                        the LLVM intermediate representation ("LLVM IR").

		    long_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. The included Clang \
		                        Static Analyzer is a tool that automatically finds bugs in \
		                        your code, and is a great example of the sort of tool \
		                        that can be built using the Clang frontend as a \
		                        library to parse C/C++ code.
