+The goal of the Clang project is to create a new C, C++, Objective C
+and Objective C++ front-end for the LLVM compiler. Its tools are built
+as libraries and designed to be loosely-coupled and extensible.

+The Clang Static Analyzer consists of both a source code analysis
+framework and a standalone tool that finds bugs in C and Objective-C
+programs. The standalone tool is invoked from the command-line, and is
+intended to run in tandem with a build of a project or code base.
