Next you will need to prepare the GNU Autotools build system, if you
are using Linux, Mac OS X, or Cygwin. Enter the target directory of

-You can substitute newer versions of 'aclocal' and 'automake', but be aware
-that older versions are known not to work, and autoreconf may or may not
-correctly detect the required version. Also, the versions must match for both
-commands. However, this entire process will 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.
+Once you have completed this step, you are ready to build the library. Note

+If your system uses older versions of the autotools, the above command will
+fail. You may need to explicitly specify a version to use. For instance, if you

+1.4, use instead:
+
+ $ AUTOMAKE=automake-1.9 ACLOCAL=aclocal-1.9 autoreconf -fvi

+Make sure you're using the same version of automake and aclocal.

+subdirectory of the build tree, and it will be installed in the binary
+directory specified during the 'configure'. Here are some examples of its use,

Open the gtest.sln file in the msvc/ folder using Visual Studio, and
you are ready to build Google Test the same way you build any Visual
