Clang is an LLVM native C/C++/ObjC compiler, which aims to deliver
amazingly fast compiles, extremely useful error and warning messages and
to provide a platform for building great source level tools. The 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.
