+SUMMARY="A llvm front end compiler for C and C++" 
+DESCRIPTION="
+Clang is an 'LLVM native' C/C++/Objective-C compiler, which aims to deliver \
+amazingly fast compiles (e.g. about 3x faster than GCC when compiling \
+Objective-C code in a debug configuration), extremely useful error and warning \
+messages and to provide a platform for building great source level tools.
