%description
The Clang project provides a language front-end and tooling infrastructure for\
languages in the C language family (C, C++, Objective C/C++, OpenCL, CUDA, and\
RenderScript) for the LLVM project. Both a GCC-compatible compiler driver (clang)\
and an MSVC-compatible compiler driver (clang-cl.exe) are provided.\

%description analyzer
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.
