+  $ make  # Standard makefile following GNU conventions
+  $ make check  # Builds and runs all tests - all should pass
+
+Other programs will only be able to use Google Test's functionality if you
+install it in a location which they can access, in Linux this is typically
+under '/usr/local'. The following command will install all of the Google Test
+libraries, public headers, and utilities necessary for other programs and
+libraries to leverage it:
+
+  $ sudo make install  # Not necessary, but allows use by other programs
+
+TODO(chandlerc@google.com): This section needs to be expanded when the
+'gtest-config' script is finished and Autoconf macro's are provided (or not
+provided) in order to properly reflect the process for other programs to
+locate, include, and link against Google Test.
+
+Finally, should you need to remove Google Test from your system after having
+installed it, run the following command, and it will back out its changes.
+However, note carefully that you must run this command on the *same* Google
+Test build that you ran the install from, or the results are not predictable.
+If you install Google Test on your system, and are working from a VCS checkout,
+make sure you run this *before* updating your checkout of the source in order
+to uninstall the same version which you installed.
+
+  $ sudo make uninstall  # Must be run against the exact same build as "install"
+
+Happy testing!

+// executed:
+//
+//   1. The assertion fails immediately if there are more than one
+//   active threads.  This is because it's safe to fork() only when
+//   there is a single thread.
+//
+//   2. The parent process forks a sub-process and runs the death test
+//   in it; the sub-process exits with code 0 at the end of the death
+//   test, if it hasn't exited already.
+//
+//   3. The parent process waits for the sub-process to terminate.
+//
+//   4. The parent process checks the exit code and error message of
+//   the sub-process.
+//
+// Note:
+//
+// It's not safe to call exit() if the current process is forked from
+// a multi-threaded process, so people usually call _exit() instead in
+// such a case.  However, we are not concerned with this as we run
+// death tests only when there is a single thread.  Since exit() has a
+// cleaner semantics (it also calls functions registered with atexit()
+// and on_exit()), this macro calls exit() instead of _exit() to
+// terminate the child process.

+//
+//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+//   for (int i = 0; i < 5; i++) {

+// Typical usage:

+//   1. You stream a bunch of values to a Message object.

+//   2. Then you stream the Message object to an ostream.
+//      This causes the text in the Message to be streamed

+//
+// For example;

+//
+// will print "1 != 2".

+//   ASSERT_PRED_FORMAT1(pred_format, v1)
+//   ASSERT_PRED_FORMAT2(pred_format, v1, v2)
+//   ...
+//
+// where pred_format is a function or functor that takes n (in the
+// case of ASSERT_PRED_FORMATn) values and their source expression
+// text, and returns a testing::AssertionResult.  See the definition
+// of ASSERT_EQ in gtest.h for an example.
+//
+// If you don't care about formatting, you can use the more
+// restrictive version:
+//
+//   ASSERT_PRED1(pred, v1)
+//   ASSERT_PRED2(pred, v1, v2)
+//   ...
+//
+// where pred is an n-ary function or functor that returns bool,
+// and the values v1, v2, ..., must support the << operator for
+// streaming to std::ostream.
+//
+// We also define the EXPECT_* variations.
