+^^^^^^^^^^^^^^^^
+
+This directory contains a fragmentary C++ library that will allow
+to build only the simplest of C++ applications. In the deeply
+embedded world, that is probably all that is necessary. If you
+have a need for more extensive C++ support, the following libraries
+are recommended:
+
+ - libstdc++ (part of GCC)
+ - STLport http://www.stlport.org/
+ - uClibc++ http://cxx.uclibc.org/
+
+At present, only the following are supported here:
+
+ - void *operator new(std::size_t nbytes);
+ - void operator delete(void* ptr);
