%description
clang: noun
    1. A loud, resonant, metallic sound.
    2. The strident call of a crane or goose.
    3. C-language family front-end toolkit.

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.

%package libs

Runtime library for clang.

%package devel

%package analyzer
Summary:	A source code analysis framework

BuildArch:	noarch
Requires:	%{name} = %{version}-%{release}
# not picked up automatically since files are currently not installed in
# standard Python hierarchies yet
Requires:	python

%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.

%package tools-extra
Summary: Extra tools for clang
Requires: llvm-libs%{?_isa} = %{version}
Requires: clang-libs%{?_isa} = %{version}

%description tools-extra
A set of extra tools built using Clang's tooling API.
