-  This is a test of the C++ standard library.  At present a port of the uClibc++
-  C++ library is available.  Due to licensing issues, the uClibc++ C++ library
-  is not included in the NuttX source tree by default, but must be installed
-  (see the README.txt file in the uClibc++ download package for installation).
-
-  The uClibc++ test includes simple test of:
-
-    - iostreams,
-    - STL,
-    - RTTI, and
-    - Exceptions
-
-  Example Configuration Options
-  -----------------------------
-    CONFIG_EXAMPLES_CXXTEST=y - Eanbles the example
-    CONFIG_EXAMPLES_CXXTEST_CXXINITIALIZE=y - By default, if CONFIG_HAVE_CXX
-      and CONFIG_HAVE_CXXINITIALIZE are defined, then this example
-      will call the NuttX function to initialize static C++ constructors.
-      This option may be disabled, however, if that static initialization
-      was performed elsewhere.
-
-  Other Required Configuration Settings
-  -------------------------------------
-  Other NuttX setting that are required include:
-
-    CONFIG_HAVE_CXX=y
-    CONFIG_HAVE_CXXINITIALIZE=y
-    CONFIG_UCLIBCXX=y
-
-  Additional uClibc++ settings may be required in your build environment.
