+Description:
+Google's framework for writing and using C++ mock classes on a variety of
+platforms (Linux, Mac OS X, Windows, Windows CE, Symbian, etc). Inspired by
+jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind, it can
+help you derive better designs of your system and write better tests.
+
+While gMock supports building with the Android NDK out-of-the-box, it needs some
+small modifications to build as part of the Android OS build.  Specifically, it
+needs a different format of build script, and it needs to build against the OS'
+modified version of gTest, rather than the packaged version.
