//  This file implements the CommonOptionsParser class used to parse common
//  command-line options for clang tools, so that they can be run as separate
//  command-line applications with a consistent common interface for handling
//  compilation database and input files.
//
//  It provides a common subset of command-line options, common algorithm
//  for locating a compilation database and source files, and help messages
//  for the basic command-line interface.
//
//  It creates a CompilationDatabase and reads common command-line options.
//
//  This class uses the Clang Tooling infrastructure, see
//    http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
//  for details on setting it up with LLVM source tree.
