[cfe-dev] Clang Tooling: Run multiple tools with different args

To parse the command line arguments myself, I used some code from the
CommonOptionsParsers constrcutor. I don't understand the sourcePaths
population though. How is this list used and how is this populated? I
searched through the LLVM source code and found no usage of sourcePaths
anywhere? Can you provide a little more detail on how llvm command line
parser and the clang parser (options after "--") work?
