 Clang project is a C, C++, Objective C and Objective C++ front-end
 for the LLVM compiler. Its goal is to offer a replacement to the GNU Compiler
 Collection (GCC).
 .
 Clang implements all of the ISO C++ 1998 and 2001 standards and also provides
 a partial support of C++1y.
 .
 This package contains the clang headers to develop extensions over
 libclang1-3.4.
