/// \file
/// \brief This file implements the C++11 feature migration tool main function
/// and transformation framework.
///
/// Usage:
/// cpp11-migrate [-p <build-path>] <file1> <file2> ... [-- [compiler-options]]
///
/// Where <build-path> is a CMake build directory containing a file named
/// compile_commands.json which provides compiler options for building each
/// sourc file. If <build-path> is not provided the compile_commands.json file
/// is searched for through all parent directories.
///
/// Alternatively, one can provide compile options to be applied to every source
/// file after the optional '--'.
///
/// <file1>... specify the paths of files in the CMake source tree, with the
/// same requirements as other tools built on LibTooling.
