-<p>At this point, Clang C++ is not production-quality and is not recommended for use beyond experimentation.  However, Clang C++ support
-is under active development and is progressing rapidly.  Please see the <a
-href="http://clang.llvm.org/cxx_status.html">C++ Status</a> page for details or
-ask on the mailing list about how you can help.</p>
-
-<p>Note that released Clang compilers will refuse to even try to use clang to compile C++ code unless you pass the <tt>-ccc-clang-cxx</tt> option to the driver. To turn on Clang's C++ support, please pass that flag. Clang compilers built from the Subversion trunk enable C++ support by default, and do not require the <tt>-ccc-clang-cxx</tt> flag.</p>
- 
-<p>Clang strives to strictly conform to the C++ standard.  That means
-it will reject invalid C++ code that another compiler may accept.  If
-Clang reports errors in your code, please check
-the <a href="http://clang.llvm.org/cxx_compatibility.html">C++
-Compatibility</a> page to see whether they are C++-conformance bugs
-and how you can fix them.</p>
