+Installation with xcodebuild requires specifying an installation desitination

+xcodebuild:
+
+  $DSTROOT/Library/Frameworks/gtest.framework
+  $DSTROOT/usr/local/lib/libgtest.a
+  $DSTROOT/usr/local/lib/libgtest_main.a
+  
+You specify the installation directory on the command line with the other
+xcodebuild options. Here's how you would install in a user-visible location:
+
+  xcodebuild install DSTROOT=~
+  
+To perform a system-wide inistall, escalate to an administrator and specify
+the file system root as the DSTROOT:
+
+  sudo xcodebuild install DSTROOT=/
+
+To uninstall gtest.framework via the command line, you need to delete the three
+items listed above. Remember to escalate to an administrator if deleting these
+from the system-wide location using the commands listed below:
+
+  sudo rm -r /Library/Frameworks/gtest.framework
+  sudo rm /usr/local/lib/libgtest.a
+  sudo rm /usr/local/lib/libgtest_main.a
 
 It is also possible to build and execute individual tests within Xcode. Each
 test has its own Xcode "Target" and Xcode "Executable". To build any of the
 tests, change the active target and the active executable to the test of
 interest and then build and run.
 
-NOTE: Several tests use a Python script to run the test executable. These can be
-run from Xcode by creating a "Custom Executable". For example, to run the Python
-script which executes the gtest_color_test, select the Project->New Custom
-Executable... menu item. When prompted, set the "Executable Name" to something
-like "run_gtest_color_test" and set the "Executable Path" to the path of the
-gtest_color_test.py script. Finally, choose "Run" from the Run menu and check
-the Console for the results.
