+llvm: The LLVM Compiler Infrastructure, including the Clang C/C++/Objective-C compiler
+======================================================================================
+
+Description
+-----------
+
+The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
+
+Clang is an "LLVM native" C/C++/Objective-C compiler.
+
+The libc++ and libc++ ABI projects provide a standard conformant and high-performance
+implementation of the C++ Standard Library, including full support for C++11 and C++14.
